Formula, has the advantages that interactive speed is fast, interactive mode is natural, greatly improves the game experiencing of user.
Below, each step in the game interaction method in exemplary embodiment of this disclosure is made further
It is bright.
In step s 102, default expression parameter of the user under default expression is obtained.
The game interaction method that the disclosure is provided goes for somatic sensation television game equipment, virtual reality device etc. has motion
The equipment of capture function.
It is motion-captured be it is a kind of for accurate measurement moving object three-dimensional space motion situation technology.It is based on calculating

Tracker) moving situation record in the form of images, the pictorial data is processed using acquisition machine then, from
And obtain the space coordinates of different objects (tracker) in different time measurement unit.
Further, in the illustrative embodiments of the disclosure, the step S102：Acquisition user is under default expression
Default expression parameter, can include：
Step S1022, obtains the first coordinate of the face feature point under user's normal condition.
First, user's face model and characteristic point are obtained by reverse modeling.Can be caught by the optical sensor of equipment
Catch the spectrum of user's facial muscles reflected light in normal state.These spectrum can be that natural light is incident upon on facial muscles
The spectrum, or equipment of reflected light are incident upon the spectrum of the reflected light on facial muscles.By the analysis to above-mentioned spectrum,
Can be reverse modeling --- by way of for example with surface reconstruction, user's face is modeled.
Surface reconstruction is a kind of reverse modeling method.During surface reconstruction, first discrete data point can be joined
Numberization, the then boundary formation initial surface according to data point block, and make the relative position of each data point on initial surface
To present, so as to be distributed by obtaining the respective parameter (u, v) of data point, each data point is set to turn into the real node of patch.
Order arrangement is being carried out to each node, such as the node order, node serial number and node parameter value to each node are ranked up
Afterwards, the patch with orderly multiple nodes can be obtained.
In this example embodiment, can be used as during surface reconstruction by obtaining the characteristic point of user's face
Data point.The international standard that MPEG-4 is defined to 3 D human face animation can be introduced herein【ISO/IEC 1988a】With【IOS/IEC
1988b】, both standards all include determining to FAP (facial animation parameter, people' s face positioning)
Justice.FAP is a kind of parameter with versatility, can be used to represent face exercise data, and its value is generally with FAPU (facial
Animation parameter unit, people' s face positioning unit) be unit so that same FAP be applied to it is different
When on model, generation is same muscle change.
In this example embodiment, default facial expression can include narrowing ocular feelings and aiming at expressing one's feelings.Therefore, this step
The motion of user's periocular muscle can be included obtaining, so as to obtain the expression of the user.Can be by frontalis, temporalis, eye wheel circle
The periocular muscles such as flesh, superciliary corrugator muscle nasalis, musculus as the muscle that can at utmost reflect user's expressive features, in these muscle
Characteristic point is marked on position, then the locally fine point near the eyes of user is obtained by the reverse modeling mode such as surface reconstruction.It is worth mentioning
, reverse modeling mode is not limited to that, relevant technical staff in the field according to actual conditions when can select reverse modeling
Mode.
After the mask for obtaining user, with selected characteristic point, and the coordinate of these characteristic points can be recorded.By now
User's face characteristic point coordinate record is the first coordinate, to represent user's facial expression feature in normal state.
Step S1024, obtains the second coordinate of the face feature point of the user under the default expression.
User can be pointed out to make default expression.The method of user is pointed out to include but is not limited to be regarded in interface
Feel prompting, audio prompt etc. is carried out by equipment.After above-mentioned prompting is sent, can by carry out image procossing, analysis with
Pattern-recognition, the coordinate of the above-mentioned user's face characteristic point of real-time capture, to judge user's face muscular movement, and in user's face
Muscle keeps the expression of steady time recording user.
Can be the second coordinate by user's face characteristic point coordinate record now, to represent user under default expression
Facial expression feature.
Step S1026, the default expression parameter is obtained according to first coordinate with second coordinate.
The distance between selected characteristic point can be drawn according to the first coordinate to obtain first facial expression parameter K0, according to
Second coordinate draws the distance between selected characteristic point to obtain the second Facial Animation Parameters K1, the ratio K 1/ of calculating K1 and K0
K0, default expression parameter is recorded as by the ratio.
When default facial expression includes narrowing ocular feelings and aiming at expression, the default expression parameter of user is obtained except obtaining
The coordinate of user's periocular muscle characteristic point, it is also possible to including obtaining the sight line focal position under user's normal condition.For example, can be with
The sight line focal position of user is determined by following the trail of user's pupil position, and the position is advance according to the coordinate of display interface
Set, when detecting user's sight line focus and staying in the position more than preset time threshold, then trigger corresponding trip
Play operation (e.g., in shooting game, performs and aims at focusing and shoot).
In step S104, the real-time expression parameter of user is obtained.
By following the trail of above-mentioned face feature point, to obtain the 3rd coordinate of the face feature point, and according to described first
Coordinate obtains the real-time expression parameter with the 3rd coordinate.Remember the distance between selected characteristic point according to the 3rd coordinate
To obtain the 3rd Facial Animation Parameters K2, expression parameter can for example be represented by K2/K0 in real time.
In step s 106, the default expression degree of user is judged, the default expression degree characterizes expression and institute in real time
State the degree of approach between default expression.
By real-time parameter and the default expression degree of the ratio in judgement user of the default expression parameter of expressing one's feelings.Example
Such as, the degree of approach between expression in real time and default expression can be obtained by K2/K1.
In step S108, according to the default expression degree adjustment game display interface.
After drawing above-mentioned user's expression judged result, can be according to the degree of approach adjustment between expression in real time and default expression
Game display interface.For example, when the ratio is more than or equal to 1, interface is preset in display.When the ratio is more than 1, represent
The real-time expression of user presets the facial muscle movements scope of expression beyond l, is excessively made that default expression；When described ratio etc.
When 1, represent that the real-time expression of user is sufficiently close to default expression, it is believed that user is made that default expression.Therefore, user is worked as
When making default expression or excessively making default expression, default interface can be shown.
When default expression includes narrowing ocular feelings and aiming at expression, display interface now can be the maximum for allowing display
Interface (can for example include foresight or aim at window) is aimed at visual focusing interface.In the other embodiment of the disclosure
In, when default expression includes other expressions, above-mentioned default interface can also be other display interfaces, this area correlation technique
Personnel work as can implement according to actual conditions.
Meanwhile, when default expression includes narrowing ocular feelings, and when the ratio is less than 1, can be adjusted according to the ratio
The focal length of game display interface.Herein, it is believed that when the ratio is less than 1, the facial muscle movements of user are not up to
The facial muscle movements scope of default expression, it is to narrow ocular feelings for example to preset expression, and user's narrows a degree and may simultaneously be not up to
It is default narrow ocular feelings narrow a degree.At this point it is possible to narrow a focal length for degree adjustment game display interface, example according to user
Such as, user to narrow a degree bigger, narrow a degree closer to default, then the focal length of display interface of playing is bigger, and user can see
Relatively farther scene；User narrows that a degree is smaller, closer to the facial expression of normal condition, the then focal length of display interface of playing
It is smaller, closer to user normally express one's feelings in the case of the game display interface that can see.
More obscure at a distance or when sight line is unintelligible not seen due to people, can subconsciousness to narrow eye farther to see
Object, therefore, by the above method, change that can be by detecting the circumocular muscle of people judges whether user is made that and narrows eye
Expression, so as to judge whether user has the demand for checking farther target.Shown with game by the ocular feelings degree of narrowing for setting up user
Show scale parameter relation between the focal length at interface, it is possible to use family controls game to show by subconscious facial muscle action
Interface, the game display interface of demand is more met so as to see.Similarly, when user makes aiming expression or other default expressions
When, the above method can also make game display interface show that game aims at interface or other game for meeting user's request show boundary
Face, the disclosure is not particularly limited to this.
Embodiment of the present disclosure implementation method is described in detail below by specific embodiment.
Fig. 2 is the schematic diagram of human face's characteristic point that MPEG-4 standards specify.
With reference to Fig. 2, in MPEG-4 standards, FAP includes 84 face feature points, and face feature point can be ordered by position
Name.In the present embodiment, can be using iris diameter, two centre distance, eyes-nose distance as can most characterize user's eye

Parameter K2, and the default facial expression degree of user is obtained according to K2, for example narrow a degree.
When default facial expression for narrow ocular feelings when, can set game display interface visual range initially show focal length as
J0, it is allowed to which the maximum focal length that can be seen is J1, and (K1/K0)=a (J1/J0), the wherein value of constant a can be by (K1/K0)/(J1/
J0) determine.
At this point it is possible to obtain the corresponding relation J=between the focal length J of game display interface and user's face expression parameter K
K/a.Because real-time face expression parameter is represented by K2/K0, therefore, determine the real-time of real-time game display interface by calculating
Display focal length J2, and according to J2 adjustment game display interfaces.
Fig. 4 A are that disclosure example embodiment mid-focal length is the game display interface for initially showing focal length J0.Fig. 4 B are this public affairs
It is the game display interface for showing focal length J2 in real time to open example embodiment mid-focal length.
With reference to Fig. 4 A~Fig. 4 B, when user makes normal expression, K2=K0, J2=J0, display focal length are the game of J0
Display interface；When default expression degree is less than 1, J2 ＜ J1, display focal length is the game display interface of J2；When default expression journey
When degree is more than or equal to 1, it can be deduced that J2 >=J1, maximum focal length J1 now can be still shown.
