Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present invention is described.Should be understood that in all the drawings, identical label represents identical parts or assembly.
Fig. 2 shows the process flow diagram of the user operation recognition methods of the multisensor according to the embodiment of the present invention.
First, in step 210, equipment carries out initialization operation.Particularly, equipment is in system electrification and when starting, the equipment of judging whether has hardware sensor.If equipment does not exist any hardware sensor, then proceed to other initialize routine sections and perform, and do not start the software service of operation recognition methods involved in the present invention.If determine that equipment has hardware sensor, then to the module of software and hardware initialization of equipment.Except carrying out except initialization to each sensor driver module in this initialization procedure, also by the software virtual one virtual controlling equipment of equipment, and initialization is carried out to virtual controlling equipment.Virtual controlling equipment carries out initialization mainly to be needed to arrange hardware sensor list, sampling period, predefined operation instruction etc.More than operation can such as have been come by the operating system (OS) of equipment.If above initialization procedure is unsuccessful, then proceeds to other initialize routine sections after carrying out error handle and perform, if initialization success, then hardware sensor and virtual controlling equipment are started working.
Next, in step 220, each sensor detects respective state parameter respectively, and the state parameter detected is sent to virtual controlling equipment; The respective state parameter that virtual controlling equipment obtains from multiple sensor when receiving and be recorded in each sampling, is formed and the state parameter collection of at every turn sampling corresponding.According to present example of the present invention, sensor can comprise the modules such as electronic compass, gravity sensor, gyro sensor.Wherein, electronic compass utilizes terrestrial magnetic field to determine the direction of south poles, and using magnetic direction as the benchmark of horizontal direction.Gravity sensor is the sensor utilizing piezoelectric effect to realize, and its component size measuring the orthogonal both direction of gravity judges the change of horizontal direction and vertical direction.The benchmark that it is horizontal direction that gravity sensor utilizes with the magnetic direction of electronic compass acquisition.Gyro sensor utilizes the responsive housing relative inertness space of the momentum moment of high-speed rotator to carry out angular motion detection around or two axles being orthogonal to the axis of rotation, thus can the angular velocity of checkout equipment and angular acceleration.Also can comprise other various sensors other state parameters for checkout facility according to the equipment of the embodiment of the present invention, not enumerate at this.Repeat above step, the state parameter collection of predetermined quantity can be obtained within certain sampling period, be called the group of a state parameter collection.In the present embodiment, suppose that state parameter comprises angular velocity, acceleration, horizontal direction change, the state parameter set representations in first sampling period is { a
1, b
1, c
1, d
1, the state parameter set representations in second sampling period is { a
2, b
2, c
2, d
2... by that analogy, the state parameter set representations in the n-th sampling period included by one group of state parameter collection is { a
n, b
n, c
n, d
n.It should be understood that, state parameter collection can comprise other status parameter values.
Then, in step 230, virtual controlling equipment determines that certain the specific status condition whether the state parameter collection recorded meets in multiple status condition is corresponding.Here, each status condition comprises multiple condition component, and each condition component comprises the predefined parameter value corresponding with each sensor in multiple sensors of subscriber equipment.Describe in detail with reference to Fig. 3 after a while and determine whether the state parameter collection recorded meets the process of certain particular state condition.
Next, in operation 240, determine whether to perform the user operation corresponding with certain status condition according to the judged result of step 230.Such as, if determine that the group of state parameter collection corresponds to certain specific status condition α in step 230, then the user operation corresponding with status condition α is performed.Here user operation can be by the predefined operation of user.Such as, if when user uses mobile terminal, control that webpage retreats, quits a program by operating mobile terminal, input character etc.
Finally, after user operation completes, remove the state parameter collection recorded in step 250, and restart the state parameter collection receiving the next sampling period.
Describe in detail below with reference to Fig. 3 in the step 230 of Fig. 2 and determine whether the state parameter collection recorded meets the process of certain status condition.
First, in step 231, virtual controlling equipment determines that each state parameter collection by the one group of state parameter received is concentrated compares with each condition component in multiple status condition, respectively in order to determine that whether this group state parameter collection is corresponding with certain particular state condition.Particularly, virtual controlling equipment can determine the first state parameter collection { a in the group of the state parameter collection of the record comprising predetermined quantity

1, d
1in each state parameter whether meet first condition component in some status conditions, that is, determine angular velocity a respectively
1, acceleration b
1, horizontal direction change c
1, vertical direction change d
1whether meet the first condition component in certain status condition.Here there is multiple status condition in hypothesis, and each predetermined condition has different condition components, the user operation that each status condition is corresponding different.If determine the first state parameter collection { a
1, b
1, c
1, d
1({ w is assumed to be with the first condition component in some status conditions (being assumed to be condition α)

1) corresponding, then continue to determine the second state parameter collection { a
2, b
2, c
2, d
2second condition component { w whether in eligible α
2, x
2, y
2, z
2.By that analogy, until determine whether n the state parameter collection concentrating of this group state parameter obtained distinguishes each the condition component (232) in all eligible α, then deterministic process returns "Yes", thus carries out step 240 to perform the user operation corresponding with condition α.
If the result determined in step 231 is that the one group of state parameter collection obtained does not meet any status condition (233), then deterministic process returns "No", thus proceeds to step 250, abandons the state parameter collection recorded.Such as, if determining the state parameter collection { a that one group of n state parameter is concentrated

2, z
2, then determine that this group state parameter collection does not meet any status condition.
If the result determined in step 231 is one group of current state parameter collection { a
