This week I focused on running system tests and continuing development of our testing infrastructure for the Focus Field project. I conducted 67 human trials for target lock accuracy with 1–4 users and recorded results, achieving a 77.6% success rate (52/67), which shows the system is functional but still needs improvement. I also performed steering error testing by physically measuring angular offsets using a protractor in a 2D horizontal plane at 1 meter, aligning with our intended use case. In addition, I continued working on our testing suite, including debugging and fixing an issue in one of the automated test files. I also prepared the system for upcoming tests, including interferer suppression and latency, which already have implemented testing scripts.
My progress is on schedule in terms of development and testing, but slightly behind in meeting performance targets, specifically target lock accuracy. However, this is expected during the testing phase as we begin identifying system limitations. Moving forward, I plan to use the collected data to refine the system, focusing on improving accuracy through better alignment and potential algorithm adjustments.
Next week I plan to run interferer suppression and latency tests using the testing suites that are already implemented. I also want to begin intelligibility testing using our defined speech-to-text comparison approach. The goal is to collect full performance data across all requirements and continue improving the system based on those results.
At this stage, I have focused on verifying that individual components of the system meet their defined requirements through structured testing. For target lock accuracy, I verified system performance by running 67 trials and comparing the measured success rate (77.6%) directly against the ≥90% requirement. For steering error, I verified the system’s directional accuracy by measuring angular deviation using a protractor-based setup in a 2D horizontal plane at 1 meter and comparing results to the ≤15° threshold. I have also prepared verification tests for interferer suppression and latency, including implementing and debugging the corresponding testing scripts, although full results have not yet been collected. Additionally, I have defined the verification approach for intelligibility using ASR error comparison, which will quantify performance once executed. Overall, my verification work ensures that each subsystem can be quantitatively evaluated against its specific engineering requirements.
