Here, we show how to use a single actuator to generate tactile stimuli with dynamically controlled spatial extent. The method is based on the frequency-dependent damping of propagating waves in the skin. We use full-field optical vibrometry to show that vibrations introduced at the fingertip elicit waves in the finger that propagate proximally toward the hand. We show that these waves travel distances that decrease rapidly with frequency. We demonstrate the utility of these results by designing haptic effects that produce wave fields that expand or contract in size, and that can be delivered via a single actuator. In a perception experiment, subjects accurately (median >95%) identified these stimuli as expanding or contracting without prior exposure or training. These findings demonstrate how the physics of waves in the skin can be exploited for the design of spatiotemporal tactile effects that are practical and effective.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"17 1","pages":"425-430"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78256835","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}

In both applications vibration parameters need to be derived from user expectations. Users can quantify their tactile expectations by rating a compact set of familiar sensory perceptual attributes (e.g. \"tingling\", \"weak\") without prior training. These ratings could be translated into parameters of vibration eliciting the expected perceptual attributes with the help of the relationship uncovered in a previous study. But are such attributes useful for the synthesis of whole-body vibration? To answer this question audio-visual-tactile vehicle scenes were recorded and rated for their elicited perceptual attributes. Subsequently scenes with vibration synthesized from these ratings were created. In a second experiment recorded scenes and synthesized scenes were rated for their perceived plausibility. Results show that plausibility ratings are extremely similar between recorded and synthesized vibration despite clear temporal spectral differences. These findings suggest that the plausibility illusion can be produced by presenting vibration which elicit the expected perceptual attributes. Thus, tactile perceptual attributes are sufficient to quantify user expectations from which plausible vibration can be systematically designed.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"2 1","pages":"307-312"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87596957","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 representative example of this technology is ultrasound haptics, which uses ultrasonic phased arrays to deliver haptic sensations. Research on ultrasound haptics is only in its beginnings, and the literature still lacks principled perception studies in this domain. This paper presents a series of human subject experiments investigating important perceptual aspects related to the rendering of 2D shapes by an ultrasound haptic interface (the Ultrahaptics STRATOS platform). We carried out four user studies aiming at evaluating (i) the absolute detection threshold for a static focal point rendered via amplitude modulation, (ii) the absolute detection and identification thresholds for line patterns rendered via spatiotemporal modulation, (iii) the ability to discriminate different line orientations, and (iv) the ability to perceive virtual bumps and holes. These results shed light on the rendering capabilities and limitations of this novel technology for 2D shapes.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"9 1","pages":"503-508"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87134335","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 procedural requirement of using a finger holder is known to decrease the user force-detection capability at the fingertip, which could lead to poor learning outcomes. In order to increase the fingertip force-detection capabilities of the user, one possible way is to use Stochastic Resonance (SR). However, the effects of SR on a fingertip placed inside a finger holder are hitherto unknown. In this paper, first we investigate the effects of SR on the user haptic performance when the fingertip is placed inside a finger holder. Then, we propose a new haptic training method that utilizes haptic feedback and SR to improves the user performance outcomes. The results show that the user fingertip sensitivity significantly increases even when the fingertip is enclosed by a finger holder. We performed a force learning task to compare the user performance under two conditions: (i) haptic feedback with SR (proposed method), and (ii) haptic feedback without SR. The results demonstrate that the user performance, measured through task accuracy, increases with the proposed method. These findings indicate the effectiveness of the proposed haptic training method and application of SR in motor-skill learning.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"267 1","pages":"539-544"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79802786","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 crossed-hands deficit is widely considered to indicate interferences of external spatial coordinates with body-centered coordinates in the localization of touch [2]. Similar deficits have also been observed when people are only about to move their hands towards a crossed position [3]–[5], suggesting a predictive update of external spatial coordinates. Here, we extend the investigation of the dynamics of external coordinates during hand movement. Participants performed a TOJ task while they executed an uncrossing or a crossing movement, and during presentation of the TOJ stimuli the present posture of the hands was crossed, uncrossed or in-between. Present, future and past crossed-hands postures decreased performance in the TOJ task, suggesting that the update of external spatial coordinates of touch includes both predictive processes and processes that preserve the recent past. In addition, our data corroborate the flip model of crossed-hands deficits [1], and suggest that more pronounced deficits come along with higher time requirements to resolve interferences.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"23 1","pages":"145-150"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82470435","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}
