Abstract: A method and a system for remote sharing annotation trajectory in a three-dimensional space are provided. In response to activating a first electronic apparatus to display a first space, the first electronic apparatus obtains a first reference point of a designated object presented in the first space. After the first electronic apparatus displays the first space, the first electronic apparatus detects a three-dimensional movement trajectory of a target object in the first space, detects inflection point information of the three-dimensional movement trajectory and captures a diameter of the three-dimensional movement trajectory, and then sends the inflection point information and the diameter to a second electronic apparatus. In response to activating the second electronic apparatus to display a second space, the second electronic apparatus reconstructs the three-dimensional movement trajectory based on the inflection point information and the diameter, and presents the three-dimensional movement trajectory in the second space based on a second reference point relative to the first reference point.
