However, disability voices and research suggest limited effectiveness, greater distancing, and exclusion. Despite this, the simulation of physical limitations, including that of aging, continue to be used under the assumption that physical tasks and usability ratings do not significantly differ in simulation. In this experiment, age- and sex-matched older adults who use and do not use a manual wheelchair (MWC) are instructed to independently perform a self-paced parallel park using an MWC. The total clearance between obstacles required to perform a collision-free trial was recorded. Thirty-eight volunteers were recruited (MWC-user n=15; Simulated Impairment [SI] n=23). Higher clearance was required by the MWC group, suggesting the use of simulated impairment for motor tasks may result in bias. Open-ended questions revealed self-centered viewpoints, supporting literature that raises inclusion concerns regarding views of an “Other” group. Overall, our results support the direct engagement of target populations during early design to appropriately define user perspectives and needs. Designers should work with the community of people who face limitations rather than substituting their voices with those who may not accurately represent all of their consumer needs.","PeriodicalId":74544,"journal":{"name":"Proceedings of the Human Factors and Ergonomics Society ...

The findings revealed that there was no significant difference in cognitive workload between the partially automated mode and manual mode in both objective and subjective measures. Our study expands the literature on the effects of partially automated vehicles on cognitive workload by using DRT and NASA-TLX.

With current advancements in the transportation system, particularly the increasing penetration of various levels of automation, the need to communicate intentions has become even more demanding and complex. Thus, it is critical to investigate the limitations and consequences of the existing communication channels and examine the need for improved communication. This study focused on two representative event types: lane change/merge and stop sign-controlled intersection in the SHRP 2 NDS dataset. Communication was deemed essential to the successful navigation of these maneuvers. Through exploratory analysis of driving behavior, insights were gained into the prevalence of lack of communication (LOC) among target events. Identified LOC events were further classified based on the scenario type. Moreover, descriptive observations of the interaction between drivers in these situations were developed and categorized.","PeriodicalId":74544,"journal":{"name":"Proceedings of the Human Factors and Ergonomics Society ...

During the automation-to-human transition process, hazard avoidance plays an important role after human drivers regain the vehicle control. This study applies the multilevel Hidden Markov Model to understand the hazard avoidance processes in response to static road hazards as continuous processes. The three-state model—Approaching, Negotiating, and Recovering—had the best model fitness, compared to the four-state and five-state models. The trained model reaches an average of 66% accuracy rate on predicting hazard avoidance states on the testing data. The prediction performance reveals the possibility to use the hazard avoidance pattern to recognize driving behaviors. We further propose several improvements at the end to generalize our models into other scenarios, including the potential to model hazard avoidance as a basic driving skill across different levels of automation conditions.","PeriodicalId":74544,"journal":{"name":"Proceedings of the Human Factors and Ergonomics Society ...

Appropriate design of AV explanations could promote drivers’ acceptance, trust, and SA, enabling drivers to get more benefits from the technology. This study investigated the effects of error type and information type of AV explanations on drivers’ trust and SA. We recruited 300 participants for an online video study with a 3 (information type) × 2 (error type) mixed design. Linear mixed model analyses showed that compared with false alarms, misses were associated with more trust decrease after the error and more trust decrease after the post-error recovery. Compared with why information, how information was associated with lower SA generally and risked potential over-trust in false alarms. Therefore, we recommend deploying AV decision systems that are less miss-prone and including why information in AV explanations.","PeriodicalId":74544,"journal":{"name":"Proceedings of the Human Factors and Ergonomics Society ...

Considering environmental constraints, the system architecture promotes efficient cross modal communication between the mission control center, other astronauts, and the user interface. Currently, the system utilizes a hands-free modality such as speech recognition. Throughout the design process, we conducted heuristic evaluations on a low-fidelity prototype. Then, we implemented HARVIE into a high-fidelity prototype on the HoloLens 2 and utilized the Rapid Iterative Testing & Evaluation (RITE) method for human-in-the-loop testing. Lastly, we evaluated our final design at NASA Johnson Space Center.

Prior research has used individual differences—trust propensity and complacency—to explain this divergence. We argue that bifurcation as an outcome of a dynamic system better explains trust divergence. Linear mixed-effect models were used to identify features to predict trust (i.e., individual differences, automation reliability, and exposure). Individual differences associated with trust propensity and complacency increases the R 2 of the baseline model by 0.01, from R 2 = 0.40 to 0.41. Furthermore, the Best Linear Unbiased Predictors (BLUPS) for random effect of participants were uncorrelated with trust propensity and complacency. In contrast, modeling trust divergence from a dynamic perspective, which considers the interaction between reliability and exposure along with the individual by-reliability variability fit the data well ( R 2 = 0.84). These results suggest dynamic interaction with automation produce trust divergence and design should focus on state dependence and responsivity.","PeriodicalId":74544,"journal":{"name":"Proceedings of the Human Factors and Ergonomics Society ...
