Light Stick is a modular stick for the visually challenged that incorporates a lot of good features that make it handy. For starters, it has an obstacle sensor at the end of the stick to alert the user of any danger ahead. The modular handgrip detaches to double up as a scanner and can 'read' and relay back the written text as a voice feedback via the Smart Wireless Headphone. Braille markings ensure that the user can snap back the handgrip correctly. It's details like this and more, that make it a perfect stick!
