Abstract
The touching computer input device is one plate with three electrodes in certain spaces, or two, upper and lower, parallel planes with horizontal electrode bar and longitudinal electrode bar separately in them and with insulating layer in between. The present invention utilizes the change in capacitance and body's inductance, the positon of finger in electrode is measured and the capacitance signal is converted into voltage signal and digital signal fed to computer so as to control the translation of cursor in screen.
Description
The present invention relates to a kind ofly utilize human body sensing and, belong to the computer equipment field to the touching computer input device of computer input information.
Existing computing machine input unit has Genius mouse, trackball and inductance pen, pressure sensi-tive pen or magnetic strength pen etc., and all there is complex structure in these input units, makes difficulty, and the cost price is higher, and breaks down easily and wait deficiency.In a single day these input units break down, and then directly have influence on computer user's relevant work, have both reduced work efficiency, send maintenance again, even buy new input unit.
Purpose of the present invention is exactly at the deficiency described in the above-mentioned background technology, and a kind of operation simple in structure, easy is provided, cost is lower and long-lived touching computer input device.
The objective of the invention is to be achieved through the following technical solutions: this touching computer input device is three electrodes that a base plate is provided with mutual isolation, produces a capacitor C y and Cx respectively between per two electrodes.
Also can cross one another and be separated with insulation course between the horizontal stripe electrode that is provided with and the taeniae electrode in horizontal direction on the base plate.Said horizontal stripe electrode and taeniae electrode are upper and lower equidistant intervals.
Fig. 1: structural representation of the present invention.
Fig. 2: another structural representation of the present invention.
The A-A cut-open view of Fig. 3: Fig. 2.
Now in conjunction with the accompanying drawings the present invention is described in detail.
As shown in Figure 1, be provided with three plate electrodes 1,2,3 of isolating mutually on the same plane of a base plate of being made by insulating material 4, wherein electrode 1 is parallel to each other with two limits of electrode 3 with electrode 3 and electrode 2.There are a capacitor C y and Cx between the electrode 1,3 and 2,3 respectively.Usually capacitor C y, Cx value are very little, and when people's finger or hand-held conductor contact electrode 3, the capacitor C y between the electrode 1,3 will change and increase.This is because behind the finger contact electrode 3, due to the dielectric coefficient between the electrode 1,3 has taken place to change.Size that capacitor C y changes and the distance dependent between finger and the electrode 1, finger distance electrode 1 is near more, and it is big more that Cy just becomes, otherwise just more little.In view of the above can by the size of Cy variable quantity determine the finger on electrode 3 with electrode 1 position apart, the Cy changes in capacitance is changed into the variation of voltage by circuit, become digital signal input computing machine again, just can predict the position that finger moves on electrode 3, and then the control cursor situation that Y direction moves on screen.
In like manner, when finger on electrode 3 when mobile, the capacitor C x between the electrode 2,3 also can change, by with measure the same circuit of capacitor C y, can be in the movable signal input computing machine of directions X finger, in order to control cursor the moving of X-direction on screen.
As shown in Figure 2, equidistant horizontal stripe electrode 5 and taeniae electrode 6 are divided into upper and lower two planes intermesh and in the middle of separate (referring to Fig. 3) by insulation course 7 and be positioned on the base plate 4.When finger or hand-held conductor when moving to certain mutual cross-coincidence position of horizontal stripe electrode 5 and taeniae electrode 6, will produce a capacitor C x to horizontal stripe electrode 5 because of the finger induction, and taeniae electrode 6 is produced capacitor C y, can predict the physical location of capacitor C x and capacitor C y by metering circuit, change capacitance variations into change in voltage, become again in the digital signal input computing machine, thereby with regard to controllable cursor mobile state on the x of screen axle and axle y.
The said base plate 4 of the present invention is made for insulating material such as plastics, glass etc.; Said electrode is that the material that conductor such as copper, aluminium, stainless steel, lead etc. can be made electrode is made.Horizontal stripe electrode 5 must equate with distance between the taeniae electrode 6, and upper and lower two planes are not limited to any angle setting.
The present invention has overcome existing Genius mouse, trackball and inductance pen, a pressure sensi-tive pen and magnetic strength complex structure, damage easily, cost height, the high deficiency of price, utilize human body sensing and capacitance principle, have simple in structure, easy making, easy to use, not fragile and cost, advantage that price is lower, can extensively be used as the input unit of any computing machine.
