2 Differences in Evacuation Responses from Word Choice Bryan L. Hoskins, Ph.D. Oklahoma State University
3 Outline Introduction Study Design Variables Results Discussion
4 Introduction Voice systems Effective at communicating message Becoming more prevalent Messages need to be developed Smart buildings
5 Introduction NIST study Important types of information to give How people process information In Annex of NFPA72
6 Study Design Participants All college students in major Two different routes for each 43 individuals 14 groups (34 individuals)
7 Study Design Location Student Union Floor that they were typically unfamiliar with Instructed on route to take to arrive Many other people present
8 Study Design Instructions Fire in the building (specific location) Told to only take designated route Directions different based on variables Four steps to remember
9 Variables Familiar vs. unfamiliar Native language Single vs. repeated vs. half at a time Landmarks vs. compass vs. turn direction
10 Results Individuals All participants able to finish both routes 39 (45 %) wrong routes Comparisons with t-tests
11 Results Order of scenarios 22 had familiar route first 21 had unfamiliar route first No apparent effects based on which route was first
12 Results Native language 30 English as native language 13 English not native language No apparent effects based on native language in total mistakes
13 Results Instructions 15 had instructions only given at start 14 had half of instructions at start, half at midpoint 14 had repetition of message at midpoint
14 Results Instructions Instructions at start significantly worse, especially for unfamiliar route Repeated instructions about average Divided messages had best results
15 Results Type of directions 15 had turn notation (e.g. left or right) 14 had landmarks 14 had compass directions
16 Results Type of directions Compass directions were by far the worse Qualitative differences between landmarks and turns
17 Results Groups All groups able to finish both routes 13 (46 %) wrong routes 3 (10 %) had group correct Similar trends to individuals
18 Discussion Less is more Use guidance that is familiar to people Anything that involves a compass direction (south stair) is problematic Groups will communicate

54 Wearable Eye-Tracking Human Perception of Exit Signs During Building Evacuation Robert Till John Jay College of Criminal Justice New York, NY USA Dominick DeRubbio Agile Risk Group New York, NY USA
55 Overview - Demonstrate wearable eye-tracking technology as a tool to study pedestrian and evacuation dynamics Examine the visual behavior of individuals, both familiar and unfamiliar with a space, navigating toward an exit Use event-based coding analysis to summarize behaviors
56 Exit Behavior It is a generally accepted principle in fire protection that in an emergency most people will first attempt to leave a building the same way they entered. [McClintock et al., 2000]
57 Sometimes People Can t Mass transit stations passengers may be forced to disembark at unfamiliar locations High-rise buildings elevators are used as the primary means of entry, but stairs must be used in an emergency
58 Sometimes People Can t Airports Disembarking at an unfamiliar location, finding baggage, already checked through security. Exit Obstructions Areas where a person first gains entry to a facility may not be available.
59 Questions How do pedestrians behave when searching for the nearest exit under these conditions? Do they look at, and follow, signs? Do they take cues from others? Use some unknown navigation method? Perhaps a combination of these?
60 Why study eye movements? Conclusions from the body of research show that where people fixate (look) is closely linked to the attentional demands of the task and that wearable eye-tracking is a good tool for monitoring the sequential thought process.
61 Gaze During Natural Behavior Walking through a cluttered room [Franchak et al., 2009] Driving a car [Land and Lee, 1994] Making tea [Land et al., 1999] Washing hands [Pelz and Canosa, 2001] Playing table tennis [Land and Furneaux, 1997] Playing cricket [Land and McLeod, 2000]
62 Recording Behavior Fahy identified exit choice decisions, which determine travel paths and affect travel times as a type of data needed for evacuation models that we currently lack.
63 Recording Behavior She also stated videotaped observations of actual evacuations are ideal, since they show exactly what people did, and the elapsed time can be calculated directly from the tape.
64 Wearable eye tracking achieves Fahy s goals without obstructing the travel route of the wearer and with minimal influence on the wearer.
65 Study Goals 1. Determine if humans actually use exit signage.
66 Study Goals 2. Identify if there is a difference in the use of exit signs between those who were familiar and those who were unfamiliar with a building environment.

69 Software to Weave The Views Together
70 Experts Worked in building or claimed to be familiar. Novices - Never visited the building before. Most walked from Start (room 3531) To Stair Exit B (Public Administration Dept.)
71 Environment - Floor
72 Data 2010 study 10 Subjects Later Study - 41 subjects tested/data from 40 used.
73 2010 Results suggested that novices used exit signs and experts did not.
74 Subject Evacuation Instructions Your goal is to locate a doorway that will take you outside of the building - i.e. you should be able to see daylight or a marked way out of the building - and take a picture of that location for documentation. Do not actually leave the building, and avoid passing through any turnstile, as this will require us to recheck you in through the security desk
75 Evacuation Instructions (2) Also, do not make use of any elevators. Remember, your goal is to simply "find" a way out of the building and document it. Once you have taken the picture, return to this office and the test will be complete
76 Experts Worked in building or claimed to be familiar.
77 Novices - Never visited the building before
78 Experts Worked in building or claimed to be familiar
79 Novices - Never visited the building before
80 Video - Expert
81 Video - Novice
82 Study Goals 1. Determine if humans actually use exit signage.
83 A total of 26 occupants or 65% of subjects tested utilized exit signs while identifying a way to the street. Clearly, some people use exit signs, novice or expert, judging from this small sample size.
84 Findings The average number of gazes at an exit sign per subject was 6.6.
85 Study Goal (2) Identify if there is a difference in the use of exit signs between those who were familiar and unfamiliar with the building environment.
86 Findings (61%) of the novices and (68%) of the experts gazed at exit signs while navigating the building.
87 Findings Novices recorded a total of 115 gazes at exit signs and experts recorded a total of 103 gazes.
88 Challenges and Conclusions Were the experts really expert? The outcome of the original experiment suggested that expert subjects didn t use exit signs they knew where to go. In later cases, experts did view the exit signs. It is possible that we had people self-identify as experts that were not?
89 Future Studies Increase sample size Work to better identify true experts and novices
90 Future Studies Create a more realistic experience (horns/strobes) Flashing versus non-flashing signs, height, color
