Do we Think in Pictures? (sometimes?)
Human information processing– Human memory
• different for auditory and visual signals
– Hemispheres• local (L) + global (R) information
Theories in information representation• Propositional representations (Pylyshyn)
• Visual images (Shephard)
• Mental models (Johnson-Laird) cognitive maps (Oatley)
dual-coding hypothesis (Pavio)

Spatial Cognition – are we all different?
• Gender Differences
• Visualizers + Verbalizers
• Do we (all) form cognitive maps?

Research Question
Mobile Navigation in Ubiquitous Environments – Comparing Affect and Effectiveness of Cartographic and Linguistic Communication
• Mobile Navigation– Pedestrians indoor, equipped with PDA
• Ubiquitous Environment– “invisibility problem”
• Affect + Effectiveness– Usable: effective, efficient, fun to use in the special context (ISO 9241-11)
• Communication– HCI
Text is linear and flexible…

What I gonna add…
• Models– More devices
• Wayfinding: display paths
• Display landmarks + devices– Show / Hide in map
• Show map– Zoom in current location– Zoom out (one level)– View class of objects

Current Tasks
Start: Level 1: Foyer• 1w: 15 min too early. Is there sb around to have a chat?• 3: Meeting with Judy. Go to her office.• 3: Lunch. Find microwave to warm up food.• 2w: future lab: group meeting starts in 5 min, where is it? give directions to the exit you entered the building.
• 1e: meet the group for coffee at 10.00• 1w: You need to give presentation in the Lecture Theatre tomorrow and use
slides for it. Make sure you have all the equipment you need.• 2e: Copy something / consult ugrad officer• 4e: meet Prof. Miller at consult room give directions to Future Lab Go to consult room? to fill in questionnaire + debriefing

Attributes of Texts and MapsTextual Descriptions Maps
Sequential + linear (Shneiderman 96, Freksa 99)
Multiple 2D-layers (Shneiderman 96, Freksa 99)
allows for mirroring the linear nature of following directions: temporal or logical sequence (Denis)
allows for indexing by location, superseding labeling (LarkinS 87)
more active search, comprehension and inferences required (Cox99)
search along these groupings is facilitated (LarkinS 87)
Unconstrained form of representation Bound to the spatial relations they mirror
Powerful enough to describe arbitrary concrete or abstract relationships (Freksa 99 + KrayELC)
maps facilitate certain abstractions and inferences (LarkinS 87), aids processibility thereby, but are only suitable for a certain class of information (StenningO 92)
we can remain unspecific about details, errors are less likely to occur (Denis)
spatial representations can be derived directly so a mapping to the real world is facilitated (Freksa 99)
Just landmarks on the way are described Provide context by depicting environment
descriptions can be highly personalized and targeted to one specific task (Freska 99)
time for a first orientation in the map is needed before the route to be followed is identified (Freska 99)
as a side effect, distraction by unnecessary information is minimized (Freksa 99)
in the case of getting lost, alternative routes can be found (Nagi 06)
orientation and learning is facilitated (Nagi 06, Freksa 99)
