Machine learning methods for electromyography error detection in field research: An application in full-shift field assessment of shoulder muscle activity in apple harvesting workers
This study presented an alternative technique for processing electromyography (EMG) data with sporadic errors due to challenges associated with the field collection of EMG data. The application of this technique was used to detect errors, clean and optimize EMG data in order characterize and compare shoulder muscular load in farmworkers during apple harvesting in a trellised orchard. Surface EMG was used to take measurements from twenty-four participants in an actual field work environment. Anomalies in the EMG data were detected and removed with a customized algorithm using principal component analysis, interquartile rang...

Use of data-driven design for the development of knob-shaped handles in the context of impedance measurements
Appl Ergon. 2021 Sep 30;98:103575. doi: 10.1016/j.apergo.2021.103575. Online ahead of print.ABSTRACTIt can be inferred from hand-arm impedance analyses that the grip forces of users have a great influence on the transmitted vibrations. To determine this influence on test benches, the state of research suggests a cylindrical measuring handle. Since this shape is not suitable for all power tool handles, we develop a design for a knob-shaped measuring handle. The grip force applied to an orbital sander was measured in a test person study. The recorded data was combined with a 3D scan and evaluated by an algorithm which determ...

Individuals differ in muscle activation patterns during early adaptation to a powered ankle exoskeleton
This study examined individual muscle activation patterns during walking with a powered ankle exoskeleton. 60% of the participants were observed to reduce medial gastrocnemius activation with exoskeleton powered and increase with the exoskeleton unpowered during stance. 80% of the participants showed a significant increase in tibialis anterior activation upon power addition, with inconsistent changes upon power removal during swing. 60% of the participants that were able to adapt to the system, did not de-adapt after 5 min. Muscle activity patterns differ between individuals in response to the exoskeleton power state, and ...

Benchmarking occupational exoskeletons: An evidence mapping systematic review
DISCUSSION: This evidence mapping systematic review reveals that the assessment of occupational exoskeletons is a dynamic process, and provides literature-based assessment recommendations. The homogeneity and repeatability of future exoskeleton assessment experiments will increase following these recommendations. The current review recognises the value of variability in evaluation protocols in order to obtain an overall overview of the effect of exoskeletons on the users, but the presented framework strives to facilitate benchmarking the effect of occupational exoskeletons on the users across this variety of assessment pro...

Assessing the impact of autonomy and overconfidence in UAV first-person view training
Appl Ergon. 2021 Sep 30;98:103580. doi: 10.1016/j.apergo.2021.103580. Online ahead of print.ABSTRACTWith the rapid rise in unmanned aerial vehicles (UAVs) for military and civil first-person applications like infrastructure inspection, there is an increased need for skilled UAV operators. However, research on effective training of UAV pilots has not kept pace with the demand. How much autonomy should be onboard, how much training, and how much control humans should have are still points of debate. To help fill this gap, this paper examines how different training programs and levels of control autonomy affect training outco...

A head mounted augmented reality design practice for maintenance assembly: Toward meeting perceptual and cognitive needs of AR users
Appl Ergon. 2021 Sep 28;98:103597. doi: 10.1016/j.apergo.2021.103597. Online ahead of print.ABSTRACTHead Mounted Display (HMD) based Augmented Reality (AR) is being increasingly used in manufacturing and maintenance. However, limited research has been done to understand user interaction with AR interfaces, which may lead to poor usability, risk of occupational hazards, and low acceptance of AR systems. This paper uses a theoretically-driven approach to interaction design to investigate the impact of different AR modalities in terms of information mode (i.e. video vs. 3D animation) and interaction modality (i.e. hand-gestur...

Cue utilisation reduces the impact of response bias in histopathology
This study investigated whether higher cue utilisation is associated with a reduction in positive response bias in the diagnostic decisions of histopathologists. Data were collected from eighty-two histopathologists who completed a series of demographic and experience-related questions and the histopathology edition of the Expert Intensive Skills Evaluation 2.0 (EXPERTise 2.0) to establish behavioural indicators of context-related cue utilisation. They also completed a separate, diagnostic task comprising breast histopathology images where the frequency of abnormality was manipulated to create a high disease prevalence con...

Chair design for older immobile people: Comparison of pressure mapping and manual handling outcomes
Appl Ergon. 2021 Sep 27;98:103581. doi: 10.1016/j.apergo.2021.103581. Online ahead of print.ABSTRACTThe number of older adults unable to transfer or ambulate independently is increasing. High support chairs enable people experiencing loss of mobility to be mobile, but current chair designs are associated with global functional loss and pressure ulcers. This pilot study compared the functionality of a traditional design high support chair to a new design of motorised high support chair: 1) a motion laboratory study compared joint angles and pressure at the hip, knee, ankle, elbow and spine when pushing each chair, and 2) a ...

Effects of using a whole-body powered exoskeleton during simulated occupational load-handling tasks: A pilot study
This study assessed the effects of WB-PEXO use on back and leg muscle activities during lab-based simulations of load handling tasks. Six participants (4M, 2F) completed two such tasks (load carriage and stationary load transfer), both with and without a WB-PEXO, and with a range of load masses in each task. WB-PEXO use reduced median levels of muscle activity in the back (∼42-53% in thoracic and ∼24-43% in lumbar regions) and legs (∼41-63% in knee flexors and extensors), and mainly when handling loads beyond low-moderate levels (10-15 kg). Overall, using the WB-PEXO also reduced inter-individual variance (smal...
