BACKGROUND Many weight-loss programs in children are performed without specific foci on training both physical fitness and motor skills. The aim of this study was to describe the effect of a one-year weight-loss program on children's motor skills and physical fitness. METHODS Participants included 115 overweight fifth-grade children (12.0 years) randomized into either a Day-Camp Intervention ...

Virtual reality (VR) has the potential to substantially alter the manner in which products of the future are engineered. Currently there are many applications of VR during the product engineering process from design and analysis through to process planning, assembly, machining and shop floor layout. VR takes a multitude of forms, including immersive, desktop, augmented, and is rapidly developin...

Virtual reality systems provide realistic look and feel by seamlessly integrating three-dimensional input and output devices. One software architecture approach to constructing such systems is to distribute the application between a computation-intensive simulator back-end and a graphics-intensive viewer frontend which implements user interaction. In this paper we discuss Metis, a toolkit we ha...

We designed an interactive 3D user interface system to perform object modeling in virtual environments. Expanding on existing 3D user interface techniques, we integrate low-cost human gesture recognition that endows the user with powerful abilities to perform complex virtual object modeling tasks in an immersive game setting. Much research has been done to explore the possibilities of developin...

Over the past fifty years, artists have explored the computer’s potential to create both virtual and physical art forms that embrace the concept of space. Through the use of immersion, interaction, and manipulation of both virtual and physical space, computer artists have created powerful aesthetic environments that enable audiences to experience alternative realities. Immersive installations t...

In this paper, we present a new application framework aimed to support distributed synchronous collaboration using multi-touch interaction. The framework supports 2D and 3D virtual workspaces that enable two or more users to collaboratively or cooperatively manipulate shared objects with multi-touch interfaces. We present two applications developed with the aim to explore 2d/3d immersive collab...

the last few years immersive virtual environment technology has matured to the point where industry researchers have begun using it for the design and evaluation of new systems. Immersive virtual environments have already been applied to a wide variety of domains , including automobile design, flight simulation, emergency rescue, and remote surgical training. As VEs move from research laborator...

Developing, testing and operating complex machinery and repairing it under time pressure if it breaks down are some of the new skills professionals in many occupations have to learn as quickly as possible. Actions on machinery and plants are trained in individual lessons on an immersive virtual model. Lessons can be repeated as often as desired and independent of the real machinery’s temporal a...

Immersive learning conceptualizes education as a set of active phenomenological experiences that are based on presence. can be implemented using both physical and digital means, such virtual reality augmented reality.
