Definitions
- the present invention relates to an interface assembly between a user and an electronic device comprising a control logic and a rectangular screen with a scan.
- Such a screen is scanned by a light zone which successively covers all the points of the screen according to a predetermined scanning cycle.
- Cathodic screens are by construction scanning screens since the image is created by the passage of a light beam on each point of the screen.
- the screens of different types also have a notion of scanning, but different. Indeed, for reasons related to the control electronics, the screen is refreshed point by point or zone by zone, but the visual effect is much less than for a CRT screen because a point of such screen type, as opposed to the point of a CRT screen, keeps a constant intensity between two refreshes. It is however possible to introduce a notion of scanning in the sense indicated above by modifying the characteristics of the cooling so that during a cooling cycle, a very light or very dark area of small size, called light spot in the continuation of this document, successively covers all the points on the screen.
- the invention applies in particular to remote controls for controlling the operation of a television or a video recorder. Controlling the operation of these devices by means of remote controls usually encountered is tedious since the command option windows must be successively displayed on the screen before a user can select one of the operating modes of the television or video recorder.
- the present invention aims to remedy the aforementioned drawbacks by providing an interface assembly which allows easy remote control of an electronic device by simple, effective and inexpensive means.
- an interface assembly of the type in question is essentially characterized in that the assembly comprises: - a control system (1) comprising:
- an illumination sensor D suitable for scanning the screen by the light spot and having a detection field which is limited to a reduced zone Z of the screen (3);
- a local clock (70) whose resolution and accuracy are compatible with those of a video signal of the means using information external to the screen (3) to synchronize the local clock
- the control system (1) of the interface device can also include: - a wide field illumination sensor (L) suitable for scanning the screen by the light spot and having - a detection field which includes all of the screen (3) under normal conditions of use of the control system (1) by a user. - means for detecting the appearance of the light spot in the detection field of the wide field illumination sensor (L) to produce a signal of predetermined logic level;
- synchronization of the local clock is meant the resetting of this clock with a precision of the order of a microsecond relative to the clock which served to generate the video signal, and therefore in particular to define the start times. image.
- a general purpose quartz typically has an accuracy, when its temperature varies moderately, of the order of 20 to 50 ppm (parts per million), ie 2 to 5 thousandths of a percent; it is generally only in professional equipment at a cost much higher than consumer equipment that there are oscillators whose guaranteed accuracy is, for example, 0.5 ppm (parts per million) and such precision is generally obtained with selected quartz and kept at constant temperature
- the duration of a line is 64 microseconds and the durations of an image are 20, 20 and 16, 7 milliseconds respectively.
- a transmission chain (4) from the electronic device (2) to the control system (1) makes it possible to synchronize the local clock (70) of the system (1).
- the different elements of this chain of transmission are as follows:
- a synchronization of the local clock (70) carried out in the control system (1) can be carried out at the local clock (70) proper by modifying its frequency, for example by means of a phase-locked loop, or at the microcontroller (60) by resetting counters time and updating the exact number of pulses from the local clock (70) which correspond to the effective duration of an image displayed on the screen (3)
- the transmission from the device (2) to the system (1) of information indicating the instants of start of image or of start of scanning of the images displayed on the screen (3) can be done in different ways.
- the simplest modality is a transmission in the form of pulses which indicate with an accuracy of the order of a micro second these instants or which have a sufficiently constant offset with these instants so that the resulting precision is also of the order of the microsecond.
- Such a pulse transmission requires a large bandwidth, of the order of megahertz.
- a widely used and low cost transmission channel for this type of transmission is infrared transmission.
- a wide bandwidth channel will be called a transmission channel, such as infrared, whose bandwidth allows the direct transmission of these pulses, and a narrow band transmission channel will be called any transmission channel whose band bandwidth does not allow this transmission.
- An example of a narrowband transmission channel is a radio frequency in the free-use bands (such as 27 or 72 or 433 Megahertz). Indeed, the bandwidth of a transmitter using these frequencies is limited by regulations to a few kilohertz, which prevents the transmission of the pulses described above. As By comparison, the bandwidth allocated to a terrestrial television channel, which must transmit a very rich signal, is of the order of 6 megahertz.
- protocols for managing local computer networks such as Ethernet can provide a large or very high average bandwidth to users, but do not guarantee the delivery time of each message sent, since a message can be sent several times successively. by its transmitter before being able to circulate on the network.
- Bluetooth The case of the management protocol for local micro-networks commonly known as "Bluetooth” illustrates certain concrete difficulties in transmitting synchronization pulses under satisfactory conditions and the practical uncertainties that may exist as to the possibility of considering certain transmission channels as or not. broadband channels.
- Bluetooth In this protocol for managing local micro-networks commonly called "Bluetooth”, there are mainly two modes of information transmission: (a) synchronous channels intended for the transmission of the voice and sampled at 64 kilobits per second (b) asynchronous channels of packet data transmissions with higher bandwidths but without particular guarantees of information transmission delay .
- the 64 kilobit synchronous channels of "Bluetooth” it would in principle be possible to use them in data transmission mode to transmit information from time to time with an accuracy of the order of a micro second, for example as follows: at the precise instant that one wishes to indicate, a particular code is transmitted, followed by a number indicating the time offset between the instant to be indicated on the one hand and the instant of sampling (at 64 kilobits, there is sampling every 16 microseconds).
- it is up to a communication protocol to verify that the communication of information went well, for example by using acknowledgments of receipt of messages and by checking that the total time for the round trip is less than a value defined in advance and of the order of a few microseconds.
- the optical pencil was used from the 1960s in a computer context to allow a user to indicate a position on a computer screen by moving on the surface of the screen (which was a scanning screen) a shaped device. pencil electrically connected to the image or video signal generation device.
- the pencil-shaped device contains a detector analogous in principle to the detector D of the present invention and sends when the light spot passes a pulse to the device for generating the image or the video signal.
- the image or video signal generation device has means for:
- Optical pistols are the use of this same principle in modern game consoles, replacing the pencil with a device such as a pistol which is kept at a distance from the screen on which the images generated by the console are displayed. games.
- the position information of the targeted area is available in explicit form and usable without any particular time constraint outside the image or video signal generation device.
- the image or video signal generation device can process the time or position information transmitted by the system (1) with a delay adapted to a man-machine interface, that is to say a few tenths of second, or about ten thousand times the processing time imposed in the context of the pencil or optical gun to the image or video signal generation device d) Communication between sensor D and the image or video signal generation device is particularly simple if one of the two channels (of the system
- the present invention is limited to the use of image synchronization signals, to the exclusion of line synchronization signals, which are 200 times (or more) more numerous, and which would therefore provide information 200 times (or more) more precise, but which in return have the disadvantage of requiring for their transmission an occupation 200 times (or more) greater of the transmission channel than for the transmission of image synchronization information

- the total duration of the visible part of a frame is approximately 18 milliseconds
- the total duration of a line is 64 microseconds
- the logical and arithmetic processing means calculate the position of the targeted zone Z on the screen from the time difference existing between on the one hand, the instant of the start of scanning of the image and on the other hand , the appearance of the logic signal corresponding to the illumination sensor D which corresponds to the passage of the light spot in front of the targeted zone Z

- FIG. 6 shows an alternative embodiment of the control system comprising two illumination sensors operating on the same principle as the sensor ( D).
- FIG. 7 is a schematic view with diagrams of the interface assembly according to the present invention comprising a control system with a two light sensors: the sensor (D) on the one hand and the field sensor wide (L) on the other.
- the interface assembly takes, for example, the form of: a remote control unit comprising all the elements of the remote control system (1) as well as the additional means making it possible to implement the “Receiver” function and the function “Local clock synchronization” of the transmission chain (4)
- the transmission of information from the system (1) to the device (2) can in particular be by using the conventional techniques of emission by infrared or by radio, or also by ultrasonic waves.
- the control system (1) can generate its time or position information in the form of a binary signal at 1,200 or 2,400 baud which modulates a carrier frequency of the order of 30 kilohertz which itself modulates an infrared signal emitted by a diode LED.
- the receiver included in (2) can be a standard infrared receiver for television remote controls which is adapted to an infrared signal modulated at a frequency of the order of 30 kilohertz, and which can restore the binary signal at 1,200 or 2,400 baud at a V24 serial interface the control logic of the device (2) can then read from the V24 serial interface the time or position information transmitted by the control system.
- high-level software means that is to say without direct contact with the characteristics of the hardware, are typically sufficient to process this position or time information, as well as the requests from the control device (1) relating to the display. specific images to be analyzed by the wide field illumination sensor (L)
- the transmission chain (4) from the device (2) to the system (1) can be carried out as follows when the video signal is accessible and the transmission of synchronization information from to the system (1) to the device (2) is carried out by a channel wide bandwidth such as infrared transmission: a)
- the extraction of the image synchronization signal can be carried out in the vast majority of cases by one of the following methods:
- VGA to TV conversion b) The generation of a pulse at the start of the image synchronization signal is carried out by conventional means. c) The infra-red transmission of this pulse with an accuracy of the order of a microsecond can be achieved by means of the emitting diode SFH421, the rise time and fall time of which are approximately 500 nanoseconds, controlled according to classic techniques.
- (1) can be achieved by means of the amplified photodiode OPT210 from Burr-Brown (registered trademark, website: http://www.burr-brown.com) in front of which is placed a filter allowing the infrared to pass but blocking the light visible, and followed by a high-pass filter, for example with a cut-off frequency of 150 kHz and 6 dB / octave attenuation, to eliminate the effects of artificial lighting, which typically provide light whose intensity is modulated at a frequency of 100 or 120 hertz according to the country and eliminate the signals whose frequency varies between 30 and 40 kilohertz emitted by the usual infrared remote controls.
- the signal supplied by 1OPT210 after filtering, low-pass filtering to eliminate the frequencies above the useful bandwidth of the signal and amplification is white noise to which the received pulses are superimposed
- a comparator such as the LM339 set to a threshold of 6 or 10 db above the observed noise level allows to generate a logic signal corresponding to the start of the reception of a synchronization pulse (the switching time of a comparator such as the LM339 with a strong input signal is typically of the order of half a microsecond); these same techniques can be used to make the wide field illumination sensor (L)
- the synchronization of the local clock (70) is carried out by the microcontroller (60) according to the following methods: the microcontroller (60) measures by means of the local clock (70) the time elapsed between two pulses corresponding to two successive beginnings of images
- Detection with a precision of the order of a micro second of the passage of the light spot in front of the sensor D can be achieved by means of the amplified photodiode OPT210 from Burr-Brown in front of which is arranged an optical assembly described later whose objective is to restrict the viewing angle of the sensor D, and followed by a high-pass filter, for example at cut-off frequency 10 kHz and 6 dB / octave attenuation, to eliminate the effects of artificial lighting, which typically provide light whose intensity is modulated at a frequency of 100 or 120 hertz depending on the country.
- the signal supplied by 1OPT210 after high pass filtering, low pass filtering to eliminate the frequencies above the useful bandwidth of the signal and amplification is a white noise to which the received pulses are superimposed
- a comparator such as the LM339 set to a threshold of
- the filtering and amplification functions can be performed for example by means of operational amplifiers whose gain X bandwidth product is greater than 10 megahertz.
- Signal amplification must have the highest possible bandwidth to provide a position calculated with good accuracy.
- Photodiodes have very fast response times, on the order of a microsecond. However, it will be necessary to limit the bandwidth of the amplifiers to the useful bandwidth of the signal, which is a few hundred kilohertz at most.
- the detection of the presence of the light spot in the capture field of the illumination sensor D is carried out by means of comparators supplied by the alternating signal supplied by the amplification stages, or by comparators supplied continuously by operational amplifiers. The output of each comparator is connected to an input pin of the microcontroller which makes it possible to measure the instants at which this pin goes from a high logic level to a low level or vice versa.
- Microelectronics use a local clock and internal time counters that are precise enough to measure time intervals with an accuracy of 0.5 or 1 microsecond. Their processing speed is sufficient to process in less than 64 microseconds (which is the scanning time of a television line) two interruptions corresponding for example to logic signals generated by pulses such as synchronization pulses or logic signals emitted by the sensor D or the wide field illumination sensor (L); it will be noted in this regard that it is not necessary that the sensor (D) and the wide field illumination sensor (L) are active simultaneously, and that therefore only the information of one of the two sensors must be processed at a given time.
- the microcontroller (60) is connected to the system user interface (1) allowing the user to indicate that the system must perform a position measurement of the zone Z.
- the transmission chain (4) from the device (2) to the system (1) does not include a broadband transmission channel such as an infrared transmission, but the system transmission channel (1 ) to the device (2) is a broadband transmission channel such as infrared transmission, it is still possible to reduce to the previous case and synchronize by means of pulses the local clock (70 ), for example as follows:
- the control system (1) periodically sends within the framework of a dialogue with the device (2) an impulse at an instant known with sufficient precision by the device (1) but which is not particularly related to a start instant the device (2) detects this pulse and measures the time difference, for example in microseconds, between this pulse and the next instant in image start - the device (2) sends by means of the transmission chain (4) to the system (1) a number which indicates to the system (1) what is the time difference calculated by the device (2); the sending of this information can be carried out with a transmission channel with a narrow bandwidth (a few kilohertz) the system (1) can thus reset its local clock (70)
- the device (2) can detect the pulse sent by the system (1) and date its time of appearance with the required precision.
- the synchronized clock and the internal time counters have been reset, it then measures the duration of the time interval T which begins at the start of the image and ends at l 'instant of the logic level change generated by the comparator supplied by the signal from the sensor D, the detection field of which is limited to the zone Z pointed (this level change corresponds to the start of the passage of the spot in the zone Z targeted).
- the position in X is calculated from an average of times between the start of the illumination of the sensor D1 and the start of the illumination of the sensor D of the same scanning line.
- the remark made previously on the meaning of the Modulo operation (Line) shows that the position in X is calculated from an average of values similar in nature to those provided by the Modulo operation.
- each point of the screen is therefore set to a very clear value before being refreshed
- the illumination sensor D consists, in FIG. 3, of an illumination detector 50 possibly placed at the bottom of a narrow tube 51, the inner surface of which absorbs the light rays 52.
- the sensor D comprises, in addition to the detector 50 and the tube 51, an optical lens system 53, which can be assimilated optically to a convex lens. This system makes it possible to improve the sensitivity and directivity of the sensor by focusing on an active part of the detector 50, since the light rays coming from the targeted zone Z are captured by the system whose surface is clearly greater than that of the detector.

- a device such as a cone which focuses the optical rays on the sensitive surface of the photoelectric sensor can be added - any optical device with a sufficiently wide field such as lenses with very short focal length or a parabolic receiver with too little directivity can also be used.
- the device may include means for indicating to at least one of the control systems that the signals transmitted by this system are not understandable, or that the device is waiting for information of a very specific type from the of the control system.
- the device (2) can request information of different types, for example in the following cases:
- Information requests of different types can be selectively intended for one or more systems and emitted by the transmission channel used for the transmission of pulses or start of image information.
- control system (1) It may be useful to minimize the energy consumption of the control system (1) by transmitting information to the device (2) only if the position of the target Z zone varied by a determined percentage and / or during a determined period of time.
- the graphic cursor (40) (FIG. 1) displayed by the device (2) on the screen (3) to materialize the position Z aimed by the user can take the form of any graphic effect viewable by the user, such as for example a change in color or shape of an object or the flashing display of any geometric shape.
