Method for using a two-dimensional touchpad to manipulate a three-dimensional image
First Claim
1. A method for manipulating a 3D image, the method comprising the steps of:
- detecting a multiple-finger linear gesture on a touchpad;
generating a signal indicative of the multiple-finger linear gesture;
determining a speed of the multiple-finger linear gesture on the touchpad; and
rotating the 3D image after the multiple-finger linear gesture for a time period proportional to the speed of the multiple-finger linear gesture;
wherein said rotating comprises rotating 3D the image around a first axis when the multiple-finger linear gesture includes a first number of fingers, and rotating the 3D image around a second axis orthogonal to the first axis when the multiple-finger linear gesture includes a second number of fingers different from the first number of fingers.

Abstract
A method manipulates a 3D image in three dimensions using two-dimensional gestures on a touchpad. The method moves the 3D image within an x-y plane in the direction of a multiple-finger linear gesture. A number of fingers used for the multiple-finger linear gesture is programmed in an instinct library associated with the touchpad. The method detects a multiple-finger linear gesture on a mutual capacitance touchpad and rotates the 3D image in the direction of the multiple-finger linear gesture about an axis in the x-y plane perpendicular to the multiple-finger linear gesture. The method also rotates the 3D image about the x-y plane in the direction of the multiple-finger linear gesture at a speed proportional to the speed of the multiple-finger linear gesture.
