1. An electronic device comprising: a sensor configured to detect intensity of light incident on the sensor 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 signal, the estimator configured to generate one or more estimated values corresponding to an elliptical representation of data representing a gesture being associated with the intensity of light incident on the sensor, wherein the elliptical representation comprises a plurality of coefficients generated in response to the generation of the one or more estimated values, the plurality of coefficients comprising 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, and a theta coefficient representing an orientation of the ellipse within the geographic plane.
