Abstract
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.

A stabilization method of projected images for wearable projector applications
UbiComp '11: Proceedings of the 13th international conference on Ubiquitous computingStudies on supporting user task with a wearable projector are attracting attention in recent years. However, previous work did not consider the utilization in moving state because an image swing is caused by a body sway. Such instability of projected ...
Stabilization of Projected Image for Wearable Walking Support System Using Pico-projector
RTCSA '11: Proceedings of the 2011 IEEE 17th International Conference on Embedded and Real-Time Computing Systems and Applications - Volume 02In this paper, we propose a concept of real-time walking support system for the elderly who need preventive care. The system presents visual information on the floor by a wearable projector. Moreover, we describe a method to reduce swing of projected ...
Touch projector: mobile interaction through video
CHI '10: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsIn 1992, Tani et al. proposed remotely operating machines in a factory by manipulating a live video image on a computer screen. In this paper we revisit this metaphor and investigate its suitability for mobile use. We present Touch Projector, a system ...
