“…Research has shown that when the weight of the haptic device on fingers exceeds certain amount, it will deteriorate touch sensation [8]. The pneumatic system does not have this problem since the actuators are placed on the arm, which is less sensitive to weight.…”

“…Commercially available wearable haptic devices such as Cybergrasp TM have minimal constraints on the user's motion, but they cost thousands of dollars. Other wearable haptic devices such as the Gravity Grabber [7] provide tactile feedback to each fingertip, but their weight on fingertips can result in fatigue and negatively influence the user's touch perception [8]. There should be minimal weight on the user's hand, and pneumatic haptic gloves solve the problem.…”

We present a novel, low-power and untethered pneumatic haptic device, namely the ACTIVE-Hand, for realistic and realtime 3D gaming experience. Currently, body-motion based 3D gaming systems primarily use visual feedback to provide partly immersive gaming experiences. Tactile feedback systems in Virtual Reality provide immersion with high tactile resolution, but they are expensive and difficult to setup and calibrate. The conceptually economical modular design of the ACTIVE-Hand allows easily configurable tactile feedback as per application requirements. Contrary to commercial systems like Wii TM which provide global vibrations as a proxy for synthetic tactile feedback, the ACTIVE Hand is comparably lightweight, yet scalable to meet localized tactile resolution requirements. The ACTIVEHand provides controllable pulses for dynamic virtual interactions such as pressing virtual buttons and hitting moving virtual balls. We successfully demonstrate the paradigm of dynamic tactile interactions in virtual environments through a 3D Pong game by integrating the ACTIVE-Hand with Kinect TM camera.

“…A ring is a reasonable shape to use to ground the reaction force. There are relevant studies on the development of tactile devices employing a ring shape to achieve high wearability [38], [39], [40], [41]. However, these devices are not currently applicable to surgical situations because of the disadvantages related to the use of electrical elements.…”

We aim to achieve intraoperative localization of an early-stage gastric tumor that cannot be visually detected during laparoscopic surgery. In this study, we developed and evaluated a pneumatic tactile ring, which is a clinically applicable tactile device to provide instantaneous feedback from a tactile sensor directly manipulated by a surgeon. It was designed to be worn on the finger of the manipulating hand and to present pressure to the finger pad. It is lightweight, cost-effective, disposable, and sterilizable. We also developed a compact pneumatic drive unit to control the pressure and investigated its fundamental performance. The bandwidth of the pressure control was at least 1.3 Hz with a controllable range of up to 79.7 kPa. Moreover, a psychophysical experiment was performed to obtain the Weber ratio of the pressure and evaluate the effectiveness of the instantaneous tactile feedback of the sensor output through the tactile ring. The Weber ratio was 0.40 at the reference pressure of 22.7 kPa. The provided tactile feedback significantly reduced the absolute localization error and increased participants' confidence in their answers. It was shown that the tactile feedback through the ring is effective in laparoscopic tumor localization.

“…Considering the strength-mass and power-mass ratios of existing materials and actuators, fingertip devices are an interesting solution compared to exoskeletons [28]. Aoki et al developed a fingertip-mounted haptic device to provide contact for cutaneous sensation using wires for mixed-reality environments [33]. For example, Gosselin et al proposed a wearable haptic interface developed for precise finger interaction within virtual reality applications in large environments [32].…”
