Method for estimating user's moving distance and wearable distance estimating device

Abstract

A method for estimating a user's moving distance, suitable for a wearable distance estimation device, the device includes an acceleration sensor, a positioning unit, and a processor, the positioning unit is in an activated state and a non-activated state During operation, the method includes: (A) the acceleration sensor senses the user's stride frequency; (B) during the duty cycle, the positioning unit generates the user's positioning information; (C) during the duty cycle, according to the The generated positioning information estimates a first displacement, and during the non-duty period, estimates a second displacement based on a sensed current stride, a reference step distance of the user and the duration of the non-duty period and (D) the processor sums the estimated first displacement and the second displacement to obtain the moving distance of the user.

Description

technical field [0001] The present invention relates to an estimating method and an estimating device, in particular to a method for estimating a user's moving distance and a wearable distance estimating device. Background technique [0002] The 2014 Standard Chartered International Marathon gathered more than 30,000 people to start, and the 2014 Kaohsiung International Marathon also attracted 35,000 people to participate in the event. The number of people participating in the marathon is increasing year by year. With the vigorous promotion of the government and the completion of various public facilities, jogging has become a national sport. [0003] Wearable devices, such as navigation watches, have also become the new darling of related products in this wave of boom. The convenience of wearable devices that can receive and provide information to users in real time has aroused users' desire to buy. Although it is not yet the case of one person, according to this year's CE...

Problems solved by technology

The current solution is to reduce the time when the GPS positioning unit is turned on. For example, there are ten GPS positioning data in ten seconds, that is, one positioning point is generated every second, which is reduced to one positioning point every two seconds, so as to achieve power saving. As a result, the original ten positioning points are reduced to five. Although the power is saved, the estimated path length becomes inaccurate due to the reduced resolution.
