Embodiment:
Referring to Fig. 1-Fig. 3; Touch/remote-control computer display device, it comprises display screen, on said display screen, is coated with the corresponding transparent plexiglass plate 1 of size; On at least two adjacent angular signal receiving device 2 is being installed on transparent plexiglass plate 1 frame; With the nib 3 contact sets triangularities of stylus 7,, confirm the exact position of nib 3 contacts through calculating through the signal that signal receiving device 2 acceptance are sent from stylus 7.Wherein:
Said stylus 7 is made up of penholder and nib, and said nib 3 is equipped with axial signal power valve, and order is equipped with signal power valve switch 4, mounting spring 5 and deviation meter 6 in the penholder behind said nib 3; Dynamics through nib 3 contact transparent plexiglass plates 1 produces displacement, enabling signal power valve switch 4, and convert pressure to displacement signal through displacement measuring device 6;
Increase a signal receiving device in the nib 3 of said stylus 7;
Increase a visible light parallel in the nib 3 of said stylus 7 as UltraVNC with the phasing signal source;
Said transparent plexiglass plate 1 is replaced by irreflexive focussing glass;
Change the said signal receiving device 2 that is installed on the transparent plexiglass plate frame into sender unit, change the nib 3 of stylus 7 into signal receiving device, as the same;
Also two above signal receiving devices can be installed on transparent plexiglass plate 1 frame; Form a plurality of triangles by nib 3 contacts and two adjacent signals receiving traps often, thereby draw a plurality of location points, through COMPREHENSIVE CALCULATING; Get its mean value, draw more accurate mouse position point.
Referring to Fig. 4, on common computer,, cover on the computer screen with transparent poly (methyl methacrylate) plate 1.This glass plate is suitable with the computer screen size; And two ultrasonic signal receiving trap 2 (CTC40-16S1 are installed at the angle on its two; Shenzhen gold gathers precious electronics technology); The nib 3 of stylus 7 (CTC40-16F1, Shenzhen gold gathers precious electronics technology) is equipped with axial signal power valve and can sends the range finding ultrasonic signal.When nib 3 contact glass plates, switch 4 (IT-1184) starts, and makes microprocessor 8 (CJ-3A ultrasonic ranging external member.Shenzhen gold gathers precious electronics technology) send the continuous impulse signal.The sender unit transducing of pulse signal on nib sends ultrasonic pulse signal, and this signal is passed to two signal receiving devices 2 through poly (methyl methacrylate) plate 1.
Nib 3 adds these two fixed ranges of going up 2 of angle signal receiving traps to the distance of each signal receiving device 2, has formed three sides of a triangle.According to how much laws,, can obtain the relevant position mouse point of nib 3 on computer screen indirectly through triangulation calculation.Thereby play the effect that replaces mouse to shield enterprising line operate at computer touch with stylus 7.
Wherein: in stylus 7, signal emission switch 4 is housed behind the nib 3, mounting spring 5 thereafter.
When nib 3 contact transparent plexiglass plates 1,4 work of trigger pip emission switch, and convert pressure into electric signal through displacement measuring device 6 (scientific & technical corporation is washed one's hair in sky, NS-1 Shanghai) and send to microprocessor 8.Stylus 7 is cooperated with existing corresponding computer software, can imitate out the function of the various soft pen that uses in writing brush, the oil painting brush class software.On display screen, directly write like this, paint, more can use more convenient, nature, better effects if near people's custom.
Referring to Fig. 7, the workflow of 7 nibs 3 D point coordinate on display screen of calculating stylus is following:
When the nib 3 of stylus 7 touched display screen D point, stylus 7 sent working signal to microprocessor 8, the signal generator in the microprocessor 8, and beginning is regularly sent per second 50 times to stylus 7, and each 100 frequencies are the 40khz pulse signal; Stylus 7 is converted into ultrasonic pulse with pulse signal.Pulse is at t
