What are aspects to consider when building apps, in general? What are the benefits of adding new input options to our apps? Presenting prototypes that build support for IoT technologies like Amazon's Alexa on Echo and Amazon AWS IoT Button. User Testing is needed to understand the effectiveness of these new types of input.

13. Prototypes allow us to...
1) Materialize concepts
2) Explore functionality gathered through User Research
3) Find answers early with User Testing
4) Iterate towards a possible MVP
→ Quickly, with low cost and low risk

14. Scenario #1 - “Home Sitter”
“I will be away for 3 weeks, on a different timezone. I
want daily updates of what is going on in my house.”
House-sitter agreed to:
1) Feed the dog - Daily
2) Pick up mail - Wednesday and Saturday
3) Let me know if there is a reason we should talk - As needed

18. Scenario #2 - “Home Remote”
“I want to monitor the physical environment in my {XYZ}
house, to better understand living conditions.”
I am using a Zenseio sensor device to:
1) Get home environment measurements
2) Review metrics over time
3) Set up comfort thresholds & get alerts

“Alexa, ask Zenseio for temperature data”
Me at the office
“Alexa, ask Zenseio for {topic} data”
“Alexa, ask Zenseio for highest
temperature on August 21st”
“Alexa, ask Zenseio for week with least
amount of out-of-bounds incidents”

21. Conclusions
1) Investigate aspects of communication
2) Investigate technology to incorporate
3) Decide on most important goals
4) Build them from the start into your prototype
5) Test prototypes with actual users
→ Avoid digital junk
