Touch active area
Touch active area is an area for user to have touch input actions.
This area is built by a high sensitive capacitive touch sensor, to detect movement of user
fingers.
This device support one finger operations - such as change position, press, release, long
press, and some two finger gestures.
The design uses two layers of operation scheme, to allow function buttons exist together
with touch pad. If user presses a button longer than a designed time, the device will detect it
as a long press, and will activate the button function; otherwise, the device will recognize it
as a normal touch event, to change cursor position, or to join as part of a touch gesture
activity.
This design maximizes the use of active area for touch operations, and at the same time,
allow as many as possible soft buttons for software control purpose.

Mode changes of the device. They include power on/off, switch between cursor
mode and keyboard mode, rotate the device 90 degree to more fit into modern
TV/ display landscape view.
