“…A number of studies have quantitatively measured postural variations during tablet usage and compared the results with desktop and/or laptop usage [4,5]. Compared with desktop computer usage, tablet usage is associated with more flexed and asymmetrical spinal postures, more flexed and elevated shoulders, and greater muscle activity around the neck [6][7][8].…”

Abstract. The number of people using online tablets in public places has increased dramatically. Their postures are dominantly characterized by nonneutral and awkward positions that in the long term may lead to a higher risk of musculoskeletal disorders. The purpose of this study was to investigate the effects of tablet compared to laptop (i.e. netbook) usage postures on the development of fatigue, discomfort and pain. A total of 12 participants accomplished email typing tasks for 2 hours with four different usage configurations: 1) Netbook-on-table, 2) Netbook-on-lap, 3) Tablet-on-table, and 4) Tablet-on-lap. Changes in fatigue, discomfort, and pain were monitored based on pinch grip strength (tip pinch, key pinch, and palmar pinch), rating of perceived discomfort, and Phalen's & Reverse Phalen's tests, respectively. The results indicated that the effect of portable device placement was significant (p < 0.05), with varied effects across measurements. No effect of portable computer type was found. The interactive effect of portable computer type and placement was only significant for right tip pinch (p < 0.05). The findings of this study can hopefully be used to increase the awareness of tablet users about associated fatigue, discomfort and pain while using a tablet in public places that may lead to a higher risk of musculoskeletal disorders.

“…Gold i saradnici (Gold, Driban, Yingling, & Komaroff, 2012) pokazali su da korisnici govore o većem diskomforu kad laptop koriste u ležećoj poziciji nego kad sede. Pored specifičnog dizajna, razlog za zauzimanje neuobičajenih položaja prilikom rada jeste mobilnost laptopa.…”

“…Kako bi se interakcija sa uređajem učinila efikasnijom (poboljšanje vidnog polja, brži unos komandi), dolazi do zauzimanja neuobičajenih položaja, a kao posledica javlja se diskomfor. Ovo istraživanje potvrdilo je nalaze istraživanja u kojima se razmatraju implikacije dizajna desktop i laptop računara, pri čemu su mobilnost i integrisanost laptop uređaja razlozi zbog kojih se interakcija korisnika ova dva tipa uređaja razlikuje (Asundi et al, 2010;Demmans et al, 2007;Erdinc, 2011;Gold et al 2012;Price & Dowell, 1998;Straker et al 1997;Szeto & Lee, 2002).…”

“…Seated postures with sufficient back support are often more comfortable than the prone, with relaxed shoulders and more neutral postures. While the postures varied across these various configurations, once in a specific configuration there is very little variability in posture [22].…”

“…Findings in one study indicate that 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 [21]. In addition to placing the notebook in the lap, notebook users take on many other non-desk postures [22]. These include sitting cross-legged, laying prone (face down), and seated with feet raised and legs either straight or knees flexed approximately 90 • .…”

Abstract. BACKGROUND:Because mobile computing technologies, such as notebook computers, smart mobile phones, and tablet computers afford users many different configurations through their intended mobility, there is concern about their effects on musculoskeletal pain and a need for usage recommendations. OBJECTIVE: Therefore the main goal of this paper to determine which best practices surrounding the use of mobile computing devices can be gleaned from current field and laboratory studies of mobile computing devices. METHODS: An expert review was completed. RESULTS: Field studies have documented various user configurations, which often include non-neutral postures, that users adopt when using mobile technology, along with some evidence suggesting that longer duration of use is associated with more discomfort. It is therefore prudent for users to take advantage of their mobility and not get stuck in any given posture for too long. The use of accessories such as appropriate cases or riser stands, as well as external keyboards and pointing devices, can also improve postures and comfort. CONCLUSIONS: Overall, the state of ergonomics for mobile technology is a work in progress and there are more research questions to be addressed.
