What are the most significant risks that could jeopardize the success of the
project? How are these risks being managed? What contingency plans are ready?
- Currently, the most significant risk is going wireless.
- Currently, all of our subsystems are integrated, and the connection between the microphone, voice commands, and web app is wired between a Raspberry Pi and a Raspberry Pi Pico W.
- However, our goal is to go entirely wireless, which is likely the most difficult part so far.
- The contingency plan is to keep the wired connection between this subsystem.
Were any changes made to the existing design of the system (requirements,
block diagram, system spec, etc)? Why was this change necessary, what costs
does the change incur, and how will these costs be mitigated going forward?
- A recent change to the existing design is the introduction of a second Raspberry Pi Pico W. To enhance comfort while wearing the glasses, we found that users preferred balanced designs. So, we are moving our microphone and speaker to a separate Pico W on the opposite side of the glasses.
- There are no significant risks in this choice, however, it is likely that this change will add some weight to the final design. We will carefully consider ergonomics in upcoming user tests.
