Description
Technical field
The invention belongs to position input equipment technical field, more specifically, it is related to a kind of twisted using wrist and senses
Positioning input device, it is similar with mouse, be related to computer, mobile phone, image generation and processing unit positioning input.
Background technology
Mouse is a kind of input equipment, is also the indicator of calculator display organization coordinate setting in length and breadth, because of likeness in form mouse
And gain the name " mouse ".American scientist Douglas Engelbart (Douglas Englebart) nineteen sixty-eight is in Jia Lifu
Ni Ya has made first mouse.Mouse is different according to working method, can be divided into：Mechanical mouse, optical machine mouse and photoelectricity mouse
Mark；According to different with the connected mode of computer, wired and wireless mouse can be divided into.
As shown in Fig. 1 (a), mechanical mouse with one can four-way rolling colloid bead.This bead can band when rolling
Dynamic a pair of axis of rotation (being respectively X rotating shafts, Y rotating shafts), have a circular decoding wheel, decoding wheel is upper attached turning the tip of the axis
There is metallic conduction piece directly to be contacted with brush.When the spindle is rotated, these metallic conduction pieces will be contacted successively with brush, be occurred
Two kinds of forms of " on " or "off", the former corresponds to binary number " 1 ", the latter's correspondence binary number " 0 ".Next, these two
Binary signal makees dissection process by the special chip delivered inside mouse and produces corresponding changes in coordinates signal.As long as mouse exists
Moved in plane, bead will drive axis of rotation, and then the break-make situation of decoding wheel is changed, produce one group of group different
Coordinate offset amount, be reacted on screen, be exactly that cursor can be moved with the movement of mouse.
As shown in Fig. 1 (b), optical machine mouse is improved on the basis of Purely mechanical mouse, by introducing optical technology
To improve the positioning precision of mouse.As Purely mechanical mouse, optical machine mouse equally possesses the small spin of a colloid, and even
Then X, Y rotating shaft, except that optical machine mouse is there is no circular decoding wheel, instead of be two gratings codes stitched with grid
Disk, and add light emitting diode and sensitive chip.When mouse is moved on the table, spin can drive the two of X, Y rotating shaft
Grating encoder is rotated, and the light that X, Y light emitting diode are sent will be radiated on grating encoder, because grating encoder has grid
Seam, the light gone out in appropriate opportunity diode emitter just can pass through the detection head that grid seam direct irradiation is constituted in two sensitive chips
On.If receiving optical signal, sensitive chip will produce " 1 " signal, if without optical signal is received, it is set into signal
“0”.Next, these signals, which are admitted to computing in special control chip, generates corresponding coordinate offset amount, determine that cursor exists
Position on screen.
Optical mouse does not have the design such as traditional spin, rotating shaft, and its critical piece is two light emitting diodes, photosensitive cores
Piece, control chip and one carry the reflecting plate of grid (equivalent to special mouse pad).Optical mouse must be anti-during work
Penetrate on plate and move, X light emitting diodes and Y light emitting diodes can launch light respectively and be radiated on reflecting plate, then light meeting
Gone back, be radiated at after lens assembly is transmitted on sensitive chip by baffle reflection.Sensitive chip is converted light signals into pair
It is sent to special disposal in positioning chip after the data signal answered, and then produces X-Y coordinate offset data.
Wireless mouse operation principle is identical with wire mouse, and simply its connected mode uses bluetooth or infrared connection, and does not have
Live wire is directly connected with the device such as computer.
Traditional positioning input device, such as mouse are required for independent carrying, also there is complicated, power consumption high and fragile
The problems such as.
The content of the invention

Include：
One wrister, the wrister can be enclosed in wrist；
Multiple voltage-controlled inductors, such as voltage controlled capacitor or thyrite equal distribution are in wrister surrounding, for detecting user's wrist
Left and right, twist up and down, the voltage-controlled induced signal of generation, and export process chip；
Process chip, for handling voltage-controlled induced signal, obtains corresponding positioning signal.
As a further improvement, also including a communication chip, need what is positioned for positioning signal to be sent to
Equipment, the process chip and communication chip are placed directly in wrister.
The object of the present invention is achieved like this.
The present invention twists the positioning input device of sensing using wrist, by a wrister that can be enclosed in wrist, and protects
I.e. wrist surrounding wrist surrounding is distributed voltage-controlled inductor, such as voltage controlled capacitor or thyrite.Turn round when wrist or so or up and down
When dynamic, the capacitance for producing voltage-controlled induced signal, i.e. voltage controlled capacitor changes signal, or the resistance value of thyrite changes signal,
Voltage-controlled induced signal sends into chip, handles and produces corresponding positioning signal., the present invention abandoned traditional positioning input device
The implementation of (mouse), directly use voltage-controlled sensing, the relatively conventional positioning input device of its circuit system (mouse) simply, easily
In realization, while can be integrated with wearable device, it is handy to carry about, meanwhile, its power consumption can also be reduced, and it positions speed
Degree and positioning precision can be improved, and not allowed fragile.The positioning for the utilization wrist twisting sensing that this patent is proposed is defeated
Enter device, with widely application prospect, such as replace mouse mapping, positioning.
