Bluetooth Vehicle Integrated Computer (BVIC)

Today’s roads are becoming increasingly dangerous especially in big cities. Part of this can be attributed to the increased use of cell phones on the road. In fact, the American Automobile Association reports that cell phone usage in vehicles contributes to up to one half of all crashes reported in the US annually.

With the design of BVIC (Bluetooth Vehicle Integrated Computer) many of the safety concerns related to cell phone usage in a car will be eliminated. This system will be fully integrated into a vehicle and will provide user interaction through an LCD touch screen mounted to the vehicle’s dash. Through the use of a custom designed interface, a user can launch three main modules: Bluetooth hands-free service, MP3 player, and Global Positioning System (GPS).

The Bluetooth hands-free service will provide all the features of a standard Bluetooth headset and more. For example, a user will be able to answer/end calls and dial numbers using the touch screen LCD as long as the phone is within the vehicle. Regardless of whether the phone is in a purse or a backpack or under the seat, it can be controlled remotely with the system. The main difference between this system and a regular headset is that the conversation will be broadcasted over the car’s built in audio system.

With the MP3 module, a user will be able to playback all of their favourite music. Supported formats will include MP3, OGG, and WMA. MP3’s stored either locally on the computers hard drive or on an MP3 CD/DVD can be played.

Using the GPS module a user can simply enter their destination address through the touch screen, and a route and set of instructions on how to get to their destination will be generated. A map along with instructions will be given visually through the LCD and audibly through the car stereo. An example instruction would be something like “10 Meters ahead, turn left”. If the user missed a turn, the system would calculate another route on the fly and continue giving instructions.

Although, phone control, MP3, and GPS modules have already been designed for cars, none of the products on the market combine all three into one affordable unit. A car GPS system alone can cost anywhere from $1500 - $3000 depending on installation fees. Furthermore, Bluetooth enabled cars which allow for cell phone pairing are only available in high end luxury cars. BVIC will be both highly useful and affordable to the general public.
