“…Kostyra and co-workers found that sensory attributes are important for PVI when they select different products that have the same appearance. They performed a questionnaire, and the results showed that using mobile devices can make PVI feel independent during the shopping process, which is important to them [11].…”

“…Earlier studies [8,11,48] assume that shopping list preparation is a useful activity, as most PVI prefer to follow a predetermined list. It is necessary to help PVI prepare shopping lists and store them in a database.…”

“…It is also difficult for them to get detailed information about products, such as production and expiration date. Additionally, PVI always need help from others, as most shops are not well prepared to help them [11]. As a result, researchers have developed multiple solutions to help PVI navigate and identify products.…”

“…For example, PVI have difficulties in reading product labels during shopping; they thus miss important information about the content of their food and sometimes make bad choices. During shopping, PVI also face navigation troubles, which encourage them to consume takeout [10,11]. Another problem is how to walk in an environment with many barriers such as walking in unknown places or crossing a street [12,13].…”

People with visual impairment face various difficulties in their daily activities in comparison to people without visual impairment. Much research has been done to find smart solutions using mobile devices to help people with visual impairment perform tasks like shopping. One of the most challenging tasks for researchers is to create a solution that offers a good quality of life for people with visual impairment. It is also essential to develop solutions that encourage people with visual impairment to participate in social life. This study provides an overview of the various technologies that have been developed in recent years to assist people with visual impairment in shopping tasks. It gives an introduction to the latest direction in this area, which will help developers to incorporate such solutions into their research.

“…Therefore, it is important to develop solutions to help PVI improve their mobility, protect them from injury, and encourage them to interact socially [6]. PVI also face challenges when navigating in shops, and to access and identify products [7]. While outdoor navigation is already solved by the use of a global positioning system, indoor navigation is still problematic [8][9][10][11].…”

Identification of Markers in Challenging Conditions for People with Visual Impairment Using Convolutional Neural Network

People with visual impairment face a lot of difficulties in their daily activities. Several researches have been conducted to find smart solutions using mobile devices to help people with visual impairment perform tasks. This paper focuses on using assistive technology to help people with visual impairment in indoor navigation using markers. The essential steps of a typical navigation system are identifying the current location, finding the shortest path to the destination, and navigating safely to the destination using navigation feedback. In this research, the authors proposed a system to help people with visual impairment in indoor navigation using markers. In this system, the authors have re-defined the identification step to a classification problem and used convolutional neural networks to identify markers. The main contributions of this paper are: (1) A system to help people with visual impairment in indoor navigation using markers. (2) Comparing QR codes with Aruco markers to prove that Aruco markers work better. (3) Convolutional neural network has been implemented and simplified to detect the candidate markers in challenging conditions and improve response time. (4) Comparing the proposed model with another model to prove that it gives better accuracy for training and testing.

Grocery shopping represents a challenging task for visually impaired (VI), but the neuroscientific literature on the consumption patterns of this group is still scarce. The aim of the study was to analyse the relationship between explicit consumer experience and neuropsychological measures. A group of VI and sighted explored and manipulated three different product categories inside the supermarket, while EEG, behavioral and self‐report data were collected. Electroencephalogram (EEG) findings showed a generalized delta band activity in pasta compared to frozen food and it was interpreted as higher emotional activation probably required by selecting the correct stimuli in a multisensory environment. A delta band activation was also found in frontal area in VI compared to control and it was supposed to be an index of greater cognitive control. Finally, higher delta band activity in parieto‐occipital and temporal areas were related to greater sense of disorientation. In conclusion, it was found that VI experience grocery shopping more stressfully and with greater cognitive effort (parieto‐occipital area) than people without visual disability. In general, VI use the sense of touch (temporal area) more and have more difficulties in orienting themselves internally in the store. The results could encourage the use of tactile touchpoints, braille maps, or an initial guided exploration of the supermarket, to allow the VI to memorize the internal layout of the different product categories and allow them to shop independently. Another suggestion would be to make products within the same product category more distinctive, perhaps by adding additional tactile information.
