“…This system offered only one-way communication. Bischof et al developed a wireless local area network (WLAN) communication system named NAVCOM [ 24 ]. The authors proposed that blind people need a feedback to acknowledge whether the bus drivers get the original message.…”

Visually impaired people have difficulty accessing information about public transportation systems. Several systems have been developed for assisting visually impaired and blind people to use the city bus. Most systems provide only one-way communication and require high-cost and complex equipment. The purpose of this study is to reduce the difficulties faced by visually impaired people when taking city buses, using an interactive wireless communication system. The system comprised a user module and a bus module to establish a direct one-to-one connection. When the user inputs 4-digit numbers, the user module immediately sends out the information. If the bus module receives the matched bus number, it buzzes and the warning LED flashes to notify the bus driver that someone is waiting to board on the bus. User tests were conducted by two visually impaired people in a simulated vehicle and a city bus. The success rate of interactive wireless communication, recognizing the arrival of the bus and boarding the correct bus reached 100% in all of the tests. The interactive wireless communication aid system is a valid and low-cost device for assisting visually impaired people to use city buses.

Visually impaired and blind people (VIBP) face great difficulty finding public transport and bus stops due to their visual impairments. Over the past decade, several support systems have been prototyped and developed to address this problem. However, most of these are wearable prototypes that turn out to be grueling for them. In this project, we propose an AI-powered real-time bus navigation system that provides information about buses arriving at bus stops. The buses will be tracked using the GPS of the mobile phone installed with the driver-side application. The application will take audio input for the source and destination for the journey and provide the available buses from the nearest location of the user on that route as audio output. It will provide the ETA and location of the target bus. This app will coordinate with the driver’s app and live notifications will be given to the driver for any visually impaired passenger.

“…The GuideCane is of particular interest because it integrates two functions: obstacle detection and navigation assistance. Second, there are systems that contextually interact with the environment, like those that are able to give information about transportation [16]. This is the case of remote-controlled auditory signals, such as those used in traffic signals.…”

Perception Assistance for the Visually Impaired Through Smart Objects: Concept, Implementation, and Experiment Scenario

et al. 2020

The last few years have seen substantial progress in the field of smart objects (SOs): their number, diversity, performance and pervasiveness have all been quickly increasing and this evolution is expected to continue. To the best of our knowledge, little work has been made to leverage this abundance of resources to develop assistive devices for Visually Impaired People (VIP). However, we believe that SOs can both enhance traditional assistive functions (i.e. obstacle detection, navigation) and offer new ways of interacting with the environment. After describing spatial and non-spatial perceptive functions enabled by SOs, this article presents the SO2SEES, a system designed to be an interface between its user and neighboring SOs. The SO2SEES allows VIP to query surrounding SOs in an intuitive manner, relying on knowledge bases distributed on Internet of Things (IoT) cloud platforms and the SO2SEES's own back-end. To evaluate and validate the exposed concepts, we have developed a simple working implementation of the SO2SEES system using semantic web standards. A controlled-environment test scenario has been built around this early SO2SEES system to demonstrate its feasibility. As future works, we plan to conduct field experiments of this first prototype with VIP end users.
