CAPACITIVE TOUCHPAD OF MULTIPLE OPERATIONAL MODES
First Claim
Patent Images
1. A capacitive touchpad comprising:
- a first pattern defined as a mode switch to switch the capacitive touchpad between a plurality of operational modes including at least a key input mode, a mouse control mode, and a handwriting input mode;
a plurality of second patterns defined in a manner corresponding to each of the operational modes; and
a panel for receiving touch input and being defined with a plurality of regions in a manner corresponding to each of the operational modes and its corresponding second patterns;
wherein an input trace from the handwriting input mode is recognized by a recognition module, and the recognition module automatically detects completion of the input trace based on subsequent occurrence of a response time initiated upon a cessation of the input trace.

Abstract
A capacitive touchpad provides multiple operational modes including at least a key input mode, a handwriting input mode, and a mouse control mode. To switch the capacitive touchpad between the operational modes, a first pattern is defined as a mode switch for users to touch thereon. For each operational mode, specific second patterns are defined for indication of their corresponding functions, and several regions are defined corresponding to the positions of the second patterns to receive touch input from the second patterns.
