Multi wall stereo projection (MWSP) systems are an emerging display paradigm, promising a new quality in 3d-real-time interactions. Not much is known about the ergonomics of these systems. This paper describes two experiments of user perception and interaction to obtain a better understanding of user interactions with existing projection technology. The first task is the estimation of absolute geometrical dimensions of simple objects. The second task is grabbing simple objects of different sizes. For both experiments quantitative data was collected as a measure of interaction quality. In order to classify MWSPs, these tasks were compared to other display devices and compared to physical reality. Due to the limited number of participants these experiments are considered as case-studies only.
