One Line Soft Keyboard with T9-keys Layout Proposal on Smartwatch Touch Screen Device

A smartwatch is a mini-sized digital computer device that functions apart from being a watch and can also perform intelligent computing tasks. Due to screen size limitations, a smartwatch requires special design techniques on its input and output to allow interaction with its users. Text entry is often required by many applications, but because the smartwatch screen is small, text entry techniques commonly used on personal computers are impractical when applied to smartwatches. In this study, we introduce a design concept proposal for a soft keyboard called One Line Soft Keyboard with T9-Keys Layout. The soft keyboard design concept is expected to reduce the space on the keyboard on the smartwatch screen, along with the use of widely used button layouts that are familiar to users.
