  • Data distribution through an Android application

  • Wear OS visualization on a smartwatch with custom UI for live feedback

An alternative, mobile-only implementation will also be considered to eliminate the PC dependency.

Research Goals

  • Demonstrate feasibility of BCI-smartwatch integration

  • Evaluate user experience and interface design for biometric feedback

  • Benchmark system latency and reliability

  • Explore applications in meditation, sleep analysis, focus training, and cognitive load assessment.

Expected Outcomes
