Cloud computing is becoming an increasingly viable source of low cost computing power for developers and users in diverse areas. Services from the creation of presentations, spreadsheets and text processing, to picture and video editing, and more recently high performance scientific computing are some examples of systems currently available in the cloud.(More)
Mobile phone games are usually design to be able to play using the traditional number pads of the handsets. This is stressfully difficult for the user interaction and consequently for the game design. Because of that, one of the most desired features of a mobile games is the usage of few buttons as possible. Nowadays, with the evolution of the mobile(More)
The automatic detection and tracking of human body parts in color images is highly sensitive to appearance features such as illumination, skin color and clothes. As a result, the use of depth images has been shown to be an attractive alternative over color images due to its invariance to lighting conditions. However, body part detection and tracking is(More)
Background subtraction is an important preprocessing step in many modern Computer Vision systems. Much work has been done especially in the field of color image based foreground segmentation. But the task is not an easy one so, state of the art background subtraction algorithms are complex both in programming logic and in run time. Depth cameras might offer(More)
This article presents a new architecture to implement all game loop models for games and real-time applications that use the GPU as a mathematics and physics coprocessor, working in parallel processing mode with the CPU. The presented model applies automatic task distribution concepts. The architecture can apply a set of heuristics defined in Lua scripts in(More)
Digital games are usually developed to provide fun for people of all ages. Although games have been mostly used for entertainment purposes, they have great potential as an intervention tool in health care. Digital games can be applied in health care helping users to learn or to experience something in a fun way. However, there are important issues to be(More)
Most game engines are based on inheritance of game objects and/or componentization of behaviors. While this approach enables clear visualization of the system architecture, good code reuse, and fast prototyping, it brings some issues, mostly related to the high dependency between game objects/components instances. This dependency often leads to static casts(More)
