Four pneumatic artificial muscles (approx. 2.5 mm in diameter and less than 2 g weight) were attached to each finger. They form two antagonistic pairs of muscles (i.e. flexor and extensor) and thereby enable the control of several postures of each finger independently. Implementing this structure for all five digits resulted in a hand exoskeleton with 20 DOFs for one hand. This architecture was designed similar to the human anatomy of the forearm muscle, which eventually ensured supporting a natural, unconstrained hand motion. Our system is capable of generating a pressing force of approx. 8 N as a static force and can manipulate a finger to perform high-speed tapping at approx. 10 Hz. Finally, we describe a semi-automatic fitting system that helps to attach the glove easily to the user’s body. Early investigations indicate that the basic technology of our system can contribute domains that need to provide physical force feedback and posture correction to the user’s fingers.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"13 1","pages":"217-222"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90546406","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}

A tactile sensor is used to acquire sequences of tactile images of deformable objects when different forces are applied. Hence, the sequence of data can be represented by 3D tactile tensors in a similar way to the sequences of images represented in Magnetic Resonance Imaging (MRI). However, in this case, each 2D frame represents the pressure distribution when a certain force is applied, and the third dimension represents time or the variation of the applied force. Due to this feature of data, a 3D Convolutional Neural Network (3D CNN) called TactNet3D has been created to classify tactile information from 9 deformable objects. A dataset composed of 540 tactile sequences formed by [28×50×10] tactile tensors is used to train, validate and test the performance of TactNet3D, showing that it can classify deformable objects with an accuracy of 96.39% with time series of pressure distributions.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"12 1","pages":"551-555"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90471200","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}

The device is composed of a fabric sleeve with a linear array of thermoplastic pneumatic actuators. The actuators are sequentially inflated and deflated, carefully controlling the amount of inflation of each actuator using an electronic pressure regulator. The travelling wave of pressure up the arm creates the illusion of lateral motion, even though no physical lateral motion occurs. We evaluate the device in a human-subject study to determine the optimal actuation parameters that create the most continuous and pleasant sensation. The results of the study indicate that short inflation times create a more continuous and pleasant sensation, but the pressure change during inflation does not affect continuity and pleasantness.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"43 1","pages":"193-198"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89170238","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}

We present the design of a hybrid device including both vibration and impact actuators and a physics-based rendering method for realistic collision simulation. We also report a user study carried out to comparatively assess the subjective quality of haptic collision rendering using vibration only, impact only, and multimodal (vibration + impact) stimuli.

These imbalances can be due to a variety of reasons, including people’s perception of speakers and their voice. Indeed, speakers with higher pitched voices were shown to be perceived as having lower leadership ability. In an attempt at countering such voice-pitch related biases, this work introduces BarryWhaptics, a real-time speech-to-haptics conversion system that leverages multimodal perception to alter the listener’s perception of a speaker. The system operates by augmenting human speech with vibration, applying more intense vibrations to voices that would ordinarily be considered low in dominance. Results from a pilot study assessing the influence of the system in a decision-making task demonstrate that it can meaningfully influence how users choose to follow instructions given by one speaker over another.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"63 1","pages":"365-370"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86939161","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}

While the vibration propagation usually impedes this localization, we show in this paper that narrow strip-shaped plates constitute waveguides in which bending waves below a cut-off frequency do not propagate. We provide a theoretical explanation of the phenomenon and experimental validations. We thus show that vibrations up to 2 kHz are well confined on top of the actuated area with vibration amplitude over 1 µm that can be felt by the fingers. The principle was validated with piezoelectric actuators of various shapes and a vibration motor.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"189 1","pages":"431-436"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79456207","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}

Since human feels the temperature of the air without touching other objects, it is necessary to present thermal sensation in a non-contact manner. Studies on non-contact heat display have been explored; however, few studies have reported on a device that can display cold in a non-contact manner. In this study, we propose a non-contact cold thermal display using a low-temperature heat source—vortex tube, which can generate ultra-low air temperature when supplied with compressed air. We developed a cooling model that relates the flow velocity of cold air with the absorbed heat from skin; we implemented a prototype system that can control the flow velocity of the generated air; and we conducted an experiment to examine the cold sensation that the system can present. Our results revealed that various cold sensations can be generated so that the faster the flow velocity, the colder a user would feel.","PeriodicalId":6702,"journal":{"name":"2019 IEEE World Haptics Conference (WHC)","volume":"11 1","pages":"133-138"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78426531","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}
