Abstract:
1. 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, the one or more estimated values based upon the velocity vectors, wherein the elliptical representation of the gesture comprises a plurality of coefficients based upon the one or more velocity vectors, the plurality of coefficients comprising at least one of a center coefficient representing a center coordinate of an ellipse within a geographic plane, a first radius coefficient representing a semi-major radius value of the ellipse within the geographic plane, a second radius coefficient representing a semi-minor radius value of the ellipse within the geographic plane, or a theta coefficient representing an orientation of the ellipse within the geographic plane.
