MULTI-TOUCH INPUT APPARATUS AND ITS INTERFACE METHOD USING HYBRID RESOLUTION BASED TOUCH DATA
First Claim
1. A method for mapping finger movements on a touch pad to a display screen, the method comprising:
- receiving touch data from a touch pad, the touch data identifying the absolute coordinates of one or more finger touch points on the touch pad;
providing one or more mapping modes for mapping the absolute coordinates of the one or more finger touch points to the display screen, wherein one mapping mode comprises a portion mapping mode and wherein portion mapping mode comprises;
designating a portion of the display screen as a portion mapping area, the portion mapping area being less than the entire display screen area; and
mapping the absolute coordinates of the one or more finger touch points of the touch data to corresponding coordinates of the portion mapping area; and
mapping finger movements on the touch pad to the display screen according to the one or more mapping modes.

Abstract
A method is disclosed for mapping finger movements on a touch pad to a display screen. The method includes receiving touch data from a touch pad. The touch data identifies the absolute coordinates of one or more finger touch points on the touch pad. The method also designates a portion of the display screen as a portion mapping area. The size of the portion mapping area is less than the size of the entire display screen area. The method then maps the coordinates of the one or more finger touch points of the touch data to the coordinates of the portion mapping area. The method includes use of a primary touch pad and a secondary touch pad to generate multi-touch finger gestures.

11. A method for mapping finger movements on a touch pad to a display screen, the method comprising:
-
receiving touch data from a primary touch pad, the touch data indicating the absolute coordinates of a first finger touch point on the primary touch pad; receiving touch data from a secondary touch pad, the touch data indicating the touch status of the touch pad; creating coordinates for a second, virtual touch point on the primary touch pad when the touch status of the secondary touch pad indicates that the secondary touch pad is touched; and mapping the coordinates of the first finger touch point and the second, virtual finger touch point to the display screen. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
