Basic study on creation of invisible shadows by using infrared lights and polarizers

This paper proposes a method for hiding information inside of an actual object and viewing the hidden information as shadows selectively by rotating the object. Our proposed system creates shadows by using the properties of the polarizing plates and the 1/2 wave-length boards. The goal of our research is to realize a novel method of information hiding.

Cloth switch: configurable touch switch wearable device made with cloth

The goal of our research is to realize a configurable wearable device made with cloth. We proposed a wearable device made with cloth as well as multiple cloth switches, each having a different function. Through our proposed system, a user can add or remove functions by simply attaching or removing relevant switches from the proposed cloth based wearable device, as well as switch functions on or off by simply touching the switches.

Japanese HCI Symposium: Emerging Japanese HCI Research Collection

This symposium showcases the latest work from Japan on interactive systems and user interfaces that address under-explored problems and demonstrate unique approaches. In addition to circulating ideas and sharing a vision of future research in human-computer interaction, this symposium aims to foster social networks among young researchers and students and create a fresh research community.

A nonluminous display using fur to represent different shades of color

This paper proposes a novel display that is in harmony with its surroundings. Our proposed display presents information using the different shades of color that can be generated in fur.

Slanting shadow: changing invisible shadow shapes by rotation for expanding shadowgraph experience

This paper proposes a method for hiding information inside an actual object and viewing the hidden information as shadows selectively by rotating the object. Our proposed system creates shadows using the properties of polarizing plates and 1/2 wavelength boards. The goal of our research is to develop a novel method for creating extended shadows.
