<aside> 💡 Persimmon Quest is offering a full lifetime package of AI-powered brain computer interface for elderly population around the world. Starting from Japan’s nursing home facilities, because that’s where they need this the most.

PQ is not a single product. Not a one product, two product. But a three product ecosystem.

1. EEG Controller Headband with fNIRS Sensor
2. Nursing Room Tablet with Smart Eye Tracking
3. Edge Computer Hub for Workflow Automation

What problem is PQ solving with these three products ?

How is PQ ecosystem the only solution to this problem ?

How PQ structures a purpose-driven virtual world inside a small nursing home ecosystem that preserves elderly dignity and prioritizes their brain health?

To structure this ecosystem safely, the virtual world acts as a dignified interface that translates raw EEG data into meaningful, therapeutic micro-moments without causing cognitive overload or infantilizing the residents.

Here is how to structure the ecosystem across your proposed layers while maintaining strict clinical ethics, dignity, and the therapeutic Pachinko effect.

1. The Frontend: The Virtual World Framework

The virtual world should not look like a video game; it should feel like an extension of their living space or a dignified "Digital Sanctuary."

• The "Sanctuary" Concept: The core interface can be structured as a Virtual Conservatory or Garden. The health, blooming, and expansion of this garden are directly tied to the user's focus, relaxation, and cognitive exercises.
• The Dignified Pachinko Mechanic: Instead of rapid-fire balls, the user uses focused attention or calm states (via EEG) to gently launch "droplets of light" into the garden. As these droplets bounce through a beautiful, slow-moving geometric grid, they strike nodes that unlock:
  • High-fidelity vintage music streams.
  • Audio messages from family members.
  • Captivating archival historical footage.
• Why it works: It satisfies the brain's craving for variable rewards (unpredictable, beautiful visual/auditory payouts) using dignified, nostalgic content rather than flashing casino lights.

2. The Input Layer: EEG to Action Mapping

Using EEG on an everyday OS requires translating brain waves into explicit, satisfying actions without causing "frustration fatigue."

• Intentional BCI (Brain-Computer Interface) Actions: Avoid complex motor-imagery controls that require intense training. Use binary, high-level states:
  • Focus/Attention (Beta/Gamma waves): Triggers the "launch" or "activation" of an activity.
  • Relaxation/Calm (Alpha waves): Gently navigates or "soothes" elements in the virtual world (e.g., clearing a foggy window to reveal a family photo).
• Graceful Degradation (Hybrid Input): If the EEG sensor experiences high impedance (dislodged by movement) or the resident gets frustrated, the OS must seamlessly blend touch or voice control. The virtual world must never penalize an elder for a weak EEG signal.
