In the embodiment of the present invention, the celestial body name may be a name of any celestial body, and the user of the wearable device may input the celestial body name in a manner of text, voice, or the like.

For example, a screen of the intelligent host can output a text input box, and a user can input a celestial body name to be queried through the text input box; the intelligent host can also collect the sound in the environment where the wearable device is located through a microphone arranged on the intelligent host, and identifies the collected sound, and when the collected sound is detected to contain the voice corresponding to the celestial body name, the celestial body name corresponding to the voice can be determined to be the celestial body name which needs to be inquired and is input by the user; the intelligent host can also output a plurality of celestial body types through the screen so that a user can select a target celestial body type to be checked by clicking any celestial body type in the screen, and then the intelligent host can output one or more celestial body names contained in the target celestial body type so that the user can select a celestial body name to be checked by clicking any celestial body name in the screen. Therefore, the intelligent host can acquire the celestial body name input by the user in different modes, and the use experience of the intelligent host is improved.

In the embodiment of the invention, the current Positioning information of the wearable device can be positioned through a Global Positioning System (Global Positioning System), a Beidou satellite navigation System and the like, and the Positioning information can be longitude and latitude coordinates of the position where the wearable device is located. The spatial state information of the wearable device can be information such as the altitude and the inclination angle of the wearable device, and the spatial state information of the wearable device can be collected through nine sensors arranged on the wearable device. The intelligent host can acquire the position of the target celestial body relative to the earth, namely the relative position information of the target celestial body relative to the earth through the internet.

As an optional implementation manner, before the smart host performsstep 401, the following steps may also be performed:

when an astronomical knowledge learning instruction triggered by a user is detected, the intelligent host outputs a search page through a screen, wherein the search page can contain a character input box, and the character input box can be used for acquiring character information input by the user;

607. And the intelligent host calculates to obtain a target included angle according to the inclination angle and the relative position information.

In the embodiment of the invention, the intelligent host can acquire the third included angle between the target celestial body and the ecliptic surface of the earth from the relative position information of the target celestial body relative to the earth, the intelligent host can also determine the fourth included angle between the intelligent host and the ecliptic surface of the earth according to the inclination angle of the intelligent host, and then the intelligent host can calculate the target included angle between the intelligent host and the target celestial body according to the third included angle and the fourth included angle, so that after the intelligent host adjusts the included angle between the intelligent host and the host bracket to be the target included angle, one side of the intelligent host can be opposite to the target celestial body.
