My research studies human touch — especially tactile illusions — and turns them into haptic interfaces. I induce thermal sensations with chemistry, make electro-tactile stimulation comfortable, and deliver warmth and cold in everyday settings, moving between psychophysical experiments and wearable hardware.
Using chemical substances to evoke thermal and tactile sensations. I induce the thermal grill illusion — a burning sensation from interleaved warm and cold — chemically rather than with thermal devices, and present popping sensations from sprays, linking stimulus design to perception through psychophysics.
Making electro-tactile displays comfortable and expressive. By applying anesthetic cream I suppress the itch and pain of electrical stimulation and widen its usable dynamic range, enabling stronger and clearer pressure and vibration cues.
Wearable devices that deliver warmth and cold in everyday settings. ALCool harnesses alcohol's evaporative cooling for ubiquitous cold feedback, and Enchanted Touch layers thermal and vibrotactile cues onto real objects without covering the fingerpad.
A finger-mounted device that adds thermal and vibrotactile feedback to real objects — without covering the fingerpad, preserving natural texture and dexterity.
A wristband that harnesses the evaporative cooling of alcohol to deliver a ubiquitous cold sensation — energy-efficient and free of bulky Peltier hardware.
Inducing the thermal grill illusion — a burning sensation from interleaved warm and cold — with chemical substances instead of thermal devices, and mapping stimulus arrangement to perception.
Applying anesthetic cream to suppress the itch and pain of electrical stimulation, expanding its dynamic range for stronger, clearer pressure and vibration cues.
Creating a popping / bursting sensation on the skin by mixing glue spray and cold spray — exploring material-based chemical haptics.
研究とは別に、趣味で制作したもの。その中から評価いただいたものを掲載しています。
An interactive catharsis device: put negative feelings into words, then destroy them with haptic feedback — shred, burn, or flush them away. A playful take on stress relief.
Indirect interaction with an aerial (mid-air) CGI character: you can't touch the floating image directly, so you manipulate a toio robot to "touch" it — a shared-space tactile play experience. (Unity engineer, team project.)
An experience where an HMD becomes a living creature that parasitizes your head. A band with the HMD and pneumatic balloons lets you perceive the creature's world, controls your head motion via the hanger reflex, and conveys its pulse and warmth through a speaker and Peltier device.
