Jenny Han, Bradley Zhou, Jade Wang. Carnegie Mellon ECE Capstone, Spring 2021
This week, I worked with Bradley and Jenny to refine our pen tracking algorithm such that it incorporated the accelerometer data. We decided to use a weighted approach since the accelerometer data exaggerates any errors in distance calculation. I also worked with Jenny to add …
This week, I finished fully automating the process of adding a new gesture with the GUI. The GUI page now refreshes automatically to display the newly added hand gesture and the user macro that it maps to. Additionally, we decided to alter our approach for …
This week, I worked on automating the hand gesture recognizer so that users can add new gestures and map them to user macros. The program now will take in the new gesture readings and automatically train the model immediately. The program then restarts automatically so …
This, week I worked on both the pen tracking algorithm and the hand gesture recognition algorithm. For the pen tracking algorithm, I tried out a Kalman filter for the acceleration readings from the MPU6050. I tried various parameters but it seemed like the Kalman filter …
This week, I worked with Bradley and Jenny to improve our pen tracking algorithm. We tried several methods to ensure the accuracy of the device. However, we ran into issues with the double integration and found that the error was magnified with integration. This week, …
This week, I met with Bradley and Jenny several times to make progress in our pen hardware after meeting with Professor Kim on Monday. After Bradley assembled the initial pen hardware, we all met up to help debug his assembly on the breadboard. We explored …
This week, I worked on finishing our Design Report Document and turning that. Additionally, I worked on the Python script to read data from Bluetooth data from the HC-05 module. I experimented with the PyBluez library and found several complications with the library and its …
This week, I finalized the Design Presentation Slides, wrote speaker notes, and practiced/rehearsed my presentation. In doing so, I flushed out more details regarding metrics and validation with Jenny and Bradley. We received a lot of in-depth feedback for our presentation regarding content. Something important …
This week, I met with Jenny and Bradley to refine more of our project details surrounding our testing, verification, and metrics after getting feedback from Professor Kim. We also ordered our parts and they should be arriving soon. I also did some research on the …
This week, I researched the Arduino Pro Micro and HC-05 Bluetooth module compatibility. I looked into which pins should be connected to connect the two parts. I also created a Google Sheets to document our planned budget online. Additionally, I met with Jenny and Bradley. …
