Focused Attention
Decoherence Shield
She watches you, so a crowded room can't speak for you.
The world is noisy, and a presence that answers every stray voice is no presence at all. Decoherence Shield gives a digital human focused attention: she attends to one person, fusing what she sees with what she hears so that background voices and ambient noise cannot hijack the conversation.
In a loud space she holds a higher bar, so a person naturally speaks up to be heard — exactly as they would with a real listener across a crowded room. The environment is precisely what would decohere the signal; the Shield holds coherence against it.
The technology
A focus mechanism keeps her attention locked on the person actually speaking to her, so off-camera voices and background chatter can't hijack the conversation — and it adapts on its own to how loud or quiet the space is, with no setup.
Why it matters
Attention is what makes a conversation feel directed at you. Decoherence Shield is the faculty of focus — it is what lets a digital human hold a real exchange in a real, noisy world.
