Safer Laptop Computing
The ergonomic problems with laptops
Laptops have poor ergonomic design and because of this they are proving a particular challenge for safer computing, especially if used for anything more than short periods of time. Not surprisingly, many educationalists, ergonomists and health professionals are expressing alarm about the increasing level of RSI-type injuries affecting people using laptops.
In practice, laptops may be used in a way which places great strain on neck, shoulders, arms and hands. There may be a tendency to ignore the need for the workstation adjustments and good posture when working on laptops as they can be set up anywhere such as on a dining table, on one's lap or even on a bed. If this kind of work pattern becomes a habit, then the risk of a computer-related injury is very high.How can we prevent laptop injuries?
Safer computing involves being able to adjust the computer to the physical needs of the user, but with laptops this is more difficult, because keyboard, mouse and screen are integrated in one unit. Preventing injuries in the first place takes a little extra effort, but it is definitely worth following the basic guidelines suggested below, bearing in mind that computer-related injuries are painful, persistent and very debilitating. A great poster How Do You Sit at the Computer? can be downloaded from this website.
1. Set up your laptop on a desk like a conventional computer:
- Raise the screen by placing the laptop on a stand (available from office supplies shops) or some books, until the top of the screen is at the same level as or slightly below the line from your eyes. (Having the screen a little further away is usually recommended.)
- Use an external keyboard and mouse, and position them on your desk so that your shoulders and upper arms are relaxed, and your forearms are horizontal to the desk.
- Select a chair that is high enough to allow your elbows to be a little above the height of the desk, that supports your body and preferably does not have armrests. To allow your feet to rest comfortably and horizontally to the floor, you may need a foot rest or a book stack.
- Apply the same safety guidelines that you would normally use with a conventional computer. This means taking regular breaks, using keyboard shortcuts to reduce mousing, attending to good posture and ensuring your body is relaxed, warm and comfortable during computing. See Keyboard Shortcuts and Your Mouse Can Be a Real Pain for tips on these.
2. Carry your laptop in a backpack:
- Get a good bag with padded shoulder straps to carry your laptop. Laptops can be surprisingly heavy so don't strain your arms by carrying the laptop by its handle.
