Abstract

An optical indicating device comprises a control unit provided with a threshold value inside, a sensing unit and a timing unit, wherein the sensing unit senses whether a finger presses on the sensing unit, and the timing unit times lasting time of the finger pressing on the sensing unit. The control unit compares the threshold value and time timed by the timing unit, outputs a first click signal when the time timed by the timing unit is larger than the threshold value, and outputs a second click signal when the time timed by timing unit is smaller than the threshold value. The invention further provides a click operation achieving method of the optical indicating device.

Description

Optical indicating device and clicking operation implementation method thereof

Technical field

The present invention relates to a kind of optical indicating device, be meant the operating optical indicating device that to click and the method that realizes clicking operation especially.

Background technology

Optical indicating device is to utilize the light-emitting component in it to send infrared light; When finger moves on optical indicating device; Infrared light is radiated on the finger, and with after the image process optical lens imaging that forms, analyzes the difference value of image characteristic values in different time points; Judge direction and distance that finger moves, thereby realize that mouse function realizes moving of cursor.

But general optical indicating device can't be realized the function of the right and left key of mouse; If will realize that this function need be provided with a button at the optical indicating device periphery; Thereby the user uses this button to realize the function of pushing, and this kind structure can't be incorporated on the portable electron device (like mobile phone, music player etc.) greatly because of volume, though perhaps can be incorporated on this type of device; But because complex structure is unfavorable for further reducing such device size.

Summary of the invention

In view of above content, be necessary to provide a kind of size less and can conveniently realize the optical indicating device and the method for clicking operation.

A kind of optical indicating device; Comprise a control module; Be provided with a threshold value in the said control module, said optical indicating device also comprises a sensing cell and a timing unit, and whether said sensing cell sensing has finger presses on it; The said duration of timing unit timing finger presses on said sensing cell; Time of more said threshold value of said control module and said timing unit timing, and export one first click signal during greater than said threshold value, export one second click signal during less than said threshold value in time of said timing unit timing in time of said timing unit timing.

A kind of optical indicating device clicking operation implementation method may further comprise the steps:

One control module of one optical indicating device is provided with a threshold value;

Whether one sensing cell sensing of said optical indicating device has finger presses on it; If finger presses is arranged on it, the duration of a timing unit timing finger presses of said optical indicating device; And

Said control module compares the time and the said threshold value of said timing unit timing, if the time of said timing unit timing greater than said threshold value, is exported one first click signal; If the time of said timing unit timing is exported one second click signal less than said threshold value.

Compared to prior art, the various durations that optical indicating device of the present invention and clicking operation implementation method thereof are pushed through this sensing cell sensing finger has realized different clicking operation, thereby makes the optical indicating device volume less and easy to use.

Embodiment

See also Fig. 1; One preferred embodiment of optical indicating device clicking operation implementation method of the present invention is applied in the optical indicating device 10, and this optical indicating device 10 comprises a control module 11, a graphics processing unit 12, an image acquisition unit 13, a light-emitting component 14, a sensing cell 15 and a timing unit 16.

This control module 11 is connected to this light-emitting component 14, controls this light-emitting component 14 and sends and be used for shining the infrared light on user's finger.

This control module 11 is connected to this graphics processing unit 12; This graphics processing unit 12 is connected to this image acquisition unit 13; This image acquisition unit 13 is used for obtaining the image of infrared radiation on finger, and 12 pairs of these images of this graphics processing unit carry out digital processing and obtain image characteristic values, and send eigenwert to this control module 11; This control module 11 is judged direction and the distance that finger moves according to the eigenwert that receives, thereby the control cursor is done corresponding moving.

This control module 11 is connected to this timing unit 16, and this sensing cell 15 is connected this timing unit 16, and this sensing cell 15 can be various common condenser types or inductive touch; When finger presses in 15 last times of sensing cell; Sensing cell 15 is triggered and sends signal and give timing unit 16, and timing unit 16 picks up counting, when finger leaves sensing cell 15 and not when pushing; Sensing cell 15 no longer sends signal and gives timing unit 16; Timing unit 16 stops timing, and sends the time of being counted to said control module 11, simultaneously timing unit 16 zero clearings.Be provided with a threshold value in this control module 11; When the timing of this timing unit 16 during greater than this threshold value; This control module 11 outputs one first click signal, the signal when for example the left button of mouse is pressed is when the timing of this timing unit 16 during less than this threshold value; This control module 11 outputs one second click signal, the signal when for example the right button of mouse is pressed.

See also Fig. 2, it is the process flow diagram that this optical indicating device 10 is implemented clicking operation, and concrete steps are following:

Whether step S201, sensing cell 15 sensings have finger presses on it, if finger presses is arranged, to step S202, if do not have, whether then sensing cell 15 continues sensings has finger presses on it.

Step S202, timing unit 16 picks up counting, and then arrives step S203.

Step S203, whether sensing cell 15 sensing fingers continue to push in the above, if do not continue to push in the above, to step S204, if continue to push in the above, sensing cell 15 continues sensing.

Step S204, timing unit 16 stops timing, then arrives step S205.

Step S205, timing unit 16 sends its timing to control module 11, and step S206 is then arrived in timing unit 16 zero clearings simultaneously.

Step S206, control module 11 compares the timing of timing unit 16 and the threshold value that is provided with in it, is the timing of timing unit 16 greater than this threshold value? If greater than this threshold value, to step S207; If less than this threshold value, to step S208.

Step S207, control module 11 outputs first click signal.

Step S208, control module 11 outputs second click signal.
