Nearly 300 students from across the country gathered for a sleepless 36-hour weekend coding marathon in Hodson Hall, starting the evening of Friday, Sept 15. Teams of up to four students had from 9 p.m. Friday until 8:45 a.m. Sunday to hack together their projects. Using computer vision and object tracking methods, the application automatically alerts users to unaccounted-for objects during the different phases of a surgery. According to the hackers' final presentation, users should be able to deploy the app even in even the most desolate off-the-grid locations. "Even if you can't code, HopHacks is a great way to meet members of industry and acquire knowledge of different areas of computer science."
