In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

An embodiment of the present invention provides a control method based on a virtual reality device, as shown in FIG. 1, the method includes:

101. When the virtual reality device plays video data, detect whether a preset trigger tag exists at the current time point according to the time axis corresponding to the video data.

Wherein, the preset trigger tag may include scent identification information, which may be pre-configured according to video content, and the scent identification information may be a scent name, ID (Identity, identification number) number, etc. For example, when there is a segment of a sea of flowers in the video content, a preset trigger tag corresponding to the segment is configured, and the scent identifier corresponding to the preset trigger tag can be a floral scent identifier; when there is a segment of tasting bread in the video content, A preset trigger tag corresponding to the segment is configured, and the scent identifier corresponding to the preset trigger tag may be a bread fragrance identifier.

102. If there is a preset trigger tag at the current time point, send a control command to the smell smart device according to the preset trigger tag.

Further, it is convenient for the smell smart device to emit the smell corresponding to the smell identification information. For the embodiment of the present invention, in order to enable users who experience the virtual reality effect to feel the sense of smell, the smell smart device can be set in the virtual reality device, or around the user who uses the virtual reality device, and can be specifically determined according to the actual situation. needs to be set.

For example, if there is a preset trigger tag at the current time point, and the scent mark corresponding to the preset trigger tag is a floral scent mark, a control instruction is sent to the scent smart device so that the scent smart device emits a floral scent.

According to a control method based on a virtual reality device provided by an embodiment of the present invention, when the virtual reality device plays video data, it detects whether there is a preset trigger tag at the current time point according to the time axis corresponding to the video data. The preset trigger tag contains scent identification information; if it exists, then according to the preset trigger tag, a control instruction is sent to the scent smart device, so that the scent smart device emits a scent corresponding to the scent identification information. Compared with the current experience of the virtual reality effect when the user only has a direct visual experience, the present invention controls the sending of control instructions to the smell smart device according to the preset trigger tag corresponding to the video data, so that the smell smart device sends out a video that matches the currently played video. Content-related smells not only give users a visual experience, but also give users a direct experience of smell, which can enhance the immersion of users in experiencing virtual reality effects.

204b. Send a control instruction to the odor smart device according to the trigger analysis result.

Further, the odor smart device emits an odor corresponding to the trigger analysis result.

For example, when the virtual reality device plays video data, the video content in the trigger parsing result corresponding to the current time point involves a scene that emits a flower fragrance, and a control command is sent to the scent smart device so that the scent smart device emits a flower scent.

For the embodiment of the present invention, the step 204 may specifically include: sending a control instruction to the odor smart device according to the trigger analysis result of the video data within the preset time interval corresponding to the current time point.

It should be noted that, for video data with a lot of video content and a long video time, trigger analysis is performed on the video data in each preset time interval according to the sequence of playback time corresponding to the video data, and the corresponding trigger Analyze the results, and send control instructions to the smell smart device according to the trigger analysis results of the video data within the preset time interval corresponding to the current time point, which can avoid the trigger analysis of the video data for a long time. According to the relevant trigger analysis results, when the video content during this period involves a scene emitting odor, the occurrence of odor emitted by the odor smart device cannot be well controlled.

Further, the method further includes: when receiving an instruction to stop releasing a scent input by a user, sending a control instruction to stop releasing a scent to the smart scent device, so that the smart scent device stops emitting a scent, so as to meet the needs of different users. demand.
