Abstract:
1. An input system for a compact electronic device comprising a primary sensor and associated interpretive and display-control circuitry, wherein: a) the sensor is actuable by a digit of a user and registers values of a planar variable, associated with the digit and modulable by the user, in an x dimension and a y dimension; and also registers values of a normal variable, associated with the digit and modulable by the user, in a z dimension normal to a plane of contact between the sensor and the digit; whereby the set of possible momentary input signals forms a three-dimensional vector region or input space, and the signal registered over an interval of time is a trajectory through this region; b) the interpretive circuitry is configured to: c) the display-control circuitry is configured to:
