Study
Of course, the benefits of Sports over a Distance needed to be evalued scientifically. Therefore, 56 volunteers were recruited through flyers and email postings at local universities, sports clubs and youth hostels to participate in an experiment. None of them knew about the study beforehand nor had they any prior experience with the system. The volunteers were matched up randomly in teams of two and no pair of participants knew each other prior to the experiment.
Experimental Design
The experiment had two conditions: exertion and non-exertion. The participants played either Breakout for Two, or a non-exertion analogous version of the game using a traditional keyboard interface.
