Intro to HCI, January 9, 2014
The following documents steps of the design process as explored in my Intro to HCI class. For this assignment, students were tasked with the challenge of redesigning the experience of waiting in line, and illustrated their results through the process of: observation, brainstorming, synthesizing, prototyping, and testing.
- Brainstorming - List of 20 Redesigns for Improving the Experience of Waiting in Line
1. Airport Security Line (Avoid long lines): Use electronic keycards/tags to keep track and quickly clear items through security checks at the airport
2. Airport Baggage Line (Relief): GPS Tracking for luggage that allows users to stay aware of where their baggage is
3. Restaurant seating line (Entertainment): Buzzer with a game installed on it (Tetris for kids, and poker for adults) that freezes when the buzzer is outside of a certain range & when the buzzer is beeped.
4. ER waiting line (Relief): GPS Tracking for the doctor to let the patients know where the doctor is and his activities
5. ER waiting line (Relief): Screen that announces the estimated wait time
6. DMV line (Productivity): Machine that performs the simple services a user needs to decrease the wait time.
7. DMV line (Entertainment): Mobile game that gives people in line a chance to “cut to the front”.
8. DMV line (Entertainment): Animal cam that people pay money to watch, like a parking meter
9. DMV line (Entertainment/Charity): Have interactive applications behind chairs that will profit government/non-profit charities
10. Café/Coffee Shop line (Entertainment/Charity): Have charity/unique/research/local art display on tablet in checkpoints in the line
11. Café/Coffee Shop line (Entertainment): Photo station inline (with green screen to change wallpapers), pictures posted on wall and updates frequently
12. Café/Coffee Shop line (Productivity): Have yelp application available in line to compare items in menu and ratings online in real time
13. Café/Coffee Shop line (Productivity/Social): App where stamps will be rewarded if the user interacts with another user using the same application that promotes the shop as well as entertains the user.
14. Café/Coffee Shop line (Entertainment/Social): Allow users to write notes that will be hung on the wall/display in the shop (much like a Christmas tree ornament)
15. Café/Coffee Shop line (Entertainment): Chalkboard walls so users can draw (there will be a base image that will be frequently changed so that each user can add on to the theme as they wish)
16. Café/Coffee Shop line (Entertainment): Picture cutouts of the store icons/trendy characters for users to take pictures in
17. Café/Coffee Shop line (Entertainment): Treasure hunt on the walls of line, find hidden objects (like waldo all over the wall)
18. ATM line (Productivity): Add-on to the current mobile banking that allows users to send their needed service to the app, and immediately initiates with a swipe of their ATM card
19. ATM line (Relief): Add tent or covering that provides shelter during bad weather (for outside ATMs only)
20. Parking lot line (Avoid long lines/Productivity): Users given X amount of time to choose available parking spot through touchscreen otherwise spot will be randomly chosen
21. Café/Coffee Shop line (Productivity/Entertainment): Users play a game to win coupons/discounts for their purchases
22. Cafe/Coffee Shop line (Entertainment): A live camera feed allows users to decorate their own images in different styles and accessories
Idea 1: A mobile bubble shooter game app that allows users to win discount coupons for their purchases
How: By drawing out the design of the app on app-sized sheets of paper
Why: I chose this prototype because I believe that this mobile game app both entertains the user (taking away their boredom in waiting) and allows them to turn this experience into something rewarding and productive (winning a discount for whatever they’re in line to purchase).
Idea 2: A camera app that allows users to customize their look with various different accessories and styles
How: Drawn rough sketch of customized looks and what the general screen would like on paper
Why: I chose this prototype because I think this kind of customization app allows the user to stay entertained (by making funny looks and playing with the different accessories) for a short period of time, ensuring that they can move forward with the line easily.
- Testing - Observation and recording of users trying the prototype
Idea 1 User Testing: @ Tapioca Express (a local tea place) with 2 users
- User Insights
Idea 1 Insights:
- People commented that the idea was cute and clever, especially if this mobile game was used in conjunction with Tapioca Express, because the bubbles in the game reflects the theme of the store.
- Users liked that there was a coupon rewarded after the game was finished because it gives them incentive to play.
- A few users reported that they preferred another game to play instead of the bubble shooter game (Candy Crush), saying it could be more challenging (I chose the bubble shooter game because I thought it was suitable for children and adults).
- One user noted that the home screen of the app is confusing because it doesn’t state that it’s a game, only that something is about to begin, which I agreed is a layout and wording issue.
- Most users were confused on the ad bar on the bottom, and when told about the ads, didn’t want ads in the game. This could be something to remove or incorporate into the app design in a more natural way, such as putting the store logo in the bubbles.
- I noticed that the app is time-intensive during a line: users would not finish the game and already reach the cash register. A possible solution could be to give the game a time limit?
- Another user mentioned if the ads were promoting sale items in the store. It could be an add-on feature to allow users to see items from the menu in the game, etc.
- Another issue of the game is the number of times the game can be played. I think it could be limited to once a day, and the coupon/discount could change daily or weekly.
- Also noticed that some users were unsure of how the game/coupon app worked. A tutorial could be helpful in guiding users on how the system works.
