MHP Oriented Interactive Augmented Reality System for Sports Broadcasting Environments

Television and movie images have been altered ever since it was technically possible. Nowadays embedding advertisements, or incorporating text and graphics in TV scenes, are common practice, but they can not be considered as integrated part of the scene. The introduction of new services for interactive augmented television is discussed in this paper. We analyse the main aspects related with the whole chain of augmented reality production. Interactivity is one of the most important added values of the digital television: This paper aims to break the model where all TV viewers receive the same final image. Thus, we introduce and discuss the new concept of interactive augmented television, i. e. real time composition of video and computer graphics - e.g. a real scene and freely selectable images or spatial rendered objects - edited and customized by the end user within the context of the user's set top box and TV receiver.

‘Continue or terminate?’ Determinants of long-term volunteering in sports clubs

This study analyzed the determinants underlying sports club volunteers' tendencies to continue or terminate their long-term commitment to volunteering in order to help sports clubs improve their volunteer management. Their risk of terminating was viewed in terms of subjective expectations and evaluations (satisfaction) regarding club-related working conditions and normative commitments (solidarity) to the sports club. These relationships were tested empirically with an online questionnaire of 441 sports club volunteers in a selection of 45 Swiss sports clubs. Results showed that the constructs orientation toward collective solidarity and volunteer job satisfaction correlated positively with long-term volunteering commitment. The effect of the former was stronger than that of the latter. Volunteers with a higher orientation toward collective solidarity were unlikely to terminate their voluntary engagement in their club. The discussion presents recommendations to help clubs retain volunteers.
