Fix and slide: caret navigation with movable background

We present a concept of using a movable background to navigate a caret on small mobile devices. The standard approach to selecting text on mobile devices is to directly touch the location on the text that a user wants to select. This is problematic because the user's finger hides the area to select. Our concept is to use a movable background to navigate the caret. Users place a caret by tapping on the screen and then move the background by touching and dragging. In this method, the caret is fixed on the screen and the user drags the background text to navigate the caret. We compared our technique with the iPhone's default UI and found that even though participants were using our technique for the first time, average task completion time was not different or even faster than Default UI in the case of the small font size and got a significantly higher usability score than Default UI.
