Project Description Smart walker for the visually impaired

Project Description Smart walker for the visually impaired ◦ Four legs with wheels (rollator) ◦ Uses a Kinect camera to provide RGB-D images which are used for depth imaging and creating a point cloud. This gives two different but approximately equally effective methods for determining proximity of obstacles ◦ Haptic feedback is given to the user through varying-intensity vibrations in the handles which signal how close the hazard is ARIAL four-legged walker for detecting unsafe use and prescription compliance ◦ Four legs without wheels but pressure sensors attached to the bottom ◦ Legs sensors give feedback displayed to user on a display mounted on the walker (pictured next slide) to tell them how their weight is distributed among the legs ◦ Also a proximity sensor for detecting unsafe use, such as being too far from the walker which could result in falls NSF REU Research Experience on Internet of Things 2019

Project 1: Io. T-enabled smart mobility devices for aging and rehabilitation REU Students: Kelly Fullin & Nafisa Mostofa Graduate mentors: Sharare Zehtabian & Safa Bacanli Faculty mentor(s): Dr. Turgut & Dr. Bӧlӧni Week 1 (May 27 – May 31, 2019) Accomplishments: ◦ Introduction to machine learning and pandas ◦ Read through and summarized papers of previous work in our lab including the rolling walker with sensors for detecting obstacles and the four-legged walker for detecting safe and unsafe usage as well as prescription compliance ◦ Looked at the walkers from the papers and familiarized ourselves with the user interface Problem & Solutions ◦ I had several questions about the papers which I was able to figure out through rereading or researching and some I will need to ask my mentors about ◦ I am unfamiliar with most of machine learning and artificial intelligence, so I hope to get a better understanding of them in the next few weeks Plans for next week: ◦ Determine specifics of what our project will be ◦ More reading and research NSF REU Research Experience on Internet of Things 2019
