Despite powerful sensory inputs (e.g., tactile and force feedback), haptic interface systems are still in an early stage of development for accomplishment of a high degree of realism. One of the key elements missing is the ability to present thermal information, such as the thermal conductivity and temperature of an object being manipulated. This real time information is one of the obstacles to...

Haptic interfaces that present force and tactile feeling have been utilized in the areas of telemanipulation (Ivanisevi & Lumelsky, 2000; Elhajj et al., 2001), interaction with micro/nano scale phenomena (Ando et al., 2001; Marliere et al., 2004), medical training and evaluation (Langrana et al., 1994; Basdogan et al., 2001), and so on. Haptic interfaces are key devices in constructing virtual ...

This paper describes a preliminary work devoted to the design of a control architecture for a defective haptic interface, i.e. an underactuated haptic interface not able to apply forces along arbitrary directions. This interface is intended to be used for grasping tasks, where unilateral constraints are usually present. The main control problems considered in this paper concern the study of fri...

In catheter minimally invasive neuro surgery (CMINS), catheter tip collision with the blood vessel detection during the surgery practice is important. Moreover, successful CMINS is depended on the discrimination of collision by skilled surgeon in direct operation. However, in the context of teleoperated scenario, the surgeon was physically separated. Therefore, lacking of haptic sensation is a ...

This paper presents a planning of an experiment by using haptic interface for Chinese handwriting teaching. The objective of this experiment is to determine if haptic device benefits teaching Chinese handwriting. We compare two different learning methods based on different velocity of haptic device’s movement. We also try to determine if haptic devise can help to learn writing different Chinese...

Whereas the rapid growth in use of 3 dimensional computer images has proved to be of significant value to many computer users, they have remained totally inaccessible to blind people. The EU GRAB project is seeking to establish the degree to which a dual-finger haptic interface, augmented by audio input and output, can provide non-visual access to this important area of the information world. T...

We present a method for measurement of human tissue compliance in vivo using a commercial haptic interface to apply known step changes in force while recording the resulting displacements. We introduce our system, the Softcometer (SOFT-tissue COmpliance METER). Our motivation was to improve the compliance realism of our Virtual Haptic Back model, but there are many potential applications for th...
