Huang, Ke, Zhang, Chunhui, Ma, Xiaoxiao and Chen, Guanling (2012): Predicting mobile application usage using contextual information. In: Proceedings of the 2012 International Conference on Uniquitous Computing 2012. pp. 1059-1065.

As the mobile applications become increasing popular, people are installing more and more Apps on their smart phones. In this paper, we answer the question whether it is feasible to predict which App the user will open. The ability for such prediction can help pre-loading the right Apps to the memory for faster execution or help floating the desired Apps to the home screen for quicker launch. We explored a variety of contextual information, such as last used App, time, location, and the user profile, to predict the user's App usage using the MDC dataset. We present three findings from our studies. First, the contextual information can be used to learn the pattern of user's App usage and to predict App usage effectively. Second, for the MDC dataset, the correlation between sequentially used Apps has a strong contribution to the prediction accuracy. Lastly, the linear model is more effective than the Bayesian model to combine all contextual information and for such predictions.

Zhao, Ji, Liu, Hujia, Zhang, Chunhui and Zhang, Zhengyou (2010): MobileSurface: interaction in the air for mobile computing. In: Proceedings of the 2010 ACM Symposium on User Interface Software and Technology 2010. pp. 459-460.

We describe a virtual interactive surface technology based on a projector-camera system connected to a mobile device. This system, named mobile surface, can project images on any free surfaces and enable interaction in the air within the projection area. The projector used in the system scans a laser beam very quickly across the projection area to produce a stable image at 60 fps. The camera-projector synchronization is applied to obtain the image of the appointed scanning line. So our system can project what is perceived as a stable image onto the display surface, while simultaneously working as a structured light 3D scanning system.

Zhang, Chunhui, Wang, Min and Harper, Richard (2010): Cloud mouse: a new way to interact with the cloud. In: Proceedings of the 2010 International Conference on Multimodal Interfaces 2010. p. 13.

In this paper we present a novel input device and associated UI metaphors for Cloud computing. Cloud computing will give users access to huge amount of data in new forms as well as anywhere and anytime, with applications ranging from Web data mining to social networks. The motivation of this work is to provide users access to cloud computing by a new personal device and to make nearby displays a personal displayer. The key points of this device are direct-point operation, grasping UI and tangible feedback. A UI metaphor for cloud computing is also introduced.
