“…So that, it aims to enhance visual scene interpretation that can establish independent living and foster economic and social self-sufficiency. Yi et al (2013) focus on recent developments in computer vision, digital cameras and portable computers. They refer to the idea that it is feasible to assist blind people by developing camera-based products combining computer vision technologies with existing commercial products such as the optical character recognition (OCR) systems.…”

“…In fact, they combine environment perception with object detection and text retrieval in daily life scene. Among the developed aids for blind people (Tekin and Coughlan, 2009;Tian et al, 2010;Wang and Tian, 2012;Yi et al, 2013;Sàsilva et al, 2004;Yi et al, 2014;Schwarze et al, 2016), a large part is considered as tools of mobility and obstacle detection. Indeed, it can be used only to detect simple patterns and cannot be used as tools of substitution in order to recognise indoor scene.…”

Vision is an essential human sense which is playing the most important role in human perception about surrounding environment. However such information is generally inaccessible for blind people. In order to enable these persons to overcome such incapability, we propose a system for identifying the neighbouring scene. In fact, the environment is labelled as a first step and then we present a personalised and adaptive method for labels detection and recognition. The automatic analysis involves the detection of personalised markers employed to extract the region of interest followed by the perspectives rectification based on homography estimation. We use the stroke width transform (SWT) to extract the text from the detected label and crop it into words and letters. The extracted text is identified using images correlation. Finally, as a substitution for visual modality, a vocal transformation of the recognised text is performed.

“…Research in the field of IoT concept application in indoors are different, from the possibility of providing user assistance to informing systems in the Smart Home environment [5], [6]. In indoor environments, it is also possible to inform users by using a mobile camera and integrating it into the WSN (wireless sensor network) [7], [8], [9]. It is also possible to inform users about the environment and objects surrounding it by using various sensors [10].…”

Movement and informing visually impaired persons is difficult because mobile application solutions and services are unable to work in indoors environments (location based service using GPS technology). Main precondition for active participation in the daily living and needs of visually impaired persons is increased degree of mobility. The aim of this research is to increase the quality of life of visually impaired persons and the degree of mobility in indoor environments by applying modern information and communication technologies (Cloud Computing, Fog, IoT, AAL / ELE platform). User requirement will be used to define functionalities of service for informing visually impaired persons in the example of large retail chains. A conceptual system architecture model will be proposed for providing information service with the aim to provide real-time information to users. This research will also show simulation testing of the proposed architecture with Arduino Uno and Raspberry Pi 3 platforms for collecting information and informing end users.

Access to non-verbal cues in social interactions is vital for people with visual impairment. It has been shown that non-verbal cues such as eye contact, number of people, their names and positions are helpful for individuals who are blind. While there is an increasing interest in developing systems to provide these cues less emphasis has been put in evaluating its impact on the visually impaired users. In this paper, we provide this analysis by conducting a user study with 12 visually impaired participants in a typical social interaction setting. We design a real time multimodal system that provides such non-verbal cues via audio and haptic interfaces. The study shows that such systems are generally perceived as useful in social interaction and brings forward some concerns that are not being addressed in its usability aspects. The study provides important insight about developing such technology for this significant part of society.
