InnoMake is a shoe designed by the Austrian startup company Tec-Innovation. Each shoe comes equipped with front-mount light sensor. When it detects an upcoming obstacle, it warns the user with a vibration and a cellphone notification delivered through a Bluetooth connection. The product website explains how it works:
The vibration feedback is provided directly in the shoe, which allows you to feel if there is an obstacle in front of you. The acoustic feedback is provided via a smartphone and if required via e.g. bone conduction headphones so as not to drown out environmental noises.
The visual impulses can be transmitted via the LED on the shoe and they can provide you with additional support in the dark. You can also use InnoMake without primary tools in familiar, safe environments, e.g. at home or at work, so that both hands are free.
