GRID-PATTERN INDICATING INTERFACE FOR AMBIENT ASSISTED LIVING

This chapter proposes a grid-pattern indicating interface to provide instructions remotely for supporting the daily activities of elderly people living in their homes independently. Our aim is to realize smooth and easy telecommunication between supported senior citizens at their local site and supporting caregivers who are at a remote site. Although we have used a monitoring method with video streaming where the remote caregivers indicate work steps in a conventional way, occlusion and depth perception problems were occurring. Our proposed method can provide a grid-pattern interface to remote caregivers, which could be a solution for the occlusion and depth perception problems by indicating the spatial instruction easily on a 2D input interface. In this study, a prototype has been implemented with a colour camera, a range image sensor, and projector. It also demonstrated that the proposed grid-pattern indicating interface can help caregivers show an instruction easily and intuitively.
