What we're seeing in the picture, although it seems a lightsaber taken from a Star Wars movie, is not really meant to be used as a weapon of Jedi combat. Instead, what we see is the replacement for traditional rods, but something far more impressive and useful.
Eye Stick is a conceptual cane uses ultrasonic sensors (similar to what the bats) to measure the distance between you and potential obstacles such as a wall, stairs, etc.. The device is designed to replace the current staff as we have said. Its designer, Kim Tae-Jin, gives us a brief description:
"Eye Stick reinvents the traditional cane. The use of ultrasonic waves to measure the distance to other objects is not affected by rain, fog or other weather conditions. The light projects a stick that is used to avoid possible collisions and reports hazards such as changes in ground level. Eye Stick can also provide information on their products barcode scanning through a camera. The information is then converted to voice. "
Undoubtedly the Eye Stick looks like a stick handy. We hope that someday come true.
