IKEA Virtual Wall (MTI-8)
I built a IKEA Virtual Wall. I used RFID reader and this detects cards on which RFID tags are attached. You scan your cards then the system will show the related item and go to a certain state such as floor-lamp state, book-shelf state and so on. When you are on each state, if you use IR controller, press the button and move it, then the item on the screen will move around accordingly.
Wiimote detects IR led and send data to the computer in real-time via bluetooth(used Processing to get the data). Phidget RFID reader reads the RFID tags and send signal via USB(used Flash to get the data). And I finally used actionscript 3.0 to use the data to design the interface.
