- - Figure 7 shows an alternative embodiment of the method for calculating the target position on the screen; and - Figure 8 shows an alternative embodiment of the control unit comprising two illumination sensors having reduced detection fields.
- the interface assembly takes, for example, the form of a remote control unit 1 intended to be used by an operator to control the operation of an electronic device 2 which is associated with a cathode-ray screen 3.
- the electronic device 2 makes it possible to display information on the cathode-ray tube screen 3 such as a fixed or animated video image, texts, or menus or the like. From the information displayed on the cathode screen 3, the operator makes a choice and / or enters data using the control unit 1 placed at a distance from the screen 3 and which will be described below.
- the control unit 1 comprises two illumination sensors D1 and D2 such as photo-diodes whose axes can be parallel and neighboring, but whose capture angles are different.
- the detection field of one of the detectors is wide and contains the entire screen 3, while the detection field of the illumination sensor D2 is reduced and is limited to one zone Z of the screen pointed inside the screen surface.
- the zone Z is in the form of a square or a rectangle, the ratio of the sides of the zone Z to the sides of the screen 3 will be approximately between for example 0.1 and 0, 01.
- the illumination sensor D1 includes a detection field which contains only the upper left part of this screen.
- the illumination sensor Dl is adapted so that its detection field contains the entire screen 3, or alternatively only the upper left part of the screen, even when the user targets the lower right part of said screen with its housing. remote control 1.
- the light sensor Dl consists of a simple light detector or, as is more particularly shown in FIG. 2, it consists of a light detector 45 upstream of which, relative to the direction of displacement of the light rays 46, a conical mirror 47 is placed. This mirror defines an angle making it possible to concentrate the incident rays towards the detector 45.
- the conical mirror 47 can be replaced by a system of wide angle optical lenses for focusing the light rays 46 on the active surface of the illumination detector 45.
- the illumination sensor D2 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 D2 comprises, in addition to the detector 50 and the tube 51, a system of optical lenses 53, which is optically comparable 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, because the light rays 52 coming from the targeted zone Z are picked up by the system whose surface is clearly greater than the detector.
- 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 D2 comprises, in addition to the detector 50 and the tube 51, a system of optical lenses 53, which is optically comparable 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, because the light rays 52 coming from the
- the light rays 52 coming from the targeted zone Z are picked up by the lens system 53 then are reflected on a mirror 54 before being returned to the detector 50.
- the mirror 54 can be formed by a plane mirror.
- the focal length of the focusing device which corresponds to the lenses 53 and to the mirrors 54 is much greater than the dimensions of the active part of the detector 50, so that this focusing device provides for the detector 50 a function similar to that of 'a telephoto lens in photography.
- the light rays 46 and 52 come from the cathode screen 3 placed at a distance so that these rays can be considered as coming from a common and distant source, and as substantially parallel to each other if the axes of the sensors Dl and D2 are close and parallel.
- the signal supplied by the sensors Dl and D2 consists of white noise and a current proportional to its illumination.
- Each sensor is connected to an assembly performing the following functions:
- Signal amplification must have the highest possible bandwidth to provide a position calculated with good accuracy.
- Photo-diodes have a very fast response time, on the order of a microsecond.
- the detection of the light spot in the capture field of each illumination sensor Dl and D2 is carried out by means of comparators supplied by the alternating signal supplied by the amplification stages and whose reference voltage is adjusted to a level higher than that of ambient noise.
- each comparator is of the LM329 type, the reference voltage of which is established at 6 dB above the white noise level.
- the two comparators are connected to a microcontroller 60 which makes it possible to measure the instant when the logic signal corresponding to each sensor has changed.
- the microcontroller must allow time measurements with an accuracy of 0.5 or 1 microsecond on several logic signals simultaneously. It is possible to use a microcontroller manufactured by STMicrotechnics in the ST7 range, which includes means for acquiring sufficient input time data and RAM capacity, and whose maximum processing speed allows in less than 64 microseconds to process the logic signal associated with the sensor Dl as well as the logic signal associated with the sensor D2.
- the microcontroller is for example configured as follows:
- the first timer has its two channels configured for data acquisition, which allows the microcontroller to automatically memorize in its memory the instant of appearance on its pins of each of the logic signals associated with the start of the illumination of the sensors Dl and D2 and generate an interrupt for each of the logic signals;
- the second timer generates periodic interruptions and serves as the system clock.
- Certain video signals have a line frequency much higher than that of the PAL, SECAM or NTSC standards (which is of the order of 16 Khz, which corresponds to a line duration of approximately 64 microseconds).
- the screens of computer monitors have line frequencies of 60 KHz or more, which corresponds to a line duration of 16.7 microseconds or less.
- the microcontroller 60 is connected to the user interface allowing the user to indicate that the box must perform a position measurement of the zone Z.
- the microcontroller proceeds as follows (with reference to FIG. 6): - it monitors the logic level of the signal coming from the illumination sensor Dl whose detection field includes only the upper left part of this screen;
- the period of time corresponding to the passage of the spot from the lower right corner of the screen to the upper left corner of this screen varies from 1 to 2 milliseconds according to European or American television standards (PAL, SECAM, NTSC ) and no new line or image is then displayed on the screen during this period.
- the microcontroller when the detection field of the sensor Dl includes only the upper left corner of the screen and knowing that the spot scans a line of the screen in approximately 64 microseconds, the microcontroller will be able to detect the absence of the spot in the detection field of the Dl sensor. When the period of absence of the spot in the detection field of the Dl sensor is at least equal to 1 or 2 milliseconds, the microcontroller is then able to know that the reappearance of the spot will necessarily be in the upper left corner of the screen . Similarly, when the detection field of the Dl sensor includes the entire screen and knowing that the spot always scans a line of the screen in approximately 64 microseconds, the microcontroller will also be able to detect the absence of the spot in the detection field of the Dl sensor.
- the micro- controller is then able to know that the reappearance of the spot will necessarily be in the upper left corner of the screen.
- This detection of the absence of illumination of the Dl sensor for a period of at least 1 to 2 milliseconds can be directed by the microcontroller or by a suitable electronic circuit disposed at the output of the comparator associated with the Dl sensor, this circuit then sending a signal to the microcontroller;
- the microcontroller assigns to this first signal the instant T1 which corresponds to the start of scanning of a new image.
- the microcontroller can also systematically ignore the first signals emitted by the sensor D1, for example the first three signals which correspond to the scanning of the first three lines and assign to the fourth signal 1 instant Tl which then corresponds to the start of scanning of a new image (FIG. 6). Indeed, it can be useful to ignore at least the first three scan lines of the screen given the fluctuations in the speed of the spot during the first scans.
- the signal corresponding to the start of image scanning is understood to mean not the signal emitted by the scanning of the first line of the screen, but the first signal emitted by the sensor Dl which will be detected. and stored by the microcontroller 60;
- the micro- controller can assign the instant T2 to the level change which corresponds to the start of the passage of the spot in the target area, that is to say to the first line of the target area or then to the corresponding logic level change, for example , on the fourth passage of the spot in the targeted zone Z, consequently ignoring the first three signals emitted by the sensor D2.
- the arithmetic processing means of the housing or of the electronic device 2 then calculate the position of the start of the targeted zone Z from the instants T1 and T2 according to the following principle:
- the operation Whole value [(T2-T1) / Line] amounts to eliminating from (T2-T1) the duration which corresponds to a fraction of a line. Consequently, Integer value [(T2-T1)] is directly comparable and equal to the time which elapses between on the one hand the start of the illumination of the sensor Dl at the start of the scanning of the image (instant Tl) and on the other hand the start of the lighting (left edge of the screen 3) of the first scanning line which illuminates the sensor D2; -the Modulo operation (Line) amounts to subtracting from (T2-T1) the duration corresponding to the scanning of the lines of the screen 3 before the sensor D2 is lit.
- the electronic device permanently displays a portion 58 of light color (FIG. 1) in the upper left corner of the image displayed on the screen 3.
- This portion is of reduced dimensions compared to the screen, and is for example of square shape whose side is equal to 2 to 5% of the value of the diagonal of the screen.
- the portion 58 is white in color.
- the microcontroller 60 can also proceed as follows ( Figure 6):
- the microcontroller 60 only validates the memorization of the instant T3 if the light spot also illuminates the sensor D2 in a period of time less than the duration of total line scan, i.e. approximately 64 microseconds.
- the arithmetic processing means of the box or of the electronic device 2 then calculate the position of the start of the targeted zone Z from the instants Tl, T2 and T3 according to the following principle:
- the microcontroller can memorize several moments of illumination of the sensors D1 and D2. In this case, the microcontroller can proceed as follows:
- the arithmetic processing means of the housing or of the electronic device 2 then calculate the position of the start of the targeted zone Z from the averages previously calculated according to the following principle:
- - the position in Y is calculated according to an identical principle, by replacing isolated values by means of these same values, - the position in X is calculated from an average of times between the start of the sensor illumination
- the microcontroller 60 can memorize several instants Tl and T2 and proceed to calculate the position of the targeted zone Z only with the means Ml and M2 and by applying the calculation method involving the Modulo operation.
- the microcontroller will be able to calculate the X position of the target area from M2 and Ml and applying the Modulo operation and / or to starting from M3 and Ml and also proceed to an average of the results obtained by these two calculation methods to determine the position in X of the zone Z targeted.
- the imprecision provided by these averages is very small in view of the number of lines of a television image (250 to 280 lines useful typically in PAL, SECAM, NTSC each l / 50th or l / 60th of a second) and the improvement of the stability and reproducibility of the measurements provided by these averages.
- the capacity of the logic and arithmetic processing means of the box or of the electronic device 2 is minimized by the reduction in the number of signals transmitted to them and by the reduction in the number of information transmitted. towards the electronic device to materialize the position of the zone Z targeted by a cursor. This also makes it possible to minimize the energy consumption used by these processing means. For example, there is no transmission of information to the electronic device if the position of the targeted area has not varied by a predetermined percentage and / or during a predetermined period of time.
- the graphic cursor 40 displayed by the system 2 on the screen 3 to materialize the position targeted by the user can take the form of any graphic effect viewable by the user, such as for example a color change or shape of an object or the blinking display of any geometric shape.
- the control unit also has means for controlling the electronic device associated with the screen. These are means that can be positively actuated by the user such as keys, potentiometers, pressure sensors, a voice command or even one or more joysticks allowing the user to transmit information to the electronic device 2.
- the electronic device corresponds for example to a video game, it is a question of indicating a movement or of simulating a shooting or even, when the device corresponds to a television, it is for the operator remotely select an option from a TV program menu.
- control unit can comprise two sensors D2 and D3 different from parallel and neighboring axes, having detection fields which are each limited to one reduced area Z, Z 'of the screen.
- the presence of the second illumination sensor D3 advantageously allows the box to measure the position of the two distinct zones Z and Z 'on the screen 3, and therefore to deduce therefrom an angle of rotation of the box relative to the common axis.
- the management of two sensors D2 and D3 can for example be carried out as follows:
- each sensor D2 and D3 is associated with an amplification and filtering chain, as well as with a logic comparator,
- an assembly of logic gates and flip-flops allows the microprocessor 60 to be presented alternately with the logic signals from the comparators associated with each of the sensors D2 and D3 and providing it with the indication of the sensor D2 or D3 to which the signal corresponds,
- the microprocessor program 60 is adapted to process this alternation of signals or the signal from the new sensor D3 and calculate the position of the two zones Z and Z '.
- the microcontroller 60 or the electronic device 2 can then deduce therefrom the position of the medium between these two zones Z and Z 'and the angle of rotation of the segment formed by these two zones Z and Z' with respect to a reference axis formed by the common axis C of the two sensors D2 and D3.
- control units can be associated with a single electronic device, in particular when several players simultaneously use the same video game. It is then necessary that each of the control boxes has means identification to allow the electronic device to recognize each of these boxes.
- each of the control units can further comprise means for re-transmitting the information to be transmitted to the electronic device to minimize the probability that two control units transmit simultaneously and therefore to increase the probability that the information is correctly received by the device.
- electronic The control unit can also contain a combination of identification means electrically accessible by the microcontroller 60, such as electronic memories containing a serial number or a set of electrical contacts such as a set of switches which conditions the logic level on input pins of the microcontroller 60. The information provided by these identification means can be taken into account by the microcontroller 60 in the calculation of the information to be transmitted, in particular in the following ways:
- each of the control units can, in addition:
- the control unit can detect whether the user is moving away from or substantially approaching the screen. Indeed, when the sensor D2 targets an area which is completely contained in the screen, the duration of the illumination of this sensor varies in the same direction as the distance separating the sensor D2 from the screen 3. By measuring the direction and the intensity of the variation in this duration of illumination on, for example, the last 20 images observed, it is possible to estimate whether the user has moved away or approached the screen 3 appreciably. duration of illumination of the sensor D2 for each line being of the order of a few microseconds, and the typical variations of this duration being of a few percent, a particular method of measuring the illumination time is useful.
- the capacitor is initialized by a short circuit of its terminals produced by means of a MOS transistor controlled by the microcontroller 60 before the start of each image; - once per image, during a screen scanning line selected by the microcontroller 60 (for example the third), the capacitor is charged by a current or a constant voltage controlled by another MOS transistor which allows the charge current to pass only during the duration of the logic signal constituted by a logic AND of the following two signals:. the logic signal provided by the comparator associated with the sensor D2 (assuming that it is at 1 when the sensor D2 is lit),
- a logic signal generated by the microcontroller 60 the level of which is at 1 during the whole duration of the scanning line during which the measurement must take place (this signal can for example be a signal of duration substantially equal to the duration of two scanning lines and which is initiated by the illumination of the sensor D2 during the scanning line preceding that during which the measurement will take place).
- the charge current of the capacitor must be sufficiently intense (several milliamps or tens of milliamps) so as not to introduce significant errors during the subsequent period of waiting and measuring the voltage at these terminals.
- the measurement of the voltage across its terminals is then carried out once per image (for example as soon as the end of the illumination has been detected) by means of a converter.
- analog / digital integrated in the microcontroller 60 This measurement is typically carried out in a few micro seconds by current microcontrollers.
- the ST7 range includes microcontrollers fitted with such converters.
- the control unit (s) and the electronic device respectively have an information transmitter and receiver which communicate by cable or by waves such as electromagnetic waves (especially infrared or radio), or acoustic waves (especially ultrasound).
- the electronic device may include means for indicating to at least one of the control boxes that the signals emitted by this box are not understandable, or that the device is waiting for information of a very specific type from the from the remote control.
- the signals emitted by the boxes may not be understandable for various reasons, and in particular when several boxes send simultaneously.
- the device 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 boxes.
- the indication means can for example consist of a non-emission of an image by the cathode ray tube or by a selected part of the latter and this, for a predetermined time interval.
- This time interval may be short enough so that there is no deletion of an image for the human eye, but may be long enough for this deletion to be detectable by the control units.
- the time interval can for example correspond to a non-emission of an image during an image, either 1/50 th or 1/60 th of a second.
- These means of indication can also be the sending of a predetermined sequence of luminous intensities which can be assimilated to images or parts of images very bright, moderately bright or very little bright.
