Swype Keyboard

An alternative to the Android virtual keyboard, the Swype virtual keyboard allows you to input text by swiping the finger with one continuous finger or stylus motion across the screen keyboard. Based on testing, speed, and accuracy are equal to or better than the traditional keyboard-tapping method. You can activate the Swype keyboard by pressing and holding in a text field, wait for popup to appear, click Input Method, and then select Swype.

In the image to the left, the word “mind” was generated from tracing the path shown to the right in a fraction of a second, by roughly aiming to pass through the letters of the word. A key advantage to Swype is that there is no need to be very accurate, enabling very rapid text entry.
