Earphone Style Wearable Device for Automatic Guidance Service with Position Sensing

This paper describes a design of earphone style
wearable device that may provide an automatic guidance service for
visitors. With both position information and orientation information
obtained from NFC and terrestrial magnetism sensor, a high level
automatic guide service may be realized. To realize the service, a
algorithm for position detection using the packet from NFC tags, and
developed an algorithm to calculate the device orientation based on
the data from acceleration and terrestrial magnetism sensors called as
MEMS. If visitors want to know some explanation about an exhibit
in front of him, what he has to do is only move to the object and
stands for a moment. The identification program will automatically
recognize the status based on the information from NFC and MEMS,
and start playing explanation content about the exhibit. This service
should be useful for improving the understanding of the exhibition
items and bring more satisfactory visiting experience without less
burden.
