Abstract
Techniques are described that may be implemented with an electronic device to detect a gesture within a field of view of a sensor and generate a compact data representation of the detected gesture. In implementations, a sensor is configured to detect a gesture and provide a signal in response thereto. An estimator, which is in communication with the sensor, is configured to generate an elliptical representation of the gesture. Multiple coefficients for the compact representation of the gesture can be used to define the ellipse representing the gesture.
Claims20
An electronic device comprising:
- a sensor configured to detect a gesture and provide a signal in response thereto;
- and
- an estimator communicatively coupled to the sensor, the estimator configured to receive the signal from the sensor and generate one or more velocity vectors based upon the gesture, the estimator configured to generate one or more estimated values corresponding to an elliptical representation of the gesture.
An system comprising:
- a sensor configured to detect a gesture based upon detecting light occurring within a limited spectrum of wavelengths and provide a signal in response thereto;
- a processor communicatively coupled to the sensor, the processor configured to receive the signal from the sensor;
- an estimator communicatively coupled to the processor, the estimator configured to generate one or more velocity vectors based upon the signal;
- and
- control programming executable on the processor and configured to generate an elliptical representation of the gesture based upon the velocity vectors.
(canceled)
A method comprising:
- receiving a signal from a sensor in response to the sensor detecting a gesture occurring within a field of view of the sensor;
- estimating one or more velocity vectors based upon the signal;
- and
- estimating one or more values based upon the velocity vectors, the one or more values corresponding to an elliptical representation of the gesture.
