This week we improved our pen tracking algorithm by incorporating acceleration data into pipeline. Professor Kim suggested using a weighted algorithm to do this and thus, we were able to implement acceleration data in our algorithm by playing with the weights of the acceleration vs. …
This week we worked on the pen location tracking and the GUI. For the pen location tracking, we got a new IMU and were testing out different software elements to get more accurate readings as we were having issues with accuracy and orientation. We attempted …
This week we worked on the distance module and tried to ensure the accuracy of our own device. We tried to use double integration to calculate the displacement. However, using double integration caused a lot of error which made it challenging to use the pen …
This week, we made significant progress in our pen hardware. We were able to read in data from the accelerometer/gyroscope and send it to our Python code via the HC-05 Bluetooth module. Due to some library issues, we had to pivot to using Windows as …
This week, we met up multiple times to finish the design report and move forward in building our project. We got some good feedback from the professor and TA in details that our project was missing. We are doing our best to turn this into …
This week, we finalized the Design Presentation Slides/speaker notes. We met a few times to discuss the feedback we got regarding our presentation regarding content. This week, we will focus on fleshing out timing measures of the Python code and more specific definitions of inputs/outputs of …
This week we worked on finalizing the design review presentation. We met 4 times this week to talk about the system design and making sure everyone had the same vision for the project. We finalized how each part was going to communicate with each other, …
Overall, we are on track. The biggest risk for our project at the moment is if we mess up some part of our hardware and need to reorder different parts and try again. We decided to mitigate this by buying a couple of parts as …
This week, the most significant risks that could jeopardize our success is ordering the correct parts for our project. Since so much of our project relies on the physical assembly and connection of parts that we have to buy, both time and money could be …
