Abstract: Disclosed herein are a cloud service brokerage method and apparatus using a service image store. The cloud service brokerage apparatus includes a reception unit for receiving service requirements from each of users, a service image recommendation unit for recommending one or more candidate service images that satisfy the requirements among multiple service images stored in a service image store, a cloud server recommendation unit for recommending one or more candidate cloud servers that satisfy the requirements among multiple cloud servers, a registration unit for registering an optimal service image selected by the user from among the one or more candidate service images in an optimal cloud server selected by the user from among the one or more candidate cloud servers, and a transmission unit for transmitting results of a service implemented by executing the optimal service image on the optimal cloud server to the user.

Abstract: An apparatus and method of implementing haptic-based networked virtual environments supporting high-resolution tiled displays. A haptic rendering process of detecting collision between a user of a haptic-device over a virtual environment and each of at least one virtual object and providing a physical force corresponding to a detection result to the haptic-device is performed, and a graphic rendering process of converting each virtual object represented as 3-D data into an object stream represented as 2-D data such that each virtual object is displayed as a 2-D image, and assigning a priority and a frame rate to each converted object stream according to a preset assignment criterion is performed. A plurality of displays provide a display image, including object streams of the virtual objects and background pixels, so that a virtual environment allowing the user of the haptic-device to visually and tactilely immerse thereto is effectively realized by utilizing limited resources.
