Consider ways you can interact with your user around the prototype access and form factors. What should the button look like? Where in the home should it be? What are the “deal breakers” for the needed connectivity, set-up, etc. For the dashboard, what information would an individual want to see daily? Weekly? Monthly? Provide images of the data and let them build the dashboard. *Just like with your ethnographic research, you will want to capture video, photos, and direct quotes.
For the 5E’s, remember for each idea how your user is “enticed”. This is a big hurdle of how you will compel participation. Implementation of ideas is always the toughest part!
