However, these systems may cause undesirable perceptual interference, which has already been observed in wearable systems that simultaneously convey skin stretch and squeeze cues. To investigate this observed perceptual interference, we conducted a psychophysical evaluation of the just-noticeable difference (JND) in skin stretch and squeeze cue magnitudes independently as well as in the presence of an interfering cue. A haptic testbed delivered each cue to a user’s proximal forearm. First, the JNDs of the two haptic cues were each measured alone. Then, the cues were delivered simultaneously and the JND values for stretch with squeeze interference and squeeze with stretch interference were measured. We found that the JND for the stretch cue increased with the addition of an interference squeeze cue, while the JND for the squeeze cue did not change with interference. Results suggest that there is an interference effect between multi-sensory haptic cues that, depending on cue type, can negatively impact haptic perception. Further development of multi-sensory devices that convey salient cues has the potential to mitigate this observed interference.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"4 1","pages":"371-376"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89233732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is accomplished in three steps. First, we present a model that applies to every kinesthetic haptic display. Then, we define the Z-Qualities of a haptic display: characteristics that describe the display’s stability, sensitivity to instrumentation error, speed of changing the rendered dynamics, and accuracy of the rendered and desired dynamics. Finally, we define the Renderable Mass-Damping-Stiffness Spaces of a haptic display: the set of mass-damper-spring impedances that the display can render that satisfy specified Z-Quality constraints. We highlight existing key results for various Z-Qualities, and provide illustrative examples of renderable mass-damping-stiffness spaces for popular specified Z-Qualities ‘Passiva’ and ‘Stabila.’ This work aims to provide a framework for determining if a given haptic display can render dynamics with certain qualities, and we hope is particularly useful for psychophysical and scientific studies where accurate rendered dynamics to the human are essential.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"74 2 1","pages":"325-330"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87794452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One open problem of existing gloves is to simulate virtual objects with adjustable stiffness in a fast dynamic response, along with lightweight and good back-drivability. In this paper, we introduce a leverage pivot modulating mechanism to achieve variable stiffness simulation for force feedback gloves. To simulate free space operation, the revolute pairs of the mechanism move in the unlocked state, which allows the user to clench his/her fist or fully extend fingers. To simulate constrained space operation, the revolute pairs are locked and passive feedback forces are generated at the fingertip. The total weight of the single-finger prototype glove is 55g. Experimental results show that the backdrive force of the glove is less than 0.069N in the free space, and the fingertip force reaches up to 12.76N in the constrained space. The stiffness of the glove is tuned by changing its structural stiffness, which ranges from 136.96Nmm/rad to 3368.99Nmm/rad.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"85 1","pages":"205-210"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80916914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is caused by the magnitude and direction of the applied force on the finger pad and the elasticity of materials handled. Several past studies proposed wearable tactile systems. However, generation of distributed stimuli on a finger pad (multiple degrees of freedom stimulation) has not yet been achieved. Herein, we propose a rendering system for stimulus distribution on a finger pad. The proposed system consists of a display using multi-channel suction that presents distributed stimuli to a finger pad skin, and a real-time simulator that calculates dynamic pressure distribution on the finger pad when in contact with an elastic object. The developed display has good wearability as lightweight (5 g) and compact because it does not have an actuator on the fingertip in spite of multiple outputs (16 suction ports). We performed two different experiments using the proposed system. These experiments proved that it is possible to present different stimulus distribution depending on the contact posture between a finger and an object (experiment 1) and to present the softness of the virtual material with different elasticity values (experiment 2).","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"45 1","pages":"389-394"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90232995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
