Unlike most desktop computer and laptop, mobile interface are designed to facilitate user operating the information easily with various situations that is standing, walking, and moving. However, almost mobile devices such like cell phones have a small key pad and small display because those devices should keep compact and light weight for bringing and pocketing. Therefore, they impose a lot of burdens to users in terms of watching a small display and typing with a small keyboard. Such devices do not focus to provide implicit and awareness information. In this paper, we describe features of body worn projector, which has capability for projecting information to user’s peripheral vision, and body worn camera, which has capability for recognizing user’s posture and estimating user’s behavior, is suitable interface for providing awareness, implicit, and even explicit information. Finally, we propose two mobile interfaces which are “Palm top display for glance information” and “Floor projection from Lumbar mounted projector”.
