Persons with ASD often have deficits in hand-eye coordination, which makes many activities of daily living difficult. A VR game that trains hand-eye coordination could help users with ASD improve their quality of life. Moreover, incorporating users' interests into the game could be a good way to build a motivating game for users with ASD. We propose a Customizable Virtual Human (CVH) which enables users with ASD to easily customize a virtual human and then interact with the CVH in a 3D task. Specifically, we investigated the effects of CVHs with a VR hand-eye coordination training game - Imagination Soccer - and conducted a user study on adolescents with high functioning ASD. We compared the differences of participants' 3D interaction performances, game performances and user experiences (i.e. presence, involvement, and flow) under CVH and Non-customizable Virtual Human (NCVH) conditions. The results indicate that CVHs could effectively improve performance in 3D interaction tasks (i.e., blocking a soccer ball) for users with ASD, motivate them to play the game more, and offer a better user experience.","PeriodicalId":231501,"journal":{"name":"2015 IEEE Virtual Reality (VR)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131920358","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}

Coupled-clay consists of two network-connected workspaces, the Physical Interaction Space and the Virtual Interaction Space. The physical interaction space allows a user to directly manipulate a physical object whose shape and position are precisely tracked. This tracked 3D information is transferred to the virtual interaction space in real time. The virtual interaction space is made of an interactive multi-user stereoscopic 3D tabletop, or other 3D displays with adequate interaction device. The users at the virtual interaction space observe the virtual 3D object which corresponds to the physical object and manipulate its geometrical attributes (e.g., translation, rotation and scaling). Additionally, they can control the graphical attributes of the virtual object such as color and texture. Information about changes in geometrical and graphical attributes are sent back to the physical interaction space in real time and reflected to the object in the physical interaction space by a robotic arm and a top-mounted projector. Coupled-clay can be used to remotely collaborate on 3D modeling tasks such as between a skilled designer and novice learners. This paper details our Coupled-clay implementation and presents its interaction capabilities.","PeriodicalId":231501,"journal":{"name":"2015 IEEE Virtual Reality (VR)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131558055","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 paper details three studies investigating the effects of visual display properties and gain presentation mode on the perceived naturalness of virtual walking speeds: The first study compared three different degrees of peripheral occlusion; the second study compared three different degrees of perceptual distortion produced by varying the geometric field of view (GFOV); and the third study compared three different ways of presenting visual gains. All three studies compared treadmill walking and WIP locomotion. The first study revealed no significant main effects of peripheral occlusion. The second study revealed a significant main effect of GFOV, suggesting that the GFOV size may be inversely proportional to the degree of underestimation of the visual speed. The third study found a significant main effect of gain presentation mode. Allowing participants to interactively adjust the gain led to a smaller range of perceptually natural gains and this approach was significantly faster. However, the efficiency may come at the expense of confidence. Generally the lower and upper bounds of the perceptually natural speeds were higher for treadmill walking than WIP. However, not all differences were statistically significant.","PeriodicalId":231501,"journal":{"name":"2015 IEEE Virtual Reality (VR)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134191844","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}
