ABSTRACT
As mobile and tangible devices are getting smaller and smaller it is desirable to extend the interaction area to their whole surface area. The HandSense prototype employs capacitive sensors for detecting when it is touched or held against a body part. HandSense is also able to detect in which hand the device is held, and how. The general properties of our approach were confirmed by a user study. HandSense was able to correctly classify over 80 percent of all touches, discriminating six different ways of touching the device (hold left/right, pick up left/right, pick up at top/bottom). This information can be used to implement or enhance implicit and explicit interaction with mobile phones and other tangible user interfaces. For example, graphical user interfaces can be adjusted to the user's handedness.

uTouch: sensing touch gestures on unmodified LCDs
CHI '13: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsCurrent solutions for enabling touch interaction on existing non-touch LCD screens require adding additional sensors to the interaction surface. We present uTouch, a system that detects and classifies touches and hovers without any modification to the ...
Touch & activate: adding interactivity to existing objects using active acoustic sensing
UIST '13: Proceedings of the 26th annual ACM symposium on User interface software and technologyIn this paper, we present a novel acoustic touch sensing technique called Touch & Activate. It recognizes a rich context of touches including grasp on existing objects by attaching only a vibration speaker and a piezo-electric microphone paired as a ...
Back-of-device interaction allows creating very small touch devices
CHI '09: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsIn this paper, we explore how to add pointing input capabilities to very small screen devices. On first sight, touchscreens seem to allow for particular compactness, because they integrate input and screen into the same physical space. The opposite is ...
