Eighteen participants played the same game in the three platforms. Results show that users generally did not like the setup using a screen and the best performances were obtained with the desktop configuration. This result could be due to the fact that most users were gamers used to the interaction through keyboard/mouse. Still, we noticed that user performance in the HMD setup was not dramatically worse and that users do not collide as often with walls.Categories and Subject Descriptors (according to ACM CCS): H.5.2 [Information Interfaces and Presentation]: User Interfaces: Input Devices and Strategies
