“…Kaiser and Lawo [16] suggested an indoor and outdoor navigation system whose indoor navigation system is based on an integrated system of simultaneous localization and mapping (SLAM) approach which has been designed for mobile robots and an inertial measurement unit (IMU) which usually contains accelerometers, gyroscope and magnetometers. On the other hand, their outdoor system is based on a combination of GPS and Pedestrian Dead Reckoning (PDR).…”

Abstract-The aim of this paper is to describe a new Navigation technique to assist the blind and people with low vision to reach their destinations in an indoor environment. The proposed technique is based on our previous positioning technique using active Radio-frequency identification (RFID) technology. A Global Positioning System (GPS) does not work efficiently in indoor environments. This research produced a navigation service for sighted and blind people to assist them to reach their destination of interest via the shortest path. Tags were distributed at known locations and the mobile reader was carried by a user. The system role is to determine the shortest path to the destination which was indicated by a user. When the shortest path is calculated, the system indicates way points in the path which were represented by active tags in this scenario. Then the users are navigated to these points one by one via QR-Code till they reach their destinations. It was implemented in an indoor environment as a simulation system to navigate the user to particular offices with a successful shortest path identification rate and satisfactory navigation results were achieved.

Notably valuable efforts have focused on helping people with special needs. In this work, we build upon the experience from the BlindHelper smartphone outdoor pedestrian navigation app and present Blind MuseumTourer, a system for indoor interactive autonomous navigation for blind and visually impaired persons and groups (e.g., pupils), which has primarily addressed blind or visually impaired (BVI) accessibility and self-guided tours in museums. A pilot prototype has been developed and is currently under evaluation at the Tactual Museum with the collaboration of the Lighthouse for the Blind of Greece. This paper describes the functionality of the application and evaluates candidate indoor location determination technologies, such as wireless local area network (WLAN) and surface-mounted assistive tactile route indications combined with Bluetooth low energy (BLE) beacons and inertial dead-reckoning functionality, to come up with a reliable and highly accurate indoor positioning system adopting the latter solution. The developed concepts, including map matching, a key concept for indoor navigation, apply in a similar way to other indoor guidance use cases involving complex indoor places, such as in hospitals, shopping malls, airports, train stations, public and municipality buildings, office buildings, university buildings, hotel resorts, passenger ships, etc. The presented Android application is effectively a Blind IndoorGuide system for accurate and reliable blind indoor navigation.

To achieve safe and independent mobility, people usually depend on published information, prior experience, the knowledge of others, and/or technology to navigate unfamiliar outdoor and indoor environments. Today, due to advances in various technologies, wayfinding and navigation systems and services are commonplace and are accessible on desktop, laptop, and mobile devices. However, despite their popularity and widespread use, current wayfinding and navigation solutions often fail to address the needs of people with disabilities (PWDs). We argue that these shortcomings are primarily due to the ubiquity of the compute-centric approach adopted in these systems and services, where they do not benefit from the experience-centric approach. We propose that following a hybrid approach of combining experiencecentric and compute-centric methods will overcome the shortcomings of current wayfinding and navigation solutions for PWDs.
