1. A portable electronic device comprising:
- an annular region having both touch sensing and display functionality;
a central region inside the annular region having both touch sensing and display functionality, the annular and central regions coupled to first communication lines; and
a movable touch-sensitive element located along a periphery of the annular region and surrounding the annular region, the movable touch-sensitive element configured for detecting lateral movement of an object along the device and coupled to second communication lines different from the first communication lines;
wherein the annular region, the central region and the movable touch-sensitive element are configured for being independently actuated and generating first and second signals transmitting respectively through the first and second communication lines and corresponding to first and second distinct inputs to the electronic device.

Abstract
A touch sensing device is disclosed. The touch sensing device includes one or more multifunctional nodes each of which represents a single touch pixel. Each multifunctional node includes a touch sensor with one or more integrated I/O mechanisms. The touch sensor and integrated I/O mechanisms share the same communication lines and I/O pins of a controller during operation of the touch sensing device.
