In this study, we aimed to indirectly estimate the contribution of mechanoreceptors to the perception of illusory pulling torque cues by examining the relationship between vibration thresholds and the properties of these illusions, leveraging the known decline in cutaneous sensation sensitivity associated with aging (N = 40). Our results revealed an age-related increase in vibration thresholds, which is consistent with previous research. While male participants showed consistent sensitivity to illusory pulling cues across age groups, female participants exhibited a decline in sensitivity with age. Moreover, we observed only weak or no correlations between the vibration thresholds and the sensitivity of the illusory pulling cue. Although we were unable to identify any findings that explain the contribution of mechanoreceptors, we discovered a gender difference in the sensitivity to induced illusions among older individuals. These findings offer valuable insights for elucidating the mechanism underlying the illusion.</p>","PeriodicalId":13215,"journal":{"name":"IEEE Transactions on Haptics","volume":"PP ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we learn from haptic intuitions of the blind and low vision (BLV) and the Protactile DeafBlind (PT-DB) community to investigate how core functions of communication can be routed through tactile channels. We investigate this re-routing by designing the Conversational Haptic Technology (CHAT) system, a wearable haptic system to explore the feasibility of language recreation through core functions of communication and emotional expression via touch. We contribute the design evolution of an input (sensing) pad and an output (actuation) pad, which enable a bidirectional, wireless system to support remote, touch-based communication. These systems were iteratively evaluated through a series of user studies with sighted-hearing (N=20), BLV (N=4), and PT-DB (N=7) participants to uncover touch profiles for relaying specific communication functions and emotional responses.

Very rigid objects can be rendered when the prop remains static, but rotations when the users grasp the prop also allow for the simulation of soft objects.

Maintaining a human in the loop has proven to be a reliable strategy in these applications, yet there are currently limitations to the efficacy of human operators. Haptic feedback has been proposed as a method of addressing these limitations, and aiding UGV operators in safe and effective operation. This manuscript presents the experimental validation of LARIAT (Lowering Attention Requirements in semi-Autonomous Teleoperation), a portable haptic device for teleoperated semi-autonomous UGVs. This device utilizes an adapted predictive form of the Zero-Moment Point (ZMP) rollover index to inform haptic squeeze cues provided to the UGV operator for human-on-the-loop notifications. First, a brief design overview of LARIAT, implemented haptic control, and the ZMP index are presented. In addition to experimental device characterization of the just noticeable difference, we present a case study that demonstrates LARIAT's abilities to improve teleoperation performance. In an experiment involving a simulation of walking behind a semi-autonomous UGV, LARIAT reduced the number of UGV rollovers by up to 50%, with comparable or increased performance in a concurrent secondary tasks.</p>","PeriodicalId":13215,"journal":{"name":"IEEE Transactions on Haptics","volume":"PP ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143541865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While considerable effort has focused on minimizing these dynamics, we lack a robust understanding of their impact on user task performance across the range of human motor control ability. Here, we utilize a 1-DoF teleoperator testbed with interchangeable mechanical and electromechanical couplings between the leader and follower to investigate to what extent, if any, the dynamics of the teleoperator influence performance in a visual-motor pursuit tracking task. We recruited N = 30 participants to perform the task at frequencies ranging from 0.55–2.35 Hz, with the testbed configured into Mechanical, Unilateral, and Bilateral configurations. Results demonstrate that tracking performance at the follower was similar across configurations. However, participants' adjustment at the leader differed between Mechanical, Unilateral, and Bilateral configurations. In addition, participants applied different grip forces between the Mechanical and Unilateral configurations. Finally, participants' ability to compensate for coupling dynamics diminished significantly as execution speed increased. Overall, these findings support the argument that humans are capable of incorporating teleoperator dynamics into their motor control scheme and producing compensatory control strategies to account for these dynamics; however, this compensation is significantly affected by the leader-follower coupling dynamics and the speed of task execution.","PeriodicalId":13215,"journal":{"name":"IEEE Transactions on Haptics","volume":"18 1","pages":"20-31"},"PeriodicalIF":2.4,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143541869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve an ideal tactile presentation using ultrasound, the acoustic field on the user's skin surface must be determined, particularly the location of the focal point. Previous studies have suggested that thermal images can be used to immediately visualize sound pressure patterns on finger surfaces. In this study, we comprehensively investigated the performance of thermal imaging for measuring the ultrasound focus on the skin. First, we confirmed that the sound pressure peak at the focus and the temperature change peak were matched using silicone that mimicked the skin. In addition, we confirmed that when human skin was irradiated, a temperature increase was observed at above 4.0 kPa in 9 out of 10 participants. Moreover, a 5.5 kPa focus could be employed to track the focal position. if the moving velocity was less than 100 mm/s and to detect the orbit if the velocity was less than 2000 mm/s.
