Description

FIELD OF THE INVENTION

The present invention relates to a portable visual display device for an electrical or electronic measuring device and to a measuring station arrangement with such a display device.

TECHNICAL BACKGROUND

The present invention is in the field of so-called head-mounted displays (literally "head-mounted displays") or short HMD, which are understood to mean on the head of a person worn visual output devices. It presents images either on a near-eye screen or projects directly onto the retina. Representatives of such head-mounted display are the so-called EyeTap and Google Glass.

EyeTap refers to a monocle-like head-mounted display, which is worn in front of the eye and which combines the function of a camera and a display. EyeTap displays computer-generated images in the user-perceived scene. Unlike virtual reality, where the user's field of vision is shielded by an appropriate helmet, the EyeTap user continues to perceive his surroundings.

Google Glass is the brand name of another representative of a Google Inc. head-mounted display. Google Glass is a miniature, miniature, computer-mounted monitor mounted on a goggle frame that displays information in the field of view using a head-up display. For example, a Google Glass based head-mounted display is in the WO 2013/025672 A2 as well as the US 2012/0299870 A1 described.

The present invention is also in the field of electrical measuring and testing technology. In the case of electrical measuring and test technology, a test object to be tested, the so-called device under test or DUT, which can be a wafer, a single component, an assembly, an integrated circuit or a complete device, is tested or tested. Testing is done by measuring physical parameters. When it comes to measuring and testing technology, the test engineer is often faced with the task of electrically contacting the test object with suitable probes, at the same time entering corresponding measurement parameters and, in addition, monitoring the measuring curves on the measuring device. This is not trivial, especially in the case of complex measurement objects and / or with a large number of parameters to be measured, since sometimes there is no free view of the screen of the measuring device or the display is hidden, for example by the arms of the test engineer. Frequently, however, an attempt to observe the screen nevertheless leads to undesired slippage of the probes, which however can falsify the measurement, as a result of which the entire series of measurements would have to be carried out again. This is time consuming and unproductive.

SUMMARY OF THE INVENTION

Against this background, there is a need to facilitate the testing of DUTs to be tested.

For this purpose, the invention provides a display device with the features of patent claim 1 and / or a measuring station arrangement with the features of claim 22.

• – Ein tragbares visuelles Anzeigegerät für ein elektrisches oder elektronisches Messgerät, wobei die Anzeigegerät in Form einer elektronischen Brille ausgebildet ist und aufweist: ein Brillenrahmen mit mindestens einem darin vorhandenen Brillenglas, eine Kommunikationsschnittstelle, über welche die Anzeigegerät mit einem Messgerät koppelbar ist und über welche Mess- und/oder Steuerdaten des Messgeräts aufnehmbar sind, zumindest ein Display zur optischen Signalisierung und Darstellung von Bildinformationen, welches zumindest einem Brillenglas zugeordnet ist, eine Display-Steuereinrichtung zur Steuerung der Funktion des zumindest einen Displays, welche mit der Kommunikationsschnittstelle und dem zumindest einen Display gekoppelt ist und welche derart ausgebildet ist, um über die Kommunikationsschnittstelle aufgenommene Messdaten und/oder andere optische Informationen auf dem zumindest einen Display anzuzeigen.
• – Eine Messplatzanordnung, mit einem Tastkopf, welcher dazu ausgebildet ist, mindestens einen physikalischen Parameter eines Messobjektes aufzunehmen, mit einem über eine erste Schnittstelle mit dem Tastkopf gekoppelten Messgerät zum Testen des Messobjektes, wobei das Messgerät dazu ausgebildet ist, den von dem Tastkopf aufgenommenen physikalischen Parameter auszuwerten, mit einem erfindungsgemäßen Anzeigegerät, welches über eine zweite Schnittstelle mit dem Messgerät und/oder dem Tastkopf gekoppelt ist.

Accordingly, it is provided:

• - A portable visual display device for an electrical or electronic measuring device, wherein the display device is in the form of electronic glasses and comprises: a spectacle frame with at least one spectacle lens therein, a communication interface, via which the display device can be coupled with a measuring device and via which Mess - and / or control data of the measuring device are receivable, at least one display for visual signaling and display of image information, which is associated with at least one lens, a display control device for controlling the function of the at least one display, which communicates with the communication interface and the at least one display is coupled and which is designed so as to display on the communication interface recorded measurement data and / or other optical information on the at least one display.
• A measuring station arrangement with a probe, which is designed to receive at least one physical parameter of a measuring object, with a measuring device coupled to the probe via a first interface for testing the measuring object, the measuring device being designed to detect the physical image recorded by the probe Evaluate parameters with a display device according to the invention, which is coupled via a second interface with the measuring device and / or the probe.

One finding of the present invention is that it is uncomfortable for a test engineer to concentrate on the one hand on contacting the probe and, on the other hand, in the context of testing or checking required monitoring of a screen.

The idea underlying the present invention is to provide a portable and thus mobile visual display device in addition to or as an alternative to a conventional screen provided in the measuring device. This mobile display device is in the form of electronic glasses. The mobile display device or the electronic glasses has a display and a communication interface to the measuring device. In this way, information of the measuring device, which relate for example to the current measurement, can be transmitted to the mobile display device and displayed by means of the display. For this purpose, the electronic spectacles are typically set up by a test engineer who is currently testing a test object during the test procedure. Via the display, corresponding measurement information of a current test procedure can be displayed directly on the display, without the test engineer having to move his head away during a test procedure and without being distracted from the test procedure performed on the test object. The test engineer receives on the display as needed visual image information, the z. B. relate to the ongoing test process.

The particular advantage of the present invention is that the test procedure is significantly simplified by means of such a mobile display device, since the test engineer is no longer distracted from the test procedure itself or from a corresponding handling. He can concentrate fully on the test procedure and thus receives the corresponding measurement information on the display of the portable display device in a parallel manner - without having to turn his head away from the measurement object or without having to change his position. This reduces the likelihood that probes will slip off the test object during a test procedure. The entire measurement is thus simpler and more comfortable.

Advantageous embodiments and further developments will become apparent from the other dependent claims and from the description with reference to the figures of the drawing.

In a particularly preferred embodiment, a wireless communication interface is provided, via which the display device can establish wireless data communication with a measuring device coupled to it. In this way, a user of the display device or the meter is not affected by a connecting line between the electronic glasses and the meter, which facilitates the overall measurement and testing. However, it must be ensured that this communication interface does not affect the measurement process, the measurement result and / or the parameters to be measured.

In a particularly preferred embodiment, the display is designed as a head-up display (or short HUD). In a head-up display, a user can maintain his head posture and / or viewing direction since information about the head-up display is projected directly into his field of vision. Head-up displays generally consist of an imaging unit, an optical module and a projection surface. In this case, the imaging unit generates the image, which is passed via the optical module with collimator and deflection on a projection screen. This projection can z. B. be formed by a specular, translucent spectacle lens. The advantage is that on the one hand the user can recognize the image information which is displayed via the head-up display on the one hand because of the transparency of the spectacle lenses, that is to say he receives the mirrored information of the imaging unit. In addition, the user perceives the real world behind the lenses, such as the measurement setup, the probes, and the DUT. The generated virtual image can be projected onto the screen so as to be detected by a single eye (monocular) or both eyes (binocular) of the user.

In an alternative embodiment, the display is designed as at least partially transparent screen. This partially transparent screen can be arranged, for example, in a partial region of a spectacle lens. In a preferred embodiment, for example, a partially transparent LCD film may be provided as a screen. A user receives via the screen or the LCD film corresponding image information displayed directly on a respective lens and takes due to the partial transparency still aware of the environmental information behind the lens.

In one embodiment, the display is at least partially transparent and preferably completely transparent in the deactivated state. In the deactivated state, the display thus does not affect the actual function of the spectacles, so that a user has a completely free field of view. Transparency in terms of optics in this context means the permeability of the material of the spectacle lens for light waves. Complete transparency in this context means that (almost) all light waves are transmitted through the spectacle lens, whereas partial transparency means that a significant portion of the light waves are transmitted, so that the spectacle lenses cause only a darkening, but not complete shading.

In a particularly preferred embodiment, the display is arranged in one of the lenses or assigned to one of the lenses so that it is arranged in the intended use of the glasses in a secondary field of view of the eye. In this way, it is possible for a user to perceive the environment in the primary field of view of the eye almost unhindered. Only in the event that a user wants to perceive the image information displayed by the display, he can do so by a movement of the pupil toward the secondary field of view of the eye. This also ensures that the display and the image information displayed by it support the user during the measuring and testing process, but do not disturb it.

In one embodiment of the invention, a single display is provided, which is assigned to exactly one spectacle lens. A user thus has at least the second lens a free, unobstructed view. The only display fills in the activated state of this lens at least partially and in particular completely so, so that the image information is displayed on a part or in the entire lens.

In a particularly preferred embodiment, each lens is assigned its own display, d. H. one display for the left lens and one display for the right lens. These two displays could be designed to display different image information. For example, it would be conceivable for a first display to represent respective measured values, measurement series, signal time diagrams of the measured signals, while, for example, the second display provides an enlargement of the measurement setup. Conceivable, of course, would be other constellations. This would allow a user to select on which of the two lenses the image information should be displayed. Advantageously, a respective display can be activated and deactivated as required and independently of the respective other display.

In a preferred embodiment, an input device is provided, which is coupled to the display control device and via which user-specific input information can be entered. For example, control information for the display control device, operating information and the like can be input via the input device. In addition, programming of the display device would also be possible via the input device. It would be conceivable, for example, that a zoom function, a display area on the display, the camera, the display and the like be controlled via the input device.

In a particularly preferred embodiment, a non-contact input device is provided. This makes a very comfortable input that is very easy for the user possible. The user can make contactless user-specific inputs during testing without being distracted from the measurement process by manual movements. The user thus receives an additional degree of freedom during the measuring process, which increases the comfort, especially in the case of very complex measuring and testing processes.

In a preferred embodiment, the input device is designed as an acceleration sensor, which is coupled to, for example, the spectacle frame or a spectacle lens. An acceleration sensor refers to a sensor that measures an acceleration and is thus sensitive to movement. The acceleration sensor is designed in such a way, for example, to detect a jerky movement of the display device or the glasses in at least one direction and to supply the display control device with control information which contains information about the detected movement, depending on the jerky movement thus detected. Preferably, a linear acceleration, ie an acceleration in a predetermined direction, is measured. Thus, by means of a linear acceleration sensor, two pieces of information can be recorded, namely first information in one direction and second information in the opposite direction. In addition, it would be conceivable to provide a plurality of acceleration sensors, which are each sensitive to an acceleration in a different direction. Preferably, two acceleration sensors are provided, wherein a first acceleration sensor is sensitive to a head nod, ie a movement of the head down and up. For example, a second acceleration sensor may be sensitive to a head shake, ie a movement of the head to the left and to the right. In this way, four input information can be entered by a jerky head movement. In addition, other acceleration sensors could be used which are sensitive to other directions.

Additionally or alternatively, provided as an input device provided on the eyeglass frame button, keyboard and / or touchpad. After such an input device is present on the eyeglass frame and thus is not visible in the intended use of the electronic glasses, it is advantageous if a haptic coding of the keys is present, so that the user can recognize the respective keys by a suitable structure of the surface. Typically, though not necessarily, this input device is on the side eyeglass frame attached so that it does not affect the field of view of a user in the intended use of electronic glasses.

In a further additional or alternative embodiment, a first motion sensor is provided as the input device. This first motion sensor is arranged and positioned in such a way as to recognize a wink of the user in the intended use of the spectacles and to supply control information to the display control device as a function of the detected winking. Additionally or alternatively, it may also be provided that the first motion sensor detects not only a wink, but also, for example, a number of winks or their frequency. The particular advantage is that an input can be coded by a user by winking, the number of consecutive wink events and / or their frequency. The display control device is then able to decode the thus recognized winking information accordingly.

In a further embodiment, the input device may comprise a second motion sensor, which is arranged and positioned to recognize gestures of the user in the intended use of the electronic glasses and to supply control information to the display control device as a function of the recognized gestures. Gesture recognition is a branch of computer science and deals with algorithms and mathematical methods for the automatic recognition of human gestures and the use of such gestures for human-computer interaction. For example, every posture and body movement can in principle be interpreted as a gesture. By means of the second motion sensor can be detected in this way according to predetermined gestures, wherein the display control means assigns a detected gesture of a control information or a user-specific input. This is a very elegant non-contact input option, which additionally facilitates the measurement process for the user, since he does not have to press a keyboard that is specifically available for the corresponding input.

In a further, additional or alternative embodiment, a camera is provided, which is designed to record a video sequence, an image or a pattern. The camera can be designed, for example, as a CCD camera. The video sequence recorded by the camera, images, patterns, etc. can be displayed on the display in one embodiment. Additionally or alternatively, it would also be conceivable to use the camera as an input device, wherein the video sequence, image, pattern, etc. contains an input information which is evaluated by the display control device and assigned to a control information. For example, it would be conceivable for a user to record image information by looking at a bar code, a QR code or the like, which is also recorded by the camera when the camera is aligned appropriately. This image information can be decoded by the display control device and assigned to a control information. It would also be conceivable for the user to actuate a visually accessible keyboard by appropriate glances by optically fixing the various keys of a keyboard, which is recognized by the camera. In this way, entire control commands can be entered by optical input using the camera.

In a further embodiment, a pattern recognition device is provided, which is designed to recognize the image or pattern recorded by the camera, in particular a QR code or bar code. This pattern recognition device can be part of the camera and / or the display control device or can also be designed as a separate device. It would also be conceivable that the layout of a circuit board, an integrated circuit and similar layout structures are detected by means of the pattern recognition device.

In a particularly preferred embodiment, the display control device has a zoom function, by means of which image information displayed by the display can be increased or reduced as required. The user can in this way z. B. enlarge or reduce a section of the image information displayed on the display. For example, in this way the measuring range can be increased or several image information can be displayed by reducing it on the display.

In one embodiment, the display control device is designed to display recorded measurement data as a signal-time diagram on the display. The measured data are preferably displayed as time-continuous signal-time diagrams. The user can thus follow the course of a current measurement directly. Additionally or alternatively, it would also be conceivable that the display control device is designed to display recorded measurement data as a signal frequency diagram on the display.

In an alternative embodiment, the display control device is designed to display recorded measurement data as digital values, in particular as mean values, on the display. This is useful if the test engineer z. B. not by an excessive amount Measurement information should be flooded. Additionally or alternatively, it would also be conceivable to use only upper and lower threshold values, marker values, ie individual values taken out of a measurement curve selectively by a marker, threshold value exceedances, eg. Example, as a traffic light display or Yes-No display, and the like on the display.

In a further embodiment, the display control device is designed to display CAD information and / or design information of the measurement object on the display. This CAD information or design information wins the display control device, for example via the meter itself or about the image information recorded by the camera.

In one embodiment of the measuring station arrangement according to the invention, its probe has programmable keys. By means of these programmable keys, the function of the probe can be programmed user-specifically, for example such that, for example, by pressing the keys, the value of a currently measured physical parameter is displayed on the display of the display device. In addition, other programming would be conceivable, such as switching a measuring range, increasing a measuring range, activating and / or deactivating the display of the display device, activating and / or deactivating a camera, etc.

Under a probe, which is also referred to as a measuring head or probe divider, a measuring means in the electronics to understand. The probe is connected to a device under test, the so-called measuring object, and forwards the measured signal to the measuring device. There are probes for measuring a variety of physical parameters, such as voltage, current, frequency, temperature and the like. Smart probes already contain electronic components to compensate for measurement errors. There are a variety of different probe types, depending on the application, the appropriate probe must be selected for each measurement.

In a further, likewise preferred embodiment, the probe head has a probe camera. This probe camera is arranged and adapted to record a video sequence, an image and / or a pattern of the measurement object or a part thereof and display it via the display of the display device. The probe camera can be understood in a further embodiment as part of an input device for the display device when, for example, receives patterns on a measurement object and interpreted as part of an input. Particularly advantageous is the probe camera in conjunction with a zoom function of the display control device, since thereby the positioning and thus the contact of the probe is facilitated to a provided for contacting area of the measurement object.

In a further embodiment, the probe and / or the display device are wirelessly coupled to the meter. In this way, it is effectively prevented that connecting lines between the probe or the display device and the measuring device impair the operation of the measuring device and in particular the measuring process performed therewith.

In a further embodiment, the display device is designed such that its display control device activates the display only when the probe is in contact with the test object to be tested. In a first variant it can be provided that the probe is brought into electrical contact with the corresponding measurement object. In addition, it would also be conceivable that the display is already activated when the probe mechanically contacts, for example, any point of the measurement object. The image information is thus only superimposed on the display of the display device when a measurement process has actually been initiated. Otherwise, the display would remain disabled so that the user is not distracted by the display. In addition, this also saves the energy resources of the display device.

In a typical embodiment, the measuring device is designed as an oscilloscope, RF measuring device, spectroanalyzer, network analyzer, signal generator and / or direction finder. In addition, of course, other advantageous applications of the present invention would be conceivable. Especially for these applications, it is advantageous if the test engineer is not distracted by a measurement.

The above embodiments and developments can, if appropriate, combine with each other as desired. Further possible refinements, developments and implementations of the invention also include combinations, not explicitly mentioned, of features of the invention described above or below with regard to the exemplary embodiments. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

The communication interface 14 is with a display control device 16 coupled, which in turn with a display 15 is coupled. The display control device 16 is used to control the function of the display device 10 and is designed in such a way as to display the measurement data recorded via the communication interface and / or other optical information - if necessary in a correspondingly processed form - on the display 15 display.

The display control device 16 forms a mini-computer system within the electronic glasses 11 and may be formed, for example, as a microcontroller, microcomputer, digital signal processor, microprocessor and the like. Also conceivable would be a relatively simple programmable control logic in the form of an FPGA, PLD or similar circuit. It would also be conceivable that the intelligence of the display control device 16 at least partially not within the eyeglass frame 13 is embedded, but z. B. as an external control device wirelessly or hardwired, with the electronic glasses 11 is communicatively connected.

the display 15 is at least one of the lenses 13 assigned. Displaying the image information using the display 15 can be done in any way, for example by means of a head-up display function, a screen, a monitor or the like. the display 15 can be designed in various ways: For example, a so-called head-up display 15 be present, which, for example, on the side glasses frame 12 having existing imaging unit which emits a light beam in the direction of an optical module, for example a prism, so as to project the light beam onto a projection surface. The imaging unit creates an image. The corresponding optics module with collimator and deflection directs the image onto the projection surface. This projection screen is illuminated by a translucent, opaque lens 13 educated. In this way, the user is able to display the mirrored image information of the imaging unit on the spectacle lens acting as a projection surface 13 to recognize and at the same time perceive the real world behind it.

In addition, other embodiments for the display would be 15 conceivable. For example, one or both lenses could 13 even as a display 15 For example, they may comprise a transparent or semitransparent matrix display, for example. Such a transparent or semitransparent matrix display can be, for example be designed as an electroluminescent display or liquid crystal display, such as LCD screen, which is driven via one or more waveguides. Alternatively or additionally, a laser or an LED light source and a scanning system could also be used to project a raster display directly onto the retina of at least one user's eye. These are just a few alternative ways to have a display 15 for an electronic glasses 11 to realize a virtual reality.

The electrical power supply of the electronic glasses 11 takes place for. B. over in the spectacle frame 13 embedded battery or button cells 17 , It is particularly advantageous if these button cells 17 are rechargeable, for example, inductively rechargeable.

2 shows a perspective view of a second preferred embodiment of a display device according to the invention.

The glasses frame 12 is composed here of two side arms 20 . 21 as well as two lens frames 22 . 23 , each receiving a spectacle lens 13 serve. These frame elements 20 - 23 of the spectacle frame 12 are configured to the electronic glasses 11 Position and fix the user's nose and ears on the user's face. Each of the frame elements 20 - 23 of the eyeglass frame 12 may be formed of a solid structure such as plastic and / or metal, although other materials would be conceivable.

The corresponding spectacle lenses 13 may be of any material which is at least partially transparent and preferably completely transparent. Also, the glasses have to 13 not necessarily be made of glass, but can z. B. also be made of plastic (Plexiglas). The material of the lenses 13 must be able to display a projected image or a graphic, while the user still through these lenses 13 can see through. By combining these two properties of the lenses 13 It is possible to use a so-called augmented reality or head-up display function for the electronic glasses 11 when, for example, the projected image or graphic is a real image that a user through the lenses 13 perceives, superimposed.

The video camera 24 is in the front area of the side arm 20 so positioned to one in front of the electronic glasses 11 to capture existing area.

Finally, at least one key is used as an input device 25 also on the same branch 20 intended. Instead of a trained as a key or keyboard input device 25 would also be possible to use a touchpad. For a touchpad, it would be advantageous if the side arm 20 is formed flat.

The speaker 26 is in the material of the sidearm 20 embedded. About the speaker 26 appropriate acoustic signals, such as measurement-relevant information can be output.

The sensor 29 is in the example shown on the (in the direction of view) left sidearm 21 of the eyeglass frame 12 provided and preferably also in the frame element 21 embedded. The sensor 29 For example, it may be an acceleration sensor, a motion sensor, or the like.

3 shows a block diagram for a measuring arrangement according to the invention.

The with reference numerals 30 designated measuring arrangement 30 includes a meter 31 , a probe 32 and a display device according to the invention 10 as it is, for example, above based on the 1 and 2 was explained in more detail.

The probe 32 is here via an electrical connection line 33 with the meter 31 connected. Such probes 32 are in different manner known so that their structure and operation will be discussed below only briefly. probes 32 are commonly used to pick up electromagnetic signals. The recorded electromagnetic signals, for example current signals or voltage signals, are transmitted via the connecting line 33 to a connected meter 31 , in the example shown, a digital oscilloscope, forwarded and there via the display device 34 shown. Two or more probes 32 are used, for example, to pick up a differential signal on the measurement object.

The in 3 shown probe 32 includes a measuring tip 39 , an optical display element 40 , an actuator 41 , for example in the form of a button or a push button, and a probe camera 42 ,

The measuring tip 39 is required to a quiet, fixed placement of the probe 32 on a test object, the so-called Device Under Test (DUT) to ensure.

The display element 40 , which may be formed for example in the form of an RGB LED, the operating state of the probe 32 or a measurement process 10 optically signaled.

By means of the actuating element 41 For example, the user may initiate a measurement process.

Using the probe camera 42 images of the object to be measured or similar things can be recorded.

The electronic measuring device 31 be in the embodiment shown the 3 for example, an oscilloscope. The measuring device 31 comprises an optical display device 34 , various sockets 35 , which act as input / output interface, as well as various buttons and knobs 35 as input device 35 act.

The measuring device 31 further comprises a communication interface 37 which is formed in the embodiment shown as a wireless WLAN interface. Via this communication interface 37 can the meter 31 via a wireless communication link 38 with the display device 10 enter into a communicative connection.

In addition to a wireless communication interface 37 between meter 31 and electronic glasses 11 would also be possible to provide a connection cable here. However, this connection cable would again affect the freedom of movement of the user during the measuring process, so that advantageously a wireless communication interface 38 is preferred.

After a user is frequently unable to acquire a received electromagnetic signal on the display device during a measurement process 34 of the measuring device 31 to observe, for example, because his own arms affect the view, the meter 31 is too far away, the measurement does not allow a digression of the look, etc., according to the invention is a portable, visual display device 10 in the form of electronic glasses. This display device 10 For example, a user, such as a measurement test engineer, may use conventional glasses. The spectacles according to the invention 11 has in contrast to conventional eyewear the particular advantage that the user in addition to the real environment in addition to the z. B. on the display device 34 of the measuring device 31 displayed image information in the field of view of the electronic glasses 11 looks faded in. It would also be conceivable that other image information or even only parts of the displayed image on the electronic glasses 11 are displayed.

The function of the measurement order according to the invention will be described below 30 and in particular the display device according to the invention 10 based on 1 to 3 explained in more detail: on the probe 32 is carried out in a conventional manner testing or testing of a measurement object, not shown here. The over the probe 32 Recorded signals can via the display device 34 of the measuring device 31 are displayed. In addition, this image information can also be transmitted via the wireless communication interface 37 to the electronic glasses 11 be transmitted. The electronic glasses 11 takes over their communication interface 14 this image information and passes it to the display control device 16 further.

The display control device 16 prepares the captured image information as needed and controls the display 15 accordingly. The recorded image information will then be shown on the display 15 , completely or only partially, so that the user sees this image information displayed, but the field of view is not completely shadowed by the displayed image information. The user thus perceives the real world in addition to the displayed image information.

Via the communication interface 37 can be in addition to the image information and tax information on the glasses 11 transfer. For example, it would be conceivable that the electronic glasses 11 over the meter 31 activated or deactivated becomes. It would be conceivable, for example, that the electronic glasses 11 is activated only when, for example, the probe 32 starts a measuring process, for example when the measuring tip 39 contacted the measurement object.

The function of electronic glasses 11 may additionally or alternatively also via corresponding input devices which on the electronic glasses 11 are attached done. These input devices can, for example, in haptic form as a button or touchpad 25 or touch glass z. B. as a video camera 24 or sensor 29 will be realized.

For example, it would be conceivable that the video camera 24 For example, it is equipped with a gesture recognition function to detect a gesture of a user and assign a control function to this detected gesture. This gesture recognition feature can also be used in the video camera 24 coupled display controller 16 be implemented.

Additionally or alternatively, the sensor 29 be used as input and control device. For example, it would be conceivable that the sensor 29 contains an acceleration sensor in the form of a gyrator, which derives a control information from a head movement of the user.

An input device may also be via the microphone, for example 27 in conjunction with a speech recognition.

Instead of controlling the electronic glasses 11 via appropriate input devices, which directly to the electronic glasses 11 The function of the glasses can also be arranged via the measuring device 31 or the probe 32 to be controlled. For example, it would be conceivable that the function of electronic glasses 11 via one on the probe 32 attached button 41 is controlled. It is particularly advantageous if this button 41 on the probe 32 is programmable. In this case, a user could program as needed, what information he had on the electronic goggles 11 want to have displayed and in what form.

Although the present invention has been described above with reference to preferred embodiments, it is not limited thereto, but modifiable in many ways.
