We developed Layered Touch Panel that expands the interaction techniques of touch panel. Layered Touch Panel has two touch panel layers, so that it is able to distinguish two touch states such as "finger on screen" and "finger above screen". With the structure, Rollover effect and Pick & Drop that are not available in normal touch panel are available in Layered Touch Panel.As the result of a usability test, 88% of test users answered that Layered Touch Panel is more usable than normal touch panel.Therefore, we consider that Layered Touch Panel is useful for the products that have touch panel.

We present a set of interaction techniques called "TouchFace" for casual videoconferencing among people in close relationships. It enables users to experience the sense of "touching" without the need for any special devices using interactions between cursors and live video images. After presenting the design guidelines underlying TouchFace, we describe a prototype following these guidelines. We conclude by presenting the results of a preliminary study.
