Methods and apparatuses for form operation on a mobile terminal
Apparatuses and methods are disclosed for form operation on a mobile terminal. An exemplary method may include detecting an input hand gesture on a screen, and acquiring a trajectory of the input hand gesture. The method may also include matching the acquired trajectory of the input hand gesture with the hand gestures in correspondence in accordance with the hand-gesture comparison rules. The correspondence between hand gestures, hand-gesture comparison rules, and form operations is preset. The method may further include triggering a corresponding form operation if the matching is successful.
