Abstract

Current 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 display, and without adding any sensors to the user. Our approach utilizes existing signals in an LCD that are amplified when a user brings their hand near or touches the LCD's front panel. These signals are coupled onto the power lines, where they appear as electromagnetic interference (EMI) which can be sensed using a single device connected elsewhere on the power line infrastructure. We validate our approach with an 11 user, 8 LCD study, and demonstrate a real-time system.

CapWidgets: tangile widgets versus multi-touch controls on mobile devices
CHI EA '11: CHI '11 Extended Abstracts on Human Factors in Computing Systems

We present CapWidgets, passive tangible controls for capacitive touch screens. CapWidgets bring back physical controls to off-the-shelf multi-touch surfaces as found in mobile phones and tablet computers. While the user touches the widget, the surface ...
3-D interaction with a large wall display using transparent markers
AVI '10: Proceedings of the International Conference on Advanced Visual Interfaces

In this paper we proposed a new interface for interacting with large displays via small video devices such as a cell phone. We estimate the location of the camera relative to the display using a matrix of transparent markers embedded on display. As a ...
HandSense: discriminating different ways of grasping and holding a tangible user interface
TEI '09: Proceedings of the 3rd International Conference on Tangible and Embedded Interaction

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. ...
