Moussette, Camille, Kuenen, Stoffel and Israr, Ali (2012): Designing haptics. In: Proceedings of the 6th International Conference on Tangible and Embedded Interaction 2012. pp. 351-354.

This studio proposes to tangibly explore the world of haptics to develop a greater understanding and sensitivity to this emerging field. The first part of the studio focuses on general knowledge about haptics, haptic and multimodal perception in humans, and key advances in actuator and sensor technologies to develop haptic interfaces. Numerous demos and testing platforms will be available to relate discussions with real haptic sensations. The second part of the studio aims to explore the various challenges and difficulties in designing haptic interfaces by directly building and sketching in hardware haptic interfaces. Participants will be invited to build their own haptic interfaces from various actuators, sensors and other building blocks. The studio aims to bridge the fields of haptics and design, and investigate various prototyping tools and approaches that can best support haptic design activities.

Israr, Ali and Poupyrev, Ivan (2011): Tactile brush: drawing on skin with a tactile grid display. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 2019-2028.

Tactile Brush is an algorithm that produces smooth, two-dimensional tactile moving strokes with varying frequency, intensity, velocity and direction of motion. The design of the algorithm is derived from the results of psychophysical investigations of two tactile illusions -- apparent tactile motion and phantom sensations. Combined together they allow for the design of high-density two-dimensional tactile displays using sparse vibrotactile arrays. In a series of experiments and evaluations we demonstrate that Tactile Brush is robust and can reliably generate a wide variety of moving tactile sensations for a broad range of applications.

Xu, Cheng, Israr, Ali, Poupyrev, Ivan, Bau, Olivier and Harrison, Chris (2011): Tactile display for the visually impaired using TeslaTouch. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 317-322.

TeslaTouch is a technology that provides tactile sensation to moving fingers on touch screens. Based on TeslaTouch, we have developed applications for the visually impaired to interpret and create 2D tactile information. In this paper, we demonstrate these applications, present observations from the interaction, and discuss TeslaTouch's potential in supporting communication among visually impaired individuals.

Israr, Ali and Poupyrev, Ivan (2010): Exploring surround haptics displays. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 4171-4176.

In this paper we present the design and evaluation of a two dimensional haptics display intended to be used for enhancing experience for movies and rides. The display, haptics surface, utilizes an array of vibrators contacting the skin at discrete locations and creates static and dynamic haptic sensations derived from scenes and situations. For this regard, a set of haptic morphs are introduced that can be used as building blocks to create new sensations on the skin. A novel haptic sensation, haptic blur, is also introduced that gives an illusion of continuous motion across the skin using discrete vibrating points. A pilot study investigating the reliability of haptic blur along a two dimensional skin surface is presented along with conceptual discussion on future haptic feelings rendered through the haptics surface.

Bau, Olivier, Poupyrev, Ivan, Israr, Ali and Harrison, Chris (2010): TeslaTouch: electrovibration for touch surfaces. In: Proceedings of the 2010 ACM Symposium on User Interface Software and Technology 2010. pp. 283-292.

We present a new technology for enhancing touch interfaces with tactile feedback. The proposed technology is based on the electrovibration principle, does not use any moving parts and provides a wide range of tactile feedback sensations to fingers moving across a touch surface. When combined with an interactive display and touch input, it enables the design of a wide variety of interfaces that allow the user to feel virtual elements through touch. We present the principles of operation and an implementation of the technology. We also report the results of three controlled psychophysical experiments and a subjective user evaluation that describe and characterize users' perception of this technology. We conclude with an exploration of the design space of tactile touch screens using two comparable setups, one based on electrovibration and another on mechanical vibrotactile actuation.
