TACTTOO – A feel-through tattoo for on-skin tactile output
Tacttoo is a feel-through interface for electro-tactile output on the user’s skin
Integrated in a temporary tattoo with a thin and conformal form factor, it can be applied on complex body geometries, including the fingertip, and is scalable to various body locations. At less than 35μm in thickness, it is the thinnest tactile interface for wearable computing to date. Our results show that Tacttoo retains the natural tactile acuity similar to bare skin while delivering high-density tactile output. Moreover, we explore new interactive scenarios that are enabled by Tacttoo. Applications in tactile augmented reality and on-skin interaction benefit from a seamless augmentation of real-world tactile cues with computer-generated stimuli. Results from two psychophysical studies and a technical evaluation demonstrate Tacttoo’s functionality, feel-through properties and durability.
