“…In Young and colleagues' study, they suggested preferred tilt angle most likely changes depending on location of the tablet angle and corresponds to tilt angles that allows for near perpendicular viewing angles, which optimizes luminance and reduces perspective distortion of the display. Our results also correspond to the finding of a previous study that preferences for tablet tilt angles may vary across tasks [13].…”

“…Participants performed all the tasks while seated in a chair with a seat pan height of 44.7 cm, a backrest, and no arm rests. The tablet computer was positioned on a table with a height of 75.3 cm, based on a previous study suggesting that most users preferred to use tablet computers at a table for most tasks [13]. In addition, the chair, desk, and tablet were all positioned to minimize glare on the tablet screen.…”

Abstract. BACKGROUND:Tablet users may be at high risk of developing physical discomfort because of their usage behaviors and tablet design. OBJECTIVE: Investigate the usage of tablets, variations in head and neck posture associated with different tablet tilt angles, and the association of tablet use with users' musculoskeletal discomfort. METHODS: A survey of users' subjective perceptions conducted by questionnaire and measurements of users' postures by a 3D Motion analysis system was used to explore the effects of tablet use. RESULTS:The questionnaire results indicated that over half of the participants reported physical discomfort after using tablets, with the most prevalent discomfort in the neck and shoulders, and more intensity of discomfort for the back although only few participants experienced it. Chi-squared tests indicated that significantly more participants who tended to use tablet computers to play games reported having musculoskeletal discomfort after using a tablet. In addition, preferences for tablet tilt angles varied across tasks (reading and game playing). The results from the 3D motion analysis revealed that head and neck flexion angles were significantly reduced when the tablets were positioned at relatively steep tilt angles. Neck flexion angle was significantly higher in game playing. CONCLUSIONS: These data add information regarding to the usage of tablet and its associations with physical discomfort (significantly more participants who tended to use tablet computers to play games reported having musculoskeletal discomfort after using a tablet). Steep tilt angles (such as 60• ) may cause tablet users to decrease their head and neck flexion angles, which could lead to a more neutral, effortless, and ergonomically correct posture. Maintaining proper neck posture during active activities such as game playing is recommended to avoid neck discomfort.

“…Among three devices, when touch screen is utilized, neck, trunk and arm get more deviation from neutral posture. This is in line with the results of other studies [1,5,9,[25][26][27][28]. The arm is extended significantly more in so as to perform tasks in the touch screen device.…”

“…For example, students could use touchscreen devices when walking around during a lab course, or when collaborating with a partner during a lecture -each context resulting in different range of hand orientation preferences. [6] Different design features (sliders, check boxes, dragging, etc.) and feature locations (top/bottom, left/right) provide opportunities to impact preferred hand orientations during use.…”

During use of touch-screen tablet devices, the user's hand can occlude regions of the screen. Here, we present results from an exploratory study of hand orientation and occlusion among American primary school students using a touch-screen tablet device. We investigated hand orientations, amount of occlusion, and the effects of tablet tilt angle (flat or tilted) on students preferred hand orientations when using a touch-screen tablet device. From 18 interviews with 5th-7th grade students using interactive science simulations, we found five common hand orientations corresponding to a range from high to low occlusion. Tablet tilt angle considerably impacted students preferred hand orientations. Based on these results, we suggest that encouraging students to work on tablets with a moderate tilt angle (30-45 degrees), rather than lying flat on a table, could significantly decrease occlusion and increase the effectiveness of touchscreen tablet devices for learning.
