Problem
Climate change
Climate change can lead to electricity shortages as extreme weather events such as heatwaves, droughts, and hurricanes can damage power infrastructure, disrupt the functioning of power plants, and impact the transmission and distribution of electricity.
Energy Crisis
More than 65% of the energy produced in the United States is being wasted or lost due to inefficient systems, outdated infrastructure, and inadequate energy management practices.

Energy waste in school
The U.S. Environmental Protection Agency (EPA) estimates that schools could save an average of 25% on energy costs by implementing energy-efficient measures and adopting sustainable practices.

Insights
-
People of high consumption should take more responsibility for saving electricity.
-
Essential electricity consumption items can not be reduced, but need to reduce the amount and length of electricity consumption.

Individuals' electricity-saving behavior has significantly raised global energy and electricity shortages.
-
Social environment, family education, seasonal factors, and students' lifestyles can affect electricity consumption habits.
-
Misunderstanding leads to weak awareness of power saving.

Concept
Gamification
APP + Device,
which inspires college students living in school dormitories to save electricity and assist them in establishing long-term energy-saving habits.
Key Features for the APP
Gamification: Seize the points from the users who overuse the electricity
Gamification: Turn off the light in AR perspective
Incentive mechanism:
Points ranking
Rewards: Exchange merchandise with points
Key Features for the Physical Device
Data Visualization
Displaying the electricity usage of each individual in the dormitory clearly. Serving as a warning and encouraging competition among fellow students.
​
When you overuse the electricity, you will be exposed to the risk of reducing the points which will be ranked and rewarded.
Frameworks
Turn off the lights
When the light in the empty room is on, students can see it from the AR perspective. They can turn off the light in the game and get points as resard.
Seize the points
When the resident in the room overuses the electricity, the indicator light​ out the door will be on, which means this resident may have the risk of losing some points. The direction of the room can be shown in the app. If other users find the light, they can seize the points from the resident.
Iteration
User testing
Evaluation
-
It is hard to notice the Seize button on the homepage.
-
When exchanging the reward, it is easy to press the medal instead of the More button
-
On the homepage, it is confusing what is the meaning of 50% when the users first used the application.
-
When turning off the light, most users click the light instead of the focus frame
Iteration
Final Work
Key Feature 1: Seize
White light means the left amount of your target electricity usage;
Green light means the resident overuses the electricity, and other uses can seize his or her points now.
Different status have different meaning.
The indicator light in the enviornment of the dorm.
After Seize
Key Feature 2: Turn off AR light
Key Feature 3: Turn off AR light WIHT FRIENDS
When someone finds a double-point light, you may get a request to help him or her in the vicinity.
When you come and turn off the light with your partner, you two will both get double points.
When you find a double-point light, it will send a request to the person in the vicinity.
When your partner comes and turns off the light together, you two will both get the double points.
