Abstract: A system for labeling motion data includes a memory and a processor. The memory stores instructions. The processor accesses and executes the instructions to perform the following: generate a motion trajectory passage, which includes an initial posture; access unlabeled motion data; determine whether the unlabeled motion data includes the initial posture; in response to the unlabeled motion data including the initial posture, determine whether the unlabeled motion data matches the motion trajectory passage; and in response to the unlabeled motion data matching the motion trajectory passage, attach a label to the unlabeled motion data.

Abstract: A data filtering device stores a piece of standard track data and a piece of target track data. The piece of standard track data corresponds to a standard track in a six degree-of-freedom (DoF) virtual space constructed by a plurality of virtual space units, and the piece of target track data corresponds to a target track in the six-DoF space. The data filtering device determines whether a degree of similarity between the standard track and the target track is lower than a threshold of similarity. When determining that the degree of similarity is lower than the threshold of similarity, the data filtering device classifies the piece of target track data as an invalid data.

Abstract: A mobile navigation system includes positioning devices and a positioning datasheet generating unit. The positioning devices are installed in multiple areas and transmit wireless signals containing positioning device serial numbers. The positioning datasheet generating unit provides an electronic region map and a positioning datasheet to a mobile device. The positioning datasheet includes location information of the areas, the associated positioning device serial numbers, and navigation routes between any two of the areas. The mobile device searches the positioning datasheet to obtain the location information of a current area of itself with the positioning device serial number in the wireless signal received from the positioning device. The mobile device displays the current area on the electronic region map. Upon receiving a destination area, the mobile device searches the positioning datasheet to find a navigation route between the current area and the destination area and displays the navigation route.
