Thermostat System Iteration 1 – Annotated Wireframes and Task List for “Think-Aloud-Testing”

In Rapid Ideation and Creative Problem Solving we created Concept Model 1 for an existing Honeywell Prestige 2.0 thermostat system and Concept Model 2 as our ideal version of a thermostat system.  By creating these models, we were able to account for what can be done and re-prioritize features and functions to design an ideal system.

We’ve now moved into wire framing, which are visual representation of a user interface showing the behaviors and functionality of a system.  When designing systems – interactions become constrained by an interface enabling communication but is filtered through a limited set of user interface components and controls.

So we began by writing hero flows, which are ideal written stories of how a user interacts with a product, system or service in order to achieve a goal.  The hero flows ultimately helped us frame our task list, which are the sequence of steps the user makes to use a product from start to finish.  And with these set of tasks, I was able to conduct the Think-aloud-testing method to evaluate the usability of my system by encouraging the user to just think out loud as they interacted with my paper prototype of the thermostat system.

Learnings from Think A Loud Testing below:

1. The Menu Tab up top is confusing for the user.  It took a few users a while to understand that this was a tab and not part of the temperature adjustment control

2. Users were unable to schedule temperature and dates for when they would be away

3. Temperature navigation was confusing to interact with – the user did not understand which direction to move when adjusting the temperature

Concept Models 1 & 2

All best,
