Haptic human-computer interaction is interaction between a human computer user and the computer user interface based on the powerful human sense of touch. Haptic hardware has been discussed and exploited for some time, particularly in the context of computer games. However, so far, little attention has been paid to the general principles of haptic HCI and the systematic use of haptic devices for improving efficiency, effectiveness, and satisfaction in HCI.
This book is the first one to focus on haptic human-computer interaction. It is based on a workshop held in Glasgow, UK, in August / September 2000. The 22 revised full papers presented were carefully reviewed and selected from 35 submissions. Besides a brief historic survey, the book offers topical sections on haptic interfaces for blind people, collaborative haptics, psychological issues and measurement, and applications of haptics.

art exhibit consisting of a pair of spatially separated robot arms which allowed two remote users to arm wrestle with one another. Several devices have been developed on a similar theme. The shaker in Feather, Scent and Shaker [16] allowed users to shake a device in their hand and have this represented as vibration in another users coupled device. The Bed [4] attempted to create a distributed bed and used haptics to create a sensation of the remote partner breathing. inTouch, [2, 3] is a device

when the user confidently feels that he/she has learned enough to handle the robot with each interface. The average goal time of all users suggests that the hand-shaped force interface is useful in executing such task (Table 4). Afterwards, questionnaire on qualitative evaluation is held. In each category, users must rank the interfaces in order of quality. Scores are given in integers from 3 (best) to 1 (worst), and none of the scores must be repeated more than once. The result supports that the

The focus was on the mean curvature of and the variability between the paths in each direction. It can be concluded that on average cursor paths are rather straight in all eight directions and with all three devices. The variability of the paths depends on (1) direction; (2) friction of the control device; (3) user. 1 Introduction As computers

larger than for stimuli presented to the dorsal part (see Figure 3). Furthermore, the sensitivity near the sagittal plane of the torso is larger than to the sides. Moreover, the sensitivity is larger than was expected on the basis of the existing psychophysical literature on two—point thresholds (e.g., see [7], [20]). Tactile Navigation Display 169 Fig. 3.
