Embodiment one
Referring to figure 2., the embodiment of the present invention one are as follows: a kind of interface interaction method, the method is based on physical engine
Collision detection can be applied to type singing system, such as KTV song-on-demand system, and described method includes following steps:
S1: creating the first display layer and the second display layer on the screen, and first display layer and the second display layer are from upper
Under transparency overlay on the screen.Coordinate system can be established in first display layer, and by the back of first display layer
Scape is rendered into transparent background.Further, the screen can show the video pictures of current requesting songs.
S2: camera picture or preset video flowing are obtained, and the camera picture or video flowing real-time display are existed
On second display layer.Wherein, camera can be the camera of the mobile terminal communicated to connect with song-order machine, or
The included camera of the set-top box of song-order machine, including IP Camera, USB camera.Video flowing can be shot in advance for user
Video, or the video clip downloaded from network.
S3: the camera picture or view are obtained by face critical point detection algorithm and human body attitude detection algorithm in real time
The key point position of face and human body, i.e., the video frame in picture frame or video flowing camera shot in real time in frequency stream
The detection of face key and human body attitude detection are carried out, key point position is exported.Wherein, key point position includes face key point
It sets, such as eyes, nose, mouth, ear, further includes human body key point position, such as head, shoulder, hand.Face critical point detection
Algorithm can choose current real-time preferably, the accurate algorithm of detection, such as the commercial face critical point detection that Face++ is provided
Algorithm.
S4: the key point position is mapped to first display layer in real time, and will be corresponding in first display layer
The zone marker of the key point position is crucial display area；Key point position is mapped in real time in the first display layer
The zone marker of the different key point positions of correspondence can be further that the key of corresponding different human body organ is shown by coordinate position
Show region, for example, being eyes display area by the zone marker of corresponding eyes key point position, by corresponding mouth key point position
Zone marker be mouth display area, and so on.
Further, these crucial display areas are not shown in the first display layer, can be regarded as in the first display layer
The middle display object for constructing corresponding different human body organ, these organs show that object is transparent, and in the second display layer
The change of key point position and change.
S5: object, which carries out collision detection, to be shown to the crucial display area and preset interaction by physical engine.Its
In, the interaction shows that object can be indicated in originally on the first display layer, such as the elements such as lyrics, is also possible to detecting
It is then displayed at after to trigger condition on the first display layer.
Specifically, rigid body is set for the crucial display area by physical engine and shows object, such as by human body device
Official shows that object is set as rigid body and shows object.Then it according to preset trigger condition, controls preset interaction and shows that object exists
It is moved on first display layer according to preset sports rule, the interaction shows that object is that rigid body shows object；?
When interaction display object movement, collision inspection is carried out to the crucial display area and interaction display object in real time by physical engine
It surveys.
Further, the preset trigger condition includes externally input order, for example, user passes through mobile phone, requesting song
The equipment such as screen send order, after set-top box receives order, then a preset interaction display pair can be shown on the first display layer
As such as football object, and controlling it and being moved according to preset sports rule.
Further, the preset trigger condition can also include externally input interactive information, i.e., in the process of performance
In, user can by the terminals such as mobile phone to song-order machine set-top box send interactive information, interactive information include text, picture,
The multimedia resources such as video after set-top box receives interactive information, generate corresponding interaction and show object, and pass through physical engine
It is set to rigid body and shows object, be then shown in the first display layer, and control the interaction and show object according to default
Motion profile and movement velocity moved.
For collision detection, there are more physical engine library, such as Chipmunk2D at present, it is possible to determine that interaction display pair
As whether colliding with crucial display area, and then different feedbacks is generated, to realize interaction.In the concrete realization, may be used
To be developed using Unity, label interaction display object and crucial display area are rigid body, increase collision detection component, Ji Ke
The collision of interaction display object and crucial display area is detected in collision detection event.
S6: it when detecting collision, controls the interaction and shows that object is moved according to preset Feedback Rule.Its
In, preset Feedback Rule can follow actual physics rule and be set, and can also be carried out according to human organ behavioural characteristic
Setting, can also be according to other rule settings.
When preset Feedback Rule fully complies with physics law, specifically, when detect the interaction show object with
The key display area collides, then shows object according to the movement speed of the crucial display area, the interaction
Rebound direction and the ball rebound velocity of the interaction display object is calculated in movement velocity and collision angle；It controls described mutual
Dynamic display object is reversed according to the rebound and ball rebound velocity is moved.For example, when user to correspond to by changing posture
Football object is hit in the crucial display area on head, and football object can rebound.
When preset Feedback Rule is set according to human organ behavioural characteristic, when interaction display object and crucial viewing area
Domain collides, then interacting display object can be according to the change of the behavioural characteristic of the corresponding human organ in the key display area
Change, as corresponding feedback.Specifically, can the first key point position according to obtained in step S3, determine human organ behavior
Feature.For example, the key point position of available corresponding eyes, determines the shape of eyes, and then determine that eyes are to be in open
Eye shape state is in closed-eye state, can also obtain the key point position of corresponding mouth, determines the shape of mouth, and then really
Determining mouth is in state of opening one's mouth or to shut up state.When detecting collision, according to the corresponding people in the key display area
The variation of body organ behavioural characteristic controls the interaction and shows that object desalination disappears.For example, interaction display object collides correspondence
When the crucial display area of mouth, if being detected simultaneously by mouth becomes the state of shutting up from the state of opening one's mouth, interaction display pair is controlled
As gradually desalinating disappearance, the effect eaten up by mouth is formed.
Interface interaction, effectively save cost can be realized without depth camera in the present invention；Pass through face key point
Detection algorithm and human body attitude detection algorithm are combined with the performance of song-order machine and general amusement function, and user is allowed to sing process more
It is joyful, it allows KTV to increase more interaction enjoyment, improves the K song experience of customer.
