2010 “ The Map Trap ”

The Map Trap
“ ”Goal analyze the impact that the type of user interface has on the
search and information discovery experience of mobile users
“Motivation The interface design of . . . mobile Web services may be organized in two distinct groups [ in terms of how they ] display information:
”. . . to date, little light has been shed on the implications that these mobile interface modalities have on the experience of their users
the place to which it refers (e.g. geographical)1order or ranking (e.g. time or search engine ranking)2
![Page 16: Mobile HCI IS 698/800](https://reader035.vdocument.in/reader035/viewer/2022062310/56816976550346895de15ff2/html5/thumbnails/16.jpg)
The Map Trap : SSB
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
Social Search Browser
search, answer, ask questions socially
browse geo-tagged queries in two modes

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

Questions
Q 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 Any other questions?

Orientation vs. NavigationOrientation
Understanding of one’s locationDirection of nearby destinations

Why Indoor Navigation Is HardNeed 2 points to orient yourself
Permanent landmarks are rarely found insideCan lose you orientation when changing
buildings and floorsHow many times did the stairs turn?
Low visibility of destinationsIndoor destinations are not big and they tend
to look alikeAttention diverting stimuli
Shiny things & interesting people are plentiful
![Page 25: Mobile HCI IS 698/800](https://reader035.vdocument.in/reader035/viewer/2022062310/56816976550346895de15ff2/html5/thumbnails/25.jpg)
The StudyAim 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, France14 participants
9M/5F, varied in nationality, professions and agesUsing an app developed specifically for the
air show by Insiteo on Android SmartphoneTechnical difficulties:
Jumpiness, temporarily inaccurate positions, temporary disappearance
Question:What do we think of the study setup?
![Page 26: Mobile HCI IS 698/800](https://reader035.vdocument.in/reader035/viewer/2022062310/56816976550346895de15ff2/html5/thumbnails/26.jpg)
The Tasks1. Find a stand in the same hall
a) Find it on the appb) Point to it from current positionc) Navigate to stand
2. Find and meet another persona) Use MeetMe feature of the appb) Find person & mark location on paper map
3. Find a stand in another halla) Find the stand on the appb) Point to itc) Mark it on the paper map
![Page 27: Mobile HCI IS 698/800](https://reader035.vdocument.in/reader035/viewer/2022062310/56816976550346895de15ff2/html5/thumbnails/27.jpg)
Quantitative ResultsWide range of performance
Both in duration and accuracy of the taskOnly low to medium mean accuracy
![Page 28: Mobile HCI IS 698/800](https://reader035.vdocument.in/reader035/viewer/2022062310/56816976550346895de15ff2/html5/thumbnails/28.jpg)

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?
![Page 30: Mobile HCI IS 698/800](https://reader035.vdocument.in/reader035/viewer/2022062310/56816976550346895de15ff2/html5/thumbnails/30.jpg)
Two Strategies EmployedContinuously looking at the phone only
Turning too late or too soonWrong turns (180 degree disorientation)Nearly or actually bumping into peopleNot spotting destination until reaching it
Looking at both the phone and environmentLess likely to experience above problemsGot to their goal faster
Question:If looking at environment is obviously better, why do so many people stare at their phones?
![Page 31: Mobile HCI IS 698/800](https://reader035.vdocument.in/reader035/viewer/2022062310/56816976550346895de15ff2/html5/thumbnails/31.jpg)
Blindly following Navigation

ConclusionsPersonal navigation strategies differDestinations will be achieved eventually,
but better orientating is neededTasks of Orienting and Navigating need to
be separatedInattentional blindness occurs often, need
to look away from the screenAudio or Haptic solutions?
Decreased awareness of surroundings causes mistakes in navigating and potential for collisions
Question:Are these conclusions the same for mobile and paper maps?

Location sharing• Is really hard
• Varies based on who is asking, current activity
From Consolvo et al., 2005
