Usability Study of SmallWorld: Understanding User Interactions with Location-Based Social Software

This overview presents the findings from a usability study of SmallWorld, a location-based social software that faces unique design challenges. The study involved 7 participants aged 16-27, focusing on their perceptions of friends, location, mobile devices, and privacy. Three tasks of escalating difficulty were performed, revealing insights into user behavior and interface issues. Results indicated areas for improvement, such as redundant controls, better visibility options, and the need for enhanced privacy features. The study emphasizes the importance of user feedback in refining design.

  2. Usability Study • Product & Experiment Overview • Method • Demo of • Tasks • Study Results • Additional Design Recommendations • Summary

  3. Experiment

  4. SmallWorld • Location-based social software: a new paradigm • Presents unique design challenges How do users think about their: • Friends • Location • Mobile Device • Privacy ! • A usability study as a means of discovery

  5. Method

  6. Method • 7 users • 16 – 27 years old • 3 Female • Varied backgrounds • 3 tasks • Scripted to standardize experience

  7. Method • 1:1 • More participants • Natural environment • Follow-up dialogs • Great data!

  8. Tasks

  9. Tasks • 3 tasks • Escalating difficulty • Non-leading words *demo*

  10. Task 1 Find the nearest friend and call them to see if they can have lunch with you. (easy)

  11. Task 1 Results Not too serious Simple fixes 1/7 “Too small to click!” “What does this dot mean? Is it me?” 2/7

  16. Task 3 Results “The plus button isn’t obvious” 3/7 “Too awkward to resize” 3/7 4/7 “What does a Group Zone do, anyway”

  17. Design Recommendations

  18. Add Redundant Controls

  19. Design Recommendations • Hiding from all friends (invisibility mode) • Temporarily hiding from groups • New concepts: • “granularity of visibility” • Other privacy features • ?? • More testing!

  20. Summary • What is SmallWorld? • Usability study • New design challenges • User feedback • Minute  restructuring
