Such techniques are particularly useful when the spatial constraints are very prominent, as they are likely to be in relation to immersive gaming systems located in the homes of consumers. However, most existing WIP techniques rely on movement of the legs which may cause users, wearing a head mounted display, to unintentionally move. This paper details a within-subjects study performed with the intention of investigating how two alternative types of gestural input relying on arm and hip movements compare to the traditional WIP gesture and keyboard input. Visual feedback was delivered through a head-mounted display and auditory feedback was provided by means of a 16-channel surround sound system. The gestures were evaluated in terms of perceived naturalness, presence and real world positional drift. The results suggest that both WIP and arm swinging are perceived as significantly more natural than hip movement and the keyboard configuration. However, arm swinging better matched real walking in terms of energy expenditure and led to significantly less positional drift.","PeriodicalId":204010,"journal":{"name":"Proceedings of Motion on Games","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115538471","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}

Our method requires an animator to construct animations using a canonical set of visemes for all pairwise combinations of a reduced phoneme set (phone bigrams). These animations are then stitched together to construct the final animation, adding velocity and lip-pose constraints. This method can be applied to any character that uses the same, small set of visemes. Our method can operate efficiently in multiple languages by reusing phone bigram animations that are shared among languages, and specific word sounds can be identified and changed on a per-character basis. Our method uses no machine learning, which offers two advantages over techniques that do: 1) data can be generated for non-human characters whose faces can not be easily retargeted from a human speaker's face, and 2) the specific facial poses or shapes used for animation can be specified during the setup and rigging stage, and before the lip animation stage, thus making it suitable for game pipelines or circumstances where the speech targets poses are predetermined, such as after acquisition from an online 3D marketplace.","PeriodicalId":204010,"journal":{"name":"Proceedings of Motion on Games","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126302244","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}

Typically, motion blur computations are expensive, and for real-time applications, trade-offs are made between the quality of the effects and the computational cost. In this work, we wanted to understand: (i) the practical impact of the motion blur effect on the player experience; and (ii) whether the value gained by including the effect is worth the extra cost in computation, real-time performance, development time, etc. We studied the objective and subjective aspects of the player experience for Split Second: Velocity (Black Rock Studios, Disney), a high-speed racing game, in the presence and absence of the motion blur effect. We found that neither objective measures of participants' performance (e.g., time to complete a race) nor subjective measures of the player experience (e.g, enjoyment of a race, perceived speed) were affected, even though participants could reliably detect the presence of the motion blur effect. We conclude that motion blur effects, while useful for reducing artifacts and achieving a realistic 'look', do not significantly enhance the player experience.","PeriodicalId":204010,"journal":{"name":"Proceedings of Motion on Games","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117103359","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}
