Abstract

Apparatuses and methods of touch location interpolation using iterative emulated touches are described. One method measures touch data on a sense array. The method determines that the touch data represents two or more touches proximate to the sense array and sequentially estimates touch geometries of the two or more touches based on two or more estimated touches that correspond to the two or more touches proximate to the sense array. The touch geometries comprise estimated touch sizes and estimated touch positions of the two or more touches. The method outputs the touch geometries of the two or more touches when an error between the two or more estimated touches and the two or more touches is less than a specified threshold.
