Low Vision

Guide Dogs UK, Future Cities Catapult and Microsoft have teamed up and developed a prototype wearable device that promises to help people with vision disabilities navigate a city.

The device is a headset that pairs with a Windows Phone and uses GPS, cloud based location and a network of Bluetooth and Wi-Fi signals placed along a route. The user will hear continuous clicking, which sounds like it’s coming from a meter or two ahead of them. The clicking will guide them along the correct route. In addition, the application provides information on shops, points of interest and additional details to help the user navigate.

A team of neuroscientist and video game designers from the University of Lincoln, UK and the WESC Foundation, a leading specialist school for children with disabilities in the UK, have been testing a new computer game which may help some children with disabilities lead independent lives.  The game called Eyelander is designed to improve the functional vision of children who have vision disabilities related to brain injury.

White Canes help people with vision disabilities navigate but they are not perfect. They can be cumbersome and miss obstacles that are elevated. Electronic Travel Aids (ETAs) have attempted to address some of these issues. Now, a research team at The Hebrew University of Jerusalem has developed a new ETA call the “EyeCane,” which allows users to better estimate distance, navigate and avoid obstacles.

Currently the EyeCane is designed to supplement the use of a white cane and improve it’s over all capabilities.  In the future, however, it may replace the white cane entirely. The EyeCane currently expanse they capabilities of a white cane by:

  • Adding 5 meters of navigation information
  • Providing information from more angles
  • Eliminating the need for contact

The EyeCane provides information via both auditory and tactile cues. It can provide distance information from two directions. For more information read the ScienceDaily article on the EyeCane.

The Geospatial Information Authority of Japan (GSI) is working with experts to fine-tune software that prints inexpensive 3-D map for people who are blind or have low vision. The maps are tactile and able to be traced with the fingers.

The GSI intends to release the raw data for the maps online. When the data is loaded into 3-D printers roads, railways and other features are raised by one millimeter on resin plates.

New App for People with Vision Disabilities

A new application called SimplEye is equipped with a Braille typing feature and designed to assist people with vision disabilities with all features of their smartphone. The app was launched last week on World Sight Day. The application was developed by Kriyate, a Delhi-based enterprise and was launched by Minister of State for Rural Development Upendra Kushwaha at the Jawaharlal Nehru University. The application is available for download at the Google play Store.

Cavena, a manufacturer of subtitling systems, has partnered with Acapela Group to provide voice for its text-to-speech audio description package. Audio description gives greater access to TV content for people who are blind or have vision disabilities by narrating the action during the natural pauses in the audio. The requirement for broadcasters to provide audio description is growing worldwide and across different media.

Users will be able to choose either the original speaker’s voice in a foreign language or the same content in their own language.

A new textbook for the iPAD that allows children with vision disabilities to experience the stars is the result of a collaboration between astronomers at the Space Telescope Science Institute (STScl); the National Braille Press; and the National Federation of the Blind. Development was funded by a Hubble education and public outreach grant. The textbook for the iPad is entitled “Reach for the Stars: Touch, Look, Listen, Learn” and can be downloaded for free from Apple’s iBooks Store.  

An astronomer from STScl, Eleane Sabbi, collaborated with developers to translate colorful imagery from the Hubble Space Telescope into accessible content that could be perceived by all students including those who are blind and have vision disabilities. The hope is that the textbook will demonstrate that anyone can be a scientist.

IBM is performing research in Brazil that may help customers with visual impairments access information displayed in public spaces. In situations where the layout is constant but content changes like with a vending machine, IBM’s researchers are working on a new method. Instead of focusing on content, which is time consuming and requires a great deal of processing power, they are using some identifying markers placed around the display and simplifying the content’s identification process through training templates.  

The new process can give instructions to customers who are blind or have low vision so that they can capture the correct image. Moreover, this method will allow for perspective correction. Researchers expect the benefits will extend beyond people with disabilities and benefit other consumers.
