Are you having problems orientating ? ActiveBelt may be your answer
You should consider this as an option if you have problems finding your way. The device is called ActiveBelt and its still a prototype. Since the information given with tactile sense hardly disturbs people’s activities, it is suited for daily use in mobile environment. However, many of existing systems don’t transmit multiple information with tactile sense.

    Most of them send only simple signals, such as vibration of cellular phones. ActiveBelt is a novel belt-type wearable tactile display that can transmit multiple directional information. The directions are transmited trough eight vibrating motors. Let’s hope this gadget will help the people that need it. For more information visit ActiveBelt’s website
