Abstract
A method suitable for a touch-control device having a touch-control surface for determining keys of a virtual keyboard is provided and includes: sensing positions of multiple control points on the touch-control surface to determine positions of multiple basic keys of a virtual keyboard; determining the input behavior of a user according to at least one touch behavior of at least one control point on the touch-control surface; and determining which key on the virtual keyboard is input by the user.
Claims18
A touch-control device, comprising:
- a touch-control panel, comprising a touch-control surface;
- a touch sensor, sensing a plurality of touched positions and at least one touch behavior on the touch-control surface;
- and
- a central processor, coupled to the touch sensor, processing information regarding the touched positions and the touch behavior sensed by the touch sensor,
- wherein the central processor determines positions of a plurality of control points and a plurality of basic keys of a virtual keyboard according to the touched positions sensed by the touch sensor, determines an input behavior of a user according to the touch behavior of at least one of the control points on the touch-control surface, and determines which key on the virtual keyboard is input by the user.
