15. The Map Trap “ analyze the impact that the type of user interface has on the search and information discovery experience of mobile users Goal ” “ Motivation The interface design of . . . mobile Web services may be organized in two distinct groups [in terms of how they ] display information: the place to which it refers (e.g. geographical) 1 order or ranking (e.g. time or search engine ranking) 2 . . . to date, little light has been shed on the implications that these mobile interface modalities have on the experience of their users ”

16. The Map Trap : SSB Social Search Browser search, answer, ask questions socially browse geo-tagged queries in two modes TEXT MAP Proactive map based interface displaying all queries executed by all users in a given physical location Connects to a user’s social network so that friends can help each other by answering each other’s queries while on-the-move

18. The Map Trap : Results TEXT MAP QUERIES 92 144 LOOKUPS 594 291 ANSWERS 123 72

19. The Map Trap : Key Points 1 Choice of user interface depends on: personal preferences situational context information need 2 Design implications: auto-learn user interface preferences auto-learn situational context auto-learn user intent P.S. support fuzzy / vague location matching = Win! “ 3 Text vs Maps: Participants consistently preferred [ text ] when they were consuming information . . . This preference was less pronounced when they were seeking information. ”

20. Questions How might have a more balanced gender representation affected the results of the study? Q If user preferences stem from experience, are we doomed to make merely iterative improvements? Q What implications does “text for consuming, maps for seeking” have on design? Q Q Any other questions?

21. Lost in Navigation:Evaluating a Mobile Map App for a Fair IS 698 Presented by: Marie K. Silverstrim

22. Intelligent Systems Lab Amsterdam (ISLA), Univ. of Amsterdam Dr. Anders Bouwer PhD in CS 2005 Dr. Frank Nack PhD Lancaster Univ., UK Abdo Abdallah El Ali 4th yr PhD in Mobile HCI • Research Interests: • Music computing • Intelligent multimedia • & multimodal interfaces • Intelligent navigation • AI & Human • Intelligence in general • Research Interests: • Context & process aware • media knowledge spaces • Representation & • adaptation of experiences • in mobile environments • AI and films • Research Interests: • Usability & UX • Multimodal Interaction • Gesture-based • Interaction • Ubiquitous Computing • Playful HCI

23. Orientation vs. Navigation • Orientation • Understanding of one’s location • Direction of nearby destinations • Navigation • The process of moving to that destination $ $ $

24. Why Indoor Navigation Is Hard • Need 2 points to orient yourself • Permanent landmarks are rarely found inside • Can lose you orientation when changing buildings and floors • How many times did the stairs turn? • Low visibility of destinations • Indoor destinations are not big and they tend to look alike • Attention diverting stimuli • Shiny things & interesting people are plentiful

25. The Study Question: What do we think of the study setup? • Aim of study: • How well users can navigate and orient themselves with mobile app at an indoor fair • Setup of study: • Paris Air Show at Le Bourget Airport, France • 14 participants • 9M/5F, varied in nationality, professions and ages • Using an app developed specifically for the air show by Insiteo on Android Smartphone • Technical difficulties: • Jumpiness, temporarily inaccurate positions, temporary disappearance

26. The Tasks • Find a stand in the same hall • Find it on the app • Point to it from current position • Navigate to stand • Find and meet another person • Use MeetMe feature of the app • Find person & mark location on paper map • Find a stand in another hall • Find the stand on the app • Point to it • Mark it on the paper map

27. Quantitative Results • Wide range of performance • Both in duration and accuracy of the task • Only low to medium mean accuracy

28. Qualitative Results • Good general impression • Good to very good useful • Easy difficulty of tasks • Easy to very easy user interface

29. Disconnect in Results “Although all participants were afterwards generally positive about the system and the study, 6 of them seemed very insecure while performing the tasks.” p.178 Quantitative says the tasks were difficult… BUT! Qualitative says the tasks were easy…? Question: Why the disconnect?

30. Two Strategies Employed • Continuously looking at the phone only • Turning too late or too soon • Wrong turns (180 degree disorientation) • Nearly or actually bumping into people • Not spotting destination until reaching it • Looking at both the phone and environment • Less likely to experience above problems • Got to their goal faster Question: If looking at environment is obviously better, why do so many people stare at their phones?

31. Blindly following Navigation http://www.youtube.com/watch?v=a2QIH2uz3p8

32. Question: Are these conclusions the same for mobile and paper maps? Conclusions • Personal navigation strategies differ • Destinations will be achieved eventually, but better orientating is needed • Tasks of Orienting and Navigating need to be separated • Inattentional blindness occurs often, need to look away from the screen • Audio or Haptic solutions? • Decreased awareness of surroundings causes mistakes in navigating and potential for collisions
