Select embodiment and with reference to accompanying drawing, technical scheme is further described, but the invention is not restricted to these embodiments.
Embodiment one
As shown in figure 1, present embodiment discloses a kind of method of rapid evaluation tennis sparetime level, user is in batting
Footwork can be divided into two kinds of situations:The first is normal regular random little step adjustment, and second is passive big step
Run adjustment, according to tennis characteristic, random little step adjustment is The more the better in user's batting, and big step is run, and means user
Mobilized by other side, it is more few better in the state that is forced to, so the present embodiment is run according to the adjustment of user's random little step with big step
Ratio between dynamic determines user's footwork score, and specific method includes:
A:The step situation of movement of user is monitored by 3-axis acceleration sensor 15, processor 11 receives 3-axis acceleration
Sensor 15 monitors obtained volume of data, and a series of places such as noise reduction, feature extraction are filtered to this volume of data
Footwork data are obtained after reason and are recorded, many algorithms can be realized to 3-axis acceleration sensor 15 in the prior art
The data monitored are handled to obtain step number and displacement, and the present embodiment can select one or more of which as the case may be,
Specific algorithm is not described in detail herein, and then processor 11 is used according to user's footwork data by footwork score statistical method
Family footwork score.
But in actual conditions, it is personal because the normal gait of sex, height, age, its different square stance of body weight is different,
So in step, before starting to judge user's footwork score, user needs first to input itself sex, height, body weight and year
The user profile such as age, the processor 11 of wearable device receives the user profile of user's input, true according to different user profile
Surely stride is preset, the default stride is used to judge that the stride of relative users belongs to the stride that random little step adjusts and still falls within big step
Run the stride of adjustment, default stride here determines according to user profile, and presets stride corresponding to corresponding user profile
Set by producer according to large database concept, the user profile of many tennis enthusiasts is record in large database concept and its was normally batted
Stride, arm in journey brandish the information such as amplitude, heart rate, and user profile can be classified as multiple shelves by producer according to large database concept information
Secondary user, such as 5 class, the corresponding default stride of each class, such as be followed successively by from high to low 0.32 meter, 0.31
Rice, 0.30 meter, 0.29 meter, 0.28 meter, for example, height 1.8, body weight 180, the boy student at age 32 is classified as the 3rd class use
Family, default stride is by as 0.30 meter corresponding to him.When coming into operation certainly, a kind of this feelings of the present embodiment are not limited to
Condition, its specific gear number, default stride corresponding to every grade etc. is by producer according to large database concept, actual conditions and default
Deng determination.
Specifically, footwork score statistical method includes:
A1:Intelligent wearable device 1 counts step number and the distance run in impact each time, and according to step number and
The distance run judges that the stride in corresponding impact is run for random little step adjustment or big step by stride decision method
Adjustment;
A2:Random little step adjustment total degree is counted in preset time period and big step is run and adjusts total degree, and will be small broken
Successive step total degree and big step adjustment total degree of running are done except obtaining footwork ratio;Signified preset time is equal in the present embodiment
By user's sets itself, setting means is that user opens intelligent wearable device 1 in setting in motion, starts to monitor and is counted
When, when terminating motion, user selects to terminate monitoring, stops timing, and preset time is this period of start to finish, and
When user's bait, pause can be selected to monitor, footwork, the gimmick of the intelligent pause of wearable device 1 monitoring user
And heart rate, until user's selection continues to monitor, avoiding continuing during user's bait monitoring influences evaluation result.
A3:Wearable device obtains user's footwork score further according to footwork ratio by footwork score decision method.
Wherein, because the process of tennis impact is intermittent, bat bat this to completion from starting to walk about each time
Period, certainly, generally after each batting terminates, user may adjust the position of oneself as an impact, but
It is that this position is not configured to bat, so, wearable device can't detect the batting of user and move in current walk process
Make, specifically walked about so wearable device is ignored automatically, avoid detection error.
Further, in step A1, stride decision method includes:
The distance moved in impact each time and step number are divided by obtain two strides, when stride is more than default stride
When, judge that the stride of this impact is run adjustment for big step, when stride, which is less than or equal to, presets stride, judge this time
The stride of impact adjusts for random little step, and certainly, default stride here determines according to current user information.
Specifically, in step A3, footwork score decision method includes:
When footwork ratio is more than or equal to 5, judge that user's footwork is scored at 1;
When footwork ratio is more than or equal to 4, during less than 5, judge that user's footwork is scored at 0.8;
When footwork ratio is more than or equal to 3, during less than 4, judge that user's footwork is scored at 0.6;
When footwork ratio is more than or equal to 2, during less than 3, judge that user's footwork is scored at 0.4;
When footwork ratio is less than 2, judge that user's footwork is scored at 0.2.
