Tidskriftsartikel (refereegranskat)abstract
- Adaptive cruise control (ACC), through the partial automation of the longitudinal driving task, is expected to increase driving comfort and assure a positive impact on road safety. Previous research showed that some side effects can result from the usage of the ACC. Those studies were mainly performed with drivers who never used the ACC before taking part in the experiments. For this reason, little information is available about how the ACC actually affects the driving task of real users of the system. In order to investigate the topic, two focus groups sessions were performed in Portugal with 13 ACC drivers. The findings revealed users’ satisfaction regarding the comfort and safety provided by the system. On the other hand, some cases of behavioural adaptations to the system were reported. Further research on the problem domain is suggested.

Evaluating usability problems and use errors in ergonomic products: comparing analytical methods and usability test
- 2017
-
Ingår i: International Journal of Human Factors and Ergonomics. - 2045-7804 .- 2045-7812. ; 5:1, s. 1-21
-
Tidskriftsartikel (refereegranskat)abstract
- In product design, it is important to consider presumptive usability problems and use errors. A number of evaluation methods are available, analytical as well as empirical. This study aimed to investigate how well the results from the two analytical methods, enhanced cognitive walkthrough (ECW) and predictive use error analysis (PUEA), match the results of a usability test. A vacuum cleaner and an office chair were used in the evaluations. The ECW predicted 90% of the usability problems and the PUEA predicted 58% of the use errors that were identified in the usability test. For the ECW, the difference is that the method only investigates the correct way to perform a task, whereas for the PUEA the difference depends on the chosen user as well as the evaluator's creativity in making and predicting errors. To conclude, these methods are valuable tools in early phases of the product development process.

Tidskriftsartikel (refereegranskat)abstract
- The study addresses the prototyping, user testing, re-design, and re-testing of an office furniture concept following a research through design approach. The concept was intended to enable a positive user experience of control over sound stimuli and related distractions in flexible offices. The aims were: (i) to explore design opportunities in relation to experience of control; and (ii) to gain a deeper understaning of how to design for such positive experiences. The results show a limited impact on the experience of control over sound stimuli in the offices where the concept was tested, and a noticeable positive effect on control over privacy, visual distraction, and (to a lesser extent) work tasks. In this sense, the concept was meaningful for the users and opened up new opportunities for control over stimuli in flexible offices. The context, temporality of user experiences, and prototype fidelity were the keys to explaining the results.

Tidskriftsartikel (refereegranskat)abstract
- This study reports on a group of university employees, six months after their relocation from cell-offices into a combi-office. Data from interviews, observations and planning documentation was collected to gain an in-depth understanding of how employees use their office landscape and why. Activity theory was taken as framework for the analysis. The findings show that the new office landscape was perceived to be more flexible and capable of supporting employees’ activities. The overall occupancy was low and backup spaces, such as quiet rooms, were barely used. Matches and mismatches between the employees, their activities and the office were identified that explain the occupancy rates and why spaces such as quiet rooms were unpopular spaces. This paper contributes with rich detail on the use of a flexible office landscape in a university context and shows the usefulness of activity theory in the study of employee-office interactions.

Tidskriftsartikel (refereegranskat)abstract
- Health care organizations in Sweden are recently reorienting toward horizontal organization around care processes. The aim was to investigate how implementation approaches for improvements of care processes in line with lean production (LP), at strategic and operative levels, in hospitals are associated with the consequences for working conditions and stress-related health among the employees. Five hospitals working with improvements to care processes were tracked: questionnaires to employees (n=1326) and interviews at strategic and operative levels at baseline and follow-up. The process redesign implementation strategies varied between the strategic and operative levels. There were associations between a higher degree of LP at operative level and increased work resources and decreased work demands. Physical, cognitive and mental stress-related symptoms were only weakly associated with strategic or operative LP initiatives. There was evidence of more beneficial or improved working conditions in relation to strategic or operative initiatives, approaches to degree of LP.

Assessing and improving supervisory behaviours at standardised meetings using self-recorded video and the operant supervisory taxonomy index
- 2024
-
Ingår i: International Journal of Human Factors and Ergonomics. - : Inderscience Publishers. - 2045-7804 .- 2045-7812. ; 11:2
-
Tidskriftsartikel (refereegranskat)abstract
- The aims of this study were to use the operant supervisory taxonomy index (OSTI) with self-recorded videos: 1) to assess three crucial supervisory behaviours at recurrent workplace meetings; 2) to assess an intervention to increase supervisors' use of performance consequences; 3) to demonstrate how using OSTI with video for studying supervisor-employee interactions contributes to the field of human factors and ergonomics. Eight supervisors at a technical company video-recorded themselves at standardised daily staff meetings for ten weeks (360 videos, in total). All supervisors increased their delivery of performance consequences per meeting after participating in weekly sessions focusing on their use of this behaviour. The use of the crucial supervisory behaviours varied within and between supervisors. A combination of self-recorded videos over time and OSTI is a useful method for objectively analysing supervisor performance in detail and can contribute to improving supervisory behaviours and their impact on performance and health.

Tidskriftsartikel (refereegranskat)abstract
- This study analysed a series of workshops and explored prerequisites for interdisciplinary co-design among industrial designers, design engineers and users in the development of a novel medical device. Presented as a case study, this paper focus on what affects participants’ transformative processes towards genuine participation in co-design processes. Based on activity theory, we suggest that co-design activities have to support not only users, but all participants, shifting their perspectives beyond their own domain’s rules, motives, objects and division of labour, i.e., beyond their own activity system, to support users’ participation as equal members in design teams. We propose that genuine co-design requires a holistic approach where a neutral arena, an impartial facilitator, clear rules of play, along with representational artefacts as mediating tools in the formation of a new collective activity system to foster equality, mutual value and long-term knowledge generation. Such approach requires a process over time.

Tidskriftsartikel (refereegranskat)abstract
- A main challenge to the successful wide scale introduction of self-driving vehicles is users' trust in automation technology. This study's primary aim was to investigate whether auditory displays can enhance users' trust when they ride in self-driving cars. Twenty-eight subjects participated in an experiment utilising a virtual reality simulation. All subjects rode in a virtual vehicle with and without an auditory display. The display contained signals that provided information about the intentions of the car, as well as other road users that the car focused on. Participants' responses were collected during and after the rides. The results suggest that auditory displays can be useful to improve users' trust. Furthermore, the designed auditory display received high scores in terms of user acceptance. These results have implications for the interaction design of self-driving cars and can guide future auditory display research.

Tidskriftsartikel (refereegranskat)abstract
- The purpose was to explore if sense of coherence (SOC) theory can be used in human factors ergonomics (HFE) practice as a leadership approach to decrease the rate of sick leave and rehabilitation cases and increase work attendance among assembly personnel without impeding productivity. Via three studies carried out at the Swedish truck manufacturer Scania, we investigated the company’s key performance indicators and documented meetings with managers during the intervention. The results show that SOC can be used in HFE practice and that productivity, quality and attendance at work increased, while rehabilitation cases decreased. Our conclusion is that a health promotion approach among managers is essential in a lean organisation that aims to reduce waste in the company and optimise human capability and thereby productivity. SOC theory can support the creation of workplaces that are high performing and healthy, starting with concerns for the people creating the output.

Tidskriftsartikel (refereegranskat)abstract
- A participatory ergonomics program enables a company to engage employees in its preventive strategy. This paper presents Ergo@Office, 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, Ergo@Office 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.

Tidskriftsartikel (refereegranskat)abstract
- In this paper, we promote and motivate research on user experience (UX) in the domain of rail, more specifically for the workers engaged in the daily operational parts of executing train traffic. UX aspects have often been overlooked in the design and use of technology within the workplace, particularly in safety-critical work domains. Here, we provide an overview of current UX research at work and outline a roadmap with seven facets for future research within the domain of operational train traffic that is in alignment with the need for further investigation into UX at work. We hope future research will contribute to a deeper understanding of how positive experience at work provides additional means of enhancing engagement and improving safety management in workplaces in general and for the work in operational train traffic specifically.

Ergonomic evaluation of long–shafted tools used in horse stables: the effects of shaft length variation and work technique on working posture
- 2012

Tidskriftsartikel (refereegranskat)abstract
- This study examined the physical demands involved in manual manure handling in horse stables when using two different long–shafted work tools, a shavings fork and a manure fork, and investigated how variations in shaft length affected the physical workloads of the user. The methods used were generic task specification (GTS) and the Jack human simulation system (JACK). In general, adding 10 cm to the 125 cm length of the existing manure fork shaft gave the highest reduction in load on the back, especially regarding compression forces, irrespective of body height, sub–task and work technique. Simulations with the shavings fork (length 150 cm) showed that correcting user work technique considerably reduced the load on the back. Thus, it is important to consider both the shaft length of a tool and the work technique when attempting to reduce the physical work load for users.

Tidskriftsartikel (refereegranskat)abstract
- Motion sickness may be a factor detrimental to the experience of self-driving cars. This study investigates whether auditory displays can support in lowering passengers' feeling of motion sickness by allowing them to anticipate upcoming manoeuvres. Twenty participants took part in the study and rode on a specially designed test track with and without auditory display while performing a reading task. The display provided information about upcoming car manoeuvres, which were identified as being motion sickness inducing and the sounds were designed to resemble the actual sound of the manoeuvres taking place. Sounds representing acceleration, deceleration and left and right turns were played slightly in advance of the upcoming manoeuvre. Participants rated their motion sickness at regular intervals during the ride as well as before and after the ride. The results showed that illness ratings in the auditory display condition were statistically lower significantly compared to the condition without sound. The sounds were also judged as intuitive and helpful by the users who reported willingness to use them when riding autonomous cars in the future, especially while reading or working. These results have implications for the interaction design of self-driving cars and can guide future auditory display research.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- A variety of factors, such as sound, vibration and seating system influence the perceived overall ride comfort in passenger cars. However, these influences are not constant across different driving scenarios. The purpose of this study is to identify how human experiences regarding sound and vibration varied in eight different driving scenarios. A user study was conducted with ten participants in a combustion passenger car. The results showed that dynamic discomfort was affected by induced body movement, annoying sounds and the discordance between sound and vibration. Tyre-road noise and wind noise dominated the perceived sound annoyance at lower and higher speed, respectively. The vibration annoyance was mostly judged by induced body movements. The conclusion was that the influences of sound and vibration on perceived ride comfort change in different driving scenarios, and thus, overall ride comfort should be evaluated in different ways depending on the chosen driving scenario.

Tidskriftsartikel (refereegranskat)abstract
- “Lean production” has become a prevalent rationalization methodology in healthcare. Value Stream Mapping (VSM) is a commonly used Lean tool to identify non-Value-Adding-Work. VSM is a participatory tool. Thus it may offer an opportunity to combine interventions for improved performance and ergonomics. The aim of the present exploratory study is to report observations that seem to play significant roles as inhibitors and facilitators for proper intervention processes when using VSM. Seven hospital wards have been investigated in Denmark, Iceland and Sweden. Information was obtained by screening key hospital documents and interviewing participants in and around the VSM processes. Nine tape-recorded interviews were performed. The results tentatively point to the facilitating effect on the VSM process by emphasizing involvement and decision-making among the participants, 1st line manager support and engagement, allocation of sufficient resources, work environment issues as part of the VSM methodology and VSM routines that are well-established and broadly accepted.

Tidskriftsartikel (refereegranskat)abstract
- Personalisable in-vehicle interfaces offer a flexible way to tailor content and appearance of the interface to suit the driver and bridge a number of functional and emotional issues. A questionnaire based on the technology acceptance model (TAM) was handed out to 137 respondents to study whether personalisable vehicle human-machine interfaces (HMIs) would be accepted for use in vehicles and also to investigate whether the emotionally-associated construct product attachment affects the behavioural intention. The main findings indicate that personalisable systems were fairly well accepted for use in vehicles and a system comprised of personalisable modes displayed the highest behavioural intention. Moreover, as personalisation offers a closer, more emotional and personal connection to the product, a person's attachment to a product was shown to affect the intention to use the product.
