Abstract
Technologies for detection of and response to extra-device touch events may include mobile device sensors, such as accelerometers, that detect that a touch event has taken place by detecting device movement in response to the touch event. In some embodiments, a touch event feature vector is generated from sensor readings and passed to a classifier that determines the touch event location. Other touch event information, such as timing, intensity and a profile of the object that caused the touch event can also be determined. The detecting and locating of touch events allows the interaction area of a mobile device to be extended beyond the physical bounds of the device, and allows multiple users to simultaneously use a mobile device in a more convenient manner. Applications executing on a mobile device or the device's operating system can take various actions based on the touch event's location.
