[A, D]: Tapping in this area makes a left-button mouse click
[B]: Tapping in this area makes a right-button mouse click
[C]: Move finger to this area to exit mouse function
[A, B, D]: Mouse movement area
[A, D]: Touch and hold your finger for 1 second in this area to make a
    left-button mouse pressed (vibration alert). Move your another 
    finger to have a drag action. Drop action is made once your fingers
    are off the touchpad.

TODO: Add HID USB configuration in system\core\rootdir\init.usb.rc and then we can 'setprop sys.usb.config hid' to enable HID mouse interface and automatically run test program.

Have fun. Hsinko Yu [email protected]
