“…First, it can be utilized to improve the quality of interaction with a smartphone QWERTY soft keyboard in terms of user experience. Smartphone QWERTY soft keyboards typically have the inherent design challenge of placing a large number of keys in a small space, and thus, there has been a constant need to improve usability, especially in terms of typing speed and accuracy [14][15][16][17][18]. In this context, obviously, the study on the thumb choice patterns for keystrokes and their causes is expected to not only directly and indirectly help improve the design of the QWERTY soft keyboard for better usability but also increase user satisfaction.…”

This study aims to observe which thumb, the left or right, is used for keystrokes and examine the patterns during two-thumb key entry on a smartphone QWERTY soft keyboard. A total of 36 college students, including 18 left-handed and 18 right-handed, were recruited for testing, and they had 9.7 years of smartphone use experience on average. A smartphone application was implemented, and whether the left or right thumb was used for touch interactions was recorded for each of the 26 letter keys. As a result, it was found that there were slightly more letter keys that were statistically more often tapped by the left thumb during the two-thumb key entry on the QWERTY soft keyboard, regardless of the participant’s handedness. In addition, all the letter keys were touched statistically more often with the relatively closer one of both thumbs, except for the letter keys G and V in the center. It seemed that the distance between keys and thumbs was regarded as the most important factor influencing the thumb choice for keystrokes, followed by the habituated experience of using physical QWERTY keyboards.

“…Despite rapid changes in smartphone technologies, a QWERTY layout is still considered to be an important method of text entry on smartphones. A QWERTY soft keyboard is the most fundamental tool for text entry provided by most smartphones available in the global market [1,2], and simultaneously, it is regarded as the most popular layout of soft keyboards among smartphone users [3,4]. In general, smartphone users may prefer the QWERTY layout, as their previous experience with a personal computer can be applied to texting on a smartphone [5,6].…”

“…They confirmed that the keys that were located farther from the thumbs' initial positions required more cognitive effort as well as elongated the travel time of the thumbs to reach the keys, resulting in greater user-discomfort. On the other hand, Ashaduzzaman et al [13] and Pritom et al [3] analyzed the variation in touch performance as a function of different shapes and layouts of keys on a soft keyboard. They showed some evidence that the speed and accuracy of text entry could be improved when the shapes and layouts of keys on a soft keyboard were modified.…”

This research aims to examine touch performance and user-satisfaction depending on key location in a QWERTY soft keyboard during two-thumb key entry on a smartphone. Thirty-three college students who were smartphone users were recruited, and an experimental program was implemented to measure their task completion time, the number of touch errors, and user-satisfaction during key entry. The QWERTY layout was split into 15 zones to assign absolute positions for reliable statistical analysis. The results showed that the zones with significantly longer task completion times were observed more prevalently in the zones in the periphery (p < 0.0001). In addition, relatively higher subjective satisfaction ratings were found in the zones in the center area of the QWERTY layout (p < 0.0001). It seemed that both of the results were improved in the zones that participants could immediately see without moving the thumbs, before touch interaction. Meanwhile, touch error frequencies failed to show statistical significance among the zones (p = 0.3195).
