  1. Ultimate Goals of Wiisard • Improve the efficiency of response • Increase victim flow through key areas • Reduce bottlenecks • Reduce cost of errors • Improve the efficacy of response • Reduce numbers of errors • Improve situation awareness Mid-Tier • Data Collection • Interviews • on site • off site with hand simulation • Shadowing key responders taking photos and notes • Counting victim flows at key nodes • Logs • Usability • on site with responders • on site, with responders after activity • in lab • Video, ethnographic study • Complexity of routines: Ri is better than Rj if Ri tasks: • - are more complex • - can be performed in acceptable time and error rate • Triage: PDA vs. paper • - can do more complex routines in acceptable time • Transport: Mid Tier vs. paper • - can do more complex routines in acceptable time Patient Monitor • Recovery time of Routines: time to recover previous level of routine performance after interruption, disruption, switch of activity. • Design Challenge: • redesign the environment to lower recovery time • redesign to facilitate vigilance and error detection Provider Device Intelligent Triage Tag Evaluate information diffusion through computer simulations Information diffusion: how quickly and accurately information is propagated through a communication network When does increased information diffusion compensate for the time responders lose to communicating rather than responding? Assumptions: nature of links, responder locations, number of agents • Cost-benefit structure of a Disaster Response System (DRS) along many dimensions. Static world In a world where things change very slowly Wiisard provides a large initial advantage in information diffusion. However regular channels do catch up and slightly exceed Wiisard. Changing World Bad Connectivity In a dynamic world where victims change state a communication channels which Wiisard provide will dominate, although there remain potential dangers of local inconsistency. Changing World Good Connectivity In a dynamic world where Wiisard network has frequent problems users are no better off with it than without it. Evaluating Disaster ResponseThe Wiisard Project David Kirsh Dept of Cognitive Science, Cal(IT)2UCSD • What is WIISARD? • Wireless Internet Information System for Medical Response to Disasters • Disaster responders operate under a standardized Incident Command System. • Old Artifacts: all record keeping is done by hand using pencil and papers, and communication channels are radio and runners in addition to sound, sight and touch. • New artifacts introduced by WIISARD: • Provider Device: a hand-held device that records START triage, patient details, interventions, vital signs, barcode scanner for patient identification. • Intelligent Triage Tag (iTAG): for rapid triage and registering of patient into the system via wireless. • Individual Patient Monitors: for wireless transmission of pulse oximetry and telemetry data. • Mid-Tier: tablet pc with applications specific to the roles of Triage, Treatment, Transport and Staging. • Conceptualization of disasters • To understand how response units conceptualize the physical space of a disaster and their organized response in order to develop an ontology for geospatial and context-aware technology. • Quantitative Objectives • Victim Flow Rate per node Table 1. Geolocation attributes of space types: the conceptual map of first responders is far more complex than a geographical map. Information diffusion: Wiisardvs. standard system
