Arrangement of a table and a Bildprojizierenden device and control methods

The invention relates to an arrangement of a table and a

Image projecting device according to independent claim 1, the use of such an arrangement in a conference system or

Video conferencing system according to claim 14 and a method for controlling at least one electrical and / or electronic device by such an arrangement according to the preamble of the independent one

Patent claim 1 5.

Especially in meeting rooms, it is known, bildprojizierende

Devices, in particular projectors to install in the ceiling, the projectors image data on a projection screen, which often mounted on a building wall itself or on a wall

Projection screen are formed.

It is also known in the equipment of conference or video conference rooms that on the present in the conference or video conference room table or table arrangement of the table top protruding devices, especially screens, laptops, etc. or embedded in the table

Touch panels or other control elements are provided. such

Arrangements of devices on tables are visually extremely disturbing, since they interrupt the continuity or the planar design of the table top or table surface or dissolve.

Especially with standing arranged devices, such as screens occurs in video conferencing arrangements additionally the problem that the switched over the videoconference party can not recognize the image content displayed on the screen, since the display area of the Screen can not be captured by the camera of the videoconferencing system. Thus, the connected party can not recognize what is displayed on the screen of his switched party. As a result, there is often uncertainty among the call partners as to whether the connected caller receives the desired picture content.

In addition, the non-visible, standing on the table

arranged screens a separating barrier between the

Interlocutors, as these are arranged wall-like in the receiving area of the camera between the caller and the receiving camera. Thus, such arrangements of screens on the conference table are a hindrance to trusting and successful conference or videoconferencing. Proceeding from this, it is an object of the invention to provide an arrangement of a table and a bildprojizierenden device that allows for an open and transparent video conferencing, on the other hand, a control of the video conferencing system or other provided in space electronic or electrical units.

The object is achieved on the basis of the preamble of independent claim 1 by its characterizing features. The use of such an arrangement in conference and / or video conferencing rooms is

A method for controlling at least one electrical and / or electronic device by a

Arrangement according to the invention is the subject of patent claim 15.

The arrangement according to the invention comprises at least one table with a table top and at least one arranged above the table

Bildprojizierender device is characterized in that the

Projection is at least formed by a portion of the top of the table top and that the table at least one touch-sensitive Sensor unit, by which a touch-sensitive user interface is formed on the surface of the table top, wherein at least a partial surface of the user interface is within the projection surface. The inventive construction of the arrangement, it is possible on the

Table surface, i. on the top of the tabletop display image data through projection and through the touch-sensitive user interface

Make control commands by touching in particular by touching the finger. As a result, in particular when using such

Arrangements in conference rooms or video conference rooms, in which a large table or more, a table arrangement forming tables are provided and on the seats in each case a bildprojizierende

Device or groups of seats is arranged in each case a bildprojizierende device, without the use of standing on the tables or protruding from these display units or monitors on the

Table surface even image data to be displayed. As a result, the optical continuity of the table is maintained and it creates an open-acting environment in the conference or video conference rooms, so that a trusting and successful conference or videoconferencing is possible.

In a preferred embodiment, the user interface lies completely within the projection surface. This ensures that can be displayed or projected by the projector on the user interface controls, in particular a control panel with multiple controls. When a user touches the user interface within such a control panel represented by the projector, such an input may be used to control

electrical or electronic devices of the conference facility or videoconferencing equipment room. Further preferably, the user interface forms a portion of the screen, i. the projection surface is made larger than the

User interface. As a result, despite displaying a control field, for example In the area of the user interface, the further free area of the projection surface can be used to display other image contents, for example presentations etc.

display. Furthermore, it is possible in the area of the user interface, for example, a keyboard or the like can be represented by the projector, so that, for example, a text input via the user interface is possible. In the further area of the projection area, which is not occupied by the user interface, a representation of the inputs can take place, for example, as a text line or the like. This is due to the inventive

Arrangement an input comparable to the inputs in tablet PCs possible. Particularly preferred are a congruent design of the projection surface and the user interface, i. the projection surface and the user interface have the same or substantially the same size and are congruent to each other. Thus, user inputs can be made by touching the user interface on the entire projection surface by the user, as a result of which on the table surface quasi the

Let user interfaces of a known from the prior art tablet PC map.

In a particularly preferred embodiment, the

touch-sensitive sensor unit not visible in the upper side

Integrated tabletop or arranged at the bottom of the table top. As a result, the surface of the tabletop is not interrupted even in the area of the touch-sensitive sensor unit and the table appears in the off state of the projector as a conventional table with a continuous, uninterrupted tabletop. Only after the projection of image data onto the projection surface and representation of a control field or control elements does the user recognize that inputs are possible via the arrangement.

In a particularly preferred embodiment, the

touch-sensitive sensor unit provided in a recess of the support material of the table top and is covered by a continuous cover layer. In this case, any cover layers can be used as cover layer non-conductive material, in particular veneers, Corian, glass, etc. are used. Preferred cover layer materials have a light surface and are matt. As a carrier material solid wood from all common types of wood, real wood fiber boards, plastic plates, Resopal plates, plates made of Corian, glass, acrylic glass, natural stone, artificial stone, etc. can be used. The integration of the touch-sensitive sensor unit gives the user again the impression that it is a conventional table, whereby the complete integration in the table also allows the externally protected recording of the touch-sensitive sensor inside the table.

Particularly preferably, the touch-sensitive sensor unit is a capacitive sensor unit. In such capacitive sensor units is a

Capacity change by touching the touch-sensitive

Sensor unit or the touch-sensitive user interface or by approaching the touch-sensitive sensor unit causes. These

Capacity change is localized and evaluated. Depending on the location of the touch or the movement of the touch on the

touch-sensitive user interface, a control of the electrical or electronic device or a change in the representation on the

Projection surface, for example, a zoom in or zoom out done. Capacitive sensor units are particularly suitable for operation by means of the finger, so that no special input pens or the like are necessary. The touch-sensitive sensor unit may in particular be multi-touch capable, i. be designed for detection and evaluation of multiple simultaneous touches of the touch-sensitive user interface at different locations. As a result, for example, a representation change, in particular a zoom in or a zoom out can be effected. The

touch-sensitive sensor unit represents a high-resolution unit with a resolution of 4096 x 4096 points. Particularly preferably, the touch-sensitive sensor unit is formed from two plate-shaped elements and a sensor layer arranged between these plate-shaped elements. The plate-shaped elements are in this case preferably glass plates, between which the sensor layer is laminated. Such a sensor unit constructed is insensitive and even has sufficient stability, so that it can be easily integrated into the table or placed under this table.

The image-projecting device is particularly preferably a projector, in particular an LED projector. Further preferably, the projector has an immediate start, i. the image reproduction takes place with high brightness within a few seconds, in particular less than five seconds. Furthermore, the projector preferably has an immediate stop, i. a cooling-down phase is not required and an associated re-ignition delay does not occur. Projectors with LEDs as light sources or projectors with a LED laser hybrid technology are characterized by a long service life of their lamps. For example, they have operating times or lifetimes in the range of 20,000 to 40,000 hours. They are therefore for continuous use in

Conference rooms suitable. Furthermore, preferably, projectors that use LEDs as bulbs, a low electrical power consumption.

As a result, even small amounts of waste heat, which can be easily dissipated, even when installing the projector within the ceiling or in

Lighting modules above the table. In the beam path of the projector may also be introduced a lens, so that at the table depending on the

Removal of the projector to the surface of the tabletop a defined

Projection range is shown in the range between 17 inches and 30 inches screen size, especially 18 inches, 20 inches, 22 inches, 24 inches, 26 inches, 27 inches and 28 inches. The brightness of the projector can be between 500 and 3000 lumens, whereby the extremely low projection area on the table for the projectors causes a high brightness of the image, so that a very high visibility of the projection image is ensured even with dark table surfaces. In a preferred exemplary embodiment, the image-projecting device is integrated in a lighting technology module which is arranged above the table, in particular in the region of the tabletop above the table. This allows a vertical projection of the light beam down a picture of the

Image data on the tabletop done. At least one lighting unit for illuminating the table surface and / or at least one document camera and / or at least one motion sensor is preferably provided in the lighting technology module in addition to the at least one image-projecting device.

By means of the document camera, for example, image content of the

Table top, for example, recorded documents lying on the table and during a conference the other conference participants in particular in the distance switched conference participants during a

Videoconferencing will be provided. The motion sensor may be used, for example, to control the projector, to switch the image data displayed by the projector, or the like.

Particularly preferably, the motion sensor is provided above the table, wherein the motion sensor is at least indirectly connected to the bildprojizierenden device, that by an output of a movement detection by the motion sensor signal a connection or disconnection of bildprojizierenden device or switching of the

image-projecting image data displayed on other image data to be displayed. The motion sensor thus provides an intuitive control device that can be controlled via gesture control, i. by movement of the body or parts of the body of the user, in particular, for example, the arm, can be operated.

In a particularly preferred embodiment, at least partially cover the detection range of the motion sensor and the projection surface. Particularly preferably, the detection range of the motion sensor lies completely within the projection surface. This will be for the user intuitively operated system, since exactly the area occupied by the projector with image data can also be used for gesture control of the system. In a particularly preferred embodiment are about a

large-area table or an arrangement of several tables on which or a large number of seats for conference participants are available, bildprojizierende devices arranged such that in each case between two seats a projection surface is arranged on the surface of the table top. Thus, two conference participants in each case located between them part of the surface of the tabletop image data, the data from a

Projector. Thereby, the use of a reduced number of image projecting devices is possible, so that the cost of the entire system can be reduced. Alternatively, all seats can be provided with a bildprojizierenden device.

Particularly preferably, use of the arrangement according to the invention takes place in a conference system or in a video conference system. Here are all seats or groups of seats at a conference table or a conference table arrangement above each with bildprojizierenden

Equipped so that every seat or group of

Seating is assigned to a projection screen by the respective

Conference participants is well visible. Through the image projecting

For example, devices may display image data of a presentation on the respective projection surfaces, i. Each image projecting device receives as input the same image data, so that each one

Conference participants directly in front of the presented image content

can perceive. As a result, a projection of the presentation data onto a central, large-area projection screen arranged in the room can be dispensed with. Especially with video conferencing, the arrangement according to the invention offers the decisive advantage that the participants in the videoconference, external On the other hand, the opposite party may at least partially recognize the image data being imaged by the image projecting device on the surface of the tabletop, so that in video conferencing, common questions such as "See the document?" or "What do you see?" are no longer necessary. This allows a much more open and trusting video conferencing.

The invention further relates to a method for controlling at least one electrical and / or electronic device by means of an arrangement as described above. The method is characterized in that image data are represented by the image-projecting device on a projection surface formed at least by a partial region of the surface of the table top, that an input on the sensor is provided by at least one user interaction with the touch-sensitive sensor unit

touch-sensitive user interface takes place and that the input causes a control of the electrical and / or electronic device. The arrangement according to the invention can thus not only be used to display the image content of a presentation or a video conference, but it can via the touch-sensitive user interface a

Control of electrical or electronic devices, such as computers, a conference or video conferencing system, of equipment of the room or building technology, such as lighting, shading or air conditioning done. In a preferred embodiment of the method is on the

Projection area at least one control shown. By touching the touch-sensitive user interface in the region of the control element, a signal is generated by the touch-sensitive sensor unit, which signal is evaluated by a control computer and converted into a control signal for an electrical or electronic device. The touch of the control can in this case, for example, the increase in the room temperature through the

Air conditioning or shutting down the shading effect. Particularly preferably, at least one field of control elements is displayed on the projection surface. About this field can be a variety of

Control commands or controlled inputs made by the user. Each control is in this case assigned a function, so that by touching the touch-sensitive sensor unit at the appropriate locations

Control inputs are generated.

In a particularly preferred embodiment, on the

Projection surface at least partially displayed image data, which are simultaneously displayed on other bildprojizierenden devices or projected by other bildprojizierende devices. This is accomplished by coupling the image projecting devices to each other via a video splitter or video router. So it is for example in one

Conference room that has a table or a table arrangement with a seat for a conference leader and several seats for a variety of

Conference participants, it is possible that the same image data are projected by the bildprojizierenden devices that are assigned to the conference participants, as by the conferencing associated image conferencing device. The conference leader can, for example, additionally be shown a control panel by the image-projecting device, by means of which he can input information to the conference system or

Video conferencing system. In a preferred embodiment, at least one interaction of a user with the touch-sensitive sensor unit or a motion sensor at least partially causes a change of the displayed image data. For example, in the field of touch-sensitive

User interface an input option, such as a keyboard or the like can be displayed, via which the user can make inputs that directly affect the image content represented by the bildprojizierende device. Further, by a motion sensor a Gesture control are enabled, so that, for example, by a rapid movement of the hand by the motion sensor monitored

Detection area switching the image content, on or off the projector, brightness changes, etc. are effected.

The term "essentially" in the context of the invention means deviations from respectively exact values by +/- 10%, preferably by +/- 5% and / or

Deviations in the form of changes that are insignificant for the function. Further developments, advantages and applications of the invention will become apparent from the following description of exemplary embodiments and from the figures. In this case, all described and / or illustrated features alone or in any combination are fundamentally the subject of the invention, regardless of their summary in the claims or their dependency. Also, the content of the claims is made an integral part of the description.

In Figure 1, an inventive arrangement of a table 1 with a table top 1.1 and arranged above the table 1 bildprojizierenden device, which is formed in the illustrated embodiment by a projector 2 is shown. Through this projector 2, a light beam 2a is emitted in such a way that image data is imaged by the projector 2 on a projection surface 3, which is formed by a partial region of the surface of the table top 1.1. The tabletop 1.1 in this case preferably has a matt, bright surface, so that the projected image is easy to recognize for the user. The projection of the image data onto the projection surface 3 forms the

Table top 1.1 one for the persons located at the table 1 persons

noticeable display area.

The table 1 also has at least one touch-sensitive sensor unit 4, by means of which a touch-sensitive user interface 5 is formed on the surface of the table top. In this case, at least a portion of the user interface 5 is within the projection surface 3. In the shown

Embodiment, the user interface 5 is completely within the projection surface 3 and is smaller than the projection surface 3 is formed. However, the user interface 5 can be large and congruent or substantially large and congruent with the projection surface 3.

In the exemplary embodiment shown, the projector 2 is integrated in a light technology module 6 arranged above the table 1. Alternatively, the projector 2 also be arranged in the ceiling of a room itself or in a mounted on the ceiling housing, in particular a sound-insulated housing. As indicated by the pyramidal light beam 2a of the projector 2, the projector 2 projects image data from above onto the surface of the table top 1.1, so that the persons seated at the table can perceive this image data on the table surface. This makes it possible to display image data without having to arrange monitors on the table or integrate them into the table. In Figure 2, the arrangement of the projector 2 is shown above the table top 1.1 in a side sectional view through the lighting module 6. The projector 2 is oriented such that the light beam 2a emitted by it initially run in the horizontal direction or in the substantially horizontal direction. Subsequently, the light beams are deflected by a mirror 2.2, so that they are projected down onto the table top 1.1. The illuminated by the projector 2 surface of the table top 1.1 here forms the projection surface 3. The projection surface 3 is preferably rectangular in shape and may have a size of conventional image display devices, in particular monitors, for example in the range of 17 inches to 30 inches. Furthermore, a lens 2.1 can be introduced into the beam path, preferably between the projector 2 and the mirror 2.2. By this lens 2.1, an adjustment of the beam path is effected such that the projection surface 3 has a desired size. The lens 2.1 can for example also be formed by a lens bundle. Alternatively, the projector 2 can also be arranged vertically in relation to the table top 1.1 in the vertical direction, so that the light beam 2a is already radiated perpendicularly or substantially perpendicular to the table top 1.1. As a result, the installation of a mirror 2.2 can be omitted for the deflection. FIG. 3 shows an arrangement of a projector 2 and a motion sensor 6.2 above the tabletop 1.1 and its schematic interconnection. The projector 2, which together with the motion sensor 6.2 in the ceiling, in a arranged on the ceiling housing or in a

Lighting module 6 may be provided projected image data on the mirror 2.2 deflected onto the projection surface 3. The motion sensor 6.2 preferably has a very narrow detection range 6.2a. The detection area 6.2a is defined, for example, by a respective detection angle of 15 ° to 20 ° in two mutually perpendicular spatial planes. Of the

Detection range of the motion sensor 6.2 overlaps in the area of the table top 1.1 at least partially with the projection surface 3. Preferably, the projection surface 3 and the detection range of the motion sensor 6.2 congruent or substantially congruent in the area of the surface of the table top 1.1.

The motion sensor 6.2 is connected via a control unit 6.2.1 with a

Control input of the projector 2 or a control input of a

Switching 7 connected. About the switching device 7 can between different, applied to the switching device 7

Video signals 7a, 7b, 7c are switched.

The motion sensor 6.2 or the control unit 6.2.1 assigned to it are designed in such a way that only fast or very fast movements from a control unit 6.2.1 assigned to the motion sensor 6.2 are converted into control signals for the projector 2. The control signals generated by the control unit 6.2.1 can in this case be supplied directly to the projector 2 and, for example, a switching on or off of the projector or a change in the light emitted by the projector 2 or the like. cause. Alternatively, the control signals generated by the control unit 6.2.1 of the switching device 7 can be supplied so that triggered by the control signals between the video signals 7a, 7b, 7c is switched. In particular, the

Switching device 7, a video switcher having, for example, a plurality of inputs for video or image signals, so depending on the control signal supplied by the control unit 6.2.1 one at the respective input of the switching device 7 applied video or image signal to the output switched through the switching device 7 and the projector 2 is provided for presentation. By means of the switching device 7, it is thus possible, for example, to represent a main image or a main video sequence in a user-controlled manner and to display the representation of, for example, a control surface or switching surface or a standby image or film in a user-controlled manner.

Figure 4 shows a section through the table top 1.1 of the table 1. The table top

1.1 is formed by a substrate 1.2, at the top, i. the side facing the user sitting in front of the table, a cover layer 1.3 is applied. The cover layer 1.3 can be formed for example by a veneer, a real wood layer, by a Corian layer or a layer of another, non-metallic material, for example plastic. Due to the cover layer 1.3, a continuous, uninterrupted surface of the table 1 is ensured at the top of the table top 1.1. In the carrier material

1.2, a recess 1.2.1 is introduced at the side facing the cover layer, the depth of which is adapted to a touch-sensitive sensor unit 4 to be introduced into the recess 1.2.1. Preferably, the depth of the recess 1.2.1 is equal to the height of the touch-sensitive

Sensor unit 4, so that after introducing the touch-sensitive sensor unit 4, the carrier material 1.2 facing away from the top
