Electronic Travel Aids (ETAs) improve the mobility of visually-impaired persons, but it is not easy to develop an ETA satisfying all the factors needed for reliable object detection, effective notification, and actual usability. In this study, the authors developed an easy-to-use ETA having the function of reliable object detection and its successful feedback to the user by tactile stimulation....

Vision impairment or low vision is the disability to see any objects clearly. It might be caused by old age, an accident, other neurological condition. People find it difficult carry out their regular activities, regardless of cause blindness. As medical researchers are working a cure for blindness, contrariwise using technology make person’s life easier in affordable way. result, smart cane wa...

We determine the region in front of a walking person that is not blocked by obstacles. This is an important task when trying to assist visually impaired people or navigate autonomous robots in urban environments. We use conditional random fields to learn how to interpret texture and depth information for their accessibility. We demonstrate the effectiveness of the proposed approach on a novel d...

As to the human computer interface for the visually impaired people, there are two models a vision-based indoor navigation system can be used. First, if a visually impaired person wants to know the current location, it calls the application of a smartphone or wearable device and finds out the current location. Second, the system automatically sends notification to the users if they reach a spec...

It is well known that visually impaired children have limited opportunities in learning new things compared to normal sighted children as visually impaired children do not have one of the important senses of human being. Computer simulated virtual reality environment can provide better opportunities for visually impaired children especially in learning the shapes of new objects. An application ...

Access to simple visualisations such as bar charts, line graphs and pie charts is currently very limited for the visually impaired and blind community. Tangible representations such as heat-raised paper, and inserting pins in a cork-board are common methods of allowing visually impaired pupils to browse and construct visualisations at school, but these representations can become impractical for...

Nearly 5% of the US population is visually impaired, and nearly half of this population is within ‘working age’ (18-69). In humans, the visual sense is the most important of the five senses, and a lack of it poses serious limitations, both in daily life activities and also in job placement. The most basic task enabled by the visual system is the navigation of spatial environments. More advanced...
