Digital tabletops present numerous benefits in face-to-face collaboration environments. However, their integration in real settings is complicated by cost and fixed location. In this respect, building table-like environments using several handheld devices such as tablets or smartphones provides a promising alternative but is limited to touch interaction only. We propose instead another kind of "around-device" interaction (ADI) technique using the built-in front camera of these devices and fiducial frame markers, which presents advantages including better awareness and less interference. This paper contributes a first step in exploring the potential of this interaction technique by conducting a usability test comparing several ergonomic factors that may have an effect on the very first operation of the interaction: the acquisition of the marker.
