Abstract:
1. A method of processing a user input to a system comprising: receiving reflections of signals from a moving input object; repeatedly determining information relating to the direction of movement of the input object from said reflections; repeatedly determining information relating to the speed of the input object from said reflections; providing continual or continuous sensory feedback to the user, controlled by a parameter; repeatedly updating the parameter by means of an algorithm that takes, as two variable inputs, the information relating to the direction of movement of the input object, and the information relating to the speed of the input object; and applying a time-dependent change to the parameter when no new determination of information relating to the speed or direction of movement of the input object has been made since a previous update to the parameter, wherein the information relating to the direction of movement or speed of the input object is determined by applying a set of line filters to a matrix of impulse responses.
