It is based on Interactive-Wear’s ‘Know-where concept Jacket‘
with their integrated MP3 player and a Bluetooth mobile phone
interface. Thats basically the ’standard’ configuration for
a decent Wearable Electronic Jacket (and yes, we still don’t
like the integrated MP3 player).

The additional bonus for the io-Jacket is the use of the
GPSoverIP function from a German company with the same name.
This technology is used to track the movement of trucks of
transportation and delivery companies. The GPSoverIP has also
the possibility to ’see’ inside buildings where normal GPS
does not work. Pretty nice feature. With the service from
Vodafone, the Jacket (wearer) can upload in realtime the
data (position) and anyone knowing the website can follow
in realtime the movement.
