A “smart shoe” that allows people with visual impairments to walk without a cane

That’s why he set out to create a discrete device, so they feel more comfortable and that’s how the shoe came.

The shoe has three ultrasound sensors placed inside the sole – in the frontal, lateral, and back areas. The sensors emit ultrasound waves, which are reflected by surrounding objects and come back to the sensor. The shoe vibrates depending on the distance and position of the objects. The shoe is battery-powered and detects objects of all kinds: Plastic, concrete, metal, marble, wood, fabric, glass, person, door beams, animals, cars, beds, trees, etc. within a 25-inch (63.5 centimeter) radius of the wearer.

The device can be recharged with a USB port via computer or with a cell phone charger. It takes about five hours to fully charge, and it’s good for three to four days.
