Here is a cool wearable device that could help you read printed text easier. The FingerReader is designed to assist the wearer in reading printed text. It is useful for visually impaired folks but could help everyone else too. The wearer gets to scan a text line with their finger and receive audio and haptic feedback.
The FingerReader algorithm can detect and provide feedback when the wearer is moving away from the baseline of the text. In other words, it helps the wearer read in a straight line. This can turn into a real product in the future.
