Abstract

A method including receiving an output signal from a grid based digitizer sensor to detect outputs from junctions of the sensor, identifying, based on the output signal, an area on the sensor likely to include output caused by touch of a passive pen tip, applying a maximum likelihood cost function at points within the area to identify likely coordinates of the passive tip on the digitizer sensor, and selecting most likely coordinates for the location of the passive pen tip, wherein the most likely coordinates are defined based on the output signal in the area and on a pre-defined response function, wherein the response function relates an output signal from a junction to distance of the passive tip from the junction. Related apparatus and methods are also described.
