CONVERSATIONAL METAHUMAN

A life-size photorealistic MetaHuman that listens, answers out loud in character, and lip-syncs in real time. Built as personal R&D against one hard constraint: it has to run all day, unattended, with nobody there to restart it.

FIG.01 — the avatar answering a spoken question
01

The idea

[ SEC 01 / 04 ]

Someone walks up to a screen and asks a question — out loud or by typing — and a life-size, photorealistic figure answers aloud, in character, with its face and body moving in time with its voice.

Built as personal R&D around one demanding brief: it has to run all day in a public space, with no operator and nobody there to restart it.

02

The challenge

[ SEC 02 / 04 ]
  1. 01

    Feel instant

    A silent, staring figure reads as broken. It starts speaking in about two seconds — quick enough that the pause reads as thinking, not failure.

  2. 02

    Stay truthful

    It answers from a curated body of knowledge, and when it doesn't know, it says so. An honest "I don't know" beats a confident wrong answer.

  3. 03

    Never break in public

    No error screens, no frozen faces. If anything behind the scenes stops, the figure settles calmly and the visitor sees nothing alarming.

03

What made it hard

[ SEC 03 / 04 ]

A digital human looks alive in the small moments, not the big ones — a blink that lands naturally, gestures that fit the length of a sentence, a body that keeps breathing while it listens. Each was tuned by watching the character answer real questions.

The hardest problems disguised themselves as something else: what looked like one fault was usually two, quietly cancelling each other out. They were solved by measuring what actually happened, not by trusting the most plausible explanation.

04

The result

[ SEC 04 / 04 ]

A self-running kiosk that holds a spoken conversation in character, keeps its composure when something goes wrong, and needs no one to look after it — built end to end, from the character to the screen the visitor sees.

Happy to walk through it in person.
