Embodiment
Mouse of the present invention comprises acceleration transducer, and with the acceleration of sensing mouse, and to change this acceleration be the acceleration sensing displacement.Mouse of the present invention also compares the optical displacement gauge that acceleration sensing displacement and optical sensor are sensed, and be used as the displacement of mouse with an acceleration sensing displacement and an optics sensed displacement amount preferable sensed displacement amount wherein, make mouse can normally operate in different desktop materials.
Please refer to Fig. 1, it shows the circuit block diagram according to the mouse of the embodiment of the invention.Mouse 102 is to couple with an electronic installation 104, and electronic installation 104 is for example to be computing machine in the present embodiment.Mouse 102 comprises acceleration transducer 106, micro-control unit (Micro Control Unit) 108 and optical sensor (Optical Sensor) 110.Optical sensor 110 is coupled to micro-control unit 108, and in order to detect the displacement of mouse 102, with output optical displacement gauge SOD.Wherein, optical displacement gauge SOD comprises vertical optical displacement component and lateral optical displacement component, and it is respectively the transversal displacement amount that vertically reaches of optical sensor 110 detected mouses 102.
For example for quickening rule (G Sensor), acceleration transducer 106 comprises transverse acceleration sensing cell 106a and longitudinal acceleration sensing cell 106b to acceleration transducer 106.Laterally reaching longitudinal acceleration sensing cell 106a and 106b couples with micro-control unit 108 respectively.Laterally and longitudinal acceleration sensing cell 106a and 106b respectively in order to the transverse acceleration and the longitudinal acceleration of sensing mouse 102, and respectively according to sensed laterally and longitudinal acceleration obtain transverse acceleration component SAx and longitudinal acceleration component SAy.Wherein, laterally and when vertically being respectively general use habit of mouse 102, the housing of mouse 102 vertically and laterally.
Next further specify as follows to micro-control unit 106 according to the operation that transverse acceleration sensed displacement component and lateral optical displacement component obtain horizontal mouse displacement signal.
When transverse acceleration sensed displacement component and lateral optical displacement component were unequal, micro-control unit 108 further judged whether transverse acceleration sensed displacement component is identical with the direction of lateral optical displacement component.When the direction of transverse acceleration sensed displacement component and lateral optical displacement component is inequality, expression mouse 102 operates on the desktop of the material that is unfavorable for light reflection, optical sensor 110 can't be on the desktop of this moment sensing lateral optical displacement component react the transversal displacement amount of mouse 102; Micro-control unit 108 is preferable transversal displacement amount with transverse acceleration sensed displacement component, and with this preferable transversal displacement amount as horizontal mouse displacement signal.
When the direction of transverse acceleration sensed displacement component and lateral optical displacement component was identical, micro-control unit 108 judged further that more whether the lateral optical displacement component is greater than transverse acceleration sensed displacement component.When lateral optical displacement component during greater than transverse acceleration sensed displacement component, expression mouse 102 is to operate on the desktop of the abundant material of reflection ray, and optical sensor 110 accurately sensing lateral optical displacement component to react the transversal displacement amount of mouse 102.Yet, micro-control unit 108 may because of mouse 102 laterally move closer to the uniform motion, and the transverse acceleration that can't sense according to transverse acceleration sensing cell 106a is effectively changed out accurate transversal displacement component; Micro-control unit 108 is preferable transversal displacement amount with the lateral optical displacement component, and with this preferable transversal displacement amount as horizontal mouse displacement signal.
When lateral optical displacement component during less than transverse acceleration sensed displacement component, expression this moment, mouse 102 operated on the desktop of the material that is unfavorable for the light reflection, optical sensor 110 can't be on the desktop of this moment sensing lateral optical displacement component react the transversal displacement amount of mouse 102; This moment, micro-control unit 108 was preferable transversal displacement amount with transverse acceleration sensed displacement component, and with this preferable transversal displacement amount as horizontal mouse displacement signal.
Though present embodiment only explains according to the example that is operating as that lateral optical displacement component and transverse acceleration sensed displacement component produce horizontal mouse displacement signal with micro-control unit 108, right micro-control unit 108 can be analogized according to this according to the operation that vertically optical displacement component and longitudinal acceleration sensed displacement component produce vertical mouse displacement signal.
Please refer to Fig. 2, it shows the process flow diagram of displacement amount compensation process of the micro-control unit 108 of Fig. 1.Be to be that example explains according to the displacement amount compensation process that transverse acceleration sensed displacement component and lateral optical displacement component obtain horizontal mouse displacement signal among Fig. 2 with micro-control unit 108.
At first, as step 202, the transversal displacement amount of sensing mouse 102 is to provide lateral optical displacement component and transverse acceleration sensed displacement component.Then,, judge whether the lateral optical displacement component equals transverse acceleration sensed displacement component as step 204, if, execution in step 206, with one of lateral optical displacement component and transverse acceleration sensed displacement component as horizontal mouse displacement signal.Then, execution in step 208 is exported horizontal mouse displacement signal, and finishes the operation steps of the displacement amount compensation process of present embodiment.In step 204, if not, execution in step 210, judge whether the lateral optical displacement component has identical direction with transverse acceleration sensed displacement component, if not, execution in step 212, as horizontal mouse displacement signal, follow execution in step 208 with transverse acceleration sensed displacement component; If, execution in step 214, whether the displacement of judging the lateral optical displacement component greater than the displacement of transverse acceleration sensed displacement component, if not, execution in step 212, then execution in step 208; If, execution in step 216, with the lateral optical displacement component as horizontal mouse displacement signal.Then, follow execution in step 208.
Though present embodiment is that example explains with micro-control unit 108 according to the displacement amount compensation process that transverse acceleration sensed displacement component and lateral optical displacement component obtain horizontal mouse displacement signal only, so, displacement amount compensation process can the rest may be inferred according to horizontal displacement amount compensation process longitudinally.Then, micro-control unit 108 laterally reaches vertical mouse displacement signal generation mouse displacement signal SMD according to resulting, and mouse displacement signal SMD is inputed to computing machine.So, computing machine can make cursor to be positioned at more accurately on the set goal position according to the cursor that is come by the mouse displacement signal SMD that preferably laterally reaches vertical mouse displacement signal generation on the moving screen.
(Light EmittingDiode, LED) device when being unfavorable for the desktop of light reflection to operate in material in mouse 102, remind the user to change the operation desktop of mouse 102 also for example to have light emitting diode on the housing of present embodiment mouse 102.And the mouse 102 of present embodiment also can remind user's mouse 102 to operate in the desktop that material is unfavorable for the light reflection via the display of computing machine, to change the operation desktop of mouse 102.And the mouse 102 of present embodiment also comprises a button controller 112, is coupled to microcontroller 108, with left button (not shown), right button (not shown) and the roller key (not shown) of mouse beacon 102.
The mouse of present embodiment has and quickens rule and optical sensor, with sensing respectively and export the acceleration and the optical displacement gauge of mouse.The mouse degree of will speed up of present embodiment is converted to the acceleration sensing displacement, with relatively degree of will speed up sensed displacement amount and optics sensed displacement amount, judges whether mouse operates in the bad desktop of desktop quality; The mouse of present embodiment also is used as the displacement signal output of mouse with the acceleration sensing displacement when the desktop quality is bad.The mouse of present embodiment like this can improve conventional mouse effectively can not operate in the shortcoming that some material is unfavorable for the desktop of light reflection, can operate in the desktop that material is unfavorable for the light reflection and have, and has the advantage that can detect the desktop quality simultaneously.
