Challenges in designing navigation system for visual impaired people in AV?5 answersDesigning navigation systems for visually impaired people in autonomous vehicles (AV) presents several challenges. One of the main challenges is to develop effective tools that can assist visually impaired individuals in navigating complex real-life environments. These tools can include software and hardware-oriented solutions based on technologies such as computer vision, SLAM algorithms, and embedded systems. Another challenge is to ensure the safety and comfort of visually impaired users by detecting and displaying obstacles, potholes, and road signs. Additionally, the system should provide guided instructions and user-friendly interfaces to help visually impaired individuals select and navigate appropriate routes. Overcoming these challenges requires a combination of machine learning, smart canes, wearable smart glasses, and voice assistance to provide effective navigation support for visually impaired individuals in AV.
Is there a survey for technologies used to assist visually impaired individuals?5 answersSeveral surveys and literature reviews have been conducted on technologies used to assist visually impaired individuals. Bamdad et al. conducted an anonymous survey to understand the experience and needs of visually impaired and blind (VIB) people regarding digital assistive technologies for navigation. Yadav et al. highlighted the need for and importance of introducing assistive devices to visually impaired individuals and creating awareness among caregivers and eye care professionals. Another study proposed a device using sensors and voice commands to assist the blind in measuring distances.

What are the challenges and limitations of existing wayfinding and navigation assistance for blind and visually impaired people?5 answersExisting wayfinding and navigation assistance for blind and visually impaired people face several challenges and limitations. These include the need for devices to recognize a wide range of targets, but the text reading aloud module cannot read all of them. Many existing navigation alternatives are either too heavy or too expensive for universal use. Additionally, while most devices focus on detecting obstacles, visually impaired individuals require assistance with tasks such as knowing their exact position and staying informed along a route. Furthermore, the mobility of visually impaired people involves more than just obstacle detection, requiring information on object location and content to aid navigation in unfamiliar environments. Lastly, there is a need for standalone and customizable solutions that can process the surroundings of visually impaired individuals and provide information about nearby places.
What are existing approaches to assisting navigation and wayfinding among people who are blind or visually impaired?5 answersExisting approaches to assisting navigation and wayfinding among people who are blind or visually impaired include the development of assistive devices and systems. These devices and systems utilize technologies such as AI, sensor technology, ultrasonic sensors, and object detection algorithms to provide real-time feedback and audio cues to the user about their environment. Some approaches focus on indoor navigation and obstacle detection, using ontology-based algorithms to predict trajectories and alert users to the presence of obstacles. Other approaches involve the use of IoT technology, such as smart shoes and smart glasses, which incorporate sensors and micro-controllers to detect obstacles and provide alerts to the user. These approaches aim to improve the independence, safety, and overall quality of life for visually impaired individuals by enhancing their ability to navigate and interact with their surroundings.
Does visually impaired use mobile phone?2 answersVisually impaired individuals use mobile phones, particularly smartphones and tablets, as a means of communication, information sharing, and accessing various functionalities. These devices have built-in accessibility features that cater to the needs of visually impaired users. Mainstream devices are frequently used by visually impaired adults in place of or in combination with traditional assistive aids for specific tasks such as object identification, navigation, requesting sighted help, listening to audiobooks, reading eBooks, and optical character recognition. However, touchscreen mobile phones can be inaccessible for visually impaired users due to the absence of physical keys and insufficient accessibility features. Various accessibility applications and techniques, such as speech to text converters, text to speech converters, image recognition, and Braille script, have been developed to address this issue. Although basic access is available, there are still many accessibility issues that need to be addressed to ensure full inclusion for visually impaired individuals.
