Abstract

The invention discloses a method and an information inputting device in the form of a remote optical wireless pointer which does not require rechargeable batteries and the size of which is comparable with a thimble. Said invention makes it possible to easily and rapidly inputting information without using a keyboard and a mouse and to carrying out biometric identification according to a signature without making the mark of said signature. The inventive method involves placing a chain, consisting of infrared light-emitting diodes and photodiodes, along the perimeter of the screen of an information outputting device. The light-emitting diodes are connected to a power supply, and the photodiodes are connected to an ADC. At least four corner reflectors are mounted on the pointer in such a way that the faces of the reflectors are positioned in parallel to each other at a small distance therebetween. When the corner reflectors of the pointer are oriented towards the screen, the infrared radiation of the light-emitting diodes comes to the surface of the reflectors and comes back again. The photodiodes will capture the reflected radiation in such a way that it is nonuniformly distributed amongst the reflectors. Four photodiode regions with the greatest possible differential in the photo currents are generated, which photo currents represent the intersection of two imaginary plains, passing the clearances between two reflectors, with the perimeter of the screen along which the above-mentioned chain is extended. The intersection of two perpendicular lines passing through the four photodiode regions having the greatest possible differential, according to the amount of the received radiation, will provide the co-ordinates of the point at which the pointer is directed.

Description

The way to enter information using a remote pointer, a complex of a remote pointer that implements it and a way to identify a user with their help.

Description.

The invention relates to the optoelectronic industry, and in particular to a method and device for inputting information and a method for biometric identification based on them.

There are various methods and devices for remote input of information in the form of so-called presenters and markers. With their help, an alternative input of information into a personal computer is realized through the usual movements of the hand. A known method of biometric identification by user signature using various digitizers, consisting usually of a stylus and a special tablet that can read the movement of the stylus.

The disadvantage of presenters and markers is the presence of expensive electronics and the need for regular recharging of the built-in battery. The disadvantage of biometric identification by signature is the need for special equipment (digitizer), which has a considerable size. In addition, when entering a signature using a digitizer, signature traces remain on the surface that an attacker could take advantage of

The objective of the present invention is to develop a method and device for entering information in the form of a remote pointer, in which there is no electronics, and which, accordingly, requires neither wires nor charging batteries, and the size of the device will be comparable to a thimble, making it possible to more convenient and quick input without keyboard and mouse. In addition, with the help of this device, a method of biometric identification by signature is implemented, which does not require additional devices and leaves no trace of the signature.

This task is achieved by the fact that along the perimeter of the screen 1 (Fig. 1) of the information output device, a computer, a television, a projector screen, a garland 2 is placed, consisting of LEDs and photodiodes. The LEDs are connected to a power source, and the photodiodes are connected to an analog-to-digital converter 3. In order for the LEDs to not cause unnecessary interference to the user in the visible spectrum, it is necessary

SUBSTITUTE SHEET (RULE 26) ^~ use LEDs operating in the infrared range. Accordingly, photodiodes capture radiation in the same infrared range. And on the most remote pointer set corner reflectors 4 (Fig. 2). At least four pieces, plates parallel to each other at a small distance. The reflective surface of the corner reflectors is made of a material capable of effectively reflecting infrared light. If the remote pointer is directed by the corner reflectors 4 (Fig. 3, view from the screen side) towards the screen, then the infrared radiation from the LEDs will fall on the surface of the corner reflectors and come back. The photodiodes will catch the reflected radiation, but since there is a small gap between the corner reflectors, the reflected radiation will be distributed unevenly across the photodiodes. There will be four sections of photodiodes 5 with a maximum difference in the amount of received radiation. These sections are the intersection of two imaginary planes 6, passing through the gaps between the corner reflectors, with the perimeter of the screen along which the garland 2 with LEDs and photodiodes is stretched. And since imaginary planes intersect mutually perpendicularly, the intersection of two perpendicular lines passing through four sections of photodiodes with a maximum difference in the amount of received radiation will give the coordinates of point 7, to which the remote pointer is directed.

Before a detailed description of the invention, we explain the terminology used.

Under the corner reflector refers to a device in the form of a trihedral or dihedral angle with mutually perpendicular reflecting planes. Radiation entering the corner reflector from a trihedral angle is reflected in the strictly opposite direction. If radiation enters the corner reflector from a dihedral angle in a plane perpendicular to the surfaces of this corner reflector, the radiation will also be reflected in the strictly opposite direction.

A filter means a device that changes the spectral composition and energy of the light incident on it. Typically, a light filter is a glass with an admixture of certain salts, films of plastics containing organic dyes. Depending on the chemical composition, the filter passes only a certain frequency range of the radiation incident on it, absorbing the rest.

A garland of LEDs and photodiodes refers to a line of LEDs arranged one after another, connected via an electronic board to a power source and a line of photodiodes located one after another and connected to a SUBSTITUTE SHEET (RULE 26) analog to digital converter. Both lines of LEDs 8 (Fig. 4, side view) and photodiodes 9 are placed next to each other, but the photodiodes protect against direct radiation from the LEDs. For protection, lightproof partitions 10 can be used. In this case, the LEDs and photodiodes are directed in the same direction. Around each LED 8 (Fig. 4, a top view) several photodiodes 9 can be placed. The distance between adjacent LEDs 8 should approximately correspond to the distance between the faces of the corner reflectors 4 (Fig. 2). And the distance between adjacent photodiodes 9 (Fig. 4) is taken as the step of the scale when calculating the coordinates.

The method of entering information using a remote pointer equipped with corner reflectors 4 (Fig. 3), is implemented as follows. Alternately turn on the LEDs located on the garland 2. Moreover, the LED flashes can be additionally modulated. The infrared light emitted by the on LED is incident on one of the four corner reflectors 4 and then the light is reflected strictly in the opposite direction and is fixed by photodiodes located near the working LED. Moreover, depending on what angle the bisector of the corner reflector is located with respect to an imaginary line connecting the top of the corner reflector from the inside of the reflector and the LED, the magnitude of the reflected signal depends. The maximum magnitude of reflection occurs in 2 cases. The first case arises when the imaginary line coincides with the bisector of the angular reflector, and when deviating from the bisector, the reflection value gradually decreases. The second case arises when one of the faces of the corner reflector is almost parallel to an imaginary line. In this case, the light is reflected back from the entire surface of the other two faces. But it is enough to rotate the corner reflectors a fraction of a degree, so that an imaginary plane 6 passing between adjacent faces of the corner reflectors 4 passes through the LED and the rays emitted from the LED cannot be reflected in the opposite direction. In this case, the reflection value will be minimal. This difference is taken as the basis for the method of determining the direction of the pointer. Since the LEDs will turn on and off immediately one after another, then the photodiodes receiving the maximum and minimum reflected signal will be nearby, and, in this case, the same photodiode can turn on the maximum photocurrent when one LED is turned on, and when the adjacent LED turns on, give out minimum or even zero photocurrent value. But only in the case, as was said above, if an imaginary SUBSTITUTE SHEET (RULE 26) the plane passing between adjacent faces of the corner reflectors passes through section 5, on which these photodiodes and an LED are located, upon emission of which this section arose. There can be no more than four such sections 5 on the entire perimeter of garland 2. In other places of the garland, the difference in the magnitude of the generated photocurrents by photodiodes will change smoothly. In the analog-to-digital converter 3 (Fig. 1), it is determined which LEDs or photodiodes give the maximum difference in the magnitude of the generated photocurrents, and they determine the coordinates of sections 5 on all sides of the garland perimeter 2. The coordinates are determined either by the serial number of the LED on the perimeter side , when emitting which a section 5 has arisen, or according to the serial number of the photodiode on the perimeter side, which produces the greatest difference in the magnitude of the photocurrents when alternately emitting adjacent LEDs. Further, it is easy to calculate the coordinates of point 7, knowing the coordinates of sections 5, using trigonometric functions. This will require minimal computing resources. Moreover, you can save in the computer memory all possible combinations of coordinates of sections 5 and the coordinates of point 7 corresponding to these combinations. Then the calculation of the coordinates of point 7 will be almost instantaneous, and you can use the simplest RISC processor as a processor.

If four dihedral reflectors 11 (Fig. 5) are used as corner reflectors, which are mutually perpendicular to each other, then sections of photodiodes with a maximum difference in the magnitude of photocurrents will appear in those places of the garland through which imaginary planes passing through the edges of dihedral reflectors strictly perpendicular to their reflective surfaces. This is due to the fact that only in these planes the light emitted by the LEDs, reflected from the dihedral corner reflector, will return strictly in the opposite direction. Dihedral corner reflectors can also be made of a transparent material in the form of a triangular prism, provided that the lateral triangular faces are blackened in order to exclude internal reflection from these faces. It is advisable to use both types of corner reflectors on different distance indicators while using both.

To give the remote pointer additional functions, it may contain an additional control element made in the form of a shutter 12 (Fig. B) located on the axis of rotation 13 and set in motion by the user using external controls. Damper 12 made of

SUBSTITUTE SHEET (RULE 26) opaque material, when turning it is able to pass through a slit 14 made on one of the faces of the corner reflector 4. Accordingly, the turned shutter 12 will block the reflective surface of the corner reflector, and therefore, the light incident at that time on the corner reflector will practically cease to be reflected in reverse direction. If the shutter 12 (Fig. 7) is installed only on one of the four corner reflectors 4, then putting it into action, i.e. blocking the edge of the corner reflector, you can change the characteristic of the photocurrents generated by the photodiodes on the length of the garland perimeter, to which this corner reflector is directed. In this segment of the garland perimeter, limited by two adjacent sections 5 (Fig. 3), photocurrents will be generated with a minimum value. While on three other segments of the perimeter of the garland located between other sections 5, photocurrents will be generated much more intensively and with relatively equal differences in magnitude. This gives the opportunity to determine that the shutter 12 (Fig. 7) is activated, i.e. blocked one of the four corner reflectors 4. This fact can be used to control the cursor: if on all four sections of the perimeter the photodiodes generate photocurrents with relatively equal differences in the magnitude of the photocurrents, then the point on the screen can be displayed as a cursor, and if three segments of the perimeter of the photodiodes generate photocurrents with relatively equal differences in the magnitude of the photocurrents, and on the fourth segment of the perimeter of the photodiodes generate a minimum value in the magnitude of the photocurrents, a point on the screen can be displayed pour in the form of a pen, when moving which on the screen its path is displayed. Act on the shutter 12 can be different. For example, by pressing a finger on the shutter 12 located on the remote pointer 15 which will set the shutter in motion and block the reflective surface of one of the corner reflectors 4. Or, you can install the rod 16 between the corner reflectors 4 and bring the tip of the rod in front. You can use the rod on the shutter by means of a small lever 17, coaxially fixed to the shutter 12. In this embodiment, the remote pointer is conveniently used as a marker. It is enough to touch the screen with the pointer so that the rod goes inside, presses on the lever, which will deflect the shutter, which, in turn, passing through the slot in the corner reflector, will block the reflective surface. A change in the magnitude of the reflected signals at one of the segments of the perimeter will be recorded by an analog-to-digital converter, the converted information will go to the computer, and that will automatically turn the cursor into a pen. A SUBSTITUTE SHEET (RULE 26) you can change the thickness of the line left by such a pen by turning the remote pointer around its longitudinal axis, since this angle with respect to the perimeter is easy to calculate.

The method for determining the direction of the remote pointer does not allow to determine the coordinates of the pointer itself, but this may be necessary to expand the functions of the remote pointer. To do this, you can install additional scanners on the outer edges of the screen by turning them into the space in front of the screen. Scanners will record the proximity of the remote pointer to the surface of the screen. Such a scanner is an LED 8 (Fig. 8) surrounded by a photodiode array 18. A focusing lens 19 is located above the photodiode array itself. Due to this design, the light emitted by the LED 8 will be reflected from the corner reflector 4 (Fig. 7) mounted on the remote pointer 15, will return back and focus with the lens 19 (Fig. 8) in the form of a speck on the surface of the photodiode array 18. The photodiode array 18 will provide information on the relative coordinates of this speck, from which it will be possible to judge how close the distance is The ion pointer is located at the surface of the screen. It is supposed to use this information as follows: a certain threshold is set for approaching the surface of the screen of the remote pointer, for example 10 cm, and in the case when the remote pointer goes beyond this threshold, i.e. the distance becomes less than 10 cm, they will issue a command similar to clicking the left mouse button. Thus, if you move the remote pointer towards the screen on the visual object on the screen, the function of capturing the object will work, and then moving the pointer along the surface of the screen, you can drag the object from one place on the screen to another. Instead of scanners, you can use an additional row of photodiodes in the garland, each of which is directed into the space directly in front of the screen, and in addition it is advisable to install a visor above these photodiodes that limits the size of the space viewed by the photodiodes.

And you can implement the function corresponding to double-clicking the left mouse button if you program the following events: simultaneous approach of the remote pointer to the surface of the screen and its rotation around its longitudinal axis. To implement the function corresponding to the right-click of the mouse, you can program it by pressing the shutter 12.

In order to pick up reflected light from a remote pointer in any position of the pointer in space, 4 SUBSTITUTE SHEET can be installed on it (RULE 26) additional corner reflectors 20 (Fig. 9). All 8 corner reflectors are installed so that the adjacent faces of any two corner reflectors are strictly parallel to each other. The adjacent faces of the corner reflectors 4 and 20 are mounted close to each other.

It is easy enough to make a fountain pen from the remote pointer 15 (Fig. 9), if the rod 16 is made writable. In order to be able to enter handwritten information when using the remote pointer 15 as a pen, it is enough to install a garland with LEDs and photodiodes on the tablet 21 (Fig.

10) on which the paper will be. And so that the user's hand does not block the scanned space, the garland 2 must be installed not in the form of a rectangle, but in two rows, as shown in FIG. 10. The principle of entering information remains the same: on the garland 2 there will be four sections with a maximum difference in the photocurrents and, at their intersection, you can set the point on the tablet where the remote pointer rod is directed. It is clear that the role of the tablet 21 can play the surface of a conventional table. In this case, the remote pointer 15 can be made in the form of a computer mouse. And to enter additional information, it is proposed to use the following mechanisms, also based on the idea of reflecting light from corner reflectors. If button control is required on the remote device, then four corner reflectors 4 (Fig.

11) are arranged around the axis 13, so that the adjacent faces of the corner reflectors 4 are strictly parallel to each other and are at some distance from each other. Slots 14 are made in two corner reflectors located on opposite sides. And a butterfly valve 12 is mounted on the axis 13. The damper 12 rotates on the axis 13 under the influence of the key 22 using a mechanism 23 that converts the translational movement of the key into the rotational movement of the damper 12. When the button is pressed, the damper 12 will turn, enter the slots 14 and overlap the lower edge of the two corner reflectors. As a result of this, the two corner reflectors, when pressing the key 22, will practically cease to reflect light in the opposite direction. You can observe this phenomenon using scanners (Fig. 8) installed on opposite edges of the screen. Thanks to the focusing lens 19, when illuminating the corner reflectors with LEDs 8, up to 4 different spots will be fixed on the photodiode arrays of 18 scanners, and when you press the button, the number of spots will be halved.

In addition to the buttons, on the remote device can be installed wheel SUBSTITUTE SHEET (RULE 26) scroll. The rotation of the scroll wheel, equipped with a ratchet mechanism, can be transmitted to the same four corner reflectors, if you put them on the side surface of the disk. Thus, by rotating the scroll wheel, angular reflectors can be made to rotate about a common axis. It is easy to fix their rotation on the photodiode arrays of scanners, like the movement of spots in a circle.

Such a remote device with two buttons 24 (Fig. 12) and a scroll wheel 25 can be made in the form of a tube worn on the index or middle finger of the hand. Two sets of reflectors are placed on this tube, each of which consists of four corner reflectors 4. Press the buttons 24 and rotate the scroll wheel 25 conveniently with the thumb. If you put the tube on the middle finger of your hand, then you can put on the index finger a remote pointer 15, made in the form of a thimble, on the end of which four corner reflectors 4 are placed. Accordingly, scanners will be used to obtain information from the buttons 24 and the scroll wheel 25 (Fig. 8), and to obtain information about the direction of the remote pointer 15 will be used garland 2 (Fig. 1). At the same time, in order to distinguish between signals reflected from the corner reflectors 4 (Fig. 12) on the tube and on the remote pointer on the surface of the corner reflectors, as well as on the photodiodes, it is necessary to install different filters 26 and 27. On the photodiodes of the garland these will be filters, similar to the filters of the remote indicator, and on the photodiode matrix of the scanner there will be filters similar to the filters of the tube. Using a handset with buttons and a scroll wheel and a remote pointer, clad on fingers, you can completely imitate a computer mouse. Using the remote pointer, the user controls the cursor movement, and using the buttons and scroll wheel on the handset, actions similar to those of the buttons and the scroll wheel of a computer mouse are performed. At the same time, the remote pointer can also be used to enter text through a virtual keyboard that is displayed on the screen and as a presenter. And due to the absence of electronics and batteries in them, both devices are small and can be used as attachments to a conventional television remote control to give it additional functions, provided that the television receiver itself is equipped with a daisy chain, scanners and is connected to a computing device, which in turn can be connected to the Internet.

The resulting device for entering information is conveniently used to identify the user by his signature. But this is not about the user's signature, SUBSTITUTE SHEET (RULE 26) which he leaves on paper, and about the signature, which the user can reproduce without touching any surface. By picking up the remote pointer 15 (Fig. 9) or putting it on the index finger (Fig. 12) and pointing it towards the screen 1 (Fig. 1) with a garland 2, the user can reproduce his signature by making movements with the remote pointer in the air, as describing your signature. The resulting drawing will correspond to the enlarged handwritten signature of the user, as if he reproduced it on paper. At the same time, there are no physical traces of the signature anywhere. This method of biometric identification compares favorably with password identification in that the user always remembers his signature and you can accurately reproduce it even after a long period of time. At the same time, those who have seen and know the user's signature will not be able to copy the movements with the remote pointer to reproduce the user's signature, unlike the password. From the other methods of biometric identification, the proposed method compares favorably with the fact that without the desire of the user it is impossible to identify him, for example, when the user is in an unconscious state, which can be done with fingerprint identification.

To identify a user by signature using a remote pointer, the user will first be asked to reproduce his signature several times. Entered information containing data on the dynamics and trajectory of the point on the screen, to which the user directs the remote pointer 15 and which characterizes the user-entered picture of his signature, displayed on the screen in the form of a point trajectory, is copied to the medium using the program responsible for identifying user. And in the process of user identification, they will receive data on the dynamics of movement and the trajectory of a point on the screen, entered by the user using the remote pointer 15 and compare them with his identification data previously recorded on the medium. In case of their similarity, taking into account possible errors in predetermined parameters and limits, the user will be identified. Since often a graphic signature of people consists of several parts, the signature does not look like one continuous line, but as several intertwined individual lines. In this case, when playing back his signature using the remote pointer 15, the user can use additional signals supplied either by means of the shutter 12 (Fig. 9) or by using the button 24 (Fig. 12), which allow you to put the cursor in pen mode and

SUBSTITUTE SHEET (RULE 26) back, so that the signature drawing displayed on the screen fully matches the handwritten signature. These signals are also included in the user identification.

The user can be identified using the remote pointer 15 not only by his signature, but also by his handwriting. In this case, the user is first offered to play all possible characters and combinations of these characters with each other using the remote pointer. And in the process of identification, a random combination of characters is generated and the user is prompted to enter them using the remote pointer. This method of user identification is especially convenient when a user accesses resources over a network, for example, over the Internet. In this case, the user credentials are previously stored on the server for subsequent identification when requesting access to server resources from the client terminal.

It is convenient to combine the biometric identification of a user by signature using a remote pointer with recognition of the remote pointer itself, for example, using the automatic radio frequency identification (RPID) method. In this case, the remote pointer 15 is additionally equipped with a transponder (RFID tag), and a reader is placed near the screen that can read data from the transponder at a distance of several hundred centimeters. Such a combination will allow one-time identification of the user during the session by his signature using his remote pointer, and when the user moves away from the screen, taking with him his remote pointer - automatically block access to user resources. As soon as the user approaches the screen again, the reader identifies the transponder located in the user's remote pointer and opens access to its resources. In addition, the recognition of a remote pointer using a transponder can be used to automatically select a user ID in an electronic database to save the user from entering a login while accessing computer resources.

In general, the remote pointer can be made of polymeric materials, and corner reflectors made of metal coated with a reflective layer. Optics of a garland and scanners are made on the basis of semiconductor LEDs, photodiodes, CCD arrays. An analog-to-digital converter is manufactured on the existing element base with the ability to connect to a personal computer, for example, via USB.
