1. Why?
• Our system offers a wide range of location-based learning mis-sions
• Lead user to generate diverse activities based on their interest
and context
2. Missions
System-generated missions
• Location-specific missions
e.g. Post about “acceleration of gravity” when you visit the Seoul National
Science Museum
• Theme-specific missions
e.g. Take a photo of differently shaped & colored fallen leaves
User-generated missions
• Expect personalized play experiences
• Promote social engagement.
Let’s Solve Mission To help users to learn about diverse themes in their surroundings through out-
door activities

Several Issues in current posting and commenting interfaces in So-cial Network Services (SNS)
1. Why?
• Not effectively support collaborative discussion about postings with photo
• Not efficiently facilitate learning from crowdsourced comments on the
postings
2. A new post-comment interface
Pin-based annotation system
• Marking a pin on a photo when posting to specify posting intention
• Locating a pin to elaborate discussion about a photo with comments
Functionality
• Posting: Descriptions/ Tags/ Pin
• Commenting:
- Sequence of comments: Brightness of pins
- Topic of discussion: Frequency and distribution of pins
- Conclusion of discussion: Comments with many ‘like’

1. Gamification (Top-down vs. Bottom-up)Appendix. 1
To engage users, we have employed not only top-down but also bottom-up gamification mechanisms in our application design.
Top-down mechanism : refers to pre-defined reward-based gamification strategies often called BLAP (Badges, Levels & Leaderboards, Achievements, and Points).
Bottom-up mechanism : means gamification strategies promoting users’ in-trinsic motivation by providing personalized play ex-periences and social engagement.
Specially, we have focused on User-Generated Mis-sions (UGM) to promote users’ intrinsic motivation and participation by means of bottom-up gamifica-tion approaches.
