Project title : An indoor navigation for visually impaired people utilizing Ultra Wide Band Technology
Autonomous navigation is a crucial component for visually impaired people. Outdoors, positioning based on ubiquitous signals is feasible; however, for indoors, no universal positioning solution does exist. Due to the remarkably broad bandwidth, ultra-wideband (UWB) signs offer a proper multipath resolution and allow positioning with sub-meter (10 centimeter) accuracy. Also, because of the implementation of screen-reader software into mobile devices, visually impaired people start using smartphones. While creating a navigation system for the blind, this project focuses on adding sensors such as IMU, in wearable form, for increasing the accuracy of UWB modules. Finally, e-sense technology, implemented in earables, provides haptic feedback in guiding the visually impaired.
- Provide a voice command system to help blind people navigate in indoor locations
- Implementation of an Ultra-wideband (UWB) real time localization system
- Calculation of shortest path from user’s location to destination
- Android app with speech recognition and text to speech synthesis
- Usage of bluetooth beacons to improve upon accuracy of the system
- Integration of the three subsystems via communication protocols
- Minuet: Multimodal Interaction with an Internet of Things
- Pozyx: Localization via UWB
- Indoor Positioning for Visually Impaired People Based on Smartphones
- Analysis of a UWB Indoor Positioning System Based on Received Signal Strength
- Methodology:
- The indoor localization section: We will be building on an existing work mentioned in the related works section (item #1) to improve the 3d mapping of current UWB modules for indoor localization.
- App development section: An Android app would be used to interface between the mapping system and the user.
- MQTT Communication Protocol: For receiving sensors data and setting up a CGI server for the purpose of the project.
- Riyya : Android application development
- Amir : UWB system setup, overall system integration
- Julian : Server setup, support on Android app development
