“…The layer of glove on the skin reduces the ability of the touch receptors to correctly detect the stimuli, thereby causing an error in the delivery of the neural message (Drabek et al., 2013). Previous investigations have examined the thickness of protective gloves as a marker of touch sensitivity (Han et al., 2013; Tiefenthaler et al., 2006; Zamani & Culbertson, 2019). In fact, touch sensitivity has been shown to increase with the use of extra thin gloves although this was associated with increased puncture rates and costs (Kopka et al., 2005).…”

Background Medical gloves play a very important role in protecting health care workers and patients. It is very important to pay attention to the safety and ergonomic properties of medical gloves in their protective function. Aim To develop a quantitative tool for evaluating the safety and ergonomic properties of the medical gloves. Methods Five hospitals with a total of 185 health care workers participated in the research. The domains and items of the tool were developed based on an expert's panel, interviews with health care workers and a literature review. Face, content and construct validity was used for validation. Reliability was also evaluated using internal consistency. Results The final tool included 26 items in six domains, including tactile sensation, dexterity, grip strength, fitting, reliability and hand hygiene. The Cronbach's alpha was 0.82 for the total scale. Conclusion The final tool had good validity and reliability. The findings of this study led to the development of a comprehensive standard tool that can be used to assess the ergonomic and safety status of medical gloves. Implications for Nursing Management With this tool, problems related to medical gloves can be identified among nurses, and the necessary interventions can be predicted.

“…Participants were instructed to tap on each stimulus for about 10 seconds while keeping the stylus vertical. We did not limit how they hold the tool to have a variety of grasping styles, since different contact location of stylus with hand influences the perceptual threshold of tactile information [47]. They were allowed to switch back and forth between the two stiffnesses using the keyboard as many times as they wanted before giving their response.…”

Rendering stable hard surfaces is an important problem in haptics for many tasks, including training simulators for orthopedic surgery or dentistry. Current impedance devices cannot provide enough force and stiffness to render a wall, and the high friction and inertia of admittance devices make it difficult to render free space. We propose to address these limitations by combining haptic augmented reality, untethered haptic interaction, and an encountered-type haptic display. We attach a plate with the desired hardness on the kinesthetic device's end-effector, which the user interacts with using an untethered stylus. This method allows us to directly change the hardness of the end-effector based on the rendered object. In this paper, we evaluate how changing the hardness of the end-effector can mask the device's stiffness and affect the user's perception. The results of our human subject experiment indicate that when the end-effector is made of a hard material, it is difficult for users to perceive when the underlying stiffness being rendered by the device is changed, but this stiffness change is easy to distinguish while the end-effector is made of a soft material. These results show promise for our approach in avoiding the limitations of haptic devices when rendering hard surfaces.

“…Previous studies have also shown that wearing medical gloves impairs dexterity and tactile sensitivity during medical tasks such as determining pulse location [7]. Perception of vibration magnitude is mostly preserved during the use of a probing tool, though acuity depends on how the tool is held in the hand [16]. The size of the probe also impacts the tactile perception of vibration, which points to a role of the skin area in contact [14]; this process is probably mediated by the specific receptive fields of the tactile afferents [1].…”

With the aim of creating wearable haptic interfaces that allow the performance of everyday tasks, we explore how differently designed fingertip wearables change the sensory threshold for tactile roughness perception. Study participants performed the same two-alternative forced-choice roughness task with a bare finger and wearing three flexible fingertip covers: two with a square opening (64 and 36 mm$$^2$$ 2 , respectively) and the third with no opening. The results showed that adding the large opening improved the 75% JND by a factor of 2 times compared to the fully covered finger: the higher the skin-surface contact area, the better the roughness perception. Overall, the results show that even partial skin-surface contact through a fingertip wearable improves roughness perception, which opens design opportunities for haptic wearables that preserve natural touch.
