The Effect Of Interruptions On Primary Task Performance In Safety-Critical Environments, Cheryl Ann Nicholas Nov 2016

The Effect Of Interruptions On Primary Task Performance In Safety-Critical Environments, Cheryl Ann Nicholas

Doctoral Dissertations

Safety critical systems in medicine utilize alarms to signal potentially life threatening situations to professionals and patients. In particular, in the medical field multiple alarms from equipment are activated daily and often simultaneously. There are a number of alarms which require caregivers to take breaks in complex, primary tasks to attend to the interruption task which is signaled by the alarm. The motivation for this research is the knowledge that, in general, interrupting tasks can have a potentially negative impact on performance and outcomes of the primary task. The focus of this research is on the effect of an interrupting …

Leveraging Smart Infusion Pump Data For Workflow, Patient Care And Usability Improvement In Human Factors, Yan Ni Ding, Denny Yu, Poching Delaurentis, Kang-Yu Hsu, Joon Hong Kim

The Summer Undergraduate Research Fellowship (SURF) Symposium

Infusion pumps are medical devices that deliver fluids like medication, and nutrients in a precise, timely, and controlled manner that is critical to patient care. It is widely used in clinical settings especially in hospitals, nursing homes and sometimes at home. Smart infusion pumps technology are supposed to be reduce nurses’ workload, but due to the recurring number of alarms which disrupt the workflow of the infusion process, most nurses prefer to use the traditional infusion pumps or work-around the safety features of the smart pumps. Thus, the aim of this research is to leverage Smart Infusion Pump data to …


Human-Robot Interaction: Proximity And Speed—Slowly Back Away From The Robot!, Keith R. Macarthur, Kimberly Stowers, Peter A. Hancock Jul 2016

Human-Robot Interaction: Proximity And Speed—Slowly Back Away From The Robot!, Keith R. Macarthur, Kimberly Stowers, Peter A. Hancock

Keith Reid MacArthur

This experiment was designed to evaluate the effects of proximity and speed of approach on trust in human-robot interaction (HRI). The experimental design used a 2 (Speed) × 2 (Proximity) mixed factorial design and trust levels were measured by self-report on the Human Robot Trust Scale and the Trust in Automation Scale. Data analyses indicate proximity [F(2, 146) = 6.842, p < 0.01, partial ŋ 2 = 0.086] and speed of approach [F(2, 146) = 2.885, p = 0.059, partial ŋ 2 = 0.038] are significant factors contributing to changes in trust levels.
