This paper describes a novel remote assistance system developed by my research group as one of the contributions of my research activity in Strategic Young Research Overseas Visits Program for Accelerating Brain Circulation. In this system, an instructor being in a remote site provide instructions with voice and visual markers to an operator on procedures. The instructor can observe the workspace through camera images and show object positions to the operator with a projector marker. In contrast to the traditional studies treating with simplified transparent and reflective objects. The system measures surface shapes and reflection properties by using the camera and projector in advance, then utilizes the extracted projectable regions for efficient instruction with marker. The experiments demonstrate that the efficiency of perception of markers can increase by projecting them only on the projectable areas in an environment where are reflective and transparent objects.

This report outlines results during a visit to University of Oulu, Finland, funded by Japan Society for the Promotion of Science (JSPS). I have proposed two methods for an interaction with senior citizens and supporting systems: One is Re-PITASu (Rangeimage-Projector Interaction Tool for Arbitrary Surfaces) and the other is grid-based work indication for senior citizens. I have proposed a calibration method between a camera, a range image sensor and a projector to implement the systems. Two papers about Re-PITASu have been published in international conferences. Furthermore, I am planning to publish these final results in a journal.

This paper presents a tele-guidance system for elderly people so that they can walk outdoors without an escort and their caregivers can monitor them or guide them from remote site when they are in a need of help. The feature point of the proposed system is to adopt laser projection with consideration for use outdoor. Because the laser projection shows the arrow, which indicates a direction, all a user needs to do is to follow it intuitively. The goal of this study is to realise a tele-guidance system, which provides easy understanding for elderly users with mild dementia, with laser projection. The whole system including this proposed system aims to make preparations for a super-graying society by connecting elderly people and caregivers effectively via ubiquitous network. As a first step, a prototype system was developed and a user test was conducted with elderly participants. In the result, some technical problems and visibility problems on the projected arrow were found.
