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).
I completed design report’s Use-Case Requirement, Technical Requirements, and Testing&Metrics sections in the last past week. To be more specific, in Use-Case Requirement, I detailed the needs of both direct and indirect users. For direct users, I outlined requirements such as the need for real-time audio alerts that enable visually impaired individuals to react to obstacles. This includes specifying alert parameters, like detection ranges and acceptable false negative and false positive rates, to ensure user safety. I also addressed battery life and wearability, emphasizing the need for a lightweight and long-lasting device. For indirect users, such as caregivers, I defined requirements around emergency alerts and GPS accuracy to ensure they can quickly locate and assist users in emergencies. In Technical requirements, I focused on translating these use-case needs into concrete design goals according to the implementation architecture. This included setting benchmarks for the radar’s detection range, accuracy, and response time for audio alerts. I defined power consumption targets to ensure that the device can operate for at least 3 hours on a single charge, addressing efficiency needs without compromising performance. I also specified technical parameters for the fall detection system, including sensitivity thresholds and the maximum acceptable time for emergency alerts to be sent. In Testing&Metrics, I developed a comprehensive plan for verifying the device’s functionality. This involves unit testing individual components like the radar’s accuracy, audio response time, and power consumption. I outlined specific test procedures, such as simulating falls to evaluate the accuracy of the fall detection system and ensuring that GPS coordinates provided in alerts are accurate within a 10-meter range. Additionally, I planned integration tests that simulate real-world use, with volunteers using the device to evaluate its performance in obstacle detection and fall detection scenarios.
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 own progress is on schedule so far, but due to the delay in the progress of each component’s integration, there is a risk that the overall project timeline may be affected. To address this, I plan to allocate extra time for helping in integration tasks in the upcoming week and will collaborate closely with team members responsible for each component to ensure smooth and timely integration. Additionally, I will assist in troubleshooting any issues that arise during the integration phase to prevent further delays. This proactive approach should help bring the project back on track.
Upcoming Deliverables
What deliverables do you hope to complete in the next week?
My goal next week is to support my teammates in system integration and unit tests for each component. While they focus on fully connecting the radar, speaker, and accelerometer with the RPi4 and conducting initial tests to ensure stable operation, I will assist with troubleshooting any integration challenges that arise. Additionally, I will help verify the interaction between components, particularly focusing on validating sensor accuracy and ensuring smooth communication between the devices and the Raspberry Pi. I will also contribute to the unit testing of each component, including checking the radar’s obstacle detection and the accelerometer’s fall detection performance, and I will assist in testing the audio system’s response time.
