A large number of HMD users watch 360-degree videos at home, often on non-swivel seats; however videos are frequently designed to require the user to turn around. This work explores how the difference in users' chair type might influence their viewing experience. A between-subject experiment was conducted with 41 participants. Three chair conditions were used: fixed, half-swivel and full-swivel. A variety of measures were explored using eye-tracking, questionnaires, tasks and semi-structured interviews. Results suggest that the fixed and half-swivel chairs discouraged exploration for certain videos compared with the full-swivel chair. Additionally, participants in the fixed chair had worse spatial awareness and greater concern about missing something for certain video than those in the full-swivel chair. No significant differences were found in terms of incidental memory, general engagement and simulator sickness among the three chair conditions. Furthermore, thematic analysis of post-experiment interviews revealed four themes regarding the restrictive chairs: physical discomfort, difficulty following moving objects, reduced orientation and guided attention. Based on the findings, practical implications, limitations and future work are discussed.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132951749","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}

Interaction techniques with gaze pointing have potential for this elementary task. There appears to be little empirical evidence concerning the benefits and drawbacks of these methods in VR. We ran an experiment studying three interaction techniques: ray casting, dwell time and gaze trigger, where gaze trigger was a combination of gaze pointing and controller selection. We studied user experience and interaction speed in a simple object selection task. The results indicated that ray casting outperforms both gaze-based methods while gaze trigger performs better than dwell time.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129528190","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}

Brain-Computer Interfaces (BCIs) could provide an alternative approach to solve these problems. However, the current BCIs have low classification accuracy and require tedious human-learning procedures. The use of complicated Electroencephalogram (EEG) caps, where many electrodes must be attached on the user's head to identify imaginary motor commands, brings a lot of inconvenience. In this demonstration, we will showcase EXGbuds, a compact, non-obtrusive, and comfortable wearable device with non-invasive biosensing technology. People can comfortably wear it for long hours without tiring. Under our developed machine learning algorithms, we can identify various eye movements and facial expressions with over 95% accuracy, such that people with motor disabilities could have a fun time to play VR games totally \"Hands-free\".","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130908764","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}

It is often used, in comics or video, in caption as a way to dramatize, emphasize, exaggerate and draw attention the situation. In this paper we explore if the use of onomatopoeia could also bring about similar effects and improve the user experience in virtual reality. We present an experiment comparing the user's subjective experiences and attentive performance in two virtual worlds, each configured in two test conditions: (1) sound feedback with no onomatopoeia and (2) sound feedback with it. Our experiment has found that the moderate and strategic use of onomatopoeia can indeed help direct user attention, offer object affordance and thereby enhance user experience and even the sense of presence and immersion.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133554979","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 addition, in the case of calorie estimation based on the amount of meal, a user conventionally needs to register a size-known reference object in advance and to take a food photo with the registered reference object. In this demo, we propose a new approach for food calorie estimation with CNN and Augmented Reality (AR)-based actual size estimation. By using Apple ARKit framework, we can measure the actual size of the meal area by acquiring the coordinates on the real world as a three-dimensional vector, we implemented this demo app. As a result, it is possible to calculate the size more accurately than in the previous method by measuring the meal area directly, the calorie estimation accuracy has improved.","PeriodicalId":138249,"journal":{"name":"Proceedings of the 24th ACM Symposium on Virtual Reality Software and Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122203648","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}
