Application of scaled world model for usability testing of fall arrest system in residential construction
Falls from heights in residential construction continue to be a leading cause of fatalities and severe injuries. Field studies are difficult to implement in residential construction, because companies are hesitant to allow observers on site to collect data while tasks are being conducted. Use of scaled world models has been recommended for experimental contexts that require high levels of ecological validity as well as internal (control) validity . In this project, we explored several attributes to design a scaled world model of residential roofing that would support controlled trials to evaluate...
