The Smart Baby Buggy is a sensored baby stroller specifically designed for parents who are blind or visually impaired. Ramona Williams, a woman who is visually impaired, and a team of students from the Department of Bioengineering at Imperial College London, came together to create a stroller that can sense its surroundings and send the user audible and haptic feedback through its handlebar and the accompanying mobile app.
Inside the base of the baby carrier, the Smart Baby Buggy is equipped with ultrasound and Light Detection and Ranging (LIDAR) sensors, which can measure distances between it and other objects using light from a pulsed laser. If these sensors detect any objects or obstacles in their path, they will transmit these signals to the processor which will then relay this information to the vibration motors located inside the handlebar. The handlebar will start to vibrate to notify the user that he or she is approaching an object/obstacle in his path, and the vibrations will increase in intensity as the user draws nearer to it. Then the user can better estimate how far he is from the object/obstacle and maneuver the stroller around it. The Smart Baby Buggy app also alerts the user to changes in ground surfaces (e.g., curbs, drop-offs, corners) with audible beeps via Bluetooth.
The Smart Baby Buggy also features a cradle for the user’s smartphone, a bracket that can hold the user’s cane when traveling with the stroller, and a bright yellow “Visually impaired parent” sign on the front to inform others that the user has a visual impairment.
