and after a second target duration, stopping playing the target video and continuing to play the video to be played.
The third preset time period may be, for example, 15min, 17min, 20min, or another value.
Wherein, the stop playing instruction is triggered by a power key of the wearable device. For example, the user continuously clicks the power key 3 times.
The target video may be a video stored in the naked eye 3D display device, or may be a video searched by the naked eye 3D display device from a network, which is not limited herein.
It can be seen that, in the embodiment of the application, if the user pauses playing the video in the motion process, which indicates that the user needs to have a rest for a period of time at present, the naked-eye 3D display device automatically plays the video for relaxing the body and mind, so that the experience of the user using the device can be improved, and the performance of the naked-eye 3D display device is improved.
Optionally, before the playing the target video, the method further includes:
acquiring a video playing record of a non-working time period in a target time period, wherein the termination time of the target time period is the current time;
analyzing the video playing record to obtain K video themes, wherein K is an integer larger than 1;
m video themes are selected from the K video themes, and the M video themes are video themes for relaxing the body and mind;

determining a target video theme according to the M playing frequencies, wherein the playing frequency of the target video theme is the highest playing frequency in the M playing frequencies;
and acquiring the video of the target video theme to obtain the target video.
Among them, the video subjects of relaxing the body and mind are, for example, delicateness, fun, talk show.
Wherein the non-working time period is, for example, 7:00pm to 12:00 pm.
It can be seen that in the embodiment of the application, the target video is determined according to the video playing record in the non-working period, so that the purpose that a proper video is selected according to the actual situation to relax the body and mind is achieved, the experience of a user using equipment is improved, and the performance of a naked eye 3D display device is improved.
Optionally, the second target duration is determined according to the played duration.
Optionally, if the played time length is less than a fourth preset time length, the second target time length is a third set time length, and the third time length is a time length of each body building rest set by the user;
if the played time length is greater than or equal to the fourth preset time length, the second target time length is determined based on the played time length, the third preset time length and the fourth preset time length.
Optionally, the second target duration is determined according to the played duration, the third set duration, the fourth preset duration and a third calculation formula;
wherein the third calculation formula is: t isn＝T5+(T6+T7) xK, wherein, T isnFor the duration to be determined, T5A length of rest per exercise set for the user, T6For the played duration, T7For a preset duration, K is a fixed value, and K is a positive number less than 1, and K is greater than 1/T5。
For example, if the rest time of each exercise set by the user is 1min, the played time is 20min, the fourth preset time is 10min, and K is 0.15, the second target time is 2.5 min.
It can be seen that, in the embodiment of the application, the time length of the user needing rest in the middle of body building is comprehensively determined through a plurality of parameters, so that the accuracy of determining the second target time length is improved.
In an implementation manner of the present application, after the video to be played is played in the 2D display mode, the method further includes:
sending a second user state acquisition request to the wearable device;
