Reconfigurable In-Vehicle Infrared Interface

Re-configurable IR Based User Interface for Vehicles

Design Overview

• Mica2dot (from CrossBow) with IR transreceiver
• Mica2dot: 4Mhz Atmel, 4 kB of RAM, 128kB code space, a 433 MHz ISM Band radio, 50kb/s
• Even driven; disruption of IR reception triggers event at the receiver mote.  
• TinyOS as the s/w platform
• Minimal wiring, except for external power if needed
• Motes still communicate via RF
• Multihop network of motes; utility of the system can be increased by placing other motes in the vehicle. 

Advantages

• Can be relocated to any location based on user preference e.g. Front Windshield 
• Minimal Wiring
• Ease of Use 

Open Items

• Resolution of the Arrays required 
• Visualization of the UI 
• Temperature sensitivity of the IR communication 
• Is it possible to get the Push button functionality with this system
