A General Framework for Motion Sensor Based Web Services
MetadataShow full item record
With the development of motion sensing technology, motion sensor based services have been put into a wide range of applications in recent years. Demand of consuming such service on mobile devices has already emerged. However, as most motion sensors are specifically designed for some heavyweight clients such as PCs or game consoles, there are several technical challenges prohibiting motion sensor from being used by lightweight clients such as mobile devices, for example: There is no direct approach to connect the motion sensor with mobile devices. Most mobile devices don't have enough computational power to consume the motion sensor outputs. To address these problems, I have designed and implemented a framework for publishing general motion sensor functionalities as a RESTful web service that is accessible to mobile devices via HTTP connections. In the framework, a pure HTML5 based interface is delivered to the clients to ensure good accessibility, a websocket based data transferring scheme is adopted to guarantee data transferring efficiency, a server side gesture pipeline is proposed to reduce the client side computational burden and a distributed architecture is designed to make the service scalable. Finally, I conducted three experiments to evaluate the framework's compatibility, scalability and data transferring performance.
