Introduction • Introduction • App-Design • Survey • Discussions • Ozone is formed in the air through a complex series of reactions involving light and chemical precursors. • High levels of ozone are harmful to health and the result of pollution under certain environmental conditions. • The American Lung Association currently ranks Houston #7 among most ozone-polluted cities.
Introduction • App-Design • Survey • Discussions • Until recently only a categorical qualitative description was possible for metropolitan areas. • With the proliferation of environmental sensor networks, real-time quantitative and localized ozone information has become available. • OzoneMap app: Evolution of ‘ozone clouds’ in the Houston area for the past two hours. • Visualization conundrum for designers and users.
App Design • Introduction • App-Design • Survey • Discussions
Survey of Potential Users • Introduction • App-Design • Survey • Discussions • A total of 51 participants (31 males and 20 females) volunteered for this user study. • The participants were asked to view two videos and then answer a set of questions. • Q1: Rate the temperature style representation of the evolving ozone data. • 1= Poor ; 2= Fair ; 3= Good ; 4= Very Good ; 5= Excellent • Q2: Rate the radar style representation of the evolving ozone data. • 1= Poor ; 2= Fair ; 3= Good ; 4= Very Good ; 5= Excellent • Q3:Do you consult weather predictions over your smartphone and/or the Internet? • 1= Never ; 2= Rarely ; 3= Sometimes ; 4= Often ; 5= Very Often • Q4: Do you consult pollutant predictions over your smartphone and/or the Internet? • 1= Never ; 2= Rarely ; 3= Sometimes ; 4= Often ; 5= Very Often • Q5: Do you walk or run outdoors in a metropolitan area? • 1= Never ; 2= Rarely ; 3= Sometimes ; 4= Often ; 5= Very Often • Q6: Gender / Q7: Age / Q8: Education Level
Survey Analysis • Introduction • App-Design • Survey • Discussions 25 The result of the first two questions 20 15 Counts 10 5 0 Fair Very Good Excellent Poor Good The non-parametric Wilcoxon test indicated no significant differences between the medians of the two distributions (p=0.2311 > 0.05).
Discussions • Introduction • App-Design • Survey • Discussions • An impasse resulted in a compromise, where both options are offered in the Settings, leaving the choice to the users. • A famous historical case is the continued adoption of left-side driving by Britons - a leftover from the horse riding days, where left-side riding accommodated sword handling in moments of danger. • The case we report here is a historical deja vu at a small scale, evolving in front of our eyes, which provides the opportunity for and in-depth study and intervention.
