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.

A multi-functional node within a touch sensing device, the multi-functional node comprising:
- a first sensor configured for detecting a first touch input;
- and
- one or more secondary functional mechanisms integrated with the first sensor into a single physical unit, the one or more secondary functional mechanisms configured for detecting a second touch input;
- wherein the first sensor and the one or more secondary functional mechanisms are configured for communicating with a controller to perform multiple functions based on the first touch input and the second input.
