NotiFire : Hearing Impaired Alerter System Using Haptic Technology
This project involves designing a low cost haptic device that could help deaf students to be
aware of the situation that will be identified through the research. This research will be using
the tactile technology concept. As we know, nowadays, the world is very focus on
productivity and achievement. Everyone is looking for a job to survive in this world, and this
do not left those with impairment. As they now also been included in the working sectors, the
environment of work place must be examine if it is suitable for them to work in usual
surrounding. By identifying the hazardous situation for a group of hearing impaired that
working in the lab environment
State of the art review on walking support system for visually impaired people
The technology for terrain detection and walking support system for blind people has
rapidly been improved the last couple of decades but to assist visually impaired people may have
started long ago. Currently, a variety of portable or wearable navigation system is available in the
market to help the blind for navigating their way in his local or remote area. The focused
category in this work can be subgroups as electronic travel aids (ETAs), electronic orientation
aids (EOAs) and position locator devices (PLDs). However, we will focus mainly on electronic
travel aids (ETAs). This paper presents a comparative survey among the various portable or
wearable walking support systems as well as informative description (a subcategory of ETAs or
early stages of ETAs) with its working principal advantages and disadvantages so that the
researchers can easily get the current stage of assisting blind technology along with the
requirement for optimising the design of walking support system for its users

Pictures in Your Mind: Using Interactive Gesture-Controlled Reliefs to Explore Art
Tactile reliefs offer many benefits over the more classic raised line drawings or tactile diagrams, as depth, 3D shape, and surface textures are directly perceivable. Although often created for blind and visually impaired (BVI) people, a wider range of people may benefit from such multimodal material. However, some reliefs are still difficult to understand without proper guidance or accompanying verbal descriptions, hindering autonomous exploration.
In this work, we present a gesture-controlled interactive audio guide (IAG) based on recent low-cost depth cameras that can be operated directly with the hands on relief surfaces during tactile exploration. The interactively explorable, location-dependent verbal and captioned descriptions promise rapid tactile accessibility to 2.5D spatial information in a home or education setting, to online resources, or as a kiosk installation at public places.
We present a working prototype, discuss design decisions, and present the results of two evaluation studies: the first with 13 BVI test users and the second follow-up study with 14 test users across a wide range of people with differences and difficulties associated with perception, memory, cognition, and communication. The participant-led research method of this latter study prompted new, significant and innovative developments
Literature Review: Orientation and Mobility Assistive Technology for Students with Visual Impairment
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

Show & Tell What Fun Can Do
ÂUmwelt is a German word meaning Âenvironments, or Âsurroundings. In English, we use the word to describe the world as it is perceived by a given organism. As sighted people, we can only imagine the disconnect that arises when another personÂs Umwelt doesnÂt include sight
Real-Time Obstacle Detection System in Indoor Environment for the Visually Impaired Using Microsoft Kinect Sensor
Any mobility aid for the visually impaired people should be able to accurately detect and warn about nearly obstacles. In this paper, we present a method for support system to detect obstacle in indoor environment based on Kinect sensor and 3D-image processing. Color-Depth data of the scene in front of the user is collected using the Kinect with the support of the standard framework for 3D sensing OpenNI and processed by PCL library to extract accurate 3D information of the obstacles. The experiments have been performed with the dataset in multiple indoor scenarios and in different lighting conditions. Results showed that our system is able to accurately detect the four types of obstacle: walls, doors, stairs, and a residual class that covers loose obstacles on the floor. Precisely, walls and loose obstacles on the floor are detected in practically all cases, whereas doors are detected in 90.69% out of 43 positive image samples. For the step detection, we have correctly detected the upstairs in 97.33% out of 75 positive images while the correct rate of downstairs detection is lower with 89.47% from 38 positive images. Our method further allows the computation of the distance between the user and the obstacles
Interactive Accessibility for the Visually Impaired
To help those visitors with visual impairments access the experiences and content presented in the light area in Launch Pad (a hands-on gallery at the Science Museum London), two exhibit extensions were developed. Exhibit extensions are tools that allow visitors to interact with the phenomena of an exhibit on a personal level. These exhibit extensions dealt with the reflective abilities of light and the color spectrum of light, and allow visually impaired visitors to conceptualize the scientific principles involved through tactile and auditory means. The extensions also bridge the gap in the understanding between those who experience visual phenomena and those whose sight is limited. The design of the exhibits was supported by research into techniques for educating the visually impaired
