Continuing in this embodiment, in the step S19, when the sit-up posture is not standard, the smart futon alerts the user to perform posture correction. Specifically, the intelligent futon 1 may inherit the intelligent voice system, for example, the user may be prompted to correct the posture through voice prompt of the intelligent voice system, or the intelligent futon may further have a vibration device, and when the posture of the user is incorrect, the user may be prompted through slight vibration, so that the user may correct the posture. The above-mentioned method for reminding the user to correct the posture is only an example, and other existing or future intelligent futons are also included in the scope of the present application, and are included herein by reference.
Preferably, wherein the step S19 includes: the intelligent futon 1 sends the user sitting posture information to the projection equipment 2, so that the projection equipment 2 generates second scene image information based on the user sitting posture, and prompts the user that the current sitting posture is not standard through the second scene image information.
In this embodiment, when the sitting posture of the user is not standard, the user may be prompted by the projection device 2, for example, the user may be prompted by generating second scene image information, where the second scene image information may be preset image information that specifically prompts the user, or may also be image information that is about the sitting posture of the user after being standard, and here, the second scene image information is not limited.
Preferably, wherein the method further comprises: s20 (not shown) the projecting device 2 detects a sitting posture of the user based on the sitting image information; s21 (not shown), when the sitting posture is not standard, the projection device 2 reminds the user of posture correction.
In this embodiment, the sitting posture projection information includes the self-portrait of the sitting person, that is, the projection device may also throw the self-portrait of the sitting person into the projection device when performing virtual projection. In the step S20, the projection apparatus 2 detects the sitting posture of the user, and specifically, the projection apparatus 2 may determine whether the sitting posture of the user is standard by detecting whether the sitting posture projection information of the user is in a state of left-right symmetry, that is, by detecting whether the self-shadow of the user is in a state of standing upright.
Continuing in this embodiment, in step S21, when the sitting posture is not standard, the projection device 2 reminds the user of posture correction.
Specifically, the manner in which the projection device 2 reminds the user to correct the posture may be directly reminded by voice or reminded by the offset of a specific object projected in the scene. Preferably, wherein the step S21 includes: and generating second scene image information based on the sitting image information of the user, and prompting the user to correct the posture through the second scene image information. The second scene image information is used to prompt the user, and may be additional projection information or projection information obtained by changing the current projection information.
For example, when the projected image includes a candle flame, when the user's posture is deviated to the left, the projected candle flame may be inclined to the left all the time, and when the user holds a sitting posture, the flame may be straight, and for example, the projected image includes a crystal ball and the crystal ball includes a standing portrait, when the user's posture is inaccurate, the projected portrait in the crystal ball may be inclined, and the like, or the warning may be given by the direction strength of the scene sound effect surround sound, for example, when the user's sitting posture is deviated to the left, the left sound of the surround sound may be amplified, and the like.
