Ergonomic Challenges in Modern 21st Century Workplaces: The Evolution of Computer Use
Today, we see a significant shift in the way we work, particularly with the use of computers. This modern era brings new challenges and considerations for ergonomic standards. As technology advances, so do the tools we use in the workplace, and these changes require us to reassess our approach towards ergonomics.
The Rise of Wide Monitors and Multiple Screens
One notable trend is the increased usage of wide monitors and multiple monitors. While ergonomics standards were primarily developed in the 1990s, these standards were based on the design of square CRT monitors. Nowadays, people prefer wider monitors outside the range of traditional recommendations. However, this new trend introduces unique challenges. For instance, the design of wide monitors can place the neck in awkward postures, particularly when multiple wide screens are used. Sustaining such postures for prolonged periods can cause significant strain and discomfort.
Optimally, the neck should maintain a relatively straight posture when viewing the main monitor. This is the most neutral or optimal position. However, with wide monitors positioned vertically, the neck may need to bend backwards to view the top of the monitor, which is a common ergonomic concern. Furthermore, using mismatched monitors of different types and resolutions can complicate the setup and exacerbate these issues.
New Trends and Innovations
Another emerging trend is the use of orange tinted computer glasses. These glasses claim to reduce eyestrain. While I haven't conducted extensive research, this development is intriguing. Any insights or experiences shared by those who have tried these glasses would be greatly appreciated!
Building Movement into Your Day
Static and poor postures remain a significant challenge in modern workplaces. Ergonomic furniture and equipment can help, but it's essential to actively engage in building movement into your daily routine. Contemporary office furniture offers extensive adjustability, allowing users to adopt a variety of postures, from seated recline to standing. The key is to understand how to arrange your work interface to support different postures. The best posture is simply the next posture you adopt.
With the increasing amount of information processed on mobile devices, we can expect to see more postural issues. The "rolled shoulders" and "head forward" postures are indicative of prolonged mobile device usage. Work organizations can play a crucial role by encouraging the use of the appropriate device for specific tasks. For instance, short messages, passive information consumption, and "checking in" can be done on mobile devices. However, tasks that require detailed research or remote collaboration are better suited for stationary screens and keyboards, such as laptops or desktops.
Emerging Technologies and Posture Related Issues
As virtual and augmented reality (VR/AR) technologies enter the workplace, we should be vigilant about the postural issues they may introduce. While VR/AR headsets have become lighter and more mobile, many applications, particularly those involving 3D virtual design or manufacture, still require the headsets to be tethered, adding strain to the neck and shoulder girdle. Additionally, there are unresolved safety concerns related to an obscured or reduced field of view of the real world. Working in a virtual environment can be less enjoyable and productive when unaware of real-world surroundings.
These are the key ergonomic concerns that come to mind when considering computer work in the 21st century. As we continue to evolve in our work environments, it's crucial to stay informed about these issues and to adapt our strategies accordingly.
