    Pictan: interacting through free-hand images



    Pictan is a digital device which allows users to communicate purely with free-hand images. Hand-drawn images are very rich as a medium. Needless to say, a hand-writing of a person shows not only textual information but also his or her personality, and graphics can carry even more. Unfortunately, a large portion of the expressions evaporate in digital mediums, where quantification of analog data has been the main concept heretofore.
