“…The TARSIUS system [83] aimed at enhancing the capability of users in the visual scene understanding of the outdoor environments. The system components include the TARSIUS app for mobile devices, a web server, a remote assistance centre, and also the Bluetooth LE/iBeacon tags placed along the streets at points of interest.…”

The development of navigation tools for people who are visually impaired had become an important concern in the research area of assistive technologies. This paper gives a comprehensive review of different articles published in the area of navigation solutions for people who are visually impaired. Unlike other review papers, this review considers major solutions that work in both the indoor or/and outdoor environments which are based on different technology. From the review, it became clear that the navigation systems proposed for the target users lack some core features that are quite important for independent navigation. Also, there can be instances in which humanitarian conditions also have to be considered in the navigation system design. Based on these findings, a set of recommendations are also given which can be considered in the future design of navigation systems for blind and visually impaired people.

“…Within the games, she could see the sharp contrasts but could not see any of the details that were camouflaged or too close in color to other aspects within the game. She compared the game experience to other experiences and technologies, such as mobile warning devices (Mataro et al, 2017) and VR devices that calibrate to vision impairment and help to see details that cannot be seen with only corrective lenses in glasses (See online advertisements for Jordy devices). Her experiences with physical O&M training over the years were insightful to assess the aspects of the gaming environments for possible implementation using educational technology for O&M training and practice; something that is being driven by economic factors.…”

This action research study examined the design elements of three VR games that used an HTC VIVE VR helmet, two HTC game controllers, and a VR horse simulator for functionality and transferability to orientation and mobility (O&M) education for visually impaired individuals. The functionality of the VR games was tested with a visually-impaired individual based upon five characteristics that are important to O&M education: perimeter scanning then grid scanning, hearing, touch, smell, and perceptions of body positions. The horse simulator has potential benefits for proprioception and kinesthesia development. The inconsistent haptic feedback requires redesign consideration for inclusion within VR games and systems for O&M education of visually impaired individuals.

“…The foremost reason behind the visual loss or impairment is mainly glaucoma (2%), unoperated cataract (33%) and uncorrected refractive errors: astigmatism or hyperopia, myopia (43%). Overall, 80% of the all the visual impairments can be prevented or cured [2]. WHO also reported that people with sensory disabilities affect 5.3% of the world population and 9.3% of the world population for audition and vision impairments respectively [3].…”

The loss of vision restrained the visually impaired people from performing their daily task. This issue has impeded their free-movement and turned them into dependent a person. People in this sector did not face technologies revamping their situations. With the advent of computer vision, artificial intelligence, the situation improved to a great extent. The propounded design is an implementation of a wearable device which is capable of performing a lot of features. It is employed to provide visual instinct by recognizing objects, identifying the face of choices. The device runs a pre-trained model to classify common objects from household items to automobiles items. Optical character recognition and Google translate were executed to read any text from image and convert speech of the user to text respectively. Besides, the user can search for an interesting topic by the command in the form of speech. Additionally, ultrasonic sensors were kept fixed at three positions to sense the obstacle during navigation. The display attached help in communication with deaf person and GPS and GSM module aid in tracing the user. All these features run by voice commands which are passed through the microphone of any earphone. The visual input is received through the camera and the computation task is processed in the raspberry pi board. However, the device seemed to be effective during the test and validation.
