A method and device for content interaction in virtual reality, for use in addressing the limitations in the prior art that virtual environment control by a person is limited to limb movements or manual instructions and a virtual environment can only passively receive a control instruction from the person to perform interaction feedback. The method comprises: obtaining an electroencephalography signal; parsing the electroencephalography signal to obtain emotion cognition information corresponding to the electroencephalography signal; and performing, according to the emotion cognition information, corresponding content interaction on a virtual environment. Whereby, virtual environment control can be completed by means of an electroencephalography signal directly without limb movements or manual instructions. By analyzing the electroencephalography signal to actively perceive the emotion cognition of a person, a virtual environment can actively perform interaction feedback with the person; in addition, interactive behaviors are not limited to images and touch only, and emotion states, attention states and the like can also be used as interactive means.
