Positive effects of blue light on motor coordination in older adults: A pilot study
CONCLUSION: Blue-enriched lighting demonstrates a novel approach to positively impact postural control and motor coordination in older adults. By impacting metrics associated with fall risk, light interventions may provide a clinical countermeasure to decrease the human costs of falls.PMID:37866103 | DOI:10.1016/j.apergo.2023.104156 (Source: Applied Ergonomics)

Identifying interaction types and functionality for automated vehicle virtual assistants: An exploratory study using speech acts cluster analysis
This study explores 'interaction types' used for this complex human-machine transaction, by analysing how situation information is conveyed and reciprocated during a transfer of control scenario. Two human drivers alternated control in a bespoke, dual controlled driving simulator with the transfer of control being entirely reliant on verbal communication. Handover dialogues were coded based on speech-act classifications, and a cluster analysis was conducted. Four interaction types were identified for both virtual assistants (i.e., agent handing over control) - Supervisor, Information Desk, Interrogator and Converser, and d...

Improving wayfinding in hospitals for people with diverse needs and abilities: An exploratory approach based on multi-criteria decision making
Appl Ergon. 2023 Oct 15;114:104149. doi: 10.1016/j.apergo.2023.104149. Online ahead of print.ABSTRACTHospital wayfinding systems that are based solely on signage do not provide adequate solutions for wayfinding needs, especially for users with impairments. Moreover, the interaction between user characteristics and the inner space of the building also determines wayfinding efficiency. The aims of this study, therefore, were to identify architectural features that affect spatial orientation and wayfinding behaviors; demonstrate the implementation of a multi-criteria decision-making (MCDM) approach for improving wayfinding in...

Effects of virtual heights, dual-tasking, and training on static postural stability
This study aimed to investigate the impact of virtual heights, DT, and training on static postural stability. Twenty-eight volunteers' balance at seven virtual environments [VE; ground (G), altitude 1 (A1), edge 1 (E1), altitude 2 (A2), edge 2 (E2), altitude 3 (A3), and edge 3 (E3)] were recorded during single-tasking (ST) and DT over three days. Independent variables were analyzed using a 7 (VE) x 3 (DAY) x 2 (TASK) factorial repeated measures ANOVA. Greater postural sway was observed in A3 and E1, on DAY 1, and during DT. The study demonstrated static postural stability deteriorates at higher virtual altitudes and during...

Thermoregulatory and perceptual implications of varying torso soft armour coverage during treadmill walking in dry heat

We hypothesized that armour configurations with lower levels of torso soft armour coverage attenuate physiological and perceptual responses during exercise in the heat.

Road safety: The influence of vibration frequency on driver drowsiness, reaction time, and driving performance
Appl Ergon. 2023 Oct 7;114:104148. doi: 10.1016/j.apergo.2023.104148. Online ahead of print.ABSTRACTDriver drowsiness is a factor in at least 20% of serious motor vehicle accidents. Although research has shown that Whole-Body Vibration (WBV) can induce drowsiness in drivers, it is unknown whether particular frequencies are more problematic. The present study systematically investigated the influence of WBV frequency on driver drowsiness. Fifteen participants each undertook six 1-h sessions of simulated driving while being subjected to WBV of either 0 Hz (no vibration), 1-4 Hz, 4-8 Hz, 8-16 Hz, 16-32 Hz or 32-64 Hz. Subject...
