CalliJoy was a project I did for an interdisciplinary design studio course towards to my master degree of human-computer interaction in the winter of 2012, with a team of three members from industrial design, visual design and interaction design fields. I was the project manager, the interaction designer, and the technologist. The topic of this course is to design a product or service for elderly generation. CalliJoy is a system that combines calligraphy, karaoke and social interaction for senior people. A design document outlining the design process can be found below.
