摘要
An electronic device has a sensor panel and a display upon which content is rendered in use. A control module controlling the sensor panel enters a whiteboard-style erase mode when specified conditions are met. The control module is configured to, in the whiteboard-style erase mode detect a first position on the sensor panel of a first point on a stylus; detect a second position on the sensor panel of a second point on the stylus, the second point being spaced from the first point; compute the location of the longitudinal axis of the stylus on the sensor panel from at least the detected first and second positions; and trigger an update of the rendered content at a location on the display related to the location of the longitudinal axis of the stylus on the sensor panel.
