How Does Delegation in Social Interaction Evolve Over Time? Navigation with a Robot for Blind People

Autonomy and independent navigation are vital to daily life but remain challenging for individuals with blindness. Robotic systems can enhance mobility and confidence by providing intelligent navigation assistance. However, fully autonomous systems may reduce users’ sense of control, even when they wish to remain acti…

Eyes on the Finger: Investigating a Ring-Shaped Camera for Seamless Accessible Tactile Exploration

Tactile exploration is essential for blind and low vision (BLV) individuals to understand objects and spaces. Yet little is known about how camera-based devices can support hand-centric exploration: tactilely examining exhibits while inquiring about and processing information. We investigate a finger-worn ring camera…

Robot-Assisted Group Tours for Blind People

Group interactions are essential to social functioning, yet effective engagement relies on the ability to recognize and interpret visual cues, making such engagement a significant challenge for blind people. In this paper, we investigate how a mobile robot can support group interactions for blind people. We used the s…

Beyond Omakase: Designing Shared Control for Navigation Robots with Blind People

Autonomous navigation robots can increase the independence of blind people but often limit user control—following what is called in Japanese an "omakase" approach where decisions are left to the robot. This research investigates ways to enhance user control in social robot navigation, based on two studies conducted wi…

WanderGuide: Indoor Map-less Robotic Guide for Exploration by Blind People

Blind people have limited opportunities to explore an environment based on their interests. While existing navigation systems could provide them with surrounding information while navigating, they have limited scalability as they require preparing prebuilt maps. Thus, to develop a map-less robot that assists blind peo…

Snap&Nav: Smartphone-based Indoor Navigation System For Blind People via Floor Map Analysis and Intersection Detection

We present Snap&Nav, a navigation system for blind people in unfamiliar buildings, without prebuilt digital maps. Instead, the system utilizes the floor map as its primary information source for route guidance. The system requires a sighted assistant to capture an image of the floor map, which is analyzed to create a…

ChitChatGuide: Conversational Interaction Using Large Language Models for Assisting People with Visual Impairments to Explore a Shopping Mall

To enable people with visual impairments (PVI) to explore shopping malls, it is important to provide information for selecting destinations and obtaining information based on the individual's interests. We achieved this through conversational interaction by integrating a large language model (LLM) with a navigation sy…

Enhancing Blind Visitor's Autonomy in a Science Museum Using an Autonomous Navigation Robot

Enabling blind visitors to explore museum floors while feeling the facility's atmosphere and increasing their autonomy and enjoyment are imperative for giving them a high-quality museum experience. We designed a science museum exploration system for blind visitors using an autonomous navigation robot. Blind users can…

PathFinder: Designing a Map-less Navigation System for Blind People in Unfamiliar Buildings

Indoor navigation systems with prebuilt maps have shown great potential in navigating blind people even in unfamiliar buildings. However, blind people cannot always benefit from them in every building, as prebuilt maps are expensive to build. This paper explores a map-less navigation system for blind people to reach d…

LineChaser: A Smartphone-Based Navigation System for Blind People to Stand in Line

Standing in line is one of the most common social behaviors in public spaces but can be challenging for blind people. We propose an assistive system named LineChaser, which navigates a blind user to the end of a line and continuously reports the distance and direction to the last person in the line so that they can be…
