Abstract: A gesture-based control method for interactive screen control includes configuring an image-capturing module to capture a sequence of images of a gesture, configuring an analyzing module to determine whether the images captured by the image-capturing module match a predefined gesture corresponding to a function of an input device, and when it is determined that the images captured by the image-capturing module match the predefined gesture, configuring a processing module to perform an operation associated with the corresponding function of the input device and to control an interactive screen to show a result of the operation performed thereby.

Abstract: A system and method for data management is disclosed. The data management system comprises a database and a display interface. The database stores data and metadata, wherein the metadata corresponds to the data. The display interface comprises a graphical interface and a searching interface. The graphical interface is used to display the data. The searching interface is used to search the creation time, accessed time or the number of accesses of the data.

Abstract: An augmented reality system with mobile and interactive functions for multiple users includes two major portions: a computer system for handling augmented reality functions, and a user system for each user. The computer system for handling augmented reality functions has very powerful functionality for processing digital image data and transforming the digital image data into a three-dimensional virtual image for each user system. The user system mainly includes a Head-Mounted Display (HMD), a microphone and a PDA. A user can see the virtual image from the HMD and use the microphone or the PDA for communication with other users.
