This project reimagines the nostalgic childhood experience of drawing on a fogged-up mirror by combining physical interaction with digital technology. Users can blow air to create mist on a screen, just as they would on a bathroom mirror, and then use their fingers to draw, erase, or leave marks that fade over time.
The experience goes beyond simple interaction, allowing users to reflect on their emotions or communicate asynchronously with others. The impermanence of the digital drawings mirrors the fleeting nature of childhood memories, making the interaction both playful and introspective. By blending tactile input with visual and temporal feedback, this project offers a meaningful way to connect with personal nostalgia while exploring new forms of self-expression and digital communication.
Through this innovative design, the project invites users to engage in a reflective and sensory experience, bridging the gap between past memories and modern interactive media.
Breath Detection
Blowing Detection: A small speaker-shaped device equipped with a microphone is used to detect the act of blowing air. To ensure accuracy, a low-pass filter is applied, preventing the system from mistaking speech for breath. Only genuine blowing sounds trigger the mist effect on the screen.
Breath Position Tracking: To determine where the user is blowing, the device is fitted with markers tracked by a camera. A hemispherical marker is used to avoid misdetection caused by shadows, ensuring precise position tracking.
Drawing with Fingers
The drawing interaction is achieved through a touch-sensitive screen that detects finger movements. This allows users to erase the mist and create shapes or marks, simulating the nostalgic act of drawing on a fogged-up mirror.
