Abstract
The present invention relates to a method for controlling a gradient induction mouse, which is composed of a sensor chip 1 and a microprocessor 2. X-Y directional balancing induction signals X (OUT) and Y (OUT) generated by the sensor chip are transferred into the end port of a timer / a timing device of the microprocessor UP2, the balancing induction signals X (OUT) and Y (OUT) are decoded by the microprocessor, and the acceleration speed in an X direction and a Y direction can be determined; thereby, the direction and the speed of the mouse movement of a screen can be controlled so that the purpose of the mouse intelligent control can be achieved. The mouse intelligent control method proposed by the present invention uses the gravity as one input vector of a balancing inductor (sensor chip) for the gravity acceleration, and the space position of the mouse on a control panel of the movable intelligent terminal can be determined through the (solidification) software calculation. Thereby, the present invention has the characteristics of simple structure, and strong operational reliability, and is the ideal movable intelligent terminal for most computer users.
Description
Technical field
The present invention relates to computer realm, specifically a kind of mouse intelligence control method of mobile intelligent terminal.
Background technology
Present various mobile intelligent terminal, as palm PC PDA, be applied to the robot calculator field more and more widely, the input of information generally is the method that relies on button or touch-screen, and easily mouse input method owing to the requirement that does not meet the hand-held device portability can not get widespread use.If can be under the prerequisite that does not influence the mobile intelligent terminal portability, realize mouse Based Intelligent Control function, strengthen its ease for use, be undoubtedly that vast mobile intelligent terminal user dreams of.Proposition of the present invention can make this imagination be achieved.
Summary of the invention
The objective of the invention is to propose a kind of built-in balance induction installation to be replaced general external tumbling-type mouse, under the prerequisite that does not influence the mobile intelligent terminal portability, realize the mouse control function.
The present invention mainly forms (as Fig. 1) by sensor chip 1 and microprocessor 2, the X that sensor chip 1 produces, the induction signal X of the sense of equilibrium of Y direction
OUTAnd Y
OUTBe sent to timer/timer port of microprocessor μ P2, by the induction signal X of 2 pairs of sense of equilibriums of microprocessor
OUTAnd Y
OUTDecode, determine X, the acceleration on the Y both direction is controlled direction and the speed that screen mouse moves with this, thereby reaches the purpose of mouse Based Intelligent Control.ADXL202E is the two dimension acceleration sensor chip, and it can be provided at X, on the Y direction with the digital signal of the proportional working cycle of acceleration (being pulse width and the ratio in cycle) as output.A μ P can be directly imported in this working cycle output, working cycle is counted and calculated respectively X, the acceleration on the Y direction by μ P.X, the working cycle curve of typical case's output as shown in Figure 5 on the Y direction.
Wherein: the width that is in " on " state in the T1-circulation.
The width of T2-global cycle.Variation range: by 0.5ms to 10ms.
The time of working cycle-be in " on " state (T1) accounts for the ratio of global cycle (T2).
The pulse width of pulse width-be in " on " state.
Acceleration formula:
Acceleration (g)=(T1/T2-50%)/(12.5%)
Here, 0g represents 50% working cycle.Zoom factor: 12.5% working cycle/g
At X, on the Y both direction, output circuit can feed timer/timer port of a μ P to analog signal conversion for using working cycle modulated digital signal, this digital signal, and it is counted and decodes.Timer/timer is by measuring T1, the length of T2 signal and by above-mentioned formula: acceleration (g)=(T1/T2-50%)/(12.5%) calculates acceleration.Coding/decoding method has a lot, and the method that present embodiment adopts is (shown in Figure 6 as curve), and timer begins counting from the rising edge (Ta=0) of X-axis, and record negative edge (Tb), timer stop timing when X-axis rising edge (Tc) arrival next time.T1＝Tb-Ta，T2＝Tc-Ta。For Y-axis output, do to handle equally (Td, Te, Tf).
The mouse intelligence control method that the present invention proposes is with the input vector of gravity as acceleration of gravity balance induction installation (sensor chip), by (curing) computed in software, thus the locus of mouse on definite mobile intelligent terminal control panel.When the control panel of mobile intelligent terminal was parallel to the ground, acceleration transducer was the most responsive to degree of tilt.In case during the control panel run-off the straight of mobile intelligent terminal, the mouse on the control panel will roll under the effect of acceleration of gravity, the moving direction and the speed of the direction that tilts by control panel and the big or small mouse beacon of degree of tilt.When mouse enters certain selection area, can do short stay, and after the user presses ACK button, carry out " affirmation ".Also the speed that can move by the software setting mouse, function such as stop.
