In augmented reality, such health hazards should be prevented if we are to become a society that wears optical see-through head-mounted displays (OST-HMDs) on a daily basis. We present CircadianVisor, an OST display system that controls circadian performance. Our system combines an OST-HMD with a liquid crystal (LC) shutter and a spectrometer to control the circadian illuminance (CIL, biolux) of light incident on the user’s eyes. To prevent the CIL at the eyes from exceeding the threshold, correct for the displayed image based on RGB values, and adjust the transmittance of the LC visor to pass through the environment light based on spectral measurements, we build a proof-of-concept system to evaluate the feasibility of the system’s CIL control and test it with a spectrometer installed at the user’s viewpoint. The evaluation shows that the CIL at the user’s viewpoint can be kept below the threshold.","PeriodicalId":124113,"journal":{"name":"Proceedings of the Augmented Humans International Conference 2021","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121237233","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 this paper, we aim to understand the components of natural hand-eye interaction, propose an interaction technique through a proof-of-concept prototype head-mounted display, and evaluate the user experience of the prototype through a user study. In addition, we share insights emerged from the studies with suggestions for further development of interaction techniques based on combinations of hardware and software.","PeriodicalId":124113,"journal":{"name":"Proceedings of the Augmented Humans International Conference 2021","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114458886","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}

Reducing forearm muscle activity is important for pianists to prevent fatigue and injury. However, it is difficult for beginners to learn how to do so. In this paper, we propose using electrical muscle stimulation (EMS) to teach beginners how to reduce this muscle activity while playing a tremolo. Since experts use wrist rotation efficiently when playing tremolos, we apply EMS not to muscles that are relevant to moving the fingers but to the supinator muscle and the pronator teres muscle, which are involved in wrist rotation. We conducted a user study with eight beginners to investigate how the forearm muscle activity changed through intervention with the EMS support system. After practicing with EMS, the activity level of the extensor pollicis longus muscle and extensor digitorum muscle on the forearm was significantly lower, and the participants felt less fatigue when playing tremolos. The results suggest that an EMS support system can reduce target muscle activity by applying EMS to other muscles to teach how to move limbs efficiently.","PeriodicalId":124113,"journal":{"name":"Proceedings of the Augmented Humans International Conference 2021","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127261832","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}

Herein, we propose a novel approach for controlling supernumerary appendages by exploiting upper limb redundancy. We present a headphone-style visual sensing device and a recognition system to estimate shoulder movement. Through a set of user experiments, we evaluate the feasibility of our system and reveal the potential of independent control using upper limb redundancy. Our results indicate that participants are able to intentionally give commands through their shoulder motions.

This technique is widely used because of its advantages, however, it has the limitation of poor interactivity. In this study, a system in which a smartphone can be used as a POV display by mounting a rotation mechanism and installing original applications is suggested.
