Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings according to embodiments.
Generally, a user has a relatively small amount of activity indoors and a relatively large amount of activity outdoors. Based on the rule, whether the activity space of the user is switched between indoor and outdoor is judged according to the change of the outdoor activity amount.
On the other hand, if the activity space of the user is switched, the outdoor activity detection result of the user can be changed under normal conditions, for example, when the activity space of the user is transferred from the outdoor to the indoor, if the outdoor activity is detected based on the light intensity, the outdoor activity can be determined to be changed into the indoor activity due to the change of the light intensity (the light intensity is changed from strong to weak when the outdoor is irradiated by sunlight in the daytime and is transferred from the outdoor to the indoor, and the light intensity is changed from weak to strong when the outdoor is transferred to the indoor at night due to the indoor lighting); if outdoor activity is detected based on GPS signal strength, it can be determined that outdoor activity is changed to indoor activity due to a change in GPS signal strength (GPS signal strength is changed from strong to weak when moving from outdoors to indoors).
It can be seen that the change in the user's activity space, inferred from the change in the user's step-counting data, should be consistent with the outdoor activity detection results: if the results of the two adjacent outdoor activity detections are the same (indicating that the wearable device user is always outdoors or always indoors), the step counting data of the wearable device user between the two adjacent outdoor activity detection times should also indicate that the activity space of the wearable device user is not switched between outdoors and indoors; if the results of two adjacent outdoor activity detections are different (indicating that the wearable device user is located at a position switched from outdoor to indoor or from indoor to outdoor), the step counting data of the wearable device user between the two adjacent outdoor activity detection times should also indicate that the activity space of the wearable device user is switched between outdoor and indoor. Therefore, the outdoor activity detection result is checked and corrected based on the change of the user activity space, and the accuracy of the outdoor activity detection result can be effectively improved.
The following provides a detailed description of the principles of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for improving accuracy of outdoor activity detection according to an embodiment of the present invention, the method is applied to a wearable device, and a pedometer is configured in the wearable device, as shown in fig. 1, the method mainly includes the following steps:
step 101, collecting step counting data of a wearable device user in each step counting period by using a pedometer, and determining whether the activity space of the wearable device user is switched between outdoor and indoor in the step counting period according to the step counting data of the wearable device user in the step counting period.
102, carrying out outdoor activity detection on the wearable device user, judging whether the outdoor activity detection result of the wearable device user is accurate or not according to the judgment result of whether the activity space of the wearable device user in each step counting period is switched or not, and correcting the outdoor activity detection result of the wearable device user if the outdoor activity detection result is not accurate.
In this embodiment, a step counting threshold is preset based on an actual statistical result or experience: and if the step counting data of the wearable device user in a period of time is larger than the preset step counting threshold value, the activity space of the wearable device user is considered to be switched between the outdoor and the indoor in the period of time, otherwise, the activity space of the wearable device user is considered not to be switched between the indoor and the outdoor in the period of time.
Wearable equipment periodically collects step counting data of a wearable equipment user, and judges whether the activity space of the wearable equipment user changes in each step counting period based on the step counting data of the wearable equipment user in each step counting period, wherein the method specifically comprises the following steps: if the step counting data of the wearable device user in the step counting period is larger than a preset step counting threshold value, determining that the activity space of the wearable device user is switched between the outdoor and the indoor, otherwise, determining that the activity space of the wearable device user is not switched between the outdoor and the indoor.
Recording the detection time of the outdoor activity as TcThe time of the previous outdoor activity is recorded as TlIf the step counting data indicate that the activity space of the wearable device user is not switched between outdoor and indoor in the step counting period covered by the time range from Tc to Tl, the outdoor activity detection result of the time is consistent with the outdoor activity detection result of the previous time, otherwise, the outdoor activity detection result is inaccurate; if the step-counting data indicates an activity space of the user of the wearable deviceAnd if the switching between the outdoor and the indoor occurs, the outdoor activity detection result and the previous outdoor activity detection result are different from each other, otherwise, the outdoor activity detection result is inaccurate.
Based on the above theory, the method for determining whether the outdoor activity detection result of the wearable device user is accurate according to the determination result of whether the activity space of the wearable device user in each step counting period is switched may specifically be:
comparing whether the outdoor activity detection result is the same as the previous outdoor activity detection result or not;
if the time T is the same as the previous outdoor activity detection time TcTime T for detecting the outdoor activitylIn one or more step counting periods covered by the time range, if the activity space of the wearable device user is not switched between outdoor and indoor, determining that the outdoor activity detection result of the wearable device user is accurate, otherwise, determining that the outdoor activity detection result of the wearable device user is inaccurate;
if not, if the outdoor activity detection time T of the previous time is differentcTime T for detecting the outdoor activitylIn one or more step counting periods covered by the time range, the activity space of the wearable device user is switched between outdoor and indoor, and then the outdoor activity detection result of the wearable device user is determined to be accurate, otherwise, the outdoor activity detection result of the wearable device user is determined to be inaccurate.
In the embodiment of the present invention shown in fig. 1, the determination of whether the user activity space is switched or not and the determination of the accuracy of the user activity detection result are both performed by the wearable device, however, in practical applications, the wearable device itself is usually smaller and easier to carry, and therefore, the functions are usually simpler, and therefore, these operations may be considered to be performed in the server.
Referring to fig. 2, fig. 2 is a flowchart of a method for improving accuracy of outdoor activity detection according to a second embodiment of the present invention, where the method is applied to a wearable device, and the wearable device is configured with a pedometer, as shown in fig. 1, the method mainly includes the following steps:

Step 202, outdoor activity detection is carried out on the wearable device user, an outdoor activity detection result is sent to the server, a judgment result of the accuracy of the outdoor activity detection result returned by the server according to a judgment result of whether the activity space of the wearable device user is switched in each step counting period is received, and if the judgment result is inaccurate, the outdoor activity detection result of the wearable device user is corrected.
In this embodiment, the determination of whether the user activity space is switched or not is performed by a server, and the wearable device may be connected to the server through a network and perform data communication with the server.
The method for determining whether the activity space of the wearable device user is switched between the outdoor and the indoor in the step counting period according to the step counting data of the wearable device user in the step counting period by the server is the same as the method of the embodiment of the invention shown in fig. 1, and specifically includes: if the step counting data of the wearable device user in the step counting period is larger than a preset step counting threshold value, determining that the activity space of the wearable device user is switched between outdoor and indoor, and otherwise, determining that the activity space of the wearable device user is not switched.
In this embodiment, the determination of the accuracy of the user activity detection result is also performed by the server.
When the wearable device sends the step counting data of the wearable device user in the step counting period to the server, the start and end time of the step counting period also needs to be sent to the server for saving. In addition, when wearable equipment sends the outdoor activities testing result to the server, still need to send this outdoor activities testing time to the server and save.
The method for judging whether the outdoor activity detection result of the wearable device user is accurate or not according to the judgment result of whether the activity space of the wearable device user is switched in each step counting period by the server and the method of the embodiment of the invention shown in fig. 1 specifically comprise the following steps:
