Device for pointing the cursor on the screen of interactive systems
First Claim
1. Device for pointing the cursor on the screen of interactive systems, comprising a manual actuation element which is formed by a hollow cylinder, by a button which is supported so that it can rock in said hollow cylinder, by elastic reaction means for keeping said button rested against a fixed abutment;
- said button, when pressed against said elastic reaction means in any point that is eccentric with respect to the origin of a system of orthogonal axes X and Y placed at the center of said button, being suitable to be tilted in the direction of the point where pressure is applied;
sensor means, operatively associated with said element, for providing signals that correspond to the components in the directions X and Y of the tilt that is a consequence of said pressure;
a logic controller suitable to perform a cyclic analysis of said signals and to calculate, for each cycle, an incremental movement to be applied to the cursor in the direction corresponding to the direction of the tilt and at a speed that increases as the modulus of said tilt increases;
a logic unit for accumulating the calculated movements and for transmitting the corresponding information to a system in a manner that is compatible with a normal mouse.

Abstract
A device for controlling the positioning of the cursor displayed on the screen of interactive systems includes: a manual actuation element which is similar to a button and reacts, when pressed in any eccentric point of its surface (with respect to which a system of perpendicular coordinated axes X and Y is defined), by rocking, that is to say by tilting in the direction of the point where pressure is applied (to an extent determined by ergonomic criteria together with the other shape and elastic reaction characteristics of the button); sensor means which are operatively associated with the actuation element and are suitable to provide signals corresponding to the components in the directions X and Y of the consequent inclinations; a logic controller for analyzing the signals periodically and for calculating, for each cycle, an incremental movement to be applied to the cursor in the direction corresponding to the direction of the rocking motion and at a speed that increases as the associated modulus increases; a logic unit for accumulating the calculated movements and for transmitting the corresponding information to a system in a manner that is compatible with an ordinary mouse.
