Keypad-based character input in existing digital calculator applications on touch screen devices requires precise, targeted key presses that are time-consuming and error-prone for many screen reader users. We demonstrate GestureCalc, a digital calculator that uses target-free gestures for arithmetic tasks. It allows eyes-free target-less input of digits and operations through taps and directional swipes with one to three fingers, guided by minimal audio feedback. A study of the effectiveness of GestureCalc for screen reader users appears in a full paper by the authors at this conference. [ABSTRACT FROM AUTHOR] |
