Description

Computer-Muis gebaseerd op een daarin aangebracht stelsel van versnelling-opnemers. Computer-Mouse based on a therein mounted system of acceleration sensors.

De uitvinding heeft betrekking op een bij computers gebruikt besturings-hulpmiddel meestal aangeduid als een muis, gebruik makend van in dit apparaat geplaatste versnelling-opnemers, en een electronische schakeling die de door deze versnelling-opnemers gekonstateerde versnellingen/vertragingen omzet in door de aangesloten computer verwerkbare informatie ontrent met deze muis uitgevoerde bewegingen. The present invention relates to a usually referred control device used in computers as a mouse, using placed acceleration sensors in this device, and an electronic circuit that the accelerations / decelerations gekonstateerde by these acceleration sensors turnover by the connected computer processable information ontrent with this mouse movements performed.

Bij gebruikelijke muizen wordt meestal van een over het werkblad voortbewogen balletje gebruik gemaakt om de door de bedienende persoon gemaakte handbewegingen om te zetten in door de computer verwerkbare informatie (mechanische variant). In normal mice, is usually made of a propelled ball use the worksheet to hand movements made by the operator to use the computer processable information (mechanical version).

Ook is een uitvoering bekend waarbij van een optische methode gebruik wordt gemaakt om beweging ten opzichte van een speciaal geprepareerd werkblad waar te nemen (optische variant). Also, an embodiment is known in which use is made of an optical method to sense movement relative to a specially prepared worktop (optical variant).

Bij de mechanische variant is door vervuiling en slijtage van het mechanisme vaak sprake van onbetrouwbare werking van het apparaat, tevens wordt de nauwkeurigheid ervan door mechanische toleranties beperkt. In the mechanical variant, by contamination and wear of the mechanism often involve unreliable operation of the apparatus, at the same time is limited by the mechanical tolerances its accuracy.

Bij de mechanische variant dient altijd een glad en stabiel werkvlak aanwezig te zijn, bij de optische variant dient dat werkvlak tevens voor het doel geprepareerd te zijn. In the mechanical variant must always be present a smooth and stable work surface, in the optical variant must working surface which at the same time to be prepared for the purpose.

Bij geen van de twee varianten is het eenvoudig een driedimensionale versie van het systeem te construeren. None of the two variants is easy to construct a three-dimensional version of the system.

De uitvinding beoogt het vaststellen van beweging door middel van een twee-assig of drie-assig stelsel van versnelling-opnemers, hiervoor kunnen zowel opnemers gebaseerd op electro-magnetische principes alswel opnemers gebaseerd op piezo-electrische principes worden ingezet. The invention aims at the determination of movement by means of a two-axis or three-axis system of acceleration sensors, sensors for this purpose can be either based on electro-magnetic principles alswel sensors are deployed based on piezoelectric principles. In figuur (a) wordt een komplete principe-schakeling voortvloeiend uit EEN versnelling-opnemer uitgewerkt. In Figure (a) comprises a complete in-principle circuit is elaborated arising from an acceleration sensor. Per waar te nemen bewegings-as zal een dergelijke schakeling worden toegepast. As can be observed as motion will be applied to such a circuit.

De electrische signalen voortgebracht door de versnelling-opnemer(1) worden na eventueel noodzakelijke versterking door een versterker-schakeling(2) aangeboden aan een Integrator-schakeling(3), die de aangeboden signalen integreert volgens het patroon volgens figuur(b), als volgt: (de uitgevoerde beweging is het uit stilstand versnellen van de opnemer in de gevoelige richting, overgaan in onversneld voortbewegen en het tot stilstand brengen van de opnemer, curve(1) geeft het signaal op de ingang van de integrator (figuur(a), punt(5)) weer, curve(2) geeft het signaal op de uitgang van de integrator (figuur(a), punt(6) weer). The electrical signals generated by the acceleration sensor (1) are, after any necessary amplification by an amplifier circuit (2) is presented to an integrator circuit (3), which integrates the applied signals according to the pattern according to Figure (b), and follows: (the output motion is the acceleration from standstill of the sensing element in the sensitive direction, pass into onversneld advancing and bringing to a standstill of the sensor, curve (1) shows the signal at the input of the integrator (figure (a) , item (5)), again, curve (2) indicates the signal at the output of the integrator (figure (a), item (6) again).

Fase 1: versnelling van de opnemer, curve(1) is een representant van de ondervonden versnelling, curve(2) is een sommatie van de waargenomen ingangs-waarden van de integrator over de tijd waarop de versnelling plaatsvindt. Phase 1: acceleration of the sensor, curve (1) is a representative of the acceleration experienced, curve (2) is a summation of the detected input values ​​of the integrator on the time at which the acceleration takes place.

Fase 2: overgang naar onversnelde beweging, curve(1) gaat van een aktieve waarde via het nul-punt en een reeks negatieve waarden, waarvan de integraal gelijk is aan de in fase 1 berekende integraal van de versnelling-waarden. Phase 2: transition to dirt accelerated motion, curve (1) passes from an active value by the zero point and a range of negative values, the integral of which is equal to the integral of the acceleration values ​​calculated in stage 1. De uitgang van de integrator, curve(2), behoudt de waarde van de laatst berekende sommatie in fase 1. The output of the integrator, curve (2), and retains the last calculated value of the summation in phase 1.

Fase 3: overgang van onversnelde beweging naar stilstand, curve(1) is een representant van de ondervonden negatieve versnelling, de waarde op de uitgang van de integrator, curve(2), wordt afgebouwd als funktie van de sommatie van de waargenomen ingangs-waarden over de tijd waarop de vertraging plaatsvindt. Phase 3: transition of non-accelerated movement to a standstill, curve (1) is a representative of the perceived negative acceleration, the value on the output of the integrator, curve (2), is being phased out as a function of the summation of the sensed input values about the time when the delay occurs. Na het tot stilstand komen volgt eveneens een signaal waarvan de integraal gelijk is aan sommatie van de verragings-signalen, de uitgang van de integrator, curve(2) behoudt echter de waarde nul. After it has stopped is also apparent, a signal of which the integral is equal to the summation of verragings signals, the output of the integrator, curve (2), however, retains the value of zero.

De door de integrator-schakeling(3) afgegeven electrische waarde is hierdoor een representant van de op enig moment door de muis uitgevoerde beweging, deze waarde wordt aangeboden aan een schakeling(4), die deze electrische waarde omzet in door de aangesloten computer verwerkbare informatie over de door de Muis uitgevoerde beweging. The by the integrator circuit (3) is output electric value is therefore a representative of the offered by the mouse executed movement, this value at any given time in a circuit (4) that this electrical value into by the connected computer processable information the movement performed by the Mouse.

Aan de Integrator-schakeling(3) is een kontakt(7) verbonden, wat als funktie heeft het op nul stellen van de integrator-schakeling, en het (de-)aktiveren van de integrator-schakeling. To the integrator circuit (3) is a contact (7) is connected, which, as a function, the zeroing of the integrator circuit, and the (de-) activation of the integrator circuit.

Hiermede kan middels kontakt met een werkblad, of middels een handkontakt, het door de gebruiker willen aktiveren van de muis worden aangegeven. Herewith can be indicated by contact with a surface, or by hand contact, the mouse to activate the user.

Aan de schakeling (4) die de vertaling naar voor een computer verwerkbare gegevens verzorgt, zijn een of meerdere kontakten(8) verbonden die een door de computer te verrichten aktiviteit aangeven (zgn muistoetsen). On the circuit (4), which takes care of the translation into a computer-processable data, one or a plurality of contacts (8) connected to that indicate an activity to be performed by the computer (so-called mouse buttons).
