This week I finished the verification of the LED subsystem. I tested the remaining 3 full games for the move suggestions and the 30 board states for the latency and move suggestion accuracy. These last three games ended up having 99% average accuracy and 185ms average latency, which meets the <200ms metric we were aiming for. I also added tests to tell the latency between when the chess engine send an API request to the LED subsystem to turn on the opponent’s moves and when the LEDs are actually turned on. This is in addition for the 7 full games and 70 board states I collected last week where we had slightly less accuracy at 98% and also around a 185ms average latency. We did not make any design changes after the analysis of these test results since these meet the metric we were aiming for and we thought the experience of playing the game was how we envisioned. One thing we did talk about adding is a button for when the player is done making either their move or the opponent’s move so that the LEDs could be turned off for the CV, which hasn’t been trained with the LEDs lit under the pieces.
My progress is on schedule. Next week, I hope to finish the report and poster to be ready for the demo.
