In­no­va­tion of the week

The Week (US) - - 18 News - A new smart wrist­band aims to give the vis­ually im­paired a “sixth sense” to help them move around, said Pe­ter Holley in

The Wash­ing­ton Post. Some 7 mil­lion Amer­i­cans live with a vis­ual dis­abil­ity, and most rely on canes or guide dogs to help them nav­i­gate haz­ards.The Sunu wrist­band uses echolo­ca­tion to no­tify the wearer of nearby ob­jects.The de­vice “emits a high-fre­quency sound wave that bounces off ob­jects as far as 14 feet” away and then reg­is­ters the ob­jects’ lo­ca­tion with a gen­tle, puls­ing vi­bra­tion on the wearer’s wrist. “The closer the ob­ject is—whether it’s a wall, trash can, or per­son—the more fre­quent the pulses be­come.” Set­tings such as pulse sen­si­tiv­ity can be cus­tom­ized via an app. De­vel­op­ers hope to con­nect Sunu to map­ping apps, al­low­ing users to re­ceive in­for­ma­tion about their im­me­di­ate lo­ca­tion.
