Cursor control with user feedback mechanism
First Claim
1. A cursor control system for controlling a cursor on a pixel display, comprising:
- a control means for generating cursor control signals and transmitting said cursor control signals to said display;
a feedback means for indicating to an operator of said cursor control device a parameter setting; and
monitoring means arranged to determine a tone level for at least a first pixel of the display overlaid by the cursor, said parameter setting indicated to the user being derived by feedback control means at least partly from the determined tone level.

Abstract
A feedback means is provided in conjunction with a cursor control mechanism for a two- or three-dimensional graphic user interface. Feedback levels are determined by tonal variation (grey scale or color component) at the pixel (P) currently indicated by the cursor. Suitably, the levels are set by generating differentials across a patch of pixels (A) surrounding the indicated pixel, with differential generation in mutually perpendicular directions (X and Y) providing for independent feedback in two or three directions. The technique enables interface features such as window boundaries (36) or textured patches to be identified to the user without specially authored software being required for those features to trigger feedback when indicated.

8. A computer system, comprising:
-
a pixel display for displaying a cursor; a host computer coupled to said pixel display; cursor control means for generating cursor control signals coupled to said host computer, said host computer receiving said cursor control signals, generating cursor display signals and sending said cursor display signals to said pixel display, and said cursor control means comprising a feedback means for indicating to an operator of said cursor control means a parameter setting; and monitoring means arranged to determine a tone level for at least a first pixel of the display overlaid by the cursor, said parameter setting indicated to the user being derived by feedback control means at least partly from the determined tone level. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
