The concept is yourself Natural light saber. Only it can not be used as a weapon of Jedi, it will perform some other function – namely, this device will replace the cane for the blind to something more the elegant and efficient.
Concept called Eye Stick uses a beam and ultrasonic sensors to detect the distance between a person and, for example, a wall, stairs, or any other obstacle. It was created specifically to replace the standard stick. The device is able to "show" the user a much more comprehensive picture of what is happening around them.
The fact that the Eye Stick uses ultrasonic waves, the device is not affected by bad weather conditions. "Lightsaber" plays a ray of light in order to avoid collisions with pedestrians. Ultrasound system tell in advance about all the barriers and barriers on the way.
Besides all this, Eye Stick can perform another interesting feature – it can get information about any product through barcode, for example. This is done with a special camera that is built into the device. The information is sent via Bluetooth-connection, and is converted to a voice that informs the owner Eye Stick about product details. So far, unfortunately, nothing is known about the date of the start of series production.
