Abstract
A device and method include an enclosure having a top layer with an external touch surface and an oppositely disposed back surface, a flexible substrate including a first portion affixed to the back surface, a second portion separate from the first portion, and an intermediate portion between the first second portions. An array of capacitive sensors is configured to sense objects proximate the external surface. A processor mounted to the second portion is configured to obtain signals from the sensors, determine object motion proximate the external surface using the signals, cause scrolling in response the object moving along a first axis, cause continued scrolling in response to the object lifting with a substantially non-zero speed along the first axis, and to not cause continued scrolling in response the object lifting with a substantially zero speed along the first axis.
