Echolocation has been further developed by Daniel Kish, who works with the blind through the non-profit organization [[World Access for the Blind]].<ref>{{cite web |author=World Access for the Blind |url=https://visioneers.org/who-we-are/ |title=Who We Are |website=Visioneers |publisher=Visioneers.org |accessdate=2025-03-05}}</ref> He leads blind teenagers hiking and mountain-biking through the wilderness, and teaches them how to navigate new locations safely, with a technique that he calls "FlashSonar".{{sfn|Kremer|2012}} Kish had his eyes removed at the age of 13 months due to [[retinoblastoma|retinal cancer]]. He learned to make [[palatal click]]s with his tongue when he was still a child, and now trains other blind people in the use of echolocation and in what he calls "Perceptual Mobility".{{sfn|Kish|1995}}  Though at first resistant to using a cane for mobility, seeing it as a "handicapped" device, and considering himself "not handicapped at all", Kish developed a technique using his white cane combined with echolocation to further expand his mobility.{{sfn|Kish|1995}}

Kish reports that "The sense of imagery is very rich for an experienced user. One can get a sense of beauty or starkness or whatever—from sound as well as echo."{{sfn|Kremer|2012}} He is able to distinguish a metal fence from a wooden one by the information returned by the echoes on the arrangement of the fence structures; in extremely quiet conditions, he can also hear the warmer and duller quality of the echoes from wood compared to metal.{{sfn|Kremer|2012}}
