This paper surveys more than twenty types of tactile illusions and discusses several of their aspects. These aspects include the ease with which they can be demonstrated and whether they have clear visual analogs. The paper also shows how to construct equipment made of simple supplies able to deliver well controlled tactile signals in order to conveniently demonstrate four different tactile illusions. Keywords:Tactile illusions, haptic illusions, haptic perception, tactile perception 1

This article is the first of a two-part series intended as an introduction to haptic interfaces. Together they provide a general introduction to haptic interfaces, their construction, and application design. Haptic interfaces comprise hardware and software components aiming at providing computer-controlled, programmable sensations of mechanical nature, i.e., pertaining to the sense of touch. In Part I, we describe methods that have been researched and developed to date to achieve the generation of haptic sensations, the means to construct experimental devices of modest complexity, and the software components needed to drive them. In Part II of this series, we will describe some basic concepts of haptic interaction design together with several interesting applications based on this technology.

Abstract. Physical interaction is a key aspect of pervasive games. Although physical affordances are exploited, games are missing certain kinds of feedbacks on the interface and/or interaction levels: Haptic feedback in pervasive games is still an open issue. This paper discusses feedback in pervasive games. To illustrate the ideas, our work on Haptic Airkanoid, an extension to Airkanoid, is presented. Finally, the impact of the haptic interface is discussed and our early observations are highlighted. 1

Perception is often discussed by reference to cues as separate sources of information for the perceiver [8]. With vision and audition, the list of such known cues is quite extensive [5, 11]. For example, visual

As human beings, we can interact with our environment through the sense of touch, which helps us to build an understanding of objects and events. The implications of touch for cognition are recognized by many educators who advocate the use of “hands-on ” instruction. But is it possible to know something more completely by touching it? Does touch promote the construction of more connected and meaningful understandings? Current technology makes the addition of touch to computer-generated environments possible, but the educational implications of this innovation are still largely unknown. This article is a baseline review that examines the role of touch in cognition and learning and explores the research investigating the efficacy of the haptic augmentation of instruction.

The real-time haptic interaction with deformable objects is an important area of research with wide range of applications in medicine and industry. Here, the development of computer-based medical training systems (medical simulators) is perhaps the most challenging
