We expect to hear about the motivation (what problem are you trying to solve?) and your solution as well as future enhancements. For the solution, we want to hear about your idea and see what you did. How you do your presentation is up to you. You may do a powerpoint presentation and put screenshots of your system into the presentation or you may do a demo of your system or both. Or, if you have another idea, that's fine too! However, the presentation must be live (no videos) and everyone should participate in the presentation in some way.
Presentations will be 5 minutes in length. You will be stopped after 5 minutes, so be sure that you have timed your presentation ahead of time.
