Enabling building service robots to guide blind people a participatory design approach

Abstract

Building service robots - robots that perform various services in buildings - are becoming more common in large buildings such as hotels and stores. We aim to leverage such robots to serve as guides for blind people. In this paper, we sought to design specifications that detail how a building service robot could interact with and guide a blind person through a building in an effective and socially acceptable way. We conducted participatory design sessions with three designers and five non-designers. Two of the designers and all of the non-designers had a vision disability. Primary features of the design include allowing the user to (1) summon the robot after entering the building, (2) choose from three modes of assistance (Sighted Guide, Escort, and Information Kiosk), and (3) receive information about the building's layout from the robot. We conclude with a discussion of themes and a reflection about our design process that can benefit robot design for blind people in general.
