Pointing system for pen-based computer
First Claim
1. A computer system, comprising:
- a housing;
a processor within the housing;
a display screen attached to the housing in which the display screen is sensitive to input of a stylus; and
an input device being at least partially disposed on a housing surface opposite of the display screen, the input device being responsive to movement of a finger of a user for controlling a graphical user interface configured to operate with the processor.

Abstract
A secondary input system for a pen-based computer allows users to control a graphical user interface without the use of a stylus. The secondary input system may me in the form of a pointing system. A display surface may be attached to a housing in which the display surface is sensitive to input of a pen device. The pointing system includes a secondary input system on housing in which the input device is responsive to movement of a finger of a user for controlling the graphical user interface. The input device may be a point stick device, a touchpad, or other device that provides two-dimensional movement of a graphical object on the display surface. The secondary input system may be automatically activated or deactivated based on proximity sensing of a stylus or pen with respect of the display surface.

29. A portable computer system, comprising:
-
a processor;
a display screen being sensitive to a control implement being movable, said control implement having a communicating end for the display screen;
a user input device mounted to the housing, the user input device being controllable with a finger of a user for controlling a graphical object for the display screen; and
a memory configured to store computer executable instructions, wherein said instructions cause the computing device to perform the following steps;
sensing the communicating end of the control implement within a threshold range from the display screen; and
responsive to said sensing, deactivating the user input device. - View Dependent Claims (30, 31, 32, 33, 34, 35)

36. A portable computer system, comprising:
-
a processor;
a display screen being sensitive to a control implement being movable, said control implement having a communicating end for the display screen;
a user input device mounted to the housing operable with a finger of a user for controlling a graphical user interface; and
a memory configured to store computer executable instructions, wherein said instructions cause the computing device to perform the following steps;
sensing the communicating end of the control implement within a threshold distance from the display screen; and
responsive to said step of sensing, activating the user input device.
