“…Scenarios where obstacles are located more than 1.5 m away or are not directly in the person's trajectory, such as those on the side or above, are labelled as negative. The distance of the label is based on the established literature in similar studies for BVI individuals [33,34].…”

Individuals who are Blind and Visually Impaired (BVI) take significant risks and dangers on obstacles, particularly when they are unaccompanied. We propose an intelligent head-mount device to assist BVI people with this challenge. The objective of this study is to develop a computationally efficient mechanism that can effectively detect obstacles in real time and provide warnings. The learned model aims to be both reliable and compact so that it can be integrated into a wearable device with a small size. Additionally, it should be capable of handling natural head turns, which can generally impact the accuracy of readings from the device’s sensors. Over thirty models with different hyper-parameters were explored and their key metrics were compared to identify the most suitable model that strikes a balance between accuracy and real-time performance. Our study demonstrates the feasibility of a highly efficient wearable device that can assist BVI individuals in avoiding obstacles with a high level of accuracy.

Frequentemente os portadores de deficiência visual se deparam com objetos durante seus trajetos e esses são os principais causadores de acidentes por colisão. Para amenizar esse problema diversas pesquisas desenvolveram soluções capazes de detectar obstáculos, no entanto muitas como as que usam bengala são ineficazes para diversos cenários, com limitações na percepção de obstáculos, além de ocupar uma das mãos. Este artigo apresenta o desenvolvimento de uma nova solução vestível, que é o BlinGui para detecçãoo de obstáculos estáticos em ambientes internos. Dispositivos vestíveis tem a vantagem de funcionar sem o uso das mãos, além de ser observável e controlável. A avaliação desta solução teve em média 90% de resultados positivos.

“…This is an installed system of network that enabled the cane to read their proximities and deviate from obstacles. Other applications of ETAs incorporate immediate obstacle detection technology by distance using simple sensors like ultrasonic and infrared (Shoval et al, 2003;Rey et al, 2015).…”
