Definitions
- EP 1 696 300-A1 describes a so-called optical joystick.
- a pivotally mounted lever is provided at one end with a light source which illuminates in response to the position of the lever on a certain area of a surface provided with a field of photosensitive cells.
- the electrical signals generated thereby by the cells are read by a computer and interpreted so that the joystick from the user's point of view has the same effects on the computer as a joystick in which the position is removed via ohmic resistors.
- the joystick moves a cursor icon on the computer screen.
- a specific action can be triggered by pressing a button or the Enter key.
- the photosensitive cells which are illuminated by the lever of the cursor, are normally not seen by the operator. With appropriate construction you will end up with a small area of light-sensitive cells.
- EP 354 996 A2 and EP 225 625 A2 describe optical position-measuring devices in which fluorescent molecules are arranged on or in an optical waveguide surface, which convert light incident from the outside into longer-wavelength, diffusely scattered light, which in the guided to the surface edges of the optical waveguide surface and is either already detected in its intensity by sensors or only at another location to which it is guided via optical fibers. Since the intensity of the measured light decreases with the distance to the point of impact of the light beam, it is possible to deduce the point of impact of the light beam by combining the measurement results from a plurality of sensors. The use of this principle for an input device of a data processing system is not contemplated in these documents. The position resolution is also not sufficiently good for larger areas, since in the present documents, the detectors are usually mounted on the edge of the waveguide.
- ERS ⁇ TZBLA ⁇ (REGB, 26> which is in contact with the waveguide of the touchpad, couples light from an external source into the waveguide of the touchpad via scattering at the surface of the article.
- the detection of the location of the coupling is made possible with a photoelectric detector not described in detail.
- the position of a luminous pointer with respect to a screen is determined by means of a plurality of photodiodes, which are arranged next to the screen.
- the pointing beam is fanned out very broadly, its light intensity decreases from its center. From the knowledge of the intensity distribution over the cross-sectional area of the light beam, after measuring the intensity at the individual detectors, the distance to the cross-section center of the beam and thus to the point at which this beam center hits the display surface is recalculated.
- the achievable positional accuracy is relatively limited, in particular when there is a change in location of the pointing device which transmits the pointing device.
- US 2005/0103924 A1 describes a shooting training apparatus using a computer.
- the aiming device sends an infrared laser beam with a cross-shaped cross-sectional area to a screen connected to a computer.
- the edge of the screen is bordered by a series of photodiodes over which the computer detects the position of the cross-sectional area of the laser beam.
- the laser beam is briefly switched off by the target device, and the computer then displays the crossing point of the bars of the cross-sectional area of the laser beam before this interruption on the screen.
- the object underlying the invention is to provide a control device for a data processing system, wherein a light beam is transmitted to a control surface and the data processing system is influenced depending on the location of the light beam on the control surface, for example by a cursor position in a menu or on a virtual writing or drawing sheet.
- a control device for a data processing system, wherein a light beam is transmitted to a control surface and the data processing system is influenced depending on the location of the light beam on the control surface, for example by a cursor position in a menu or on a virtual writing or drawing sheet.
- a light beam is transmitted from a pointing device to a control surface, which is equipped with one or more optical position detectors, which are connected to the data processing system, depending on the location of the light beam on the control surface , the data processing system is affected.
- the light intensity of the light beam emitted by the pointing device onto the control surface fluctuates in predeterminable chronological pulse sequences which can be differentiated from one another.
- the pulse sequences representing, temporal variations in the intensity of the light beam are detected by a constructed as a planar luminescence optical waveguide, provided with photoelectric sensors position detector, the data processing system the individual pulse sequences according to a stored assignment rule assigns meanings.
- a pointing device can communicate various "signs" to the data processing system.
- the pointing device can have a number of different keys
- the data processing system recognizes this pulse sequence and assigns it a "meaning", such as the arrival of the input of a specific letter.
- the total duration of a pulse sequence may only be very short, for example lms.
- rapid optical position detectors are needed.
- the best such position detectors can be realized by planar luminescence optical waveguides, which are locally equipped with photoelectric sensors for coupling out light from the waveguide mode.
- Fig. 1 symbolically shows those elements of an exemplary device according to the invention, which are essential for the understanding of the invention. Light rays are symbolized by dotted lines.
- Fig. 2 shows an exemplary control surface formed by the display surface and position detectors in a front view. The cross-sectional area of a light beam is shown dotted.
- FIG. 3 shows an exemplary, idealized timing diagram for a possible intensity profile of a light beam emitted by a pointing device.
- a pointing device 1 transmits a light beam 2 to a control surface on which an optical position detector 10, which is composed of several layers 3, 4 and photoelectric sensors 5 for the generated electrical measurement signal. Via a frequency filter 6 (optional), the measurement signal reaches the data processing system 7.
- the optical position detector 10 consists for example of two approximately 0.1 mm thick cover layers 3 made of PET, between which an approximately 0.001 mm thick layer 4 of a homogeneous mixture of the plastic polyvinyl alcohol and the dye rhodamine 6G is laminated.
- the PET layers 3 form an optical waveguide with the layer 4 therebetween.
- Layer 4 is photoluminescent.
- silicon photodiodes as photoelectric sensors 5, which have a cross-sectional area of about 2x2 mm 2 are attached to the exposed side of one of the two PET layers 3 so as to emit light from the PET layer decouple and couple to their pn junction.
- the signals of all the photoelectric sensors 5 are supplied via electrical lines and a frequency filter 6 of a data processing system 7 in which they are measured and processed.
- a light beam 2 with a suitable spectrum strikes the layer 4, it triggers luminescence in the integrated particles.
- the resulting, longer-wave light is coupled in large part in the waveguide formed by the layers 3 and 4.
- the light in the waveguide mode is attenuated by the distribution and attenuation in the waveguide.
- a different intensity of the light in the waveguide mode is measured at the photoelectric sensors 5, depending on how far the Impact of the luminescence generating light 2 is removed from the photoelectric sensor 5.
- any number of photoelectric sensors preferably in a regular pattern, can be mounted on the surface.
- a dye transparent to the emission of transparent adhesive can be used, which produces a good optical contact between waveguide and photoelectric sensor 5. The closer the sensors are mounted, the greater the signal and, accordingly, the resolution of the component with the same readout electronics.
- an accuracy better than +/- 1 mm was achieved with a 12 cm sensor spacing in a square pattern.
- the described construction based on luminescence waveguide for a position detector which can be embodied as a surface can achieve very high temporal resolution of the measurement result.
- An inventive optical position detector 10 can be realized, for example, as a layer on a projection screen serving as a display surface for a data processing system.
- optical position detectors 10 may also be mounted in the form of narrow strips on the edges of a display surface 11 for a data processing system.
- the position detectors 10 are capable of detecting with respect to their longitudinal direction the position of a light spot impinging on them.
- the light beam 2 of the pointing device is visible in cross-sectional view. This is formed by two perpendicular and intersecting lines. The position of the intersections of these lines at the individual position detectors 10 is forwarded by the individual position detectors to the data processing system to be controlled.
- the data processing system can the position of the intersection of the two cross-sectional lines of the pointing beam.
- these coordinates can be assigned the position of a cursor, that is to say an insertion mark, a cursor or an entry marker otherwise usually moved by means of a "mouse" on the display surface.
- the measurement accuracy in a wide range is independent of the distance of the pointing beam emitting pointing device.
- time interval t x in FIG. 3 sends a pointing device of a light beam, whose intensity pulsates with that in Fig. 3 in the time interval t x shown over time.
- This pulsing can be understood as a binary coding of a character, which sends the pointing device to the control surface, so that it is forwarded by the position detector arranged there to the data processing system as an input character.
- the duration of the time interval t x can typically be 10 ⁇ s.
- This signal is repeated at regular intervals t y , which are significantly longer than t x .
- the data processing system measures within a time interval D, which is greater than twice of t y, so that the data processing system always at least two pulse trains of duration t x within a measurement interval receives.
- the beginning or end of the interval t y is defined by a signal of the pointing device, one can assign information to the position of a shorter temporal sub-interval t x in the longer interval t y .
- a plethora of different characters can be easily encoded by the pointing device sending only one short pulse at a time within the interval t y which has been determined to be indicative of the character being sent.
- each individual pointing device can have an individual time interval t y , wherein t y is always shorter than half the duration of the interval D. Beginning / or. The end of t y does not need to be indicated by its own signal. to be drafted. From the time t y in which repeat the same pulse sequences - of which a single maximum tx - repeat, it is thus recognizable for the data processing system, from which pointing device they were sent.
- the number of pointing devices is mainly limited by the fact that the pulse sequences must not overlap each other during t x . However, this is rarely the case with very fast signals and few pointing devices (eg four), so that these errors can be ignored.
- the coding of characters by pointers can be done regardless of which point of the control surface the light beam of the pointing device points to. The possibility of position calculation remains unaffected.
- the time interval D can typically last 200 ⁇ s.
- multiple pointing devices with multiple functionalities can be connected to an interactive screen without the need for a data connection between the elements except the light beam.
- the modulation frequency must be significantly higher than the frequency with which the binary encoding of characters is done by pulsing the light intensity.
- Another method of suppressing the background signal from ambient light is an upstream frequency filter that filters out all the low frequency signals from the detector signal but passes through the pulses, which are very high frequency. This can be achieved either with simple software solutions (e.g., by forming the second mathematical derivative) or via appropriate electronic circuitry.
- a number of inputs can be made with a pointing device without a direct data connection to a data processing system, which is not possible with previous methods. Furthermore, this allows the use of multiple input devices simultaneously, which can be independently recognized and identified. This allows a very comfortable Ie application, since no data connection via cable or radio must be installed.
