EEM202A: Capacitive Touch Sensing Over a Swept Frequency for Media Interfacing in a Car
By Nathan Pilbrough and Priscilla Cheng
Using Swept Frequency Capacitive Sensing (SFCS), a technology first developed by Disney Research to enable touch interaction in everyday objects, we seek to add a touch interface to the steering wheel of any car to enable a driver to use natural gestures to interact with a vehicle's infotainment system. In our demonstration, we show the ability of a driver to use touch gestures to interact with his or her iPhone media player over BLE.
SFCS enables gesture distinction between actions such as one-finger touch, two-finger touch, and full grip. We will also be examining the possibility of adding pressure-sensitive gesture detection to our system.
