Experimental Demonstration in Exhibition Spacewith a Navigation Robot for People with Visual Impairments

We describe a demonstration experiment conducted to examine the usage scenarios and evaluate the functionality of the autonomous mobile robot ``AI Suitcase,'' which supports the mobility of people with visual impairments in unfamiliar environment. 11 participants with visually impairements walked around the exhibition space together with the robot, which provided voice guidance at various points. We conducted interviews regarding their needs for the exhibition spaces (ex. art galleries and museums) and the operability of the robot, and identified both advantages and areas for improvement. Additionally, based on speed data during navigation and the participants' understanding of the exhibit content, we confirmed the high compatibility between the exhibition spaces and the navigation robot.
