Designing AI presence: why digital humans need a point of view
Marlon on personality, memory and the difference between an assistant and a brand ambassador.
Most AI products are designed to be helpful. Digital humans, in our experience, need to be designed to be someone. That's not the same thing.
When a user opens a chat with a text-only assistant, they have very few cues about who they're talking to. The voice can be neutral. The personality can be a soft hum in the background. With an embodied AI, that's no longer true. Every gesture, every line reading, every micro-expression is a personality choice you're making, whether you intend to or not.
Three things we design for
- A point of view. What does this character believe? What do they care about? An assistant that tries to please everyone reads as hollow on a face. A character with a perspective reads as alive.
- Memory with edges. Remembering a user's name is table stakes. Remembering what they like, what they avoided, what they laughed at. That's where presence lives. So is forgetting the things that aren't theirs to keep.
- Restraint. A digital human doesn't need to fill every silence. The best ones listen. The worst ones perform.
Every avatar we build at Digito starts with a one-page character document before a single polygon moves. It's a small upfront cost that pays back the rest of the production.
