Apparatus for controlling continuous behavior through hand and arm gestures
First Claim
1. Apparatus for sensing hand and arm gestures, the apparatus comprising:
- a. hand-held means for continuously sensing gestural parameters comprising (i) momentary pauses between oppositely directed accelerations, (ii) a tempo parameter specifying time between the pauses, and (iii) an emphasis parameter specifying a time-varying magnitude of accelerational force leading to and away from the pauses, the parameters each being expressed as a quantity;
b. means, disposed within the hand-held means, for transducing the sensed parameters into electrical signals indicative of the parameter quantities;
c. means for interpreting the signals; and
d. means for communicating the signals from the transducing means to the interpreting means.

Abstract
Apparatus for continuous sensing of hand and arm gestures comprises hand-held means for continuously sensing at least tempo and emphasis. These sensed parameters are represented quantitatively, and transduced by appropriate circuitry into electrical signals indicative of the parameter quantities. The signals may be used to control the performance of a musical composition (or the evolution of some other dynamic system), or may instead convey information. The signals may, for example, be provided to an interpreter that dynamically infers control commands from the gestures on a real-time basis in accordance with the generally accepted canon of musical conducting, directing the controlled system in accordance therewith. The invention may also sense one or more additional conducting parameters such as the speed and/or velocity, direction (i.e., trajectory) in three dimensions, absolute three-dimensional position, the "size" of a gesture in terms of the spatial distance between successive beats, and the "placement" of a beat pattern in space.
