Patent ID: 6882596

Claim:
A manual control device for executing functions particularly for an electronic watch including, in a case closed by a crystal, a time-keeping circuit and/or a watch movement powered by an energy source, and at least one liquid crystal display for displaying data, said device including: a determined number of sensors wherein one touch sensitive pad of each sensor is arranged on an internal or external face of the watch crystal, each sensor being able to be activated by a user's finger placed on the crystal In a determined zone of the corresponding sensitive pad of the sensor in order to control the execution of a specific function, and an electronic circuit for processing measuring signals provided by the sensors for carrying out a specific instruction from an activated sensor, the electronic circuit providing control signals to the liquid crystal display of the watch to display data corresponding to the activated sensor, wherein in a first mode selected by the electronic circuit, at least two sensors are grouped such that they are activated together and the electronic circuit executes the same operation when a finger is placed on the crystal in a determined zone of the sensitive pad of one sensor of the other grouped sensor whereas in a second mode selected by the electronic circuit, each sensor activated by itself and by the finger provides measuring signals to the electronic circuit for executing a specific operation different for each sensor.
