  The development of computer technology has been rapid. Not so long ago, the
first computer was developed which was large and bulky. Now, the latest
generation of smartphones has a calculation power, which would have been
considered those of supercomputers in 1990. For a smart environment, the person
recognition and re-recognition is an important topic. The distribution of new
technologies like wearable computing is a new approach to the field of person
recognition and re-recognition. This article lays out the idea of identifying
and re-identifying wearable computing devices by listening to their wireless
communication connectivity like Wi-Fi and Bluetooth and building a
classification of interaction scenarios for the combination of
human-wearable-environment.
