“…Especially, using tablet computers leads to degraded wrist and neck postures, which may increase risk for injury or illness development for these parts of the body. Pereira et al (2013) evaluated the effect of tablet size, orientation, grip shape, texture and stylus shape on productivity, biomechanics, and subjective usability and fatigue associated with holding the tablet with just left hand. This study confined its examinations among users with small hands, because subjects with smaller fingers are likely to be exposed to higher risk of using handheld devices.…”

“…Although not directly related with tablet PC use by children, the work of Pereira et al (2013), which considered tablet design features on biomechanics among users with small hands, should also be mentioned here. Because, although the overall hand size of subjects was still bigger than the hand size of children, the study results can give an idea on children's use of same technology.…”

Educational ergonomics focuses on the interaction between educational performance and educational design. By improving the design or pointing out the possible problems, educational ergonomics can be utilized to have positive impacts on the student performance and thus on education process. Laptops and tablet computers are becoming widely used by school children and beginning to be used effectively for educational purposes. As the latest generation of laptops and tablet computers are mobile and lightweight compared to conventional personal computers, they support student-centred interaction-based learning. However, these technologies have been introduced into schools with minimal adaptations to furniture or attention to ergonomics. There are increasing reports of an association between increased musculoskeletal (MSK) problems in children and use of such technologies. Although children are among the users of laptops and tablet computers both in their everyday lives and at schools, the literature investigating MSK activities and possible MSK discomfort regarding children using portable technologies is limited. This study reviews the literature to identify published studies that investigated posture, MSK activities, and possible MSK discomfort among children using mobile technologies (laptops or tablet computers) for educational purposes. An electronic search of the literature published in English between January 1994 and January 2014 was performed in several databases. The literature search terms were identified and combined to search the databases. The search results that the resources investigating MSK outcomes of laptop or tablet use of children are very scarce. This review points out the research gaps in this field, and identifying areas for future studies.

“…Pereira et al [50] examined various tablet form factors while holding the tablet with the left hand only. When used while standing, for example during walk through inspections of construction sites or entering data into an electronic medical record system in a patient's room, it is expected that the device will be held with the left hand only.…”

“…When used while standing, for example during walk through inspections of construction sites or entering data into an electronic medical record system in a patient's room, it is expected that the device will be held with the left hand only. For this configuration, Pereira et al concluded that smaller to medium size tablets are better in terms of usability, comfort, fatigue, and biomechanics [50].…”

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.

“…Findings of previous works revealed that increasing size of smartphone display make people feel tired because of bad grip comfort (Kietrys et al, 2015;Pereira et al, 2013). Furthermore, usability of smartphone is also deteriorated because of smartphone size (Xiong & Muraki, 2016).…”

The aim of the study is to test the effects of smartphone width on touch performances in order to investigate the appropriate size of smartphone for one-handed interaction. We used four different width level for the experiment, which were 67mm, 70mm, 72mm, and 74mm. Participants were asked to perform tapping task. We measured two touch performances, success rate and task completion time. The success rate of 67mm device was higher than that of other devices. We confirmed that this results come from the poor performances at marginal screen area. However, task completion time of 67mm device was unexpectedly poor than that of other devices.
