Helping the blind get around used to involve audio cues at street intersections as well as having the assistance of a cane. Well, things have certainly progressed to a greater level today thanks to an associate professor of applied science at the University of Arkansas who has been working on a white cane which utilizes laser technology in order to deliver the lay of the land to users. A Flash LADAR (laser detection and ranging) three-dimensional imaging sensor will be the main star behind recreating a detailed model of the user’s environment. It is capable of taking in just about everything simultaneously, within sequential floodlit exposures that typically lasts less than a nanosecond each, making it suitable for those who are always on the move. Hopefully a hypothetical navigation device will become reality in due time.
