DragKeys

Miso Kim, Hyeonjoong Cho, Kyeongeun Seo

Most of the watches which are commercially available, for example, Galaxy Gear, Omate, etc., have around 1.5-inch touchscreens that is too small for the shrinked Qwerty keyboard. Moreover, the virtual button-based techniques determine input-letters by distinguishing touched locations on touchscreens which continuously demands a user to carefully touch certain locations.Thus, they are not suitable to tiny-touchscreen devices in mobile environment.Instead, DragKeys allows a user to touch almost anywhere on the touchscreen for text entry by determining input-letters based on drag direction regardless of touched location.

The common soft keyboard on touchscreens for numerous emerging smart devices requires users to look repeatedly at their fingertip locations. To reduce this visual dependency on size-restricted touchscreens, chorded keyboards have been restudied recently. However, one of their intrinsic problems, learning difficulty, limits their widespread use. Here, we introduce a visual guide that makes a chorded keyboard self-revealing to alleviate the learning difficulty. (2014)
