"Haptic Canvas" enables users to blend, draw and feel fascinating haptic sensations with their hand within the pool filled with dilatant fluid which is made from water and starch. The unique point of the system is the functional glove which presents variable sensations. We proposed sucking/ejecting and filtering functions which cause change in the state of the fluid and attached them to each fingertip. The device can present "stickiness", "hardness" and "roughness" sensations called "haptic primary colors" according to the activating parameters. A new haptic sensation will be created when haptic primary colors are synthesized at varying rates.
