Layered protocols approach to analyze haptic communication over a network

A layered protocols interaction model to describe haptic communication between two persons over a network is presented. This approach allows to consider all aspects of the haptic communication process: the intention to do an action, limitations of the human body, the communication device, and the network. The goal of the model is threefold, firstly it is a tool to identify problems and opportunities in existing haptic interaction projects, secondly it directs to solution areas of these problems and opportunities, and thirdly it aids to propose design guidelines for new devices for haptic interaction. We show that the model can be used during the synthesis of devices. As a first step in this process, existing communication devices are being analyzed and classified. Their strong and weak points are identified and linked to signals in the model. In the future, this should result in a set of design guidelines for haptic communication devices.
