“…The development of EBAT technology with detection and avoidance of obstacles located in the path to be traversed demonstrated a significant reduction in the number of accidental contacts in the travel path and resulted in clear benefits by reducing participants' insecurities, (Abreu et al, 2020). A portable, anywhere-accessible map application to mark obstacles in the outdoor environment such as fallen trees, mud, possible wildlife, and holes (Long et al, 2016).…”

The development of increasingly sophisticated technology is accompanied by the discovery of new assistive devices that should be accessible to all people, including the blind in order to maintain or improve functions so as to improve welfare. This study uses a literature review method with descriptive analysis by analyzing 20 articles. The purpose of this research is to examine more related to assistive technology for the blind in navigating indoors and outdoors including buildings and the accessibility of public services. The literature search was carried out through an electronic search for publications from ERIC, Researchgate, Spingerlink, Sage, Science Direct, Google Scholar and IEEE Xplore. The results of the study describe the use of various assistive technologies for the visually impaired related to navigation in spaces or buildings and even the wider environment as well as public services that are commonly accessed by the public. Furthermore, it is related to the existence of a brief description of the assistive technology developed and the benefits of the results of the development for users.

“…One of the difficulties that blind people have when they walk is to identify if there are obstacles in the way they are going, based on this, the research by [4] proposes a product designed with the purpose of offering optimal protection to the user using his own mobile phone to facilitate its use and reduce costs. The prototype they designed was made with the goal of being worn at chest level, they use two ultrasonic sensors one of them point forward and the other has a downward inclination.…”

As technology advances, a wide variety of devices that aim to help people who suffer from blindness have been developed, since most of the time when this people leave their homes, they tend to be exposed to accidents if they do not have the necessary aid. Therefore, at present, devices have been created either with the objective of leisure such as products that read texts to individuals, also devices made to facilitate the movement of users such as those that make use of sensors or artificial vision and machine learning, even devices that have the objective of monitoring a blind person in case of emergencies, among others. At the same time, the cost of these new technological products is increasing, leading to an increase in the price of the devices used by blind people. This proposed system allows blind people to have access to a portable and affordable device, which informs them by vibrations if there are obstacles in front using ultrasonic sensors. Through a Wi-Fi module and making use of the IoT, acquaintances of the disabled person will be able to monitor their surroundings in live stream or through pictures.

“…Another limitation evidenced in EMA studies is the lack of designs based on user experience, essentially using subjects with temporary vision deprivation (blindfolded) instead of the visual loss being permanent [23]. Taking into account these limitations, this study presents the results obtained for the interaction of different groups of visually impaired with the eBAT (electronic Buzzer for Autonomous Travel) [24]. These have already evolved from an initial prototype applying modifications to the sensors [25] to a stage of improving engineering design.…”

One of the challenges faced by the blind to achieve optimum mobility is obstacles detection and avoidance. The traditional aid is the mobility white cane, but nowadays, there are also electronic travel aids. However, none of them is widely used. The eBAT (electronic Buzzer for Autonomous Travel) has been designed to provide protection and easy usage, interacting with a user’s mobile phone. To improve its performance, a usage test was carried out by 25 totally blind users divided by sex, age range and autonomy in mobility. The main results are that the eBAT gives a reduction in the involuntary contacts but also decreases the walking speed. There are differences between sex, age and mobility groups but with limited statistical significance, and there are also some correlations between variables.
