Wednesday, 24 June rd UKIBNET Workshop1 Distributing Cognition in the design of ubiquitous computers Chris Baber Pervasive Computing Group The University of Birmingham
Wednesday, 24 June rd UKIBNET Workshop2 The Design Challenge UbiComp assumes highly interconnected network of disparate systems but there is no architecture UbiComp assumes invisible interfaces to users but users can’t manage want they can’t see UbiComp assumes adaptation to context, but it is not obvious which features are appropriate
Wednesday, 24 June rd UKIBNET Workshop3 System Layers Socio-technical interaction Human/computer Interaction Application Programming Cognition & Perception Assembly Language Operating Systems Machine Language Posture & Movement Digital Logic Physical Feedback Physical Inputs Information & knowledge Activity & Culture Convention
Wednesday, 24 June rd UKIBNET Workshop4 A Tangent… Distributed Cognition addresses the interactions between people and everyday objects to explore the relationships between the actions people perform and the environment in which they live and work
Wednesday, 24 June rd UKIBNET Workshop5 Distributed Cognition Exploring the ways in which objects in the world support human actions [HUTCHINS] Resources for Action [SUCHMAN] –Objects in the Environment –Procedures and sequences of action
Wednesday, 24 June rd UKIBNET Workshop6 What is being distributed? System-level view of cognitive Processes [PERRY] Input –Sensing relevant factors Processing –Interpreting current context Output –Determining appropriate response Provision of information Action of person
Wednesday, 24 June rd UKIBNET Workshop7 From theory to (design) practice Resources for Action [WRIGHT ET AL.] –Objects-in-the-World… Represent… –Abstract Information Structures… –Action on Objects changes their states
Wednesday, 24 June rd UKIBNET Workshop8 Context & Resources Goal Plan Action History State Outcome Posture & Movement Location Object / People Time
Wednesday, 24 June rd UKIBNET Workshop9 Simple Mappings GOAL indicated by: –Location –Adjacent Objects –Time (relative to schedule / diary) –Available information
Wednesday, 24 June rd UKIBNET Workshop10 Information and Movement
Wednesday, 24 June rd UKIBNET Workshop11 Annotation through action Capture image Rectify image Mark image –Drawing –Data from sensors
Wednesday, 24 June rd UKIBNET Workshop12 Collaboration through activity Search of site… detected and passed to Control where it is… displayed on screen… and directions sent back
Wednesday, 24 June rd UKIBNET Workshop13 Conclusions Wearable Computers provide a channel through which humans can act upon the world and the objects it contains in order to interact with real and virtual information In this way, cognition can be distributed across people and the (increasingly) smart environments in which they work and play
