US Patent 10013107 Data processing in relation to a multi-touch sensing apparatus

A device obtains a signal representative of objects on a touch surface of a multi-touch sensing apparatus and executes a method for extracting touch data from the signal. The method operates in a sequence of detection frames. Each detection frame comprises the steps of: obtaining the signal; processing the signal for identifying touches; determining a set of identified touches and touch data for the set of identified touches; and outputting the touch data. At least one of the steps of processing and determining includes a prioritization that actively favors certain touches to be identified and included in the set of identified touches, respectively.
