SPECIAL MENTION: Wearable tech may provide more autonomy for millions of people who are either blind or live with uncorrectable vision loss. Ara, a lightweight rechargeable device that uses sensors to detect objects much like a driverless car does, is worn on the chest and can detect obstacles not only at ground level (like a cane) but also at head and chest levels and communicates their location to the wearer through sequenced vibrations.
