Team usability testing: development and validation of a groupware usability evaluation method
AbstractAs virtual teamwork became widespread, the importance of the usability of groupware has increased, as groupware must have high usability in order to properly support teamwork. Several studies have focused on the usability evaluation of groupware, yet, both in terms of science and practice, there is a lack of a method that, like existing empirical single-user methods, can be routinely applied in software development practice. The new Team Usability Testing method differs from previous methods in that it is an empirical method for evaluating synchronous (real-time) collaborative software that explores the team usabil...

Long and short-term characteristics of motion sickness: a test track investigation in a passenger car
This study explores the long and short-term characteristics of motion sickness, and uses self-reported motion sickness ratings at the end of car motion (the high point) and 3 s after the end of motion (the low point). Motion sickness ratings increased with task vs. no-task conditions. There is no significant correction between gender and maximum motion sickness in this study. Moreover, participants with high motion sickness susceptibility experienced increased motion s ickness. The difference between the low point and the high point is found to decrease as the motion sickness ratings increase. (Source: Cognition, Technology and Work)

Bridging system limits with human –machine-cooperation
AbstractHighly automated vehicles are subject to high expectations, encompassing safety improvements, efficiency in traffic flow and overall higher comfort. However, it is still unclear to what extent automation will be able to meet these expectations. Failures in sensors or erroneous data processing might bring an automated drive to a sudden stop. In such situations, the user of the vehicle could cooperate with the automated vehicle, to bridge system limits and directly continue the drive. How this cooperation process should be implemented and how much the vehicle user wants to be involved in this process is examined. In ...

Study on identification method of driver fatigue considering individual ECG differences
In this study, based on a driver's electrocardiogram signal, 17 feature indices were extracted as candidate features for driver fatigue classification from three aspects: frequency domain features, time domain features and non-linear features. In order to improve the generalization ability of the driver fatigue classification and recognition model and to reduce the negative impact of individual variability on the generalized model, the support vector machine (SVM) discriminant function information was introduced as the ranking evaluation criterion, the recursive feature elimination (SVM-RFE) algorithm was used as the searc...

IVIPAT: an in-vehicle information processing analysis tool to optimize user interaction flows
AbstractThis research introduces IVIPAT: an in-vehicle information processing analysis tool. The tool consists of a taxonomy (e.g., filter, search, interpret, monitor, decide) that can be used to carry out a task analysis with focus on information processing. This taxonomy is combined with a subjective mental demand rating scale to identify the intensity of each information processing step. The taxonomy is evaluated and revised based on the feedback ofN = 15 practitioners in Study 1 and then applied by a second sample ofN = 15 practitioners in Study 2. Results illustrate the added value of the tool: through the rat...

Emotion-matched in-vehicle assistants: an exploration in regulating drivers' incidental emotions and enhancing takeover performance and situational awareness
AbstractIn conditional autonomous driving, drivers are prone to experiencing incidental emotions during non-driving tasks, which are unrelated to driving decisions but may have negative effects on drivers' takeover performance. Voice assistants have been shown to regulate incidental emotions. Therefore, this study endowed the in-vehicle assistant with emotional voice capability, matching the emotional state of the driver in conditional autonomous driving, in order to explore the effect of regulating incidental emotions. Forty participants were enrolled in a driving simulation experiment. During the autonomous driving proce...

Modelling operator control work across traffic management domains: implications for interaction design
In this study, we have used JCF to map, and compare, cognitive joints, such as perceptions, decisions, and actions, in temporally challenging control situations in air traffic control, maritime vessel traffic service, and train traffic management. Data was collected collaboratively with traffic operators, focusing on (1) identifying challenging traffic situations and (2) jointly modelling the temporal decision-making patterns of these situations using simplified JCF. Post-analysis was done by breaking down the results into different processes and comparing domains to ascertain how operators maintain control. An intermediat...

Using problem-based exploratory training to improve pilot understanding of autopilot functions
AbstractPrevious research indicated a need to improve pilot training with regard to understanding of autopilot logic and behavior, especially in non-routine situations. Therefore, we tested the effect of problem-based exploratory training on pilots ’ understanding of autopilot functions. Using a moving-base flight simulator, general aviation pilots (n = 45) were trained to diagnose failures either without foreknowledge and guidance (exploratory group), without foreknowledge but with some guidance (exploratory-guidance group) or with foreknowledge and full guidance (control group). They subsequently performed six test sce...

Human-centered design and evaluation of a workplace for the remote assistance of highly automated vehicles
AbstractRemotely operating vehicles utilize the benefits of vehicle automation when fully automated driving is not yet possible. A human operator ensures safety and availability from afar and supports the vehicle automation when its capabilities are exceeded. The remote operator, conceptualized as remote assistant, fulfills the legal requirements in Germany as a Technical Supervisor to operate highly automated vehicles at Society of Automotive Engineers 4. To integrate the remote operator into the automated driving system, a novel user-centered human –machine interface (HMI) for a remote assistant’s workplace was devel...

Saccade response testing during teleoperations with a head-mounted display
AbstractHead-mounted displays (HMD) are increasingly used for teleoperating robots that stream video to the operator in real time. Eye-tracking sensors that can record saccadic eye movements non-intrusively are becoming a standard feature in HMDs. Saccade tests have been widely used in human factors research and can indicate operators ’ mental task resources. However, previous work has not yet explored saccade tests in robot teleoperation using an HMD. We implemented a saccade response test (SRT) and the Situation Present Assessment Method (SPAM) and conducted an experiment with 32 operators navigating a telerobot via an...

Influence of structural factors on employee cloud shadow IT usage during COVID-19 lockdown: a strain theory perspective
This study extended the strain theory by inculcating two structural factors (work pressure and work overload). Five hypotheses were postulated based on the model, which was empirically tested using quantitative research techniques. A survey method of data col lection was employed, and questionnaires were distributed to employees in Nigeria. SPSS was used for demographic analysis, and structural equation modeling was completed using SmartPLS. Results showed that work overload and work pressure each directly influence employee cognitive strain. While work overload and cognitive strain significantly impact employee cloud SIT ...

My synthetic wingman must understand me: modelling intent for future manned –unmanned teaming
AbstractWith advances in artificial intelligence, machine learning, and cognitive modelling, unmanned aircraft are expected to act as human-like wingmen in the near future. For fluent and effective manned –unmanned teaming, synthetic wingmen must be able to account for and adapt to their partners’ intent with little or no communication. To enable such abilities, it becomes crucial to identify the requirements that makes intent explainable to synthetic wingmen, necessitating approaches to describe and analyse intent from a human-centric perspective. To address this issue, this paper reports on findings from using Work D...
