SensStep

The smart shoe for autonomous and safe mobility for blind or visually impaired individuals.

A multidirectional ultrasonic sensor is used on the SensStep, inspired by the obstacle detection technology used in smart cars, to provide 360-degree environmental awareness. This allows visually impaired users to navigate safely by sensing obstacles in all directions in real-time through located vibration on the mesh.

The sensor is connected, through smart wires, to an external small battery. I decided to connect the battery to the the sensor through an external system for safety purposes.

To reduce injury risks, especially for elderly users, I have incorporated an engineered laceless mesh that offers comfort and a secure fit at the front of the foot. Traditional laces, if improperly tied due to vision impairments, might lead to unintended injuries.

I also integrated a new heel tab reinforcement design to prevent ankle sprains in case of accidents—though such incidents should be significantly reduced thanks to the ultrasonic sensor's obstacle detection.

The EVA cushioning foam for shock absorption helps prevent hip and other injuries.

The rainbow colors is used to express that joy can be found into eternal darkness.

“Fearless” is written in Braille, the written language of the blinds, in silicon 3D screen print for the user to feel the purpose of the SensStep
