Above described driver module processing information data realize as follows:
At first carry out system initialization;
Second step was that the volume coordinate vector is set;
The 3rd step was to carry out track according to sampled data to calculate;
At last, bit-mapped on-screen track.
Above described driver module processing information data realize as follows:
At first carry out system initialization, the definition global variable, the user is delivered to driver by the parameter of UI Preferences and the parameter of MousePen in this step, its dependent variable that initialization is simultaneously used in driver;
Extract sampled data then;
The 3rd step: judge whether attitude defines,, then utilize static gap to determine attitude if attitude is undefined; Attitude is the three axle clamp angle informations of MousePen with respect to gravity direction, this on acceleration transducer be determine, as can be known.
Judge that then whether the space plane coordinate vector is determined, if do not determine, then utilizes sampled data to determine the space plane coordinate vector;
Carry out track then and calculate, the control cursor moves.Track calculates and promptly to utilize equation of motion displacement calculating vector, quantizes according to precision after being mapped to coordinate vector, is converted into the screen displacement
Realize the MousePen of said method, comprise an acceleration sensor module, a wireless sending module, a wireless receiving module and a driver module, wherein, sensor assembly is connected by a data acquisition module with wireless sending module, wireless sending module is connected by wireless transmission with wireless receiving module, and wireless receiving module is connected, carries out communication with driver module by computer interface.
