● Investigated the need of measuring maker space usage by brainstorming with teammates, researching types of maker spaces, and analyzing interview and survey results● Designed a cheap and adaptable solution using existing resources in a constrained environment, requiring a budget of less than $25 for hardware● Coordinated and led the team with coding a comparative algorithm that analyzed video footage to recognize movement and create a 2D population map of machine usageURLs are provided as LinkedIn does not support animated images.https://i.imgur.com/U9BVG7m.gifThe program was made as a prototype for potential ways to track machine usage in a maker space. It works by comparing individual frames of the input photos (left) and identifies significantly different pixels (right). An overlay is provided for comparison (middle).It also tracks approximately how many people have entered or left by looking for clusters of changed pixels entering or leaving the frame from a chosen direction.https://i.imgur.com/K6tVBFJ.pngThe primary use of the program is the generation of a population map, used to identify the most commonly visited areas by comparing the total amount of times each pixel changes.https://i.imgur.com/8tklNEH.mp4In live testing, the tracking portion of the program worked reasonably well. In this test at Georgia Tech's Invention Studio (recorded with permission), we found a reasonably high success rate for the prototype identifying when people entered or left. The program assumes an empty room at the start, so it reported a negative number when more people left for lunch than arrived.https://i.imgur.com/yhvFCoq.pngThe primary function of the program, identifying areas with the most activity, was a complete success. As expected, the walkways were the most heavily traveled areas and the space in front of the counter had the most activity. The red of the population map overlay was kept light to retain visual clarity of the environment.
