Abstract
The disclosure provides a method for controlling a projection content and an electronic device. The method includes: controlling a projector to project a display content on a projection plane; obtaining a display range of the display content on the projection plane; detecting a light spot on the projection plane; and adjusting the display content based on a movement condition of the light spot with respect to the display range.
Claims16
A method for controlling a projection content adapted for an electronic device, the method comprising:
- controlling a projector to project a display content on a projection plane;
- obtaining a display range of the display content on the projection plane;
- detecting a light spot on the projection plane, wherein the light spot is emitted by an indicator device to the projection plane, and the indicator device is paired with the electronic device;
- and
- adjusting the display content based on a movement condition of the light spot with respect to the display range, comprising:
- in response to determining that the light spot is located in the display range and that a first triggering operation occurs on the indicator device, obtaining a light spot movement trace of the light spot in the display range;
- and
- displaying an indicator movement trace in the display content, wherein relative positions of the indicator movement trace and the display content correspond to relative positions of the light spot movement trace and the display range.
(canceled)
An electronic device associated with an indicator device, comprising:
- a light spot detection circuit;
- a non-transitory storage circuit for storing a plurality of modules;
- and
- a processor coupled to the storage circuit and accessing the plurality of modules to perform following steps:
- controlling a projector to project a display content on a projection plane;
- obtaining a display range of the display content on the projection plane;
- detecting, with the light spot detection circuit, a light spot on the projection plane, wherein the light spot is emitted by an indicator device to the projection plane, and the indicator device is paired with the electronic device;
- and
- adjusting the display content based on a movement condition of the light spot with respect to the display range, comprising:
- in response to determining that the light spot is located in the display range and that a first triggering operation occurs on the indicator device, obtaining a light spot movement trace of the light spot in the display range;
- and
- displaying an indicator movement trace in the display content, wherein relative positions of the indicator movement trace and the display content correspond to relative positions of the light spot movement trace and the display range.
