“…Another main drawback of the Kinect skeleton is in a very non-anthropometric kinematic model with variable limb lengths. Although this does not seem to be a problem for ergonomic assessment by OWAS and others applications where less information is needed (Obdrzálek et al, 2012), the use of other methods such as RULA, REBA, LULA or PATH (Buchholz et al, 1996) requires to measure joint rotations and an improved kinematic model. MicrosoftÔ recently announced the launch of Kinect 2Ô.…”

a b s t r a c tThis paper examines the potential use of KinectÔ range sensor in observational methods for assessing postural loads. Range sensors can detect the position of the joints at high sampling rates without attaching sensors or markers directly to the subject under study. First, a computerized OWAS ergonomic assessment system was implemented to permit the data acquisition from KinectÔ and data processing in order to identify the risk level of each recorded postures. Output data were compared with the results provided by human observers, and were used to determine the influence of the sensor view angle relative to the worker. The tests show high inter-method agreement in the classification of risk categories (Proportion agreement index ¼ 0.89 k ¼ 0.83) when the tracked subject is facing the sensor. The camera's point of view relative to the position of the tracked subject significantly affects the correct classification of the postures. Although the results are promising, some aspects involved in the use of low-cost range sensors should be further studied for their use in real environments.

“…Ergonomic exposure assessment protocols based on work sampling strategies with observations over extended periods of time were found suitable to accurately estimate exposure to workplace hazards associated with construction work [3]. Forde and Buchholz conducted quantitative exposure assessments for seven construction ironwork tasks, including tying rebar in a highway base layer [4].…”

BACKGROUND: Work-related Musculoskeletal Disorders (MSDs) affect the well-being of workers. Unfortunately, user requirements for design to reduce workplace risk factors for MSDs are not always effectively communicated to designers creating a mismatch between the user requirements and what is ultimately produced. OBJECTIVE:To understand the views of practitioners of design and ergonomics regarding tools for participatory design and features they would like to see in such tools. METHODS:An online questionnaire survey was conducted with a cohort of practitioners of ergonomics and design (n=32). In-depth interviews were then conducted with a subset of these practitioners (n=8). To facilitate discussion, a prototype integrated design tool was developed and demonstrated to practitioners using a verbalized walkthrough approach. RESULTS:According to the results of the questionnaire survey, the majority (70%) believed an integrated approach to participatory design would help reduce work-related MSDs and suggested ways to achieve this, for example, through sharing design information. The interviews showed the majority (n=7) valued being provided with guidance on design activities and ways to manage and present information. CONCLUSION:It is believed that an integrated approach to design in order to help reduce work-related MSDs is highly important and a provision to evaluate design solutions would be desirable for practitioners of design and ergonomics.Keywords: design process; participatory design; design methods IntroductionWork-related musculoskeletal disorders (MSDs) affect the health and well-being of workers and can hinder growth in the industrial sector causing staggering expense [1]. Attempts have been made to reduce MSDs in the working population, for example, intervention programs [2-5], standards [6] and guidelines [7,8] have been developed to try to eliminate workplace risk factors, but they are still commonplace. Research suggests that more intervention approaches are required and that methods currently being used to reduce the risk of MSDs among workers could be improved [9,10]. Adherence to ergonomics in design together with a full assessment of work systems would help curb work-related MSDs [1].A drawback in the design process is the mismatch between user requirements to reduce workplace risk factors for MSDs and what is ultimately produced [11,12]. Stakeholders in the design process include users that directly interact with equipment and processes and practitioners such as engineers, designers and others such as ergonomists, occupational health professionals and health and safety personnel that may be involved in the design process and influence design decisions. However, the involvement of such professionals varies [13] and 2 user focused design requirements to reduce workplace risk factors for MSDs are not always effectively and efficiently conveyed preventing appropriate solutions being incorporated in the next generation of designs. Thus, a mechanism to fill this void between the users and the ...
