Research Projects


    

Superimposing Dynamic Range

We present a simple and low-cost method of viewing static HDR content based on reflective image modulation. We project images onto hardcopies, such as photographs, X-ray prints, or electronic paper (ePaper) so as to boost contrast, perceivable tonal...

CrossOverlayDesktop

We present an intuitive interaction technique for data exchange between multiple co-located devices. In the proposed system, CrossOverlayDesktop, desktop graphics of the devices are graphically overlaid with each other (i.e., alpha-blended). Users can exchange...

Optical Superimposition of Infrared Thermography through Video Projection

This research aims to explores a novel infrared thermography visualization technique where a sequence of captured thermal images is optically and simultaneously superimposed onto the target object via video projection in real time. In conventional thermography...

Limpid Desk

Searching of spread documents on a real desk is an arduous task. The chaos on the desk makes users' searching of the desired documents difficult. In this paper, we propose "Limpid Desk" which supports a document search on a desk by transparentizing the ...

ThermoPainter

In this research, we propose, ThermoPainter, a thermal vision based area input tablet using temperature. We apply a thermal vision to the proposed system. ThermoPainter can detect temperature change regions on a sensing surface as touch regions when objects ...

Analysis of Latin and Japanese rhythmical movement

On the field of dance, Japanese people way of dancing, compared with foreigners, is known to be a bit wooden. In this research, we concentrate upon rhythmical movements because of its relevance on the field of dance. We tried to find measurable factors related to the ...

Synesthesia

This research presents an attempt at non-verbal mapping between music and images. We use physical parameters of key, height and timbre as sound, and hue, brightness and chroma as color, to clarify their direct correspondence. First we derive a mapping rule ...
