I conducted the user testing without giving them any prior notice and only reading from the interface, and they had some questions like when the game ends? So I added more text after that to make things more clear for the users. Other than that, once they got the hang of it, they were able to play the game easily and they figured out everything on how it works and how to stop. From the third iteration onwards, they become a master and play even better than I do(at least most of them). One area that could be improved is the addition of a text on the prototype saying Hover here or Put your hand here since they didn’t know where the sensor was in the beginning. That part of explaining where to hover the hand was the issue, which I will address by adding text on the prototype as mentioned.
