Patent ID: 8432173

Claim:
A method comprising: receiving one or more first signals indicating one or more first capacitive couplings of an object with a sensing element that comprises a sensing path that comprises a length, the first capacitive couplings corresponding to the object coming into proximity with the sensing element at a first position along the sensing path of the sensing element determining based on one or more of the first signals the first position of the object along the sensing path; setting a parameter to an initial value based on the first position of the object along the sensing path, the initial value comprising a particular parameter value and being associated with a range of parameter values, the range of parameter values being associated with the length of the sensing path; receiving one or more second signals indicating one or more second capacitive couplings of the object with the sensing element, the second capacitive couplings corresponding to a displacement of the object along the sensing path from the first position; and determining based on one or more of the second signals the displacement of the object along the sensing path; and adjusting the parameter within the range of parameter values based on the displacement of the object along the sensing path.
