Haptics has been studied as a means of providing users with a natural and immersive tactile sensation in real, augmented, and virtual environments in the various areas. However, in spite of the considerable advantages offered by haptic technology, it is still relatively unfamiliar to the general public. One of reasons for this unfamiliarity is the lack of abundant haptic interaction contents, especially in areas that are very close to the general public. Even though there are a few modeling tools for creating haptic contents, addition of haptic data to graphic models or scenes is limited and many haptic modeling processes have to be done mostly manually, which is time consuming and is not intuitive. For this reason, a new, intuitive, comprehensive, and efficient haptic modeling system is needed. This paper tries to define haptic modeling processes and its scopes and proposes a basic framework for a haptic modeling system (K-HapticModeler TM ) that can create and edit haptic contents easily and intuitively for any virtual objects or graphic scenes.

This paper addresses a new design and control of a wearable 3DOF force feedback device based on wire-driven parallel mechanisms. Unlike the existing wearable force feedback devices, the proposed wire-driven device is not supported by a rigid frame attached to the upper body. All electrical components of the device are located inside a wearable jacket and the device is powered by a few batteries. The force applied to the end-effector is produced by the tension of three wires connected to it and the tension of the wires are controlled by three motors. The kinematics and workspace analysis are discussed and a simple algorithm that makes a wire maintain minimum tension while without making it slack is proposed. Also end-effector position errors caused by the flexible positions of wire extracting points are discussed. Finally, some empirical results are presented. This device may be used in some applications which need force feedback functions, especially with mobile computer devices such as mobile phones, computers and PDAs

Touch is an important part of human communication. Through handshakes, hugs and a myriad of personal gestures, we convey our emotions and express our feelings. However, how such interactions can be achieved over distance remains a relatively unexplored area of research. To begin to rectify this we present the description of a system that enables one user to reach out and touch another distant user and for both to feel the resultant physical contact. In this initial exploration, we focus on the practical feasibility of this idea, and describe the technical components required.
