This week we finished our poster board. We also finished our new gui design. We spent most of the week debugging the new interface and repeatedly testing our system.
When testing our system in the gym, Suann and I found that the projected gui was difficult to see due to the very bright ambient lighting. We borrowed a projector from the library. This projector works much better in daylight so we decided to use that for our final demo.
There were some issues with one of our piezo sensors. We were reading a very high value from one particular sensor, which led to several false positives detected from our tap detection subsystem. We were able to bypass this issue by creating separate thresholds for each sensor. Now, the first four seconds on startup of the system are used to determine the average value read by each sensor when the system is at rest. This value is used to determine the threshold value for identifying a tap.
We also worked on our final paper this week.
Next Steps:
Finish the final paper.
We are on schedule.
