Our team used several principles of engineering, science, and math to develop the design solution for our project.
- Engineering Principle: one engineering principle we considered while developing our design was sustainability. We chose components and emphasized through our use case requirements that the device’s power consumption should not be too high and the app’s power consumption on the user’s phone should also be limited.
- Scientific Principle: one scientific principle we used was peer review – one of the major changes we made to our design was based on the feedback we got from our proposal presentation, regarding having the slides pre-uploaded to the app. Peer review is an extremely important part of the design process since it allows for improvement in iterations.
- Math Principle: one math principle we considered was precision, and this informed our decision for which models to select, as well as the change we made to our original idea of using Tesseract directly during the lecture, to now perform text extraction from the pre-uploaded slides.
One major risk is the ML model not being finished in time. However, this risk is being managed by simply working on gathering data as soon as possible, which we also mentioned in last week’s status reports. Our contingency plans include using more data that is readily available on the internet, rather than relying on tagging and collecting our own data.
No major changes were made to the design. However, based on the feedback from the design presentation, we plan on thinking more about the design requirements and fleshing these out for the upcoming design report deliverable. We also had questions about why the glasses were necessary, and whether the audio from the device would be too distracting during class. We thought about this feedback, and we decided not to move forward with any changes — we plan on addressing why these concerns were not extremely pressing, and why we think our product will not fall victim to these issues in the actual design report.
