Revise or extend your "hearable" system, and make it interact with other IoT devices (in a broad sense). You may pivot your design if needed. Then go over your (storyboard of) wireframes, and ensure all microinteractions are understood and annotated, and likewise for all exchange of information with other systems/your IoT devices.

Upload one PDF per group 1) containing your revised wireframes (in a storyboard) with a) annotated microinteractions (triggers, rules, feedback) (use draw.io or Lucidchart student account) and b) external interaction. Also 2) update and provide a link to your a executable prototype that demonstrates the main app. Remember to update and include also your revised 3) Lean Business Canvas and 4) User Story Map for the app.
