In an office, he feels hot, while she feels cold! Energy is wasted...
The goal of this system is to:
Make everyone feel good about room temperature.
Collects user's data to optimize the temperature and provide precise advice in the future.
Promotes users to select outfits to pre-optimize temperature and give advice.
Provides users the flexibility to create their preferred set of outfit whenever they like.
Shows users the history and record of their thermal preference, their thermal status, and outfit preference.
To engage the interviewers more, thus gather deeper insights and build better empathy, we followed the methodology of participatory design, which resulted in artifacts with insightful user journey as below:
From the interviews, we got the following insights:
INSIGHT 1. Temperature comfort depends on:
Activity (duration of less than 20 min).
INSIGHT 2. In a public space, people seldom change the temperature:
Rarely know how to control over the AC System.
Hesitate to make any changes that may affect others.
Have to bring extra clothings.
Based on the sketch, "what components are needed in the system and how they work together with users?" became critical to be answered. This diagram was both the process (to seek the answer) and the result (aka. the answer itself).
In order to assist users and make users trust the system, adaptability, accuracy and eco-friendliness (save energy) would be the keys. To ensure they are addressed, the diagram was produced to answer questions:
What if no enough outfits are listed?
What if users' reports/ratings are not stable?
Within the temperature range, what degree will be targeted?
We designed, collected feedback, and iterated. The decision processes of two major functions are as below.
(a) Planning the outfit/clothings:
(b) Reporting how you feel:
More details about the iterations can be checked at the Iteration Diagram
Design for Logistic functions like register for offices, linking to schedules and other settings.
Design for multi-platform, like wearable devices, etc.
Make use of diagrams. If something is too complicated to explain and discuss in words, then illustrate it in the form of diagrams as the common ground for collaboration.
Enjoy taking initiative and being bold. During the whole process, I often make "extra" efforts, including elaborating diagrams and figuring out the ways to develop it using Arduino, Framer, and Firebase. Although we did not have enough time to really fulfill that ambition, I have learned a lot through the way and, most importantly, have earned my teammates' trust and friendship.
