For the class UX Prototyping.

1. Guess Who?
Kyung Jin Hong
Kangeun Lee

2. Guess Who?
• Cell phone application
• GPS-based
• Target: YIC students
• Purpose: Meet new friends in college

3. Design Concept
• What: Find friends with similar interests
• Who: Students who live at YIC dorm
• Where: Songdo
Dormitory  Haekyung  Dongchun  Parks

4. Design Concept
• How
1. Find students with common interests through surveys
2. Pair students up with same interests
3. Mission: Give place-based theme (ex: daily life) and make each
person take photos, sound files or other contents at different
places and send them to each other. The goal is to find out
who the other student is.
4. Repeat process in teams

5. Design Concept
• Why
• Hard to make friends in college
• Hard to find people with similar interests
• Give chance to meet people you might not get to meet normally

6. Functions
• GPS-based Hints
• Receive half of photo from partner
• Guess what place it is and go there
• Follow map with only user’s location
• User can ask for hints from map (Ex: Go west 50 meters)
• When they arrive at place GPS triggers second half of photo to be
sent

7. Functions
• Reward System
• Player who finds out partner’s movement pattern first gets info
about partner
• Player who gathers all the info about their partner and finds out
who the person is gets reward (Ex: movie tickets)
• Use reward to get closer to partner

8. Scenario
• Persona 1: 유재상
• Freshman, RC student
• Hobbies: Watching movies, finding 맛집, drinking
• Stays at dormitory during weekends
• Persona 2: 정예인
• Sophomore, Non RC
• Hobbies: Watching movies, finding 맛집, taking photos
• Usually stays at dormitory during weekends (sometimes goes home)

9. Scenario
• Jaesang sees a recommendation for app on school bulletin. He
downloads the app on his phone.
• He fills out the survey with his interests and other basic
information.
• He is matched to a partner through the app. The game starts.
• He gets the first week’s mission, which is to send his partner
photos of places he goes to in YIC.
• He takes a photo of his lunch at 라온샘 and sends it to his
partner.
• He receives a photo of a place from his partner, but it is cut in
half. The app tells him to find the place in the photo to see the
other half.

10. Scenario
• He guesses that the photo was taken at 언기도 트레비
앙. He goes there and is sent the other half of the
photo through GPS. Because he found the first place
faster than his partner, he gets one point.
• He and his partner exchanges photos through the week.
At the end of the week, Jaesang has more points than
his partner, so he receives a hint about who his partner
is.
• The game continues for three more weeks, and Jaesang
finds out first who his partner is through all the hints.
He wins the game and receives movie tickets that he
can enjoy with his partner Yein
