For example, when the smart host 20 is stacked on the bottom chassis 10, the angle between the smart host 20 and the bottom chassis 10 is 0 °, and when the smart host 20 is rotated, the angle between the smart host 20 and the bottom chassis 10 may preferably be 90 °. As shown in fig. 1, when the angle between the smart host 20 and the bottom bracket 10 is 0 °, the included angle between the first shooting module 22 and the second shooting module 23 on the smart host 20 relative to the bottom bracket 10 is also 0 °, and at this time, the shooting direction of the first shooting module 22 is upward, and the shooting direction of the second shooting module 23 is downward and is blocked by the bottom bracket 10; as shown in fig. 2, when the smart host 20 rotates relative to the bottom bracket 10 to form a 90 ° included angle, the included angle between the first shooting module 22 and the second shooting module 23 of the smart host 20 relative to the bottom bracket 10 is a 90 ° included angle, the shooting direction of the first shooting module 22 faces left, and the shooting direction of the second shooting module 23 faces right, so that the adjustment of the shooting directions of the first shooting module 22 and the second shooting module 23 can be realized.

Specifically, in order to avoid affecting the shooting angles of the first shooting module 22 and the second shooting module 23, the first shooting module 22 may be preferably provided on an end top side (belonging to a portion of the top side 20 a) of the free end 20d, and the second shooting module 23 may be preferably provided on an end bottom side (belonging to a portion of the bottom side 20 b) of the free end 20 d.

In an embodiment of the present invention, the bottom bracket 10 may have a plate-shaped structure. When the bottom bracket 10 is a plate-shaped structure, the material of the bottom bracket 10 may preferably be a heat insulating material, such as plastic. When the user wears the wearable device, the situation that the heat generation amount of the smart host 20 is large and the wrist skin of the user is possibly scalded can be avoided. Therefore, the bottom bracket 10 not only can realize the function of bearing the rotation of the smart host 20, but also can realize the effect of insulating the smart host 20 from the wrist skin of the user.

Referring to fig. 4, fig. 4 is a flowchart illustrating a video call method according to an embodiment of the present invention. The video call method described in fig. 4 can be applied to the wearable device described in the foregoing embodiment. As described in the foregoing embodiments, the wearable device includes the smart host movably disposed, and the smart host is provided with two photographing modules having different photographing directions, so that when the photographing direction of one photographing module (e.g., the first photographing module 22) disposed in the smart host faces the face of the wearer, the photographing direction of the other photographing module (e.g., the second photographing module 23) disposed in the smart host faces the front environment of the wearer. As shown in fig. 4, the video call method may include the steps of:

wherein, the partial interval between the first time interval and the second time interval is overlapped; or the first time interval comprises a second time interval; or the second time interval comprises the first time interval; the first time interval and the second time interval do not have any interval coincidence.

By implementing the optional implementation mode, the video frame corresponding to the face of the wearer and the video frame corresponding to the front environment of the wearer, which are acquired by the intelligent host, may be video frames in the same time interval or video frames in different time intervals. In addition, when the video frames are video frames in different time intervals, the relationship between the first time interval in which the video frame corresponding to the face of the wearer is located and the second time interval in which the video frame corresponding to the front environment of the wearer is located may be an intersection relationship, an inclusion relationship, and a separation relationship. The process can acquire the video frame corresponding to the face and the video frame corresponding to the front environment of the wearer under the condition of various time intervals, and various use requirements of the wearer of the wearable device are met. For example, when a wearer of the wearable device uses the wearable device to perform a video call, a video frame corresponding to a human face may be selectively displayed for a certain time period (i.e., a time interval), and a video frame corresponding to a front environment may be selectively displayed for another time period.
