Claim 6

The view control system of claim 1 wherein the speed in scrolling the view of the image by the computer is proportional to the force sensed by the sensing elements.

Claim 7

The view control system of claim 1 wherein the computer comprises a window software for displaying and scrolling the view of the image according to the scrolling signals and a driver program for receiving the scrolling signals from the pointing device and transmitting the scrolling signals to the window software.

Claim 8

The view control system of claim 6 wherein each of the two dimensional scrolling signals comprises two parameters representing the sensed two dimensional direction of each finger input, and the two parameters are used by the window software for scrolling the view within the image along two mutually orthogonal dimensions separately.

Claim 9

The view control system of claim 6 wherein each of the two dimensional scrolling signals comprises two parameters representing the sensed two dimensional direction of each finger input, and the two parameters are used by the window software for scrolling the view within the image along two mutually orthogonal dimensions separately; and wherein if the view is restricted to scroll within the image along only one of the two dimensions by the window software, the window software will scroll the view along said dimension according to one corresponding parameter of said dimension and ignore the other parameter.

Claim 10

The view control system of claim 1 the pointing device is connected to the computer through a flexible cable.

Claim 11

The view control system of claim 1 wherein the pointing device is a computer mouse.

Claim 12
