This research investigates if there is potential for opening up new experiences in games using stereoscopic 3D. For games to work in S-3D they need be designed from the start to make best use of the technology. The research approach adopted was a practical investigation using volunteers to play 2D and S-3D games before answering a questionnaire on the effects of stereoscopic 3D in gameplay. The findings show that games that were designed to work in 2D that were subsequently converted to S-3D do not transfer very well. Overall the study found that games targeted to stereoscopic 3D audiences and devices must be designed from the start with stereoscopic 3D in mind. To ensure S-3D can increase immersion, designers must focus on building in the key elements of immersion that can only be achieved in S-3D.
