Mobile devices as laptop, notebook or tablet PC, works at its best on mobility. These technologies are now introduced into the workplace and elsewhere, expecially at home, where an increasing number of users as home-workers, freelance, business people, spend most of time working with computers with health implications associated with overuse.
Due to their mobility notebook computers are used in a variety of work environments resulting in several user postural configurations. Users often sit in chairs and work with notebook computers set on non-adjustable work-surfaces without the use of external keyboards, pointing devices, or monitors.
Don’t hold your laptop on your lap.
Working with notebook computers on the lap is associated with even more head and neck flexion. This can be attributed to the lower screen height of a notebook computer, which has been reported several times as a significant factor for head and neck discomfort. In addition to placing the notebook in the lap, notebook users take on many other non-desk postures. These include sitting cross-legged, laying prone (face down), and seated with feet raised and legs either straight or knees flexed approximately 90 degrees.
Accessories can improve non-neutral postures associated with the devices, to setting up a notebook to emulate a desktop computer, with the use of accessories such as notebook riser, keyboards and pointing devices. The use of external keyboards and pointing devices is associated with lower levels of discomfort and better levels of productivity Performance is often better with an external mouse compared to an internal touch pad.
Lounge-book improves head and neck postures and user experiences
Lounge-book is the fully adjustable laptop support that allow to find a good posture using laptop at home.
Height regulation, tilting and rotating laptop base, Lounge-book easly slide under most of furniture as armchair, sofa, chiase longue, lounge-chair, and even bed.
Seated postures with sufficient back support are often more comfortable than the prone, with relaxed shoulders and more neutral postures.
Working with notebook computers on top of a desk has been associated with greater head and neck flexion; however, it is often associated with less wrist extension.
Compared to working with a desktop or a notebook in a desktop configuration (raised monitor and external keyboard and mouse) head flexion is about 10 degrees more when using a notebook computer.
Lounge-book also allow to move legs: sitting in the same position for hours, like in a chair where the body is bent at the hips and knees, can block blood from getting back to the heart, and may even cause your legs to become swollen.
