Improving Two-Thumb Text Entry on Touchscreen Devices

[spacial]

KALQ is a split keyboard for touchscreen devices. The position of the keyboard on the display and the assignment of letters to keyslots were informed by a series of studies conducted with the aim of maximizing typing performance. KALQ is used by gripping the device from its corners. Trained users achieved an entry rate of 37 wpm (5% error rate). This is an improvement of 34% over their baseline performance with a standard touch-QWERTY system. This rate is the highest ever reported for two-thumb typing on a touchscreen device. The following factors are exploited in the design of KALQ:
