General update
- The gantry enclosure is now virtually finished. Trey is working on a way to get the top board to be less bowed when laid on the enclosure so all pieces sit more or less flat on the surface. With that, and a few tweaks for calibration, that subsystem will be complete.
- The LED array circuit works in a 4×4 layout. Tarek finished the code for all the peripherals associated with the Embedded Controller subsystem. All that is left now is to integrate it with the gaze tracking mechanism and wire up an 8×8 LED array. Beyond that, this subsystem needs to be tested and validated.
- Liam is still hard at work on the gaze tracking subsystem. He identified an error in his position estimation calculations, and found a new model which will give us better accuracy and is easily integrated into the existing setup. He also worked on calibrating the webcam
Potential risks and risk management
- The difficulties with getting gaze estimation to work have set us back behind schedule slightly. In order to ensure we have enough time to test a whole system before the demo rolls around, we have set a hard deadline that if gaze tracking is not working satisfactorily by Tuesday night, we will pivot to voice or screen gaze-tracking, which is much easier (and in the case of voice tracking, is already done). This should leave us with enough time to test the whole system end-to-end.
Overall design changes
- No major design changes this week aside from a change in the gaze estimation model.
Schedule
While gaze tracking is behind schedule, the rest of the project is right on schedule and close to being ready for full testing. As previously mentioned, this risk is being mitigated so that a whole end-to-end system can be tested by the time the demo rolls around.
