Abstract

The invention consists of a device to give command signals to an electronic device characterised by being comprised of at least one acoustic sensor (2a and 2b), to be brought in contact with one or more extremities of a user by means of one or more attachments (1a and 1b), for detecting signals generated in the tissues of the user'"'"'s extremities as these move, the sensor(s) (2a and 2b) being arranged to communicate with at least one signal filtering device (13a and 13b) set up to communicate with the electronic device.

Claims

1. A device to give command signals to an electronic device characterised by being comprised of at least one acoustic sensor (2a), to be brought in contact with one or more extremities by means of one or more attachments (1a), for detecting signals generated in the tissues of the user'"'"'s extremities as the extremities move, the sensor (2a) being arranged to communicate with a processor unit (4), and the processor unit (4) being arranged to communicate with a memory (5) in which at least one signal characteristic comprising frequency and/or amplitude data is saved, the processor unit (4) being arranged to analyse the signals detected by the sensor (2a) with respect to the correlation with the signal characteristic, in which case a substantial positive correlation results in the generation of the above mentioned command signals.

3. A device according to claim 1 characterised by the command signals representing single or combined finger movements.

4. A device according to claim 1 characterised by the command signals representing the same types of signals as those sent by other types of input devices used in conjunction with electronic devices.

5. A device according to claim 1 characterised by the sensor (2a) being made of piezoelectric material.

6. A device according to claim 5 characterised by the sensor being made of a sectioned piezoelectric film.

7. A device according to claim 1 characterised by the attachment (1a) being a bracelet arranged so that acoustic signals originating in the user'"'"'s extremities can be detected with the sensor (2a).

8. A device according to claim 1 characterised by the movements to be detected being hand-, finger-or toe movements.

9. A device according to claim 1 characterised by the sensor being arranged to detect acoustic signals originating from movements of the tendons embedded in the tissues of the extremities.

10. A device according to claim 1 characterised by the sensor (2a) being arranged to detect acoustic signals originating from movements of the muscles embedded in the tissues of the extremities.

11. A device according to claim 1 characterised by the sensor (2a) being arranged to detect acoustic signals originating in the joints of the hands of a user.

12. A device according to claim 1 characterised by the means of presentation being arranged for both feedback to the user and as output interface for the processor unit 4 or connected electronic devices.

2. A device to give command signals to an electronic device characterised by being comprised of at least one acoustic sensor (2a), to be brought in contact with one or more extremities of a user by means of one or more attachments (1a), for detecting signals generated in the tissues of the user'"'"'s extremities as these move, the sensor (2a) being arranged to communicate with at least one signal filtering device (13a) set up to communicate with the electronic device.
