“…Unlike electrotactile feedback, electrovibration creates a tactile sensation indirectly through electrostatic attraction forces [4] or through reverse electrovibration for which a weak electrical signal is directly injected into the user's body [5]. Electrovibration can be perceived only when the user slides the finger over the surface.…”

“…Unlike other technologies that inject electrical signals into the user's body [5] or that charge the user [26], SPARKLE does not equip users with a signal generator or with a high voltage DC charger. Users do not need to be directly linked to ground [5,26], nor charged and discharged [26] to perceive a sensation.…”

Many finger sensing input devices now support proximity input, enabling users to perform in-air gestures. While nearsurface interactions increase the input vocabulary, they lack tactile feedback, making it hard for users to perform gestures or to know when the interaction takes place. Sparkle stimulates the fingertip with touchable electric arcs above a hover sensing device to give users in-air tactile or thermal feedback, sharper and more feelable than acoustic mid-air haptic devices. We present the design of a high voltage resonant transformer with a low-loss soft ferrite core and self-tuning driver circuit, with which we create electric arcs 6 mm in length, and combine this technology with infrared proximity sensing in two proof-of-concept devices with form factor and functionality similar to a button and a touchpad. We provide design guidelines for Sparkle devices and examples of stimuli in application scenarios, and report the results of a user study on the perceived sensations. Sparkle is the first step towards providing a new type of hover feedback, and it does not require users to wear tactile stimulators.

This workshop provides a forum for discussing emerging trends in interactive surfaces that leverage alternative display types and form factors to enable more expressive interaction with information. The goal of the workshop is to push the current discussion forward towards a synthesis of emerging visualization and interaction concepts in the area of improvised, minimal, curved and malleable interactive surfaces. By doing so, we aim to generate an agenda for future research and development in interactive surfaces.
