A 3D holographic virtual object display controlling method and apparatus based on human-eye tracking are provided. The display controlling method comprises the following steps of: activating tracking of human eyes of a user; tracking motions of eyeballs of the user; controlling a 3D holographic virtual object presented in a display interface to rotate in response to the motions of the eyeballs of the user; and ending up the tracking of the human eyes of the user. Thereby, the present disclosure can control rotation of a 3D holographic virtual object presented in a display interface by tracking eyeballs and in response to the motions of the eyeballs, which makes the operations convenient and easy.
