To make keys more distinguishable and to improve user-friendliness of such input devices, we have introduced mechanisms that enhance tactile feedback and provide active reactions to user's finger. So far, many of haptic devices have used motors or actuators to produce such active reactions. However, in order to make the device small, simple and reliable, we introduce mechanisms that produce the active reactions by transforming finger movement mechanically to up-down movement of sticks that stimulate fingertips. Effectiveness of these mechanisms is demonstrated by basic experiments.","PeriodicalId":117050,"journal":{"name":"First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems.

This study seeks to quantify human force control limitations in admittance control systems, where robot velocity is controlled to be proportional to the force applied by a human operator. Measurements of human force control in both admittance- and velocity-controlled scenarios were used to quantify force control precision, as well as to find a threshold over which a human cannot control a constant force and determine if that threshold depends on admittance gain or velocity. Experimental results show that robot velocity, not admittance, determines force control precision. Thus, velocities in admittance control systems should be limited to ensure that human force inputs remain precise.","PeriodicalId":117050,"journal":{"name":"First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems.

The two-degree-of-freedom mechanism was computer optimized to accommodate the workspace of the human finger inflexion/extension with a high degree of kinematic isotropy. Direct drive with frictionless flat-coil actuators ensures low torque ripple, inertia, and static friction in the actuation system for high fidelity haptic rendering. This paper describes a redesign of the position sensing arrangement, I/O hardware and software as well as thermal modelling to improve performance and stack four devices for use with index, middle, ring and little finger in a multifinger haptic display. Some results of the initial performance evaluation are given. Promising applications are expected to include palpation training for medical personnel, museum displays enabling the visitor to \"touch\" art, as well as psychophysics research: exploring the limits of human touch perception.","PeriodicalId":117050,"journal":{"name":"First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems.

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.","PeriodicalId":117050,"journal":{"name":"First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems.
