Abstract
Disclosed are a method for controlling a three-dimensional virtual space on a screen by motion recognition, and a control device therefor. The control method of the present invention enables the rotation of a virtual space by extracting an angular velocity according to a motion using a sensor, generating a rotation value in proportion to the angular velocity, and transmitting the same to a computer and the like. If a relative rotation angle continuously increases or decreases according to a motion, a rotation value is generated in consideration of a weight in proportion to the relative rotation angle as well as the angular velocity, thereby enabling a control device to not go far away from the rotation and to rapidly return to the center of a screen even when a motion of rapidly rotating a virtual space is made.
Description
Technical field
The present invention relates to three on a kind of picture for showing based on action recognition mode control first person
Method and the action recognition of dimension Virtual Space control device.
Background technology
Recently, various application programs are not only arranged at individual's computer, are also equipped with various application journey at television set etc.
Sequences etc., have therefore been developed a kind of pointer (Pointer) such as display highlighting (Cursor) on picture, and have inputted the control of user
The control device (or input equipment) of order.Have as the device being widely used for inputting the controlling device of control command
Mouse (Mouse), remote controller (Remote controller) or control bar (Joy Stick).Recently, action recognition controls
Device is come on stage with the form of development further.Action recognition controls device equipped with for identifying the sensor of various posture,
And identify the intention of user according to action recognition algorithm.
Due to the convenience of use, action recognition controls the use of device and is being gradually increased.But, according to situation,
Directly should not be reflected reality the action in the world, and may need to make a reservation between the control in the action and picture of reality
Adjustment.Typically, the first person shooting mould of FPS (first person is shot, First-Person Shooter) it is referred to as
Intend game the most so.
The game of first person shoot-simulating shows 2.5 dimensions Virtual Space to 3-dimensional of first person on picture.Enter
And, the pointer as the benchmark controlled shows the center at picture always.If it is with moving images such as mouses, the most virtual
Three dimensions moves, and is fixed on the center of picture all the time as the pointer of the benchmark of first person.
Because the multiple restriction that action recognition controls, mouse is still as the control device for controlling first person game
And be widely used.Now, comparing mouse and cannot perform other functions in addition to the input function of control command, action is known
Kong Zhi not have the effect that the Virtual Space on picture is extended to realistic space by device, therefore can improve the people's of object for appreciation game
Degree of immersing also makes game more interesting.
Action recognition controls the limitation of device and is, the actual three dimensions in reality and the Virtual Space of embodiment in plane
Inconsistent.As a example by Fig. 1, this situation is illustrated.
Fig. 1 is roughly to illustrate to utilize action recognition to control device and control the figure of the situation of first person Virtual Space.
Picture 10 shows virtual three dimensional space 10a.If player's rotating control assembly 20, the then three-dimensional on picture 10
Space 10a moves with this and proportionally rotates.In this rotary course, the viewpoint as the user of the benchmark controlled shows all the time
Show the center at picture 10.
Player in order to made by action control picture 10 Virtual Space 10a rotate more than 180 °, player or control
The posture of device 20 processed needs the anglec of rotation with Virtual Space proximally to rotate.Even if problematically, player rotates close
180 ° and make Virtual Space 10a rotate more than 180 °, actual picture 10 is also integrally fixed at this position.Player can be produced backwards
Side, and the situation that picture 10 is the most located anteriorly.The situation that second time controls is carried out immediately after the rotation of Virtual Space 10a
Under, this situation necessarily causes inconvenience.And then, when controlling device 20 and moving towards picture 10 ground, perform new action control
And make the Virtual Space 10a in picture 10 rotate the most round about.
In action recognition, the rotary speed of Virtual Space is generally directly proportional with the angular velocity of control device action and true
Fixed, therefore, if making control device move rapidly, then Virtual Space will quickly rotate.Even so, along with entering of rotating
OK, player or control device are separated by from picture and still can see the situation in diverse place.
Only solve the targeted this problem of the present invention just can make based on action recognition mode to include that the first person is penetrated
The action control of the first person Virtual Space hitting game is smooth.

Under condition, control device 200 and preferably there is Wireless/wired USB interface, and computer etc. 30 can identify controlling device 200
Become mouse.
The action recognition portion 230 controlling device 200 utilizes sensor 210 and the posture of identification control device 200, and calculates
The angular velocity of current action and " relative rotation angle ".
Wherein, relative rotation angle is the anglec of rotation of the current posture changed along with action from default benchmark posture
Degree.The anglec of rotation is the angle for showing the postural change in three dimensions, and it uses Eulerian angles (Euler typically
Angle) etc..According to situation, the angle of pitch (Pitching angle), roll angle (Rolling angle), yawing angle also can be used
(Yawing angle) represents.Therefore, the anglec of rotation can be the anglec of rotation in a plane, but generally represents three-dimensional space
The interior anglec of rotation.Hereinafter, with " Eulerian angles ", the anglec of rotation is illustrated.Therefore, relative rotation angle is benchmark posture
Under the difference of the anglec of rotation and present rotation angel degree.
Benchmark posture both can use default fixed value, it is also possible to by the benchmark posture configuration part 250 of following description
And arrange.
Control the posture of device 200 be equivalent to include forward/backward wait the rotations such as movement, pitching/rolling/yaw and
The action of the action etc. combined by them.Obviously, control device 200 or the action recognition portion 230 of the present invention can identify
This major part posture or movement.But, the invention particularly relates to spinning movement therein, so omitting other actions
The explanation identified, and illustrate centered by spinning movement.Therefore, the rotation of action recognition portion 230 identification control device 200
Action, and identify the relative rotation angle on the three dimensions according to the angular velocity rotated and relative datum posture.
First, sensor portion 210 is equipped with the sensor needed for action recognition, thus obtains the posture controlling device 200
(Position) information.The sensor being widely used in action recognition has gyro sensor (Gyroscope), geomagnetic sensor
(Geo-Magnetic Sensor) and acceleration transducer etc., sensor portion 210 is also equipped with gyro sensor 211, earth magnetism
Sensor 213 and acceleration transducer 215.Gyro sensor 211 measures in rotary moving each of an axle or multiple axle
Variable quantity, geomagnetic sensor 213 is for utilizing earth's magnetic field to measure the absolute direction of magnetic.Acceleration transducer 215 is measured
Linear acceleration and angle of inclination.
Action recognition portion 230 is primarily based on the gyro sensor 211 in sensor portion 210, geomagnetic sensor 213 and accelerates
The degree sensing value that provided of sensor 215 and the angular velocity of calculation control device 200 and current posture (the 1st step), then count
Calculate the relative rotation angle (the 2nd step) between benchmark posture and current posture.
Benchmark posture configuration part 250 is receiving control command (that is, " benchmark arranged about benchmark posture at user
Posture setting command ") in the case of, the current pose information controlling device 200 provided in action recognition portion 230 is arranged to
Benchmark posture.Benchmark posture be as following description rotate calculate benchmark control device 200 pose information, such as with
The form of Eulerian angles and angular velocity is stored." benchmark posture setting command " can by special button (not shown) or its
His input block etc. and at user, directly accept input.
It addition, as the most again illustrated, the control device (200) of the present invention can drive under two patterns (Mode)
Dynamic.One is general mode, and another is rolling mode.User can be by input conversion general mode and rollings such as push-botton operations
" the patten transformation control command " of dynamic model formula.The following description, in the case of not having special records, is under " rolling mode "
Explanation.
In the case, if receiving " the patten transformation control being transformed into rolling mode for request from general mode
Order ", then benchmark posture configuration part 250 is judged as there is " benchmark posture setting command ", and can be by action recognition portion 230
The current pose information controlling device 200 provided is arranged to benchmark posture.
It addition, as set forth above, it is possible to by posture on the basis of fixed value use, therefore benchmark posture configuration part 250 is not this
The necessary element of invention.On the basis of fixed value is used in the case of posture, such as can be in certain of control device 200
Under the state that a part is fixed on ad-hoc location, may apply to can the situation of pitching/rolling/yaw.Or, can pacify existing
In the case of pedestal (Station) device that dress and releasably supporting control device 200 and position are fixed, it is possible to use fixing
Benchmark posture.
Angular velocity and relative rotation angle that rotational value generating unit 270 is provided based on action recognition portion 230 and generate use
In the rotational value of the Virtual Space made shown by computer etc. 30, and the rotational value of generation is supplied to computer 30.Rotational value
It it is the value of the form arranged between 30 and control device 200 at computer etc. according to the rotation for Virtual Space.Passing through
In the case of USB interface is connected to computer etc. 30, rotational value can be with the mouse as usual computer input unit
(Mouse) output format is uniformly set.
In the case of rotational value is mouse output format, rotational value includes directional information and mobile size information, and
And rotational value generating unit 270 (such as 10ms) at predetermined intervals and rotational value is supplied to computer etc. 30.Therefore, meter
Calculation machines etc. 30 will make Virtual Space rotate based on rotational value.
Rotational value is substantially determined by the value being proportional to angular velocity.Hereinafter, angular velocity will be only proportional to distinguish
Rotational value is referred to as " basic rotational value ".The general mode being described above or rotational value of the prior art are to be only proportional to angle speed
The basic rotational value of degree.Therefore, if the action controlling device 200 accelerates, then the rotation of virtual screen also can accelerate；If it is dynamic
Make slack-off, then the rotation of virtual screen is the most slack-off.But, in the scenario above, spinning movement and the rotation of virtual screen
Unloading is in the relation of direct ratio, it is thus possible, for instance rotated by quick action at control device 200 and make Virtual Space rotate 180 °
In the case of, control device 200 the most at least half-twist and can only be in depart from picture state, therefore can occur picture from
The visual field at family away from phenomenon.
In the present invention, the method being added or being deducted weighted value by the action according to control device 200 determines rotational value.
By the control of this weighted value, the present invention controls realistic space and the picture that device 200 can solve to illustrate in prior art
The inconsistent situation in the space on face.
Hereinafter, with reference to Fig. 4 to control device 200 action control operation illustrate.
<benchmark posture sets: S401>
Such as above-mentioned example, if receiving " benchmark posture setting command " from user, then benchmark posture configuration part 250 will be dynamic
Make identification part 230 and be set to benchmark posture in the posture controlling device 200 that this moment provides.Therefore, in action recognition portion 230
In the case of Eulerian angles are provided, these Eulerian angles are set to benchmark posture.
<calculate relative rotation angle based on action recognition: S403, S405>
After arranging benchmark posture, if the sensing value of detecting part 210 changes, then action recognition portion 230 is judged as
There is the movement (S403) controlling device 200, and calculate relative rotation angle (S405) based on this action.
As it has been described above, relative rotation angle is current posture and the difference of benchmark posture, and the calculating of relative rotation angle
Method can be realized by geometric mode.
<calculating of rotational value: S407>
Rotational value is substantially tried to achieve by the value being proportional to angular velocity.To this, it is suitable for weighted value in the situation and makes void
The rotation intending space 10a relation control device 200 rotates more or less rotates.
1.Relative rotation angle persistently becomes big situation along with action
In the case of the relative rotation angle provided in action recognition portion 230 persistently becomes greatly, rotational value generating unit 270 profit
Rotational value is calculated by the value by angular velocity (determining basic rotational value) and the first weighted value.Now, the meter of relative rotation angle
Calculation has clearly a need for calculating according to its direction, but as long as relative rotation angle becomes big, then independently applies first with the direction
Weighted value.
In other words, in the case of the relative rotation angle provided in action recognition portion 230 persistently becomes greatly, such as following mathematics
Shown in formula 1, rotational value is proportional to angular velocity and the first weighted value sum.
Mathematical expression 1
Rotational value] (angular velocity the+the first weighted value)
According to the rotational value corrected by said method, the rotation of Virtual Space 10a becomes ratio and controls the relative of device 200
Gathering way faster of the anglec of rotation, even if the most somewhat making a movement, Virtual Space 10a also can rotate more.
First weighted value is directly proportional to relative rotation angle.According to embodiment, rotational value generating unit 270 can be according to as follows
Mathematical expression 2 try to achieve the first weighted value.
Mathematical expression 2
Wherein, sensitivity is the arbitrary preset constant such as 3,5,7.According to mathematical expression 2, the first weighted value is proportional to relatively revolve
Gyration and the product of acceleration, and be inversely proportional to sensitivity.Therefore, rotating against that action recognition portion 230 is provided
In the case of angle persistently becomes greatly, the rotary speed of Virtual Space 10a becomes the big and shifting of action along with relative rotation angle
Move and accelerate and accelerate.
2.The situation that relative rotation angle persistently diminishes along with action
The action that relative rotation angle persistently diminishes is to control device 200 to return to the situation of basic form.Such as, user is worked as
Make control device 200 rotate from basic form and carry out relative rotation angle and persistently become big to make Virtual Space 10a rotate
Movement in the case of, control device 200 and be in the state of the center predetermined distance from picture 10.Picture 10 display centre
Point is positioned at the first person Virtual Space 10a at the center of picture 10.For second time control, controlling device 200 needs again to move
Dynamic with the center towards picture 10.Further, user can arrange control device 200 the most again so that it is towards in picture 10
The heart.Now, relative rotation angle persistently diminishes towards benchmark posture.
In the case of relative rotation angle persistently diminishes along with action, rotational value generating unit 270 uses from angular velocity
(determining basic rotational value) deducts the value of the second weighted value and calculates rotational value by mathematical expression 3.Now, the meter of relative rotation angle
Calculation has clearly a need for being calculated according to its direction, but as long as relative rotation angle diminishes, then independently applies with the direction
Two weighted values.
Mathematical expression 3
Rotational value] (angular velocity the-the second weighted value)
According to mathematical expression 3, in the case of the relative rotation angle provided in action recognition portion 230 persistently diminishes, rotate
Value is proportional to angular velocity and the difference of the second weighted value.Wherein, the second weighted value 2 can be by the one-tenth ratio corresponding to relative rotation angle
The value of example determines, for example, it is possible to obtained by the method identical with mathematical expression 2.
According to embodiment, in the case of relative rotation angle persistently diminishes along with action, the preferably tune to rotational value
Whole setting boundary.
First, in the case of relative rotation angle is within default " limited angular ", inapplicable second weighted value.
Wherein, limited angular is to need to apply basic rotational value to carry out the region of common control.Such as, as shown in Figure 3, it is assumed that
On the vertical line a at the center of picture 10, be provided with the basic form controlling device 200, then can be by from controlling device 200
The center of rotation c one side that extends to picture line b and vertical line a between angle d be set to limited angular.Accordingly, exist
In limited angular, the second weighted value can not be used to make Virtual Space 10a rotate according to basic rotational value.
In the case, the second weighted value of mathematical expression 2 such as can be adjusted by following mathematical expression 4.
Mathematical expression 4
Second, even if application the second weighted value, minimum rotational value also can be set.Assume the rotational value that weighted value is " 0 ",
That is, basic rotational value is 100%, then become big along with relative rotation angle, and the second weighted value also becomes big, and therefore rotational value can be
The 70% or 60% of basic rotational value.But, if rotational value is too small, then cannot experience the rotation of Virtual Space 10a, because of
This is preferably provided with predetermined limit value.Therefore, even if in the case of relative rotation angle persistently diminishes along with moving, also can set
Put boundary to prevent rotational value from dropping to the default minimum rotational value (such as, 60%) on the basis of benchmark rotational value 100% below.
With reference to Fig. 3, it is assumed that the sensitivity in the example of mathematical expression 4 is 1, and second condition stating of application first and make limit
Controlling angle is 20 °, and minimum rotational value is 60%, and relative rotation angle is gradually reduced from 90 °.It it is 90 ° in relative rotation angle
In the case of, not calculating rotational value with 70% and apply minimum rotational value to become 60%, rotational value maintains 60% until relatively
The anglec of rotation reaches 60 °.Further, when relative rotation angle reaches 30 °, rotational value is recovered to 90%.Work as relative rotation angle
When being 20 °, rotational value recover form to 100% on the basis of rotational value.
According to the rotational value corrected by said method, Virtual Space 10a rotates less than the relative rotation controlling device 200
The speed that gyration diminishes, even if the most more moving, Virtual Space 10a only can somewhat rotate, and controlling device 200 can subtract
Lack the rotation of Virtual Space 10a and quickly return to the central authorities of picture 10.
3.Another embodiment that relative rotation angle persistently diminishes along with action
According to another embodiment, continuously repeat, controlling device 200, the action stopped after relative rotation angle persistently becomes greatly
After, in the case of carrying out the action of minimizing relative rotation angle, the second weighting of application in the example than above-mentioned 2. can be applied
It is worth bigger weighted value.Obviously, the second weighted value can be applied in the same manner and apply extra weighted value.
For example, it is assumed that user makes control device 200 rotate to the right from benchmark posture, (relative rotation angle becomes big moving
Make).After user rotates once to the right, then come back to the feelings of basic form (action that relative rotation angle persistently diminishes)
Under condition, the algorithm of the second weighted value of explanation in application deduction above-mentioned 2..Wherein, user for several times continuously and the most to the right
In the case of rotation, control device 200 and be necessarily separated by farther from picture 10.At this time, it may be necessary to deduction is than the second current weighted value
Bigger weighted value, could reduce the rotation of Virtual Space 10a and make control device 200 quickly return near basic form.Example
As, the method again deducting preset value from the rotational value that mathematical expression 3 is tried to achieve can be applied.
To this end, the relative rotation angle that action recognition portion 230 is provided by rotational value generating unit 270 persistently becomes greatly and fits again
Time the number of times of action that stops count, and in the case of there is the action that relative rotation angle diminishes, count initialized
In number of times.By repeat said process, rotational value generating unit 270 judge counts whether more than benchmark number of times, and
When reaching more than benchmark number of times, mathematical expression 3 and 4 adds in second weighted value of application the weighted value of predefined size.
<rotation according to the Virtual Space of rotational value: S409>
The rotational value of calculating is supplied to the Virtual Space display part 31 of computer etc. 30 by rotational value generating unit 270, and makes
Virtual Space display part 31 rotates Virtual Space 10a.
The action control controlling device 200 of the present invention is performed by said method.
<embodiment: the movement of benchmark posture>
The purpose performing above method is, direction to be arrived in user arrives Virtual Space 10a and stop
During the rotation of Virtual Space 10a, control device 200 is made to also return to benchmark posture.But, first when relative rotation angle becomes big
The application of the second weighted value when the application of weighted value diminishes from relative rotation angle is different, even if therefore relative rotation angle becomes
Returning to after Yuan in situ, Virtual Space 10a is likely to return to original position.The result repeating said process is, controls dress
The posture putting 200 is not benchmark posture, but Virtual Space 10a is positioned at desired position, but control device 200 for a long time with
It it not the posture stop of benchmark posture.
In order to solve the problems referred to above, the posture of the inclination of benchmark posture configuration part 250 identification control device 200, and to work as
Benchmark posture is made to move to direction in contrast on the basis of front benchmark posture.
The posture of the deflection controlling device 200 can be set to following posture, and action recognition portion 230 is at Preset Time
The posture more with the abundance being distributed as basis of relative rotation angle of interior offer.By Eulerian angles, benchmark posture is being set
In the case of, make its rightabout to the many angle of abundance move on the basis of current base posture (benchmark Eulerian angles).Or
Person, the relative rotation angle provided in Preset Time in action recognition portion 230 weighs to every specific direction from benchmark posture
In the case of subdivision cloth, the direction can be defined as the posture of deflection.
Accordingly, it is achieved the effect that Virtual Space 10a moves towards the deflection posture controlling device 200.
Above, to being shown according to a preferred embodiment of the invention and illustrating, but the invention is not restricted to above-mentioned spy
Fixed embodiment, in the case of the spirit of the invention being claimed in without departing from claims, belonging to the present invention
