SpecsDetect
Senior Biodesign Project
Overview
Objective
Create a novel proof-of-concept prototype that can help visually impaired individuals navigate the world while walking
Process
Communicated with stakeholders to create customer needs and engineering requirements for the design
Designed sensor holders and housing unit with SOLIDWORKS
Utilized an Arduino as an analog-to-digital converter for the sensor
Reduced noise from the sensor by twisting wires and using aluminum foil for cable shielding
Result
The prototype was able to detect head-level obstacles in a 30° range in front of the user
The prototype can produce haptic feedback with a necklace that vibrates depending on the distance of the obstacles
