Screen-less devices allow for the smallest form factor and thus the maximum mobility. However, current screen-less devices do not support spatial interaction (such as pointing) because, seemingly, there is nothing to point at. We challenge that notion and with a series of experiments investigate the question: to what extent can users interact spatially with a user interface that exists only in their imagination? To test this question we developed a gesture sensing device that determined the position of both hands in front of the user. Users define the origin of an imaginary interaction plane with an L-shaped posture of their non-dominant hand and interact in the resulting space with their other. We found that users can exploit their visual short-term memory to, at least in part, replace the feedback conventionally displayed on a screen. In this talk I will present the details of this research and our vision of Imaginary Interfaces, a new style of mobile interaction where all visual “feedback” takes place in the user’s imagination.
