Totally blind, Daniel learned a new way to see, and he helps others see better. With two masters degrees and a rare ability to navigate anywhere in total darkness, Daniel is the first blind person ever known to be certified to teach blind people how to navigate.

Daniel learned to discern the nature and location of objects well beyond his reach. By clicking his tongue and listening to the patterns of information that echoed back to him, Daniel began to construct images in his mind of near and distant surroundings that allowed him to navigate freely as if he was seeing.

With a ground-breaking brain scan studies were discovered images of Daniel’s activation of his visual cortex. Sound patterns are reflected like camera flashes imprinting his mind with three-dimensional images of his surroundings. With this process, Daniel can recognize an inch thick pole from several meters away, describe his surroundings in vivid detail, and scan the main features of a building from several hundred meters. Daniel’s ears have become his eyes.

During his years in college, Daniel conducted pilot research to develop the first documented methodology to teach what he called “Flash Sonar” to other blind people.

Daniel and his team have presented in TED and numerous science and technical conferences. The revolutionary impact of activation training has been featured in hundreds of media.
