SOLUTION · AI DIGITAL HUMAN SIGNAGE

AI Digital Human Interactive Signage

You already own the screens and the playback system. We build the digital human, optimise it to render locally on our hardware, and connect it to the signage system you run today.

Custom avatars On-device rendering Signage integration Build once, own it forever
A shopper walks up, it says hello. A shopper asks, it answers.
TRY IT LIVE

Talk to the digital human right here

Open this page on a phone or a computer, tap the microphone and speak to the avatar directly — the same system that runs on the signage screens.

WHAT IT IS

Keep your screens. Turn your existing signage into a brand new AI signage system

We build your 3D or 2D digital human, render the model locally on our hardware, and connect the back end to your own content and advertising system. A shopper walks up, it says hello. A shopper asks, it answers.

HOW IT WORKS

Three steps from ad screen to AI screen

STEP 01
Plug in the AI hardware
Straight into the screen's HDMI port, powered over Type-C. Your existing player stays untouched.
STEP 02
Connect your back end
We integrate with your content and ad system. Creative, scheduling and scripts stay in your hands.
STEP 03
The avatar starts serving
It greets people who walk up and answers when they speak. Broadcast becomes conversation.
WHY THIS WAY

No expensive subscription. Build once, use it forever.

COST
Build once, own it forever
The avatar model is delivered to you and it is yours. No monthly fee, no per-interaction billing.
RENDERING
Real-time, on the device
The avatar runs inside the hardware, not in the cloud. Fast to respond, no stutter.
RETROFIT
No screens to replace
Any screen with HDMI can be upgraded. Add it site by site across the estate you already run.
OWNERSHIP
Character and scripts stay yours
Model, creative and knowledge base belong to you. New campaign, new back-end content.
We provide custom digital human production plus the optimisation and playback layer built on our own AI TV stick.
CUSTOM AVATAR

We build your digital human, 3D or 2D

Brand character / real-person likeness / original IP
3D DIGITAL HUMAN
Full body, turns and moves in space
Modelling, rigging, facial expression and lip sync, idle poses and gestures — the full build. Best for brand ambassadors, sales assistants and greeters.
2D DIGITAL HUMAN
Faster to build, lower cost, half body
Illustrated or photoreal, driven by lip sync and expression. Best for announcements, in-store Q&A and event wayfinding.
Look & wardrobe Voice & pacing Personality & scripts Multilingual voiceover Scene background & framing
INTERACTION

Someone walks up and it goes to work

01
Greets on approach
Senses someone nearby and switches from standby to a spoken hello.
02
Voice Q&A
People just talk. The avatar understands and answers out loud.
03
Answers real questions
Price, promotions, directions, stock, how to apply — all from your knowledge base.
04
Guides the next step
Recommends the current campaign, points the way, offers a QR coupon — attention captured.
Empty in front of the screen: back to the ad loop. Someone there: interactive. One screen, two modes.
SYSTEM INTEGRATION

Connected to your content and ad system

What the avatar says and plays is decided by the systems you already run. Our job is to plug into them, not to make you switch.

Creative & scheduling: keep your existing CMS and player
Knowledge base: import products, prices, promotions, store info
Business systems: API hooks for membership, stock, queueing, applications
Data back: interaction counts, top questions and leads return to your back end

COST STRUCTURE

How this differs from cloud subscriptions

SUBSCRIPTION CLOUD
Monthly fees, billed by the minute
Your character and model live on their platform
The more people interact, the bigger the bill
Frames come from the cloud — network drops, screen stops
Stop paying and the avatar is gone
OUR APPROACH
Build once, use it forever
The model is delivered to you and installed on your own devices
No extra charge however many interactions you get
Local rendering keeps the picture up on a weak connection
Each new site is one more stick — low marginal cost
Pricing is made of three parts: avatar production (one-off) + hardware (per site) + optional integration and knowledge-base setup.
DELIVERY

From signing off the character to going live

01 · CHARACTER
Sign off the avatar
You send brand assets or a reference look. We come back with 2D / 3D concepts and voice samples.
02 · PRODUCTION
Model & optimise
Modelling, rigging, motion and lip sync, then compressed to run in real time on the hardware.
03 · INTEGRATION
Back end & knowledge base
We connect your ad and content systems, import the Q&A material and set the interaction scripts.
04 · ROLLOUT
Pilot, then scale
Prove it at one site, then add hardware screen by screen to replicate it.
