Description
The present invention is the multiple spot contact information acquisition system of a kind of hand (and assigned object) and sensitive surface.
The present invention can be used as the equipment based on the computerized information input system of the spatial shape characteristic information of hand (and assigned object).
The present invention also is a kind of novel computer input, is a kind ofly can realize the traditional computer peripheral hardware, such as: the computer input of the partial function of equipment such as keyboard, mouse, touch pad, clipboard and touch-screen.
Input system of the present invention also is applicable to the relevant device of other occasions and installs as information input system.
Touch apparatus commonly used at present has touch pad, handwriting pad and touch-screen etc., and these equipment are all good for the effect of conventional occasion.But a common feature of this kind equipment in the market all designs at single-point (single-point contact), at the also not appearance of equipment of multiple spot contact, rare relevant patent documentation.
The ultimate principle of common single-point touches equipment has the type based on following several realization approach.
1. resistive technologies
The screen body portion of resistive touch equipment is a multi-layer compound film that cooperates very much with display surface, by one deck glass or organic glass as basic unit, the surface scribbles the conductive layer of layer of transparent, be stamped one deck outside surface cure process, smooth scratch resistant plastic layer above again, its inside surface also scribbles the layer of transparent conductive layer, has the transparent isolating points of many tiny (less than mils) that they are separated insulation between two conductive layers.
When the finger touch screen, the two conductive layers of usual mutually insulated has just had a contact in the position, touch point, cause is the even voltage field of 5V of a conductive layer connection Y direction wherein, make the voltage of detecting layer become non-zero by zero, controller detects after this connects, and carries out the A/D conversion, and with the magnitude of voltage that obtains compare with 5V get final product the Y-axis coordinate of touch point, in like manner draw the coordinate of X-axis, the common ultimate principle of all resistive technologies touch-screens that Here it is.Briefly, the principle of work of resistive touch equipment adds operating voltage at one group of resistor network exactly, when writing pencil or finger have touched touch-screen, obtain the coordinate of both direction by the variation of measuring the screen impedance matrix, thereby obtain writing pencil or finger position.Its horizontal and vertical changes in resistance can be similar to the slide rheostat of regarding two groups of linearities as.
The key of resistance class touch apparatus is material science and technology.Transparent conducting coating material commonly used has: 1. ITO, indium oxide, workplace coating; 2. nickel gold plating.Be not suitable as the workplace of electric resistance touch screen, can only be as visiting layer.
Commonly used have four-wire resistance type, five wire resistance types.Basic unit is added in the voltage field of both direction on the conduction workplace of glass by the precision resistance network, outer nickel gold conductive layer is used for being used as pure conductor.After touching, the method that timesharing detects internal layer ITO contact point X-axis and Y-axis magnitude of voltage records touch point position.
2. surface acoustic wave
Surface acoustic wave, hyperacoustic a kind of, at the mechanical energy ripple of the surperficial shallow-layer propagation of medium (for example rigid material such as glass or metal).By wedge shape tribrach (according to the strict design of the wavelength of surface wave), can accomplish orientation, the emission of low-angle surface acoustic wave energy.
The touch screen portion of surface acoustic wave touch apparatus can be the glass plate of plane, sphere or a cylinder, is installed in the front of CRT, LED, LCD or plasma display screen.This piece glass plate is a pure tempered glass, and without any pad pasting and overlayer, this point is different from other class touch screen technology.
Each has fixed the upper left corner of glass screen and the lower right corner vertically and the ultrasound transmitting transducer of horizontal direction, and two corresponding ultrasound wave receiving transducers have then been fixed in the upper right corner.Four peripheries of glass screen then are carved with 45 by dredging the very accurate reflection strip of close spacing.
Transmitting transducer is sent controller here by the touch-screen cable electric signal is converted into acoustic wave energy and transmits to the left surface, one group of accurate reflection strip by glass plate bottom is reflected into even face transmission upwards to acoustic wave energy then, acoustic wave energy is through the screen surface, reflection strip by the top gathers to become line to the right to propagate to receiving transducer again, and receiving transducer becomes electric signal with the surface acoustic wave energy that returns.
Transmit with the received signal waveform when not touching, the waveform of received signal is with just the same with reference to waveform.When finger or other can absorb or stop the object touch screen of acoustic wave energy the time, the acoustic wave energy that makes progress away by way of finger position is partially absorbed, and is reflected at that to receive on the waveform be that waveform has a decay breach on a certain moment position.Receive the corresponding finger of the waveform breach that blocked position signal attenuation, calculate that gap position gets promptly that the touch coordinate controller analyzes the decay of received signal and by the location determination coordinate of breach.The X that can both respond except general touch apparatus, the Y coordinate, the surface acoustic wave touch apparatus also responds the 3rd Z axial coordinate, just can perception user touch pressure sizes values.Its principle is that the damping capacity by the receiving signal attenuation place calculates.
3. capacitive sensing technology
The structure of capacitance touch equipment mainly is the thin-film body layer of plating layer of transparent on glass screen, adds the lastblock cover glass at conductor layer again, and conductor layer and inductor can be thoroughly protected in two glass designs.In addition, all plate long and narrow electrode, in electric conductor, form a low-voltage AC field on additional touch-screen four limits.During user's touch screen, because people's bulk electric field can form one " coupling capacitance " between finger and conductor layer, the electric current that four limit electrodes send can flow to the contact, and the power of electric current is accurately calculated touch point position.Its characteristics are higher for touching accuracy, and antijamming capability is stronger.But this type of touch apparatus is afraid of electrostatic interference.
Other also have the touch apparatus based on principle types such as infrared technique, electromagnetic techniques.Touch apparatus based on above these methods all designs at the single-point contact at present, can only discern the contact information of single contact point.
The publication information of relevant calculation machine input system:
