MeowPlayLive

We introduce MeowPlayLive, a live streaming system that allows viewers to interact with the cat in the live stream by sending voice messages. Since messages appear as moving objects on a tablet screen perceivable by the cat, viewers can win a chance to get heard when the cat decides to tap on the objects.

ChromoFilament

We designed a thermochromic 3D filament, ChromoFilament, that displays the malleable states in three different colors according to the associated temperatures. We believe that our material-perspective approach, design process, and a series of findings could not only inspire supporting creativity through thermoforming but also heat-based processing in 3D printing.

SoundWear

This study aims to clarify the effect of non-speech sound augmentation (i.e., everyday and instrumental sounds) on outdoor play for children, where has been lacking in empirical examination. I designed SoundWear, which is a wearable device that can be worn on the wrist and allows each child to play with sounds, and a table with SoundPalette to serve as a hub of augmented play.

TouchBranch

In this paper, we present a richer understanding of it by using spatial factors and social relations among people, which has rarely been explored in interactive systems. We designed an interactive installation called "TouchBranch" where players can move light between branches placed at various distances by connecting their bodies.
