BGU researchers develop webcam tool to improve office worker posture

03.08.2011
A multidisciplinary team at Ben-Gurion University of the Negev has developed a new training method using a desktop webcam to improve ergonomic posture and reduce the risk of musculoskeletal disorders (MSD) among office workers using computers.

According to an article in Applied Ergonomics in the forthcoming issue, a group of 60 workers received both office training and an automatic frequent-feedback system that displayed a webcam photo of a worker's current sitting posture alongside the correct posture photo taken during office training.

The results showed that both training methods provided effective short-term posture improvement; however, sustained improvement was only attained with the photo-training method. Both interventions had a greater effect on older workers and on workers suffering more musculoskeletal pain. The photo-training method had a greater positive effect on women than on men.

"To maintain the effectiveness of an ergonomic intervention for the long term, the intervention should be a continuous process, which includes frequent feedback," the researchers explain. "This new ergonomic method can also result in preventing MSD among workers and reduce financial loss to their employers."

The method of frequent and continuous feedback using photos was found to be effective in improving the sitting posture of computer workers over time. These conclusions have direct implications for many workers in industry and services.

It is recommended that such self-modeling, photo-training software be installed on the worker's computer to provide frequent and long-term feedback. The research suggests that this should be implemented in addition to the conventional office ergonomic intervention that combines specialized ergonomic training and workstation adjustments.

In light of the differences in effect between men and women, combining supplementary feedback targeted to different audiences should be considered. For example, it is recommended to consider adding more detailed feedback that would call attention to deviations from the desired pose for each of the body segments, and evaluate its deferential effect on both genders over the long term.

The multidisciplinary team of researchers included Dr. Meirav Taieb-Maimon and Prof. Bracha Shapira from BGU's Department of Information Systems Engineering, Prof. Julie Cwikel of the Center for Women's Health Studies and Promotion, Dr. Ella Kordish from occupational health and epidemiology and Dr. Naftali Liebermann from orthopedic surgery at Soroka University Medical Center. This study was funded by a grant from Israel's Ministry of Industry, Trade and Labor to support the incorporation of video and computer-based technology to address occupational health problems.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
