Guide dogs are expensive to train, so robots could provide a cheaper alternative to help people who are blind

Google has announced one of its upcoming apps called Lookout as part of the annual I/O conference, and it has nothing to do with the mobile security application of the same name. The tech giant's Lookout was designed to help the blind and the visually impaired be more independent by giving them spoken notifications about their environment. For instance, it can tell them that there's a "chair 3 o'clock," so they don't bump into the object to their right. The app can also read texts, such as Exit signs over doors. The application has four modes to choose from: Home, Work & Play, Scan or Experimental.

The white stick is getting a 21st century makeover - by becoming a wearable. Japanese car firm Toyota has designed a mobility device worn over a person's shoulders that can help blind and visually impaired people get around more easily. Called Project Blaid, the device is currently a prototype, but when it's ready, it'will fill the gaps left by canes, guide dogs and basic GPS devices by giving users more information about their surroundings,' the company explained.

Named Project Blaid, the gadget is worn over a person's shoulders (pictured) and can help navigate indoor spaces, like offices and shopping centres by pointing out features like toilets, doors, stairs and escalators The gadget is not expected to replace guide dogs or other ways blind people get assistance, but instead is designed to enhance the current methods.
