At the beginning of this week, our group did a demo of our project, and we got a lot of useful feedback. Byron suggested including simulated data as a part of our training data. This data would come from taking the ground truth of the signals from each muscle movement and adding noise to it. After receiving that advice, I worked on defining the “ground truth” signals of our data, by analyzing the output of our test data and averaging…
This week I created animations for the main character for running and jumping. I used Unity’s State Machine to trigger jumping motion from the default state, which is the running state. The Unity Asset for characters do not come with animations, but they do come with customizable joints angles that I can manually create animations. So I made a running motion and looped the animation to make the character running. Another major achievement this week is that I was able…
This week our team presented a demo of our project to our TA and professor. The main components of the project that we demonstrated were the relatively complete subsystems of the hardware EMG data collection and the software system visuals of the game. The final subsystem of the project that is in progress is the signal classifier. We got feedback from Dr. Yu that we can generate simulated signal data in order to verify the functionality of our classifier without…
At the beginning of the week, we discussed ethics and how it relates to this class, which got us considering it in the context of our project. We were able to consider the ethical implications of our project and the kind of politics driving a need for it/the politics it would catalyse with its creation. Also in the beginning of the week, we met to discuss what we had learned from integration test #2, and talk about what we should…
This week I setup the design for infinitely generating obstacles with appropriate distances between obstacles. One major requirement is that the game cannot be impossible, and to do this distances between obstacles need to be far enough so that after one jump over an obstacle, the user can have enough time for the next jump. To have a consistent spaces between obstacles, I decided to have 3 different pools of obstacle sets – easy, medium, hard. Each obstacle sets are…
This week we did Ethics discussion about our project. While discussing about how technology projects have ethical side effects, we got to think about how our project can impact the way we expect to be, and the way we don’t expect to be. Ideally we want Myorun to be used by enthusiasts who would like to try out a fun game without touching controllers, or perhaps people who need to use arm muscles for rehabilitative purposes. But we also got…
This week for capstone I spent the majority of my time organizing the classification algorithm approach to our EMG data. A major decision factor going into this classification of the data depends on how the data is recorded. I found that if the data is recorded in a continuous stream of repeated actions, the best approach is to use wavelet transform on the data in order to identify a basis function and the scaled and shifted versions of it. This…
This week I bought a texture pack from Unity Asset Store to bring in better look and feel in to the game. The new asset contains more diverse objects to create obstacles and background. The old terrain and structure is replaced with the new texture pack. I also fixed the lighting and fog issue where distant objects are grayed out. Graying out distant object can be good as it makes the game more realistic, but previously the gray distance was…
This week the data collection process was bolstered and thanks to Tarana’s hard work in coordinating the hardware system of the EMG, we were able to collect data recorded from more than a single electrode. Last week’s milestone was collecting data from a single electrode and visualizing the signal from different recorded movements over time. This week, toward the end of the week we got data collected for all the movement collected from five electrodes on the forearm. This upcoming…
This week we caught up to our Gantt Chart and got ourselves back on schedule by performing the first two integration tests. Using Kayla’s thoroughly researched experimental protocol, Tarana was able to record data for both a single electrode and an array of electrodes, and play the games that Alex has been working on the past few weeks. Our first integration test featured a single electrode and a very basic game that involved moving a ball around, which was designed…
