Abstract The purpose of this project is to allow a visually impaired person to enjoy playing the sport of basketball in his/her driveway or yard. The project required adapting a portable basketball goal system so that a visually impaired person can experience this sport. The assistive technology developed consisted of instrumenting the pole with a custom built beacon to allow the person to know where the portable system is located, thus determining in which direction to shoot the basketball. The beacon, mounted on the pole, emits a continuous distinct beeping sound. Also, the hoop was instrumented with a sensor that allows the person to know if he/she makes a basket. A sound is triggered to signal when the basketball passes though the hoop successfully. Furthermore, the hoop was custom sized to increase the odds of making a basket.

This paper reports on the progress of a wearable assistive technology (AT) device designed to enhance the independent, safe, and efficient mobility of blind and visually impaired pedestrians in outdoor environments. Such device exploits the smartphone’s positioning and computing capabilities to locate and guide users along urban settings. The necessary navigation instructions to reach a destination are encoded as vibrating patterns which are conveyed to the user via a foot-placed tactile interface. To determine the performance of the proposed AT device, two user experiments were conducted. The first one requested a group of 20 voluntary normally sighted subjects to recognize the feedback provided by the tactile-foot interface. The results showed recognition rates over 93%. The second experiment involved two blind voluntary subjects which were assisted to find target destinations along public urban pathways. Results show that the subjects successfully accomplished the task and suggest that blind and visually impaired pedestrians might find the AT device and its concept approach useful, friendly, fast to master, and easy to use.

Visual impairments often pose serious restrictions on a visually impaired person and there is a considerable number of persons, especially among aging population, which depend on assistive technology to sustain their quality of life. Development and testing of assistive technology for visually impaired requires gathering information and conducting studies on both healthy and visually impaired individuals in a controlled environment. We propose test setup for visually impaired persons by creating RFID based assistive environment – Visual Impairment Friendly RFID Room. The test setup can be used to evaluate RFID object localization and its use by visually impaired persons. To certain extent every impairment has individual characteristics as different individuals may better respond to different subsets of visual information. We use virtual reality prototype to both simulate visual impairment and map full visual information to the subset that visually impaired person can perceive. Time-domain color mapping real-time image processing is used to evaluate the virtual reality prototype targeting color vision deficiency.

There are many issues over which humans have no control. Blindness is one of such issues. It snatches the vivid visual beauty of the world from an individual’s life.But missing the beauty of nature becomes one of the last worries of such people as they have to face numerous difficulties in order to perform even the most basics of tasks in their day to day life. One of their most important problems is of transport, such as crossing roads, traveling in trains, or in any other public places. A visually impaired person to survive the fittest in this world, the person must go through all the obstacles without the guidance of others. One of the most important measures to avoid the obstacle by the blind is to provide an assistive implementation, which can help to wander on their own. The main aim of this project is to provide an assistive technology used for the purpose of enhancing the mobility of the blind pedestrian which is commonly referred to as Electronic Travel Aid (ETA) and to motivate the blind without having the inferior feeling of their problem and pay away the blind to move on their own . In this project, a smart guiding ETA is used to guide the user to sense the obstacle before them. This device eliminates the requirement of human assistance for blind while traveling outside. It will identify all obstacles in the path with the help of various sensors installed in it. The microcontroller will retrieve data and pass it on as vibrations which will notify the user about hurdles.

Abstract In the article I present an ethnographic reflection on the process of guide dogs generation, an animal assistive technology developed to facilitate the mobility of the visually impaired person. Focusing especially on the training phase, I try to understand the trajectory of transformations, the unfolding of events and the changes of movement that make certain dogs able to "graduate" as guides. Following a Maussian perspective, the guiding technique is understood here as the result of a certain relationship between movements and things, encompassing tools, human and canine bodies and their displacements in different environments.

As life expectancy increases, the number of people who suffer from blind and visual impairment due to presbyopia is gradually increasing. Assistive device systems have been used to overcome various physical, social, infrastructure, and accessibility barriers. As technology has advanced, the scope of assistive technologies has been expanded. Therefore, we explored technological opportunities in assistive technology for the blind and visually impaired to establish a strategy for the technology competition in the near future. Firstly, the patent vacuum is detected by generating the patent map based on generative topographic mapping (GTM). Secondly, social network analysis is applied to identify the relationship between patent vacuums and occupied grid points in the patent map. Finally, the technology activity index and technology impact index are considered at quantitative and qualitative levels. Consequently, it was identified that wearable devices, including the road situation signal acquisition module and data acquisition process control module, could be occupied in the future. This study can provide practical ideas for research and development (R&D) in the field of assistive devices for the blind and visually impaired. In addition, this study can be an ample source for decision/policy makers to project new contents.

In this paper, we have given the design and development of a new wearable device that assists visually impaired individuals to travel independently and confidently. The newly proposed device is based on range-based sensors and would work effectively in both indoor and outdoor conditions. It is constructed in the form of two separate modules; one module is designed such that it can be attached to the waist belt of the user, and the other module is designed to wear it on ankle of the user. Both the modules communicate with each other using wireless communication and can cover the full front environment of the user. The information about the front environment is transmitted to the user, via headphone, by sending a set of voice instructions, stored in a memory card added in the belt module. In order to use the device in crowd mode, appropriate networking techniques were also implemented in the prototype such that the interference of two or more devices in the close vicinity can be avoided. In the end, effectiveness of the device is analyzed and proved by conducting experiments and obtaining statistical results.

The Ideal

One of the ideal public transportation facilities for the visually impaired in daily activities is trains. To be used at maximum, there is a need for communicative media to support the independence of orientation and mobility for the visually impaired in the train station. The media plays a role in supporting visually impaired individuals to know where they are, where to go, and how to reach the destination. The previous result regarding visually impaired ability to identify pictorial form which is designed with Primadi Tabrani’s ancient visual language semiotic approach shows a great opportunity for a pictogram to be the solution. However, the challenge is how to make the visually impaired person understand the meaning description that has been designed into tactile pictogram by touch. Basic consideration in designing process is the clarity of visual form when being touched, which is influenced by the way the shape is drawn and the tactile height
