Next Generation Real-Time Distributed Manufacturing Service Systems Using Digital

Process Planning and GPU-Accelerated Parallel Computing nsf

In collaboration with the CASS Lab in the School of Mechanical Engineering, this project will enable the scaling of  novel manufacturing analysis applications in a smart, human-centered manufacturing service system. This manufacturing service system will enable highly functioning relationships between a range of users, including service consumers (e.g., designers, entrepreneurs, makers) and service producers (e.g., manufacturers).

Prospective Memory in Dynamic Environments: The Role of Uncertainty

This project focuses on how uncertainty in dynamic environments (e.g., healthcare) influences how operators in such environments remember to execute important future tasks.


Prevention Epicenter of Emory and Atlanta Consortium Hospitals (PEACH)

Emory investigators will work with Georgia State microbiologists and human factors researchers at Georgia Tech to assess the transfer of a marker for Ebola and other pathogens when removing personal protective equipment (PPE) and look at steps in the process where errors could occur. The group will visit Georgia’s five state-designated Ebola treatment centers and work with healthcare workers at those sites to assess opportunities to improve safety for healthcare workers. Georgia Tech’s human factors group from the School of Psychology will focus on behavioral interactions with PPE to identify high-risk components of the suits or of the process used to don or doff them.

Pediatric ICU Nurses’ Strategies for Managing Threats in Acute Critical Care

nurses_with_patientNurses in the PICU must manage a variety of threats while maintaining performance in critical tasks. The purpose of this project is to investigate what strategies nurses are using to manage these threats. Nurses are interviewed using the Threat Strategy Interview (Durso et al., 2015) to elicit the strategies they use to manage each threat. In addition to eliciting strategies, the interview technique also elicits the cues that lead to each threat and strategy, as well as in what situations they would use one strategy over another.

Detection of Hospital Acquired Infections

infectionsThe purpose of this research is to investigate how nurses detect the threat of a hospital acquired infection and what kinds of cues or predisposing factors make a nurse more likely to detect an impending infection. In addition to the type of risk factors, the current research aims to investigate the role of experience and time pressure in accurate and timely detection.



Cognitive Task Analysis of Healthcare Providers Use of the Electronic Health Record System in a Pediatric Hematology/Oncology Clinic

epic photoThis study focuses on improving healthcare provider interactions with the electronic health record (EHR) in an ambulatory pediatric hematology/oncology clinic. We will interview physicians and mid-level practitioners on their feelings toward the current EHR used, perform a cognitive walk-through with various scenarios while using both the current EHR software and the ideal EHR software that the participant will create to best work with the scenario, and observe the providers using the current EHR software in clinic.

Investigating Run Through Switches among Remote Control Operators

CSX_ProjectImageThis project aims to understand the underlying issues related to run through switches in train yards, a very common and expensive error. The project aims to conduct behavioral observations to illuminate the opportunities for these errors as well as critical incident interviews to elicit the events and decisions that led up to an actual run through switch.


Using Interruptions to Study Prospective Memory Components in an Air Traffic Control Simulation

NextSim picOperators in dynamic environments, such as air traffic control, may often have to remember to perform certain tasks in the future (e.g., Loft, Smith, & Bhaskara, 2011).



Using Preview Information to Facilitate Complex Visual Search

jwa-baggage-screeningThe proposed study will examine whether previewing bags based on clutter metrics can lead to improvements in baggage screening performance. In addition, this study will explore whether the preview process is primarily driven by attention guidance or the limited capacity of visual working memory.



nextsim2It is difficult to do research in an environment that does not yet exist. The CEL has been contracted to develop a simulator that will allow researchers to collect data about air traffic control in a variety of possible futures.


Behavioral Interventions for Reducing Post-completion Errors in Safety-critical Systems

scenario003_switch&switchPointThis research investigates PCEs in the railroad industry and evaluates the effectiveness  of behavioral interventions designed to reduce PCEs.



Human Error Taxonomies

humanerrorWe are evaluating taxonomies from a variety of domains and investigating how they can be used to reduce human error.



Re-designing Rule Books and Forms to Increase Readability and Reduce User Error

FormsPicThe Cognitive Ergonomics Lab is working with CSX to re-design rule books to increase readability and retention.
