Recently, there are many projects and practices, which a user wears a mobile projector that displays images on a floor and a wall to support his/her task. However, in this situation, projected images are unstable and it makes communication and task support difficult. The viewability of the projected image depends on several factors; the position of wearing projector, user context such as walking and standing, and the type of presenting contents. Therefore, we propose a method for selecting a projector from multiple wearing projectors considering these factors. We investigate the characteristics in the viewability by changing various parameters and the prototype system selects a suitable projector dynamically in response to current situation.
