A method and a device for interaction of data objects in a virtual reality/augmented reality spatial environment are provided. The method for interaction of data objects in virtual reality can provide a virtual store spatial environment. A user can experience a 3D spatial environment and realize a specific interaction process via voice. For the user, only speech is needed for interaction, a manual input device such as an external joystick is not needed. Most importantly, in terms of payment, a manual payment process is not required, and payment legitimacy is determined by a user's voiceprint features, determining whether to process a payment and ensuring secure user payment in a virtual store scenario. On the basis that the technical solution realized by augmented reality adopts similar technical concepts, the same technical effect can be achieved.
