DESCRIPTION
Synchronized online gymnastics could provide new possibilities for enhancing the physical and social well-being of people with restricted mobility. We propose a prototype platform for this – Online-Gym – which allows users to interact using a Microsoft Kinect and participate in on-line gymnastics sessions. In this paper we present the Online-Gym concept and a first iteration on the platform architecture that allows interaction in virtual worlds with movement captured by a Kinect device. The exploratory work done so far makes evidence that this approach opens significant opportunities and these scenarios may be further developed, enhanced and enriched.

Interactive technologies and physical activity
• Videogames: high potential to promote physical exercise
• Exergames: provide to the user the development of sensory and motor skills
• “playing exergames could become one of the most popular, engaging, and health-promoting homework assignments of the twenty-first century”- Staiano and Calvert (2011)
Interactive technologies and physical activity
• Many elderly refuse to participating in regular training sessions outside their homes
• Exergames can help motivate elderly to exercise more
• 3D platforms: multi-user, collaborative, shared virtual environments, the “being there” presence
Motion Capture Devices

The Online-Gym project
• Online-Gym is an exploratory project prototyping an online 3D platform based on virtual worlds that allows users to interact with the system through the use of a motion capture device such as Microsoft Kinect

Conclusions• The Online-Gym project has a lot of potential for users who
are isolated, dispersed geographically or with reduced mobility.
• We should be careful particularly in the synchronization of the movements and their impact on the network for other users.
• The integration between virtual 3D platforms and motion capture devices have a huge margin for improvement and there is potential for development and deployment of such services.
Future work
• Need to further study the solutions for remote transmission of gestures made in front of the Kinect.
• How can we synchronize the movements made by each user physically distant.
• The issue of the platform independence
