Understanding the Workplace Experience Through Sensor Tracking of Behavior Speaker: Gloria Mark ( ). Understanding the workplace experience is important in order to develop solutions to improve health, mood and performance. However, cognitive, emotional, and behavioral measurements of the workplace experience until recently have been constrained by methodologies based on infrequent measurements or self-reports. The ongoing revolution in the development of sensor technologies is enabling new ways to measure human behavior in situ with precision. In this talk Gloria Mark presents research from studies which tracked participants in the workplace. She took a multi-faceted view of the workplace experience with a mixed-methods approach using sensors, bio-sensors, EMA, Sensecams, actigraphs, and repeated surveys collecting data on computer activity, affect, stress, focus, sleep, physical activity, productivity, and other factors. This methodology has enabled her to develop models of workplace mood, stress, communication, attention focus, multitasking, email use and temporal patterns of use. The research shows that there are consequences of having access to so many digital information sources: they continually compete for attention. People continually switch our attention among different information streams, applications and devices. Gloria Mark discusses the value and challenges of multi-faceted quantitative measures of workplace (and other) behavior as we move towards designing interdisciplinary research to study, and design for, digital media use.
