Apparatuses and methods of position calculation of a touch are described. One method obtains at a processing device touch data of a sense array, the touch data represented as multiple cells. The touch data is for a touch detected proximate the sense array. Noise may be detected on the sense array based on the touch data and a position calculation algorithm from multiple different position calculation algorithms is selected based on the detected noise. The position of the touch proximate the sense array is determined from the touch data based on the selected position calculation algorithm.
