Personal Accomplishment
What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
This week, I focused on integrating radar detection with sound alerts, addressing multiple technical challenges. I began by resolving an audio output issue on the audio hat, testing various ports until identifying hw:3,0 as the correct configuration. Next, I adjusted the alert frequency and timing period to ensure the playback that aligns with the original audio file’s rate. I implemented conditional logic to play alerts only when relevant scenario changes are detected, avoiding repetitive notifications and improving usability. I also assisted teammates with detecting and reading data from the accelerometer; we initially worked to convert the C code to Python for consistency with the rest of the project but ultimately decided to continue using C. In preparation for next week’s demo, I refined the presentation of my work to be more intuitive and accessible.
Schedule
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
My tasks are currently on schedule. However, improving the accuracy of both radar and accelerometer detection may require additional time and effort for fine-tuning and testing. It’s also important to address a specific use-case where a high-speed object passes the user; in such scenarios, the audio alert might only have time to announce the object at 5 meters, even if it has already closed in to 1 meter by the time the alert sounds. To ensure reliability in these rapid proximity changes, I plan to explore adjustments to alert timing and prioritization.
Upcoming Deliverables
What deliverables do you hope to complete in the next week?
