Microsoft Kinect, a low-cost motion sensing device, enables users to interact with computers or game consoles naturally through gestures and spoken commands without any other peripheral equipment. As such, it has commanded intense interests in research and development on the Kinect technology. In this article, we present a comprehensive survey on Kinect(More)
In this paper, we describe the design and implementation of a Kinect-based system for rehabilitation exercises monitoring and guidance. We choose to use the Unity framework to implement our system because it enables us to use virtual reality techniques to demonstrate detailed movements to the patient, and to facilitate examination of the quality and(More)
In this paper, we describe a rule based approach to realtime motion assessment of rehabilitation exercises. We use three types of rules to define each exercise: (1) dynamic rules, with each rule specifying a sequence of monotonic segments of the moving joint or body segment, (2) static rules for stationary joints or body segments, and (3) invariance rules(More)
In this paper, we present a novel system for healthcare professionals to enhance their compliance with best practices and regulations using Microsoft Kinect sensors and smart watches while strictly protecting patient privacy. A core contribution of this study is a registration mechanism for a healthcare professional to explicitly give our system the(More)
Due to the content bundling and the dramatic increase of content size, the download performance in peer-to-peer networks has become a research focus again recently. In this paper, we propose a novel approach to improve the download performance based on the classical space-time trade-off. With the approach, a peer can speed up local downloads in peer-to-peer(More)
