The Ultrasonic Cover sends out radar waves that can detect objects or people from up to two meters away, then vibrates your phone to let you know something is there. Great for the visually impaired, and also great for anyone who has bonked into a street sign while refreshing Instagram. They are also introducing an Optical Scan Stand (pictured above), which can read text and speak it aloud for anyone who is visually impaired. This would definitely be ideal for people who are more auditory learners, or suffer from dyslexia.
