CONTROL USING MOVEMENTS
First Claim

1. A method of recognising a movement of an object as one of a set of one or more possible predetermined movements, the method comprising:
- continuously or repeatedly transmitting signals between at least two transmitter-receiver pairs, said signals being reflected from said object to produce reflected signals;
recording a first event for a first one of said transmitter-receiver pairs if a said reflected signal meets a first predetermined proximity criterion;
recording a second event for a second one of said transmitter-receiver pairs if, after the first event, a subsequent reflected signal meets the first or a second predetermined proximity criterion; and
using said first and second events to identify said movement as the or one of the predetermined movements.

Abstract
A movement of an object is recognised as a predetermined movement, by transmitting signals between transmitter-receiver pairs, which are reflected from the object. A first event is recorded for one of the transmitter-receiver pairs if a reflected signal meets a predetermined proximity criterion, and a second event is recorded for a second transmitter-receiver pair if after the first event, a subsequent reflected signal meets a predetermined proximity criterion. The first and second events are used to identify the movement.

93. An apparatus for recognizing a movement of an object as one of a set of one or more possible predetermined movements, comprising:
-
at least two transmitter-receiver pairs; an electronic controller arranged to; continuously or repeatedly transmit signals between the at least two transmitter-receiver pairs, the signals being reflected from said object to produce reflected signals; record a first event for a first one of said transmitter-receiver pairs when the reflected signal meets a first predetermined proximity criterion; record a second event for a second one of said transmitter-receiver pairs when, after the first event, a subsequent reflected signal meets the first or a second predetermined proximity criterion; and an electronic processor arranged to use the first and second events to identify the movement as the or one of the predetermined movements. - View Dependent Claims (94, 95, 96, 97, 98)

99. A non-transitory computer software product configured, when executed on a computer, to recognize a movement of an object as one of a set of one or more possible predetermined movements, the software performing the method comprising:
-
receiving data resulting from continuously or repeatedly transmitting signals between at least two transmitter-receiver pairs, the signals being reflected from said object to produce reflected signals; recording a first event for a first one of said transmitter-receiver pairs if the data represents the reflected signal meeting a first predetermined proximity criterion; recording a second event for a second one of said transmitter-receiver pairs if, after the first event, the data represents a subsequent reflected signal meeting the first or a second predetermined proximity criterion; and using the first and second events to identify the movement as the or one of the predetermined movements.
