Two-handed grip on a mobile phone affords greater thumb motor performance, decreased variability, and a more extended thumb posture than a one-handed grip a b s t r a c t Holding a mobile computing device with two hands may affect thumb motor performance, joint postures, and device stability compared to holding the device and tapping the touchscreen with the thumb of the holding hand. It indicates that the two design elements are not a common practice.

The results show that the large-area keyboard is significantly better in terms of pairs per minute and reaction time between two keys, at the same time, the curved keyboard performs worse than the traditional keyboard. large-area: letter key area is 6.3 mm × 9 mm), and 2 keyboard layouts (curved QWERTY vs. 6.5 in.), 2 area sizes (small-area: letter key area is 4.9 mm × 7 mm vs. Following the design of existing curved keyboards, we designed a keyboard application, which could collect all the usage data, to test whether the curved keyboard or reduced-area keyboard could indeed solve the input inefficiency issue. Curved QWERTY keyboard and reduced soft keyboard area are proposed to solve the input inefficiency issue of application design in the large smartphones. However, larger screen brings about unsatisfactory input issue, especially for one-handed users. Smartphone has been constantly optimizing the user experience of viewing content by increasing screen size. The proposed method for the manipulation comfort of the human thumb bridges the gap between the layout planning of soft keyboard of smartphones and the comfort of single thumb manipulation. The proposed quantitative study method of the thumb manipulation comfort is verified by 12 subjects who hold a smartphone with one hand and manipulate the screen with one thumb, and the most comfortable keyboard layout of smartphone is determined for the 12 subjects. Finally, the design problem of the smartphone’s keyboard area is transformed into an optimization problem that determines the most comfortable manipulation space for the human thumb. Then some indexes such as the morphology and volume of the comfort ellipsoid, and the condition number of the thumb Jacobian are presented to evaluate the manipulation comfort of the thumb. In light of the fact that most users tend to hold the smartphone in one hand and manipulate with one thumb in daily life, this paper extracts the thumb kinematic chain from the thumb anatomy of the human hand, and defines the manipulation comfort ellipsoid of the thumb.

Don’t grant full access to a keyboard unless you’re comfortable with that little security caveat.įinally, you can cycle through your keyboards on the fly by tapping the little globe key in the bottom-left corner of the keypad itself.The objective of this paper is to develop a theory for designing the keyboard area of smartphones, and endowing the users with comfortable texting ability via one thumb. Note: Flipping the “Allow Full Access” switch will let the keypad send data about your keystrokes-including anything sensitive you type, like account numbers or passcodes-to the makers of the keypad. Certain third-party keyboards (more on them in a moment) may (with your permission) have full access to your keystrokes, usually so they can better learn your typing habits. For the English keyboard, for example, you can chose between QWERTY, AZERTY, and QWERTZ layouts. See a little arrow to the right of a given keyboard? If so, tap it to reveal some options. Swipe a keyboard in the list from right to left, then tap Delete to nix a keypad, or tap Edit and drag a handle on the right to reorder your keyboards. To manage your list of keypads, go back to the Keyboards screen.
