Disambiguation of indirect input

The techniques described herein are directed to a computing device that receives data from an indirect input device. The data received may indicate or signal that one or more objects are on or within a detection area of the indirect input device. For example, the data may indicate that one or more objects are in contact with a surface of an indirect touch device. The techniques include determining parameters for the one or more objects and analyzing the parameters to determine whether the data is directed to a touch operation or to a mouse operation. To perform the touch operation or the mouse operation, the techniques further describe converting the data received from a first coordinate space of the indirect input device to a second coordinate space of a display screen.
