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)1

order or ranking (e.g. time or search engine ranking)2

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

3Participants 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

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

NavigationThe process of moving to that destination

$

$

$

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

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?

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

Quantitative ResultsWide range of performance

Both in duration and accuracy of the taskOnly low to medium mean accuracy

Qualitative ResultsGood general

impressionGood to very good

usefulEasy difficulty of

tasksEasy to very easy

user interface

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?

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?

Blindly following Navigation

http://www.youtube.com/watch?v=a2QIH2uz3p8

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?

Let’s take a break

Next up: A1 Q&A, Location activity

37

App presentations

• I’d like to see:– Google Project Glass– Swype or SwiftKey

38

Assignment 1 Q&A

• Status check-in– How is everybody doing?– Who needs help?– Who wants feedback?

39

Design challenge

• Groups of 3 (or 2): pair up with someone you don’t know

• We’re going to sketch some location aware interfaces

40

Location sharing

• Is really hard

• Varies based on who is asking, current activity

From Consolvo et al., 2005

41

Example location sharing services

• Foursquare:http://www.youtube.com/watch?v=N6bRRjY52t4

• Google Latitude: http://www.youtube.com/watch?v=Q-Oq-9enE-k

• Amber Alert GPS: http://www.youtube.com/watch?feature=player_embedded&v=liZJf2o8RHw#

• Life360: http://www.life360.com/tour/

42

Group activity

• Sketch out the map view of a location tracking app for parents and kids

• Parent view and kid view

• Should support helicopter and non-helicopter parents

• Step 1: Design the parent view

• We’ll present them to the class in 10 minutes

43

Activity Part 2

• Design the kid view– What the kid would tolerate

44

Upcoming

• Next week: Search and information seeking
