“…In this posture, the surface area under the thumb was greater given its flat orientation relative to the phone's surface. Park and Han (2010b) hypothesize that a larger surface area of the thumb might be related to poor target selection accuracy, which is consistent with the larger effective target widths (i.e., poorer precision) measured in this study for the middle of the phone compared to keys on the left and right edges. Table 3 Average (and standard devation) values for the distance between the CMC joint 3D position and the key being tapped (mm) at the instant when the thumb tip contacted the key, for each key.…”

“…While these have been studied in the past (e.g., [3,20,21,9]), the studies have considered a single surface type at a time, such as tabletops [14], vertical displays [24], tilted displays [13], or handheld devices [20]. It has been impossible to form an overview of how the surface types differ in interaction.…”

Figure 1. This paper presents performance and ergonomics indices for six typical touchscreen surfaces. Motion capture-based biomechanical simulation was used to understand differences in speed, accuracy, posture, energy expenditure, and muscle group differences. This figure shows the median postures recorded in the study. ABSTRACTAlthough different types of touch surfaces have gained extensive attention in HCI, this is the first work to directly compare them for two critical factors: performance and ergonomics. Our data come from a pointing task (N=40) carried out on five common touch surface types: public display (large, vertical, standing), tabletop (large, horizontal, seated), laptop (medium, adjustably tilted, seated), tablet (seated, in hand), and smartphone (single-and two-handed input). Ergonomics indices were calculated from biomechanical simulations of motion capture data combined with recordings of external forces. We provide an extensive dataset for researchers and report the first analyses of similarities and differences that are attributable to the different postures and movement ranges.

“…A few studies looked into designs for thumb-based interaction and found that there were four factors that impacted accuracy of thumb-based interaction: the size of the key, key location, thumb length, and user age [100,101]. Similar to index finger interaction, input accuracy of thumb interaction increased as the size of the key increases, and the key must be located within the areas that can be easily reached by a thumb, which were the bottom-left, the center, and the upper-right area [100]. Thumb coverage area was also influenced by users' thumb length and their age.…”

Mobile platforms have called for attention from HCI practitioners, and, ever since 2007, touchscreens have completely changed mobile user interface and interaction design. Some notable differences between mobile devices and desktops include the lack of tactile feedback, ubiquity, limited screen size, small virtual keys, and high demand of visual attention. These differences have caused unprecedented challenges to users. Most of the mobile user interface designs are based on desktop paradigm, but the desktop designs do not fully fit the mobile context. Although mobile devices are becoming an indispensable part of daily lives, true standards for mobile UI design patterns do not exist. This article provides a systematic literature review of the existing studies on mobile UI design patterns. The first objective is to give an overview of recent studies on the mobile designs. The second objective is to provide an analysis on what topics or areas have insufficient information and what factors are concentrated upon. This article will benefit the HCI community in seeing an overview of present works, to shape the future research directions.
