Month: May 2019

This week our team spent all our time implementing our new GUI. This new implementation was tested repeatedly to fix all remaining bugs and issues. Through testing we realized that each sensor had a different threshold. Thus, we decided to threshold on each individual sensor for accurate tap detection.

Future tasks: test our system with the new projector, make the demo video, create an elevator pitch and writing the final paper.

I finished illustrating the GUI and worked with the rest of my teammates to finish updating and debugging the GUI. As a group we also tested out a projector from the library since it is brighter and provides a better user experience. The brighter projection did not affect our system much so we will not need to retrain data thankfully.

Going forward I will work on the final report, an elevator pitch and a video showing how our project works.

We have no significant risks other than unpredictable bugs or extraneous events that occur before our demo.

No changes were made to our existing design.

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.
