INTER, the Thermostat for Everyone
Design of INTER thermostat is for Interaction Design Practice class.
Design with co-worker, Kayla Cooper.
Our design process.
Some early concepts for the design and more brain mapping.
Together, we brainstormed a complex thermostat versus a simple thermostat. We took into consideration our personas, factors outside the users, and utilizing different features to fulfill the project requirements. We agreed that a multitude of features would be disadvantageous in this project.
We chose to utilize materials such as foam and wooden sticks in order to demonstrate how tactile feedback would tell the user that extreme temperatures would make the slider more difficult to push. For items like the dial and screen, we went with the more traditional paper prototyping methods. Narration during use of a completely paper prototype would not give the user the same experience and the tactile response is a very important feature of our thermostat. It is paramount to the experience that the user understands this feature. The tester might not feel the same if he or she were to be only told how the response works; he or she would have to use their imagination.
The main appearance of the thermostat redesign. The black interface does not create a lot of light during the night and it is optimized for users with visual impairment.
The thermostat is being turned up to 72°F, which is a cost-efficient temperature when set to cool mode.
However, 60°F is not optimal for the summertime, so the green interface fades into black and gives the user a warning. The severe change to black has been optimized for the colorblind and for the visually-impaired. Both types of users can understand the change from a green hue is not optimal. Tactile resistance also aids the user.
After five seconds of setting the temperature, the thermostat will fade to a new screen that indicates how many minutes it will take to reach that temperature. We hope that by showing the user that it takes a shorter time to reach more eco-friendly temperatures, they will be more likely to choose those temperatures.
This indicates an eco-friendly range when the heat is being used.
However, when the heat is set too high, it will warn the user through a message and tactile resistance.
