Many projects and practices can now support user tasks by presenting images on the floor or wall using a mobile projector. However, unstable images make communication and task support difficult. The viewability of a projected image depends on several factors; the position of the wearable projector, user contexts such as whether he/she is walking or standing, and the type of presentation content. We describe a method for selecting a projector from multiple wearable projectors, wherein the method considers these factors. We investigated the characteristics of viewability by changing various factors in various contexts and with different content. We also investigated the appropriate position for a wearable mobile projector in various situations and with different content in subjective evaluations. The results indicated that our system dynamically changes the characteristics of a projector for presenting content. We implemented a prototype system that selects the appropriate projector dynamically in response to the situation.
