A projection display method and device, the method comprising the following steps: receiving an audio signal transmitted by a projection presenter, and parsing the audio signal into character information; searching a target object corresponding to the character information; when the target object corresponding to the character information is found from a current projection playing interface, modifying a display parameter of the target object, such that the target object is switched from a preset first display state to a preset second display state. The device comprises an audio signal receiving module, an audio signal parsing module, a target object search module and a first display state change module. The technical solution can help an observer position a current playing progress quickly, while facilitating a projection presenter to present his own lecture progress in a lecture process. |
