1. A method of making a multi-touch input device for a computing device, the method comprising:
- forming on one side of a flexible, insulating substrate a first set of sensor elements, the first set of sensor elements defining a plurality of rows of an array of sensor elements;
forming on the one side of the substrate a second set of sensor elements, the second set of sensor elements defining a plurality of columns of the array of sensor elements, the rows and columns together defining a plurality of pixels of the multi-touch sensor, each pixel configured to detect touch at a location on the multi-touch input device over that pixel;
forming on the one side of the substrate connectors for the first set of sensor elements;
forming on the one side of the substrate an insulating layer over the connectors for the first set of sensor elements;
forming connectors for the second set of sensor elements over the insulating layer; and
placing a piezoresistive material over the array of sensor elements to form a pressure sensor.

Abstract
Embodiments are disclosed herein that are related to input devices with curved multi-touch surfaces. For example, in one disclosed embodiment, a method of making a multi-touch input device having a curved touch-sensitive surface comprises forming on a substrate an array of sensor elements defining a plurality of pixels of the multi-touch sensor, forming the substrate into a shape that conforms to a surface of the curved geometric feature of the body of the input device, and fixing the substrate to the curved geometric feature of the body of the input device.
