Risks and Contingency Plans
- Firmware Compatibility Issues : The updated firmware is compilable on different machines and we were able to successfully flash the firmware to the new PCB. However, functional issues may still occur after further testings. So far we have been able to fix the bugs, but if the plan doesn’t work, we would move back to the original firmware and build upon that.
- Model Robustness: We reduced the data collection time of the wand to 1.5s (was 8s). This change was meant to make the device more user friendly. However, model performance became much worse than before even the validation accuracy remains high during training. We are working on capturing more data, and worse case we can increase the data collection time.
- Verification and Validation: We are testing whether the 1.5s data collection window supports accurate gesture classification. Verification focuses on evaluating accuracy, and response time to ensure the model meets MVP requirement. For validation, we are running end-to-end tests to confirm that real user interactions with the wand reliably trigger correct IR outputs.
