  1. A Comparative UI Study for MyPlace Mobile Navigation in Ubiquitous Environments – Comparing Affect and Effectiveness of Linguistic and Cartographic Communication Carolin Plate University of Osnabrueck Cognitive Science Programme

  2. Philosophy of Cognition Cognitive Psychology Computational Linguistics Knowledge-based Robotics Neurobio- psychology Artificial Intelligence Neuro- informatics Theoretical Computer Science Study Background Cognitive Science at University of Osnabrück • Bachelor’s • (Oct 02 – Nov 05) • Linköpings Universitet • Thesis at DFKI in the field of Usability Engineering • Master’s • (Oct 05 - current) • Thesis at University of Sydney 1) 1) Image taken from: www.cogsci.uos.de

  3. 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) 2) dual-coding hypothesis (Pavio) 2) Image taken from: http://www.brainwave-entrainment.com/brain-hemispheres.jpg

  4. Spatial Cognition – are we all different? • Gender Differences • Visualizers + Verbalizers • Do we (all) form cognitive maps? (C) www.CartoonStock.com

  5. 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… 3) 3) Image taken from: http://db.auth.usyd.edu.au/directories/map/building.stm?location=25L

  8. 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 Devices

  9. Interface Design Graphical UI Text-based UI Devices View 1: Object- based Overview

  10. Scenario and Tasks You just joined the CHAI group for doing your Honour‘s year. On your first day, you are called to an appointment with Prof. Judy Kay to plan your research. • Go to… • 1) • … • 4) • Give Directions to … • Go to… • 1) • … • 4) • Give Directions to … Questionnaire Text Interface Map Interface

  11. Data Collection for Hypothesis You just joined the CHAI group for doing your Honour‘s year.

  15. People Hidden device Device Task-related room Landmark Possibilities for Tasks Level 4 M: Hidden fridge and microwave M: consult rooms Level 3 W: Thai Fridge W: printer W: Judy’s office W: Wii and sofas Level 2 E: consult room E: Ugrads officer E: reception, mail E: copier, scanner W: Usability Lab Level 1 E: kitchen with coffee E: lecture theatre E: board room (PC) W: hidden showers W: Master’s workstations W: digital projector

  16. 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
