AI Spatial Computing Assistant Powered by Spline AI

An AI Spatial Computing Assistant powered by Spline AI is essentially a 3D interactive environment where an AI agent can see, react, and control objects inside a spatial scene (web, XR, AR/VR, Vision Pro, mobile). It combines:

• 3D scene engine
• AI interface (voice or text)
• interaction logic / variables
• real-time APIs

This lets users interact with a 3D world using natural language or voice commands.

1. Architecture of a Spline AI Spatial Assistant

Typical production stack:

User (voice / cursor / gesture)
        ↓
AI Interface (OpenAI / Realtime API)
        ↓
Spline AI Voice Assistant
        ↓
Variables + Events + Triggers
        ↓
3D Scene Actions
(position / animation / camera / UI)
        ↓
External APIs (weather, CRM, database)

Spline scenes can be embedded in web apps or exported to iOS, Android, or spatial devices like VisionOS.

Step 1 — Create a Spline Scene

Platform:

• Spline

Basic scene:

Scene
 ├─ AI Avatar (3D model)
 ├─ Interactive objects
 ├─ Camera
 └─ UI elements

Typical objects:

• avatar / assistant
• floating panels
• holographic UI
• interactive buttons
• spatial widgets

Step 2 — Enable AI Assistant

Spline has a built-in AI Voice Assistant API.

Setup:

Variables Panel
 → +
 → AI Voice Assistant

This enables:

• microphone input
• real-time voice responses
• AI triggered actions in scene

The assistant uses OpenAI realtime APIs to stream responses and drive scene behavior.

Step 3 — Create Variables (Spatial State)

Variables control objects.

Examples:

userIntent
avatarEmotion
objectPosition
panelVisible
voiceSpectrum

Use variables to bind:

AI input → scene state

Example:

"show dashboard"
→ panelVisible = true

Step 4 — AI Trigger Events

Spline provides AI Assistant Trigger Events.

Example trigger:

Trigger description:
"open analytics dashboard"

Action:

switch camera
show panel
animate objects
play sound

The AI maps natural language → trigger automatically.

3. Advanced Spatial Interaction Logic

Example: AI moving objects

User:

"Move the cube to the left"

Trigger:

move cube

Action pipeline:

AI Trigger
 → Set Variable
 → Object Position = X - 200

Example: Spatial UI assistant

User:

"Show my calendar here"

Scene action:

spawn UI panel
attach to camera anchor
load calendar API

4. AI + Scene Animation (Voice Driven)

Spline exposes voice spectrum data.

This allows:

voice → animation

Examples:

| Input           | Scene effect   |
| --------------- | -------------- |
| voice amplitude | avatar mouth   |
| pitch           | color glow     |
| speech          | particle waves |

The system reads frequency values and maps them to object properties.

5. External AI Brain (Advanced Setup)

Real projects usually connect Spline with backend AI.

Example stack:

Frontend
  React + Spline viewer

Backend
  Node.js

AI
  OpenAI / LLM

Data
  APIs / database

Flow:

User voice
 → AI
 → intent detection
 → webhook
 → Spline variable update
 → scene reacts

6. Spatial Computing Features You Can Add

1️⃣ Spatial command system

Example commands:

"Put weather panel on the right"
"Zoom into the model"
"Highlight object"

2️⃣ AI avatars

Use animated assistant:

AI → emotion variable

Examples:

happy
thinking
processing
explaining

3️⃣ Context awareness

Use camera position:

user distance
gaze direction
hover events

4️⃣ Real-time data panels

finance dashboard
IoT controls
smart home UI
AI copilots

7. Example Real Use Cases

AI spatial dashboard

3D data visualization
AI explains charts

Spatial knowledge assistant

museum guide
education
training simulations

Product configurator

AI explains product
changes materials
shows exploded view

XR workspace assistant

AI places windows in 3D

8. Advanced Options (Pro Level)

AI + Webhooks

Trigger events from external systems.

Example:

stock price change
→ update chart in scene

Multi-agent scenes

Example:

assistant
data agent
navigation agent

Procedural 3D generation

Use Spline AI:

prompt → generate 3D object

Example:

"Create a futuristic drone"

Spline AI generates the model or texture automatically.
