Vigilance decrement is a relevant problem in critical contexts requiring occasional response after a prolonged period of inactivity. Although many studies describe boredom as the leading cause in depleting attentional resources, the understanding of its relationship with human performance has been limited by the unavailability of objective measures. This study attempts to overcome this limitation by focusing on fidgeting (namely, repetitive and involuntary body movements) as a behavioural correlate of boredom. A laboratory study was devised for comparing the individuals' performance to two versions of the same task characterised by two boredom levels. Movements were detected using accelerometers controlled by an Arduino board. Results showed that participants fidgeted more in the condition operationalised as less boring than in the more boring one. Result of this study are interpreted as supporting the idea that an increase in fidgeting may have a functional role, and that it might be used by individuals for introducing variability where it lacks. Overall, fidgeting appears to be promising candidate measure for that could be used in many operational settings for the assessment of the operator functional state.

The behaviour-based safety (BBS) approach is the 'use of science for changing the behaviour of an individual'. Implementation of BBS in an industry can significantly impact the entire organisation by reducing accidents. This research work is carried out at the work centre of waterwall panel fabrication area of heavy equipment manufacturing industry for improving workplace safety. Seven steps are used to implement the BBS approach. This work centre consists of 80 employees. Among those, 76 permanent workers like fitters, welders and crane operators are employed to carry out skilled work, and four contract labourers are employed to do unskilled work. The safety performance had improved from the baseline of 57.35% to 77.94% with the intervention of the BBS approach by the end of the 4th week. The results of this research work show that an effective measure of safety behaviour is important for positive behavioural changes among the workers.

Driving under unfamiliar traffic regulations (UFTR) is associated with an increased number of traffic accidents. To drive safely in such conditions, drivers need to adapt their prior knowledge to a new driving situation. This ability is called cognitive flexibility (CF). CF is influenced by the degree of handedness of the performer. The goal of this research was to develop a driving-assistance system that adapts the information it provides based on the handedness degree of drivers under UFTR. Two empirical studies were conducted in a driving simulator. The results of the first study indicated that left/mixed-handed drivers made significantly fewer errors that could be attributed to CF impairment than did strong right-handed drivers. Accordingly, we developed a driving-assistance system ('VEHand'), which provides drivers with useful feedback based on their handedness degree. The results of the second study indicated that VEHand significantly assisted strong-right handed drivers to correctly enter roundabouts and intersections.

Highly specialised personnel are dependent on others and diverse systems to perform error-free aircraft maintenance. Research has shown that the maintenance process can be improved to reduce errors and increase usability by using a mobile tool. The goal of this project was to draw on theories of user-centred design to explore what human factors issues for maintenance personnel can be addressed by a mobile tool to make the most out of maintenance planning, execution and follow-up. Military aircraft maintenance personnel at an air force unit were interviewed and observed. The following six problem areas that could be improved by the use of a mobile tool were identified: several information sources must constantly be consulted; information is constantly transferred between different locations and media types; technical documentation can be inconsistent and hard to access; there are strict hierarchies and certifications of personnel; the means of recording and transferring communicative information are insufficient; and there can be a long lag time for updates, error reporting and feedback of actions. A correctly designed mobile tool could solve these problems by combining all the information sources and recording relevant maintenance information.

Knee osteoarthritis (OA) is characterised by weakness and knee joint pain which may affect the performance in some activities of daily life like sit-to-stand. The aim of this study is to evaluate the strategies used by patients with knee OA when performing the 30-second chair stand test (30s-CST), and its association with their well-being. Twenty-one patients with knee OA were recruited. A 3D motion analysis system and two force plates were used to capture the kinematics and kinetics during the 30s-CST. The sit-to-stand and the stand-to-sit phases of the test were analysed independently. Significant differences were found (p < 0.05) between the first three and the last three repetitions in the 30s-CST for knee joint moment and power. No significant differences have been found between the most painful knee and the contralateral knee. The correlations found between the subscales of the knee injury and osteoarthritis outcome score (KOOS) and biomechanical parameters were significant (p < 0.05). Patients with the best score in KOOS subscales also showed better performance in the 30s-CST. Assistive technologies that maximise biomechanical strategies could be a valuable contribution to improve the well-being of these patients.

This study compared the effects of the prone, side-lying, and sitting positions during smartphone use. Positions can cause discomfort in the upper extremity musculoskeletal system. Thirty healthy young adults were recruited and instructed to type on a smartphone for 5 min in each position and 5 min rest between each position. Electromyography data acquired from the upper extremity muscles were analysed using the amplitude probability distribution function (APDF) method. Wrist and elbow joint angles were assessed using the motion analysis system (MyoMotion). In 50% of APDFs, the flexor carpi ulnaris muscle displayed higher muscle activity in the side-lying position, whereas the abductor pollicis brevis (APB) and extensor carpi ulnaris (ECU) muscles showed higher muscle activity in the sitting position. In 90% of APDF, the upper trapezius, ECU, and APB muscles showed higher muscle activity in the sitting position. Additionally, the side-lying position showed a neutral wrist extension angle of 0° compared to the prone and sitting positions (p < 0.05). Using smartphones in the side-lying position is recommended to reduce overuse of the upper-extremity muscles and poor alignment of the wrists.

Motorised mobility is evolving with the introduction of driving automation. The transition from driver to passenger requires a renewed focus on passengers and their needs while travelling, making passenger well-being a highly interesting concept to investigate. However, as of yet, it is unclear how passenger well-being may be operationalised, and which factors may contribute to passenger well-being in this domain. An exploratory study (n = 40) indicated that passenger well-being can be understood as current subjective well-being and that it can be measured reliably using self-reported measures. Further, multiple regression analyses showed that depending on how well the individual preferences are met by the vehicle interior, passenger well-being is either predicted by perceived safety, aesthetics and symbolism (preferences met) or by physical well-being and distrust (preferences not met).

Tonus dysfunction has been broadly investigated in post-stroke subjects through the evaluation of muscle resistance against stretching, however, its characterisation in functional context is challenging. This study aims to analyse the correlation between intrinsic stiffness, functional stiffness and antagonist co-activation at the ankle joint of post-stroke subjects. Both lower limbs of eight post-stroke participants were evaluated. Intrinsic stiffness was assessed during passive dorsiflexion by an isokinetic dynamometer, functional stiffness during upright standing on a force platform and antagonist co-activation was obtained in upright standing and postural phases of gait initiation and stand-to-sit through the electromyographic signal of ankle muscles. A significant positive correlation was found between antagonist co-activation of ipsilesional tibialis anterior/soleus pair in upright standing and functional stiffness (r = 0.810; p = 0.015; 1-β = 0.899). Antagonist co-activation seems to be related to functional stiffness in upright standing, suggesting the relevance of evaluating tonus dysfunction through motor control variables obtained under functional conditions.

Motion sickness is common within many forms of transport; it affects most of the population who experience some symptoms at some time. Automated vehicles (AV) offer productivity benefits but also increased incidence of motion sickness. There are mitigation methods with varying degrees of effectiveness to combating motion sickness. Bone conductive vibration (BCV) applied to the head is a proven motion sickness mitigation. It is not known if the level of vibration is important. Twenty-nine participants were subjected to normal urban driving whilst undertaking a 'gaze down' non-driving related task (NDRT) within an AV cabin whilst wearing the BCV device. High and low vibration settings were randomly chosen as were the seating positions in a between participants design. Twenty-five participants successfully completed the experiment. It was found that when the device is applied to the head, the time to nausea increased by up to a factor of 1.6 when set to high over low settings for highly susceptible participants. BCV did not improve task performance.

A participatory ergonomics program enables a company to engage employees in its preventive strategy. This paper presents [email protected], an integrated methodology devised for promoting continuous implementation of preventive measures while monitoring their effectiveness over time in a participatory manner. It consists of a straightforward and cost-effective resource which is primarily aimed at supporting the identification of the need for implementation of interventions for strategic prevention of musculoskeletal disorders. As a practitioner tool, [email protected] guides the deployment of a participatory approach to ergonomics in both the analysis as well as in the intervention phase. The implementation of the measures envisaged in this planning support framework result from teamwork between the OSHS (Occupational Health and Safety Services) and the employee whose work is under focus. The implemented measures should then be monitored, which will enable assessing their effectiveness and their adjustment to the labour setting in an up-to-date manner.
