1. A method, comprising:
- detecting an environmental effect on a touch-sensing device using a touch sensor that is unresponsive to a presence of a conductive object during the detecting;
detecting the presence of the conductive object; and
compensating for the environmental effect on the detection of the conductive object.

Abstract
A method and apparatus for detecting an environmental effect and a presence of a conductive object on a touch-sensing device without using a dedicated environmental effect sensor, and compensating for the environmental effect on the detection of the conductive object. The method may include detecting an environmental effect on a touch-sensing device using a touch sensor, detecting a presence of a conductive object, and compensating for the environmental effect on the detection of the conductive object. The apparatus may include a touch-sensing device having a touch sensor to detect an environmental effect and a processing device to compensate for the environmental effect.
