Smartphone-based computer vision travelling aids for blind and visually impaired individuals: A systematic review

Abstract

This survey/interview is a part of a research project titled "Complex research of augmented reality for the blind and weak-sighted people" (project No. 01.2.2-LMT-K-718-01-0060) funded by European Regional Development. The overall goal of the project is development of a functional computer vision-based travelling aid for the blind and weak-sighted people. This survey aims to identify and describe requirements and expectations visually impaired users have for such technological solutions. The survey is strictly anonymous. The project team is grateful for your time and effort dedicated for filling in this questionnaire/participating in this interview.

Recent trends in computer vision-driven scene understanding for VI/blind users: a systematic mapping

“…Each of these methods have their drawbacks. According to [87] representative surveys cost money and time, the thinkaloud protocol is not accurate because the environment is not natural to the user and the tasks are usually performed in a controlled environment; field experiments may not represent the correct population; remote testing needs additional tools for collecting data; and interviews do not sufficiently cover usability issues. Additionally, controlled environment testing might not consider some factors that exist in the real environment which may affect the user's experience.…”

A Systematic Review of Urban Navigation Systems for Visually Impaired People

“…However, they did not discuss the future work of ETAs or compare between available systems. Budrionis et al [ 18 ] compared 15 mobile navigation applications that use computer vision. A comparison was done from distinct perspectives (objectives/functions, input/output, data processing, algorithms, and evaluation of the solution).…”

“…They identified the advantages and limitations of six smartphone applications [ 19 ]. Budrionis et al [ 18 ] and Kuriakose et al [ 19 ] included a limited number of navigation systems. This lack of included articles eliminates use of these surveys as a complete overview of the area.…”

Low Vision With A Squint

“…() 5 review smartphone based assistive technology, on a range of @edge algorithms, asymptotically approximating the ideal object mirror in external navigation and several tests including OCR use cases, the review indicates the success of both SLAM and DNN algorithms compared to older algorithms like SIFT, with no commercial systems like Google Lookout evaluated.…”
