Early in the week, we collectively worked on putting together our progress report. We received a lot of insightful feedback from our presentation last week, and applied it both to our report and also our project going forward. In response to this feedback, we have more clearly laid out for ourselves specific implementation details. For example, we have defined exactly what data is sent between each module and how, to make integration more clear, which was suggested to us in the feedback. 

Given the stage that we are at, a big risk to our project right now is being unable to accurately classify muscle movements with the sensors and signals we are currently using, as much of the success of our project depends on our signal processing abilities. The contingency plan that we have in place includes recording more training data, this time with additional electrodes, to increase the dimensionality of the input signal and allow for more feature extraction.

Going forward, we will perform some basic milestone integration testing that we built into our schedule. This will include testing out a basic game in Unity that moves a ball around using binary input from a single electrode. The code for the game can be found here. This way, we can attempt to integrate our entire system with smaller versions of the modules, such that when we have the complete versions it will go a lot smoother. We can also make design changes to the communication protocols earlier on in the process. 

A significant change that we made last week includes changing the number of participants, which is calling for faster design and testing, since we now have to account for the time it will take to collect all necessary data. On the software side, we have started running a little bit behind schedule, and on the hardware side, we are about a 1.5 weeks behind. Our full schedule is available here. We will work considerably harder this week to compensate for the lost time, as well as having used our Phase 2 slack days. We are starting to enter Phase 3 of our project, which includes going from a basic system with a single electrode to a fully implemented system.
