Abstract: An image control system for controlling a menu on a display, comprises a menu arranged as a plurality of simultaneously displayed menu items in a loop and a selector (12) to select an item from the menu, the loop and the selector being moveable with respect to each other. A user input device (4) comprises a control device (6; 16) to generate a control signal to move the loop and the selector (12) relative to each other. The control device (6; 16) has a loop configuration, with movement around the loop of the control device causing corresponding relative movement between the selector (12) and the loop of the menu. Correlation between the loop configuration of the control device and the loop of menu items enables a user to intuitively navigate around a menu of items and select a desired one.

Abstract: An enhanced touch-screen display system is disclosed for generating pixel coordinate estimates corresponding to a location on a display screen touched by a user. The system is an analog resistive touch-screen display system having a processor and associated software algorithms to allow for the calibration and validation of pixel coordinate estimates as an integral part of the real-time generation of the pixel coordinate estimates. Multiple calibrated pixel coordinate estimates are generated and processed at a pre-defined sampling rate to determine a valid pixel position to minimize sampling delays due to settling times. The x-axis position is also validated before the system attempts to generate a y-axis position to avoid the wasted time for generating y-axis estimates when x-axis estimates are corrupted. Noisy estimates are inherently reduced in the touch-screen display system by providing shunts across certain drivers in the system that also allow for detection of a “no touch” state.
