The video here shows an interesting interaction with an AR application in a mobile device. The user can interact with AR content by shaking and moving their cellphone, instead of touching any buttons on the screen. This kind of physical interaction seems more natural and smooth in the context of seeing additional content through small screens. When AR characters or models have reactions according to the movement of mobile devices, users will be able to get more immersive into the experience.
However, while physical interaction seems more nature, it takes longer to learn than traditional screen-based interactions. For instance, people are not sure which movement is connected to which commend, as well as the appropriate extent, angle or frequency that they should apply. In this case, if user scenario happens in a museum or an exhibition, most user will take it as an one-time experience, which means high learning cost might decrease their gratification and cause negative emotions.
