SECTION 03 // SYSTEM DESIGN & IMPLEMENTATION

Masko consists of a tangible, sensor-based interface connected to an XR environment. Embedded heart-rate and movement sensing translate physiological and bodily states into subtle atmospheric changes rather than direct commands.

The UI-free system keeps attention on touch, movement and interpretation. Its deliberately delayed responses frame biofeedback as a reflective encounter instead of a metric to monitor or optimise.

INPUT
Embedded Heart Rate & Movement Sensors (Microcontroller)
TRANSMISSION
Wireless Low-Latency Streaming
ENVIRONMENT
Unity-Based Atmospheric XR (Non-figurative, UI-free)

SECTION 04 // FINDINGS & LESSONS LEARNED

01 // AMBIGUITY

Enabled imaginative engagement, but caused orientation challenges.

02 // EMBODIMENT

Delayed biofeedback supported reflective, somatic interaction.

03 // NARRATIVE

Increased emotional resonance without prescribing behavior.
