Fig. 2 is to schematically illustrate the state that the wearable device according to one embodiment of the invention is dressed on user's body
Figure.
With reference to Fig. 2, can dress on user's body according to the wearable device (100) of one embodiment of the invention.Such as,
The extremity such as the wearable arm in user of wearable device (100) or leg, or wearable in the trunk of user, the present invention couple
This is unrestricted, it is also possible to be worn on user's body at least some of including other positions (head, hand, foot etc.).
Or, wearable device (100) can also be located at the interior of any object (medicated cap, glove, footwear etc.) of being worn on user's body
Portion.
Wearable device (100) is worn on the extremity such as arm or leg (that is, the body that action is relatively large by user
Position) on when carrying out activity, wearable device (100) is worn on body by changing pattern and the user of the acceleration information shown

3 axial acceleration informations of low pass filter (152).In order to reduce error in data, 3 axial acceleration informations can
It is to collect in the cycle with the unit interval (such as, 500msec) of regulation.
Then, in the step s 420, control portion (150) are by comparing two axle sides in 3 axial acceleration informations
To the variable quantity of acceleration information, determine the wearing state of user.Referring in particular to Fig. 4, in step S421, control portion
(150) variable quantity of the first axial acceleration information in 3 axial acceleration informations and second axial is compared
The variable quantity of acceleration information.Now, control portion (150) can be by 3 axial acceleration informations, except being perpendicular to ground
The 3rd axial acceleration information beyond the axial acceleration information of residue first and the second axial acceleration
Data are used as the acceleration information that variable quantity is relatively more required.Then, in step S422, control portion (150) judge two axle sides
To the ratio of variable quantity of acceleration information whether exceed reference value.Here, reference value can be according to whether for passing through high pass
The acceleration information of wave filter (151) or different by the acceleration information of low pass filter (152).Then, in step
In S423, when described ratio exceedes reference value, the wearing state of user is defined as the first wearing state by control portion (150),

The figure of result；Fig. 8 is to schematically illustrate under the second wearing state by two axial acceleration informations of low pass filter
The figure of variable quantity comparative result.In Fig. 5 to Fig. 8, it is assumed that Y-axis is vertical axis.Understand, as shown in Figure 5 and 7 wearable
X-axis device (100) is dressed on the extremity such as the arm of user or leg and the change of the acceleration information of Z-direction
Change amount ratio, and the X-axis wearable device (100) as shown in Fig. 6 and Fig. 8 is dressed on the trunk of user and Z
The variable quantity ratio of axial acceleration information is different.In Fig. 5 to Fig. 8, employ each axial acceleration information
The absolute value of maximum/minimum deflection, but the present invention is not limited.
Then, referring again to Fig. 3, in step S430, control portion (150) are according to the wearing state of user and use difference
Algorithm measure the activity of user.Now, control portion (150) use the first algorithm to measure use under the first wearing state
The activity at family, uses the second algorithm to measure the activity of user under the second wearing state.Specifically, control portion (150)
Can be according to the first algorithm and use the 3 axial acceleration informations by high pass filter (151) under the first wearing state
Measure the activity of user.And control portion (150) can use by low pass filter (152) under the second wearing state

The activity assay method of user the most according to claim 6, it is characterised in that described first wearing state is institute
Stating the state that wearable device is dressed on the arm or leg of described user, described second wearing state is described wearable dress
Put the state dressed on the trunk of described user.
The activity assay method of user the most according to claim 6, it is characterised in that according to the work measuring described user
The step of momentum, under described first wearing state, is used and is come by the described 3 axial acceleration informations of high pass filter
Measure the activity of described user, under described second wearing state, use by low pass filter described 3 axial to add
Speed data measures the activity of described user.
10. the activity assay method of user, it is the method performed by computer system, it is characterised in that including:
Receive the step of the 3 axial acceleration informations detected by least one acceleration transducer,
In described 3 axial acceleration informations, compare variable quantity and the second axle side of the first axial acceleration information
To the variable quantity of acceleration information determine the step of mode of operation, and
Use the described 3 axial acceleration informations detected, measure the step of the activity of the user relevant with paces；
According to the step of the activity measuring described user, use the described 3 axle sides by the first wave filter in the flrst mode
To acceleration information measure the activity of described user, use described 3 axles by the second wave filter under the second mode
The acceleration information in direction measures the activity of described user.
