Previous research tells us that thumb interaction usually has high accuracy and good efficiency when users try to tap the icons within the central area of the display using their thumbs, but low speed and long movement time for the icons at the corner. And touch position on the display are systematically skewed (Henze. N et al. 2011).

The solution we propose is instead of using a perpendicular icon layout, we consider the angular position of each icon, and therefore the layout can be inclined. This brand new touch interface should provide a much more ergonomic solution for one-handed thumb interaction.

Furthermore, instead of a fixed size for all the icons on a phone, this new interface can capture the size of contact areas for different users and customize the icon size for them. And because of the symmetrical nature of this interface, both left-handed type and right-handed type has been integrated into the system.
