Measuring the Kinematics of Daily Living Movements with Motion Capture Systems in Virtual Reality Kyoungwon Seo1, Ahreum Lee1, Jieun Kim2, Hokyoung Ryu3, Hojin Choi4 1Department of Industrial Engineering, Hanyang University, 2Imagine Lab, Hanyang University, 3Department of Arts & Technology, Hanyang University, 4Department of Neurology, College of Medicine, Hanyang University We designed a virtual reality test to assess instrumental activities of daily living (IADL) with a motion capture system. We propose a detailed kinematic analysis to interpret the participant's various movements, including trajectory, moving distance, and time to completion to evaluate IADL capabilities.

Fingerstroke Time Estimates for Touchscreen-based Mobile Gaming Interaction Human Movement Science. | Pubmed ID: 26401615 The growing popularity of gaming applications and ever-faster mobile carrier networks have called attention to an intriguing issue that is closely related to command input performance. A challenging mirroring game service, which simultaneously provides game service to both PC and mobile phone users, allows them to play games against each other with very different control interfaces. Thus, for efficient mobile game design, it is essential to apply a new predictive model for measuring how potential touch input compares to the PC interfaces. The present study empirically tests the keystroke-level model (KLM) for predicting the time performance of basic interaction controls on the touch-sensitive smartphone interface (i.e., tapping, pointing, dragging, and flicking). A modified KLM, tentatively called the fingerstroke-level model (FLM), is proposed using time estimates on regression models.
