Earlier studies have investigated the effect of in-site masking on tactile perception of electrovibration. In this study, we investigated whether it is possible to change the detection threshold of electrovibration at fingertip of index finger via remote masking, i.e. by applying a (mechanical) vibrotactile stimulus on the proximal phalanx of the same finger. The masking stimuli were generated by a voice coil (Haptuator). For eight participants, we first measured the detection thresholds for electrovibration at the fingertip and for vibrotactile stimuli at the proximal phalanx. Then, the vibrations on the skin were measured at four different locations on the index finger of subjects to investigate how the mechanical masking stimulus propagated as the masking level was varied. Finally, electrovibration thresholds were measured in the presence of vibrotactile masking stimuli. Our results show that vibrotactile masking stimuli generated sub-threshold vibrations around fingertip and, hence, probably did not mechanically interfere with the electrovibration stimulus. However, there was a clear psychophysical masking effect due to central neural processes. Electrovibration absolute threshold increased approximately 0.19 dB for each dB increase in the masking level.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"118 1","pages":"229-234"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75771484","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}

As one of the approaches, stiff springs can be rendered by adding virtual damping in an impedance controlled haptic interface. In this paper, we study the effect of incorporation of virtual mass on maximum renderable stiffness of a bilateral wall. The haptic interface is analyzed as a discrete time state-space system using exact discretization technique. Analytical stability boundary is obtained by solving for the roots of the characteristics polynomial. The main result of the paper shows that the maximum stiffness is rendered when the mass feedback is close to the mass of the device. For the devices with low inertia this means, at low frequencies, a high stiffness can be stably rendered with little compromise on the transparency of the system. Experiments performed on a single degree of freedom haptic interface validate the analytical results. The uncoupled stability of the interface is verified for the response of the device for initial displacement condition. The accuracy of displayed stiffness is validated when the user interacts with the wall. This further ensures the coupled stability of the device for the performed experiments. We show that the maximum stiffness achieved with virtual mass is about 2.5 times higher than that can be achieved with virtual damping.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"6 1","pages":"211-216"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74986429","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}

TDPA is an effective method to guarantee stable teleoperation in the presence of communication delay. As the TDPA has gained increasing attention, several studies have focused on extending the originally proposed one-degree-of-freedom (1-Dof) TDPA to multi-Dof. In this paper, we describe that the existing multi-Dof TDPA introduces additional distortions which do not appear in the 1-Dof TDPA. More specifically, motion in one direction can cause distortion (force fluctuation and position drift) even perpendicular to the motion. We name this phenomenon cross-dimensional artifact (CDA). The CDA leads to disturbed teleoperation control and degraded user experience. To address this issue, we first offer a deep analysis of this CDA. Then, we propose a projection-based multi-Dof TDPA extension and suggest a corresponding adaptation to eliminate the CDA. Subjective experiments show that the proposed adaptation is able to remove the distortions caused by the CDA and improve the user experience for sliding tasks and perceiving object surface features.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"29 1","pages":"223-228"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81245714","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}

Such changes can take the form of decreases in sensitivity and/or aftereffects. Aftereffects often result in a rebound in the perception of the associated stimulus property when presented with a novel stimulus. The current study sought to determine if such perceptual aftereffects could be experienced following tactile stimulation at a particular frequency. To this end, participants’ perception of a 5 Hz standard frequency stimulus was evaluated using an adaptive staircase psychophysical paradigm. Participants’ perception of the standard stimulus frequency was tested a second time following the adaptation to another stimulus frequency that was either lower (i.e., 2 Hz), the same (i.e., 5 Hz), or higher (i.e., 8 Hz) than the standard stimulus (i.e., 3 groups). Following adaptation, participants who received the 5 Hz or 8 Hz stimulation reported significantly lower estimates of the standard stimulus frequency relative to the 2 Hz group. Thus, the current work provides preliminary evidence that directional after-effects can be induced when the adapting stimulus is of equal or greater frequency relative to the test stimulus, but no such influence is observed when the adapting stimulus is less than the standard stimulus.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"31 1","pages":"295-300"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83096938","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}
