Vision processing eyeglass-mounted device helps the visually impaired

The processor’s integrated camera interface reduces the end-product form factor by eliminating the need for additional components, and the chip’s advanced power management capabilities provide exceptional power efficiency for long battery life.
The OrCam product is comprised of a small unit mounted on the wearer’s eyeglasses and includes a small camera, microphone and bone conduction headphone. Designed with an intuitive user interface, the wearer simply points at an object or text with his or her finger, and the device then interprets and reads it.
The i.MX 6Quad processor integrates four ARM Cortex-A9 cores running up to 1.2 GHz, delivering the processing performance to handle the massive amounts of data captured by the OrCam product’s visual sensor. This performance allows execution of all processing algorithms and software speech codecs on a single chip. i.MX 6Quad processors support computer vision algorithms that allow OrCam to recognize a broad range of inputs, from the faces of friends who walk into a room, to text in newspapers and books, to transit signs, traffic signals and everyday objects of all sorts.
“The i.MX 6Quad processor delivered outstanding performance well within the power envelope we needed to design a wearable, affordable and intuitive solution for people whose visual impairments prevent them from easily interacting with the world around them,” said Amnon Shashua, co-founder of OrCam and the Sachs professor of computer science at the Hebrew University. “With Freescale’s highly advanced i.MX 6Quad device, OrCam is able to help compensate for lost vision and dramatically improve quality of life for the visually impaired.”
