It is almost certainly accurate to say that we are all very well aware of the ergonomic dangers associated with lengthy computer usage these days. Any individual who isn't content with their awareness of the facts can immediately bring themselves up to speed-- the varying risks are well documented and widely available.

The rapid growth in the usage of touch screen appliances, tablet computers certainly, but also smartphones and e-readers, poses a possible problem for many users. In fact, for quite a few users, a "mobile" device with a touch screen may actually be their most frequently used computing device.

The continuous use of such devices is a fairly recent trend, and an aspect of the problem is that health experts and ergonomic specialists just haven't had sufficient time to fully scrutinize how users interact with these devices. Documentation is being produced, but there is considerably less info obtainable than for desktop and notebook computers.

Nonetheless, some preliminary worries have already been detected and some informed propositions for the risk-free use of mobile touch screen devices is starting to become available.

And quite possibly at the risk of stating the obvious, keeping good posture any time you are operating a tablet computer or a smartphone is every bit as important as it is when using a desktop or a laptop computer. This requires a little discipline to be exerted by the user.

When working with a desktop or laptop, we normally sit at a workstation or desk and use a mouse and keyboard to enter data. To a degree, correct posture can be promoted by making using of suitable chairs, desks etc. and ensuring that the various items of furniture are at the proper relative distances and heights from each other.

Clearly, with a tablet computer there is a great deal more personal freedom-- which is, to a large extent, a big aspect of their allure. The obligation is absolutely on the user to maintain proper posture and maintain an ergonomically efficient viewing angle.

One other problem which has been determined is the use of those delightful touch screens that we all cherish so much. They are without a doubt incredibly useful, particularly whenever you're on the go. However, compared with an "old fashioned" QWERTY keyboard, virtual keyboards supply no affirmative feedback in the form of a keystroke.

You only receive confirmation that you've achieved your goal when the character that you typed displays upon the display. This can lead to users pressing virtual keys a lot more firmly than they would press the keys on a physical keyboard. Several studies suggest that users may exert as much as eight times as much pressure on a virtual keyboard than would be employed on a physical one.

That can trigger problems like Carpal tunnel syndrome and other types of stress related issues. It may not be a concern for users who only enter text occasionally-- but with a lot of users now using tablet computers as their main device, it could well be concerning for some. An external Bluetooth keyboard might be a worthwhile addition for you if you find that you are entering a great deal of text on your touch screen.

Further health and ergonomic research studies are evolving, and additional suggestions will certainly be forthcoming in the near future. For the time being, tablet computer users would be well advised to make a conscious to maintain good posture and refrain from lengthy periods of text input on their touch screens if at all possible.
