Hot-Drive - Preliminary retrieved POI cognitive driver navigation system

In these days, car navigation is a popular driver assistance system which shows map, and gives route guidance to driver. Normally, navigation is embedded or fixed to car, and gives inconvenient user interface to handle. When a driver is going to go unfamiliar place, looks up the map, and plans driving course before departure. People can easily find the information of POI (Point of interest) and make a driving plan before departure using e-Map. This e-Map can be internet based or standalone software, however usually works on PC. However, if it is long-distance/time traveling or there are many POIs exist, it becomes a burden on driver to remember all. It is also wasteful redundant job to find POI just retrieved on e-Map, but on the car navigation again. Furthermore in traditional navigation, if there are plural destinations, we needed to set each next destination after we get there. We can use external storage card to carry user data, but this requires extra concentration to driver to handle. This paper shows prototype of Hot-Drive system, that user can use custom data transparent to location with short range wireless communication. Evaluated system consists of RF I/F embedded Smart key, Car Navigation and Host PC, which uses 2.4 GHz and 802.15.4 MAC with custom stack. We show an interactive framework sharing a user data between driver and vehicle with less user concentration could be expended to intelligent vehicle with adaptive user interface
