Patent ID: 8913018

Claim:
A method for identifying a plurality of interactions with a digitizer sensor, the method comprising: assigning a set of values to a respective a set of entries of a relative magnitude matrix according to a set of measured values, the set of values corresponding to a respective set of junctions in the digitizer sensor, wherein a value corresponding to a junction is calculated based on relating a measured value of the junction to a reference value associated with the junction; determining an interaction threshold; a. determining a set of entries in the relative magnitude matrix having values above the interaction threshold; b. determining at least one subset of entries in the set, the subset associated with a continuous area of the digitizer sensor; c. for each of the at least one subset of entries: if the continuous area is associated with a predefined arrangement of junctions, indicating the continuous area as an interaction area; and if the continuous area is larger than a predefined size, increasing the interaction threshold by an amount and repeating steps a, b and c.
