Example 1

Please refer to FIG. 1 and FIG. 2 together, and now the human-computer interaction method provided by the present invention will be described. The human-computer interaction method is applicable to an interactive device for controlling the target item to move to the target area. The interactive device includes a display 1 and a delivery component 2 capable of accommodating the target item. The target item and the target area are respectively in A virtual target item and a virtual target area are mapped on the display 1, and there are multiple areas to be eliminated between the virtual target item and the virtual target area. Specifically, the virtual target item and the virtual target area are directly displayed on the On the display 1, the target item is stored inside the delivery component 2, and the delivery component 2 can move the target item to the target area. In this embodiment, the relationship between the target item and the target area is also mapped on the display 1 as The relationship between the virtual target item and the virtual target area. Specifically, when the virtual target item is moving to the virtual target area, the corresponding target item is linked with the virtual target item to move to the target area, or the virtual target item is moving to the virtual target area. When the target area is reached, the corresponding target item moves to the target area. Among them, the target item is generally an incentive prize, and when it moves to the target area, it is put on the outside of the interactive device for the user to pick up. The delivery component 2 generally includes hardware such as a steering gear, a reducer, and a control circuit, which can control the movement of the target item. Move, collect and distribute.

The method comprises the steps of:

S101. Obtain the preset expression and the user's facial expression in the area to be eliminated respectively; the preset expression is preset in the area to be eliminated, and the user is required to imitate the preset expression and compare the user's imitated facial expression with the preset expression Until the facial expression imitated by the user matches the preset expression. For the preset expression, it can be a preset expression randomly generated after selecting the area to be eliminated, and it can also be a preset expression displayed in the area to be eliminated, that is, the user can select the area to be eliminated according to needs and their own conditions .

S102. Determine whether the matching degree of the user's facial expression and the preset expression in the area to be eliminated is greater than a preset threshold; the preset threshold is generally used to judge the matching degree of the user's facial expression and the preset expression in the area to be eliminated, and the predetermined The set threshold can be adjusted as needed, and when the matching degree is greater than the preset threshold, go to step S103. When the matching degree is less than the preset threshold, return to step S101.

S103. Eliminate the area to be eliminated, and control the virtual target item to move to the virtual target area. After the area to be eliminated is eliminated, the virtual target item judges whether it can move towards the virtual target area. If it can move towards the virtual target area, the virtual target item moves towards the virtual target area. If it cannot move towards the virtual target area, the virtual target item The position is unchanged.

In the human-computer interaction method provided by the present invention, compared with the prior art, in the interactive device, the target items that can be dropped by the delivery component 2 are corresponding to the virtual target items in the display 1, and the virtual target items can be shortened by eliminating the area to be eliminated. The distance between the target item and the virtual target area can then move the virtual target item to the virtual target area, thereby controlling the delivery component 2 to move the target item to the target area. When the elimination area is eliminated, the user's facial expression and preset Set the expression for comparison and eliminate the area to be eliminated according to the matching degree. It is different from the traditional elimination method and can enable the user to have stronger interaction with the interactive device. The target item and the virtual target item are linked to enhance the target item and The interaction between users is more playable and the human-computer interaction is closer.

As an optional embodiment, step S103 may include: after eliminating the area to be eliminated, move the virtual target item to the area to be eliminated, select a new area to be eliminated, and repeat steps S101 and S102 until the virtual target item Move to the virtual target area. In this embodiment, the selection of the new area to be eliminated can be based on a preset path, that is, the area to be eliminated that the virtual target item needs to pass through to move to the virtual target area is set in advance, and only the virtual target item needs to be moved to All the areas to be eliminated on the preset path passed by the virtual target area are eliminated, and the virtual target item can be moved to the virtual target area. As another new way to select the region to be eliminated, the next region to be eliminated can be determined by accepting the user's selection instruction, for example, by acquiring the user's touch event on the display 1, the so-called The touch event may indicate that the user selects an area to be deleted, and the next area to be deleted selected by the user is determined according to the touch event, and steps S101-S102 are repeated until the virtual target item moves to the virtual target area.

As another optional implementation manner, please refer to FIG. 1 and FIG. 2 together. Before acquiring the preset expression in the area to be eliminated, the method may further include: acquiring a start instruction and setting a timing clock according to the start instruction.

Specifically, the judgment of whether the virtual target item reaches the virtual target area is based on judging the distance between the virtual target item and the virtual target area, and the judgment time can be after the virtual target item moves to the virtual target area and after Judgment is made before the end of the timing clock. When the virtual target item moves to the virtual target area, the target item moves to the target area. At this time, the target item can move with the movement of the virtual target item, or the target item moves to Move directly to the target area when virtualizing the target area. At the end of the timing clock, if the virtual target item has not yet arrived at the virtual target area, then the game fails. At this time, the throwing component 2 controls the target item to get back to the initial position, and the target item is reclaimed, and the game returns to the initial state.

The method for judging whether the matching degree between the user's facial expression and the preset expression in the area to be eliminated is greater than the preset threshold is introduced below. As an optional implementation, the method mainly includes the following steps

First, obtain the feature point set of the preset expression; specifically, select specific features from the face of the preset expression, such as eye features, mouth features or cheek features, and form the above features into a feature point set , the feature point set can be determined when the preset expression is preset, or the feature point set can be obtained after a specific preset expression is selected.

Secondly, extract the face feature point set in the user's facial expression; Specifically, the user's facial expression is collected by the image acquisition device 3 and then the user's facial expression collected by the image acquisition device 3 is analyzed, and the facial feature point and the facial feature point are extracted. The facial feature points of the extracted preset expressions are in one-to-one correspondence.

Finally, calculate the matching degree of the feature point set of the described human face and the feature point set of the preset expression, specifically, compare the extracted human face feature point with the facial feature point of the preset expression one by one, and finally The feature point set of the human face is compared with the feature point set of the preset expression, so that a comparison result can be obtained.
