Deliverables

How can we extend and maintain University of Washington students’ personal device battery life while on campus?

Dawg Power is a HCDE student led case study and design project exploring how University of Washington students currently use and maintain their technological device charge on campus. Our clients are UW students that use any rechargeable devices such as a laptop or mobile device throughout their school day.

How can we extend and maintain University of Washington students’ personal device battery life while on campus?

  • How long does a fully charged device typically last students?

  • What do students use personal technology for? 

  • Are there specific locations on campus where students find it more challenging to access charging outlets or stations?

  • How are students currently addressing charging needs on campus?

  • What effects does a personal device dying on campus have on students?

“Yesterday I was hanging out on the HUB lawn in between classes texting a friend, and I realized that my phone battery was draining quickly. My phone died right before it was time for me to walk to my next class, but since I’m new to UW, I don’t know the campus well so I didn’t know how to get to my next class without my phone. I ended up being late to class because of that.”

Need to use devices while charging

“Last week I was studying for my statistics midterm in a library on campus when my computer went into low power mode. Even though I had my charger with me, there were no outlets around. So I packed up all my stuff and walked across campus to a new library, interrupting my study session. When I got to the new library there was no tables near outlets, but I could not waste more time, so I sat on the floor by an outlet.”

Ability to charge devices while on-the-go computing from class or between study areas on campus

The ability to charge devices when relocating to different study spots regardless if there is a outlet available

Ability to charge devices while simultaneously using them regardless of physical location

At around noon, Kam enjoys lunch at the HUB while scrolling through social media on their phone. After, they walk to their class in Red Square listening to music.

Kam gets a notification and notices that their phone is in low battery mode. This indicates that the phone battery is less than 10% and will die shortly.

Outside of Mary Gates Hall on the way to class, Kam notices a vending machine called Husky Charge that prompts the user to rent out mobile or laptop portable chargers.

Kam precedes to check-out a portable charger for their phone by swiping their husky ID card. This portable charger + charging cord is then rented out for them to use while on campus.

Upon connecting the portable charger and their phone, a screen pops up indicating the time of battery check-out, portable charger life, location of battery and vending station and the charging capacity the portable battery holds.

Kam made it to their class and is taking notes on their laptop in a crowded lecture hall while simultaneously charging their phone off to the side.

Wireless Magnetic Portable Battery

Dawg Power App

Renting Battery Station

Dawg Power is a on-campus free portable charging system accessible to students currently enrolled at the University of Washington. Our rentable portable batteries are compatible with any desktop and mobile device by using electromagnetic induction charging (pass-through technology). Users with low battery no longer need to deal with plug-in chargers or finding outlets around campus with Dawg Power.


How does it work?


Step 1: Download our Dawg Power app

Step 2: Find a Dawg Power station on campus

Step 3: Rent out a portable battery using your UW Netid or with a Husky id card

Step 4: Track your devices' charging status, station locations, and academic schedule with the app

Step 5: Return your battery to a station before you leave campus

TEST

Usability Testing

  • We separated the battery level bars per calendar event to clearly indicate device charge throughout the day to create better readability for users.

  • Created visual instructional models for critical renting rules prior to battery checkout on the kiosk so that users clearly understand renting and returning logistics.

  • The user can simply select an event on the schedule, and an “adjust usage” popup appears to edit their device hours. Time can be adjusted with a scrolling interface.

Based off of user feedback, here are some changes that we made:

5 pre-test questions

3 interactive tasks

5 post questions

Reflection

Check out more work!

Useful methods: We implemented a team contract every 3 months (2 total) throughout the project to define roles, expectations, and solidify deliverable timelines.


Challenges: We gained critique on how our initial design solution overlooked how student’s struggle in maintaining charge could be due to poor device charge management. A crucial mistake in developing a solution based on the assumption that student’s lack of battery life was due to the physical technology rather than their overconsumption of device use. Reevaluating on our original rentable portable battery solution and taking constructive feedback from peers, reviewers, and potentially stakeholders is an essential part of the design process.


Reflection: This was my first end-to-end design project from ideation, research to design. The biggest takeaway was how valuable user feedback and design critique is to iteration between low to high fidelity. As a designer, I learned how my decisions directly effect user experiences which is why every design choice must be purposeful.
