In this research, we present a system that can support object gestures in ubiquitous environment. We propose various techniques to use any object around users for devices and appliances interactions. These techniques make user interactions more natural and intuitive. We propose technique to use any object around users for devices and appliances interactions.

We present several innovative interaction techniques for 3D target acquisition and indication. These techniques make use of the shape of our cylindrical multi-touch interface, which we are developing as an interface for a volumetric display. Our interaction techniques are used to control a spherical cursor in 3D space. Notably, our techniques use a two-handed operation in which the position and size...
To support understanding a specific GUI functionality in a program, we propose a visualization technique that presents the correspondence between the screens before and after the operation, as well as the traces of the source code executed by the operation. The presented traces include the executed lines and the method calls, which are fundamental information for understanding the functionality. They...
