Abstract
Potential benefits of multiscreen and multiple device environments were assessed using three different computing environments. A single factor, within-subject study was conducted with 18 engineering students in a laboratory experiment. Three levels for the computing environment factor included one with a desktop computer with a single monitor (control, condition A); one with a desktop with dual monitors, as well as a single tablet computer (condition B); and one with a desktop with a single monitor, as well as two tablet computers (condition C). There was no statistically significant difference in efficiency or workload when completing scenarios for the three computing environments. However, a dual monitor desktop with a single tablet computer (B) was the ideal computing environment for the information-rich engineering problem given to participants, supported by significantly fewer errors compared to condition C and significantly higher usability ratings compared to conditions A and C. A single desktop monitor with two tablet computers (C) did not provide any advantage compared to a single desktop monitor (A).
Highlights
As having more than one computing device and/or monitors is becoming more feasible for individuals, a future trend is the of adoption of a multiscreen and multiple device approach to cope with distractions and multiple tasks
A dual monitor desktop with a single tablet computer (B) was the ideal computing environment for the information-rich engineering problem given to participants, supported by significantly fewer errors compared to condition C and significantly higher usability ratings compared to conditions A and C
Post-hoc analysis showed that the difference between conditions B and C was the only significant difference (Wilcoxon Signed Ranks Test); participants committed 40% more errors with condition C compared to condition B
Summary
As having more than one computing device and/or monitors is becoming more feasible for individuals, a future trend is the of adoption of a multiscreen and multiple device approach to cope with distractions and multiple tasks. This may seem counterintuitive, more screens and possibly more devices may help focus one’s attention rather than serve as a distraction, making multiple tasks viewable at a glance across multiple screens and devices (Thompson, 2014). Coordination of multiple computing devices and screens is a strategy that may potentially improve one’s performance in an information-rich environment by focusing their attention and reducing their mental workload.
