Fan with NFC tag inside
Reader module discreetly placed under the fan frame
NFC-Based Interaction
The core technology of this installation is NFC (Near Field Communication).
Each fan contains a built-in IC chip (NFC tag) with a unique ID.
When the fan is brought within 5 cm of the RC522 NFC reader embedded behind the projection screen, the reader communicates with the tag at 13.56 MHz, detecting its ID.
The RC522 module sends this information to the Arduino board, which then communicates with Processing to trigger a corresponding video.
Functionality Test
A minimal setup was used to conduct the final test of hardware and code before full assembly and decoration.
The test verified whether each of the four NFC tags could correctly trigger its corresponding video content.
The influence of the arc-shaped receiver frame on interaction accuracy and usability was also examined.
Various tag placements on the fan were tested to determine the most effective position—balancing both the natural fanning motion of participants and reliable activation within the NFC range.
