Option 2
Projection-Based Interaction
Fan-like Texture
All Arduino sensing components were pre-tested to ensure stable performance. This was crucial for a reliable experience once the installation was complete.
2. Preparing the Frame
A wooden picture frame was used as the base. Arduino modules were planned to be installed behind the backboard to keep the surface flat and clean.
3. Thinning the Backboard
To improve sensor responsiveness, the backboard was sanded down in specific areas. This allowed the sensing modules to function accurately through the material.
4. Applying Fan Fabric
Traditional tuanshan（round fan） cloth was stretched across the surface to mimic the texture and appearance of hand fans. It also diffused light from the projection naturally.
5. Color Matching Finish
The picture frame was spray-painted to match the fan handle’s tone, creating a unified appearance.
5. Assembly
The thinned wooden frame, sensing units, and fabric were assembled into a single piece. From the outside, it appeared handmade and analog—while housing a hidden interactive system.
6. Abandoning the Setup
Due to limitations at the exhibition site—including excessive lighting and lack of mounting options for the projector—the projection setup had to be discontinued. The project proceeded with the screen-based version instead.
7. Repurposed for Participation
Although this setup was ultimately not used for interaction, it was transformed into a participatory station where visitors co-created painted fans together during the exhibition.
