A Robotic Wayfinding System for the Visually Impaired

چکیده
We present an emerging indoor assisted navigation system for the visually impaired. The core of the system is a mobile robotic base with a sensor suite mounted on it. The sensor suite consists of an RFID reader and a laser range finder. Small passive RFID sensors are manually inserted in the environment. We describe how the system was deployed in two indoor environments and evaluated by visually impaired participants in a series of pilot experiments.

A Vision-Based Wayfinding System for Visually Impaired People Using Situation Awareness and Activity-Based Instructions
A significant challenge faced by visually impaired people is 'wayfinding', which is the ability to find one's way to a destination in an unfamiliar environment. This study develops a novel wayfinding system for smartphones that can automatically recognize the situation and scene objects in real time. Through analyzing streaming images, the proposed system first classifies the current situation ...
متن کاملFunctional Assessment of a Camera Phone-Based Wayfinding System Operated by Blind and Visually Impaired Users
We describe a wayfinding system for blind and visually impaired persons that uses a camera phone to determine the user's location with respect to color markers, posted at locations of interest (such as offices), which are automatically detected by the phone. The color marker signs are specially designed to be detected in real time in cluttered environments using computer vision software running...
متن کاملCell Phone-based Wayfinding for the Visually Impaired
A major challenge faced by the blind and visually impaired population is that of wayfinding – the ability of a person to find his or her way to a given destination. We propose a new wayfinding aid based on a camera cell phone, which is held by the user to find and read aloud specially designed machine-readable signs in the environment (labeling locations such as offices and restrooms). Our main...
متن کاملA Mobile Phone Wayfinding System for Visually Impaired Users.
In past work [1] we described a novel system for aiding blind and visually impaired persons in wayfinding – the process of finding one’s way to a destination. This system consists of a mobile phone held by the user that detects and reads specially designed printed signs (Fig. 1) using its built-in camera. Experiments have demonstrated the ability of blind and visually impaired persons using the...
متن کاملSearch Strategies of Visually Impaired Persons Using a Camera Phone Wayfinding System
We report new experiments conducted using a camera phone wayfinding system, which is designed to guide a visually impaired user to machine-readable signs (such as barcodes) labeled with special color markers. These experiments specifically investigate search strategies of such users detecting, localizing and touching color markers that have been mounted in various ways in different environments...
