Introduction: Why spatial computing and AI assistants are the perfect pair today
Over the past few months, the development of models like Liquid AI’s new LFM2.5-24B-A2B and Meta’s recent Muse Wonder has accelerated the convergence betweenspatial computingandAI assistants.These tools are designed to operate directly on devices, offering broader contexts and spatial understanding that traditional LLMs cannot match. Buthowcan we leverage this combination to create truly immersive and contextualized experiences?
The answer is clear: by combining spatial signals (depth, gesture, eye-tracking) with a modern, device-optimized AI assistant, we get an assistant that actswherethe user acts, responding naturally and drastically reducing the need for text-based input.
What is spatial computing and why is it relevant to AI assistants
Spatial computing refers to any technology that interprets and reacts to the position and orientation of the surrounding space. In 2026, it includes:
- Depth sensor fusion (LiDAR, RGB-D, Time-Of-Flight depth sensors)
- Real-time gesture and hand-tracking via edge neural networks
- Eye-gaze and head-pose estimation for contextual focus
- Spatial rendering (light-field, volumetric) for consistent visual feedback
When an AI assistant can access these data streams, it can make smarter decisions: for example, placing a UI element exactly where the user is looking, suggesting actions based on the relationship between the user and the surrounding environment, or navigating three-dimensional spaces more safely.
Key 2026 trends fueling this convergence
Two recent releases exemplify this trend:
- LFM2.5-24B-A2B
- Muse WonderandMuse Wonder Full
Both models supportprompt engineeringspecialized for spatial input, a capability that is expected to become standard for AI assistants in the coming year.
Designing effective prompts for spatial contexts
Creating a prompt for a spatial assistant is not simply writing a question; it requires making context, purpose, and constraints explicit.
Basic prompt template
A reusable template might look like this:
<SYSTEM>\nYou are an AI assistant integrated into a spatial computing system. You receive data streams: depth_map (HxW), gaze_point (x,y), gesture (gesture_id), and the user’s request (user_query). Respond using as few tokens as possible, focusing on spatially contextualized actions.</SYSTEM>\n\n<USER>\nContext: depth_map shows a table at 0.75m distance, gaze_point is at center (0.5,0.5), gesture=PINCH. User: "Place a visual reminder on the object to the left of the table."\n</USER>\n\n<ASSISTANT>\n...</ASSISTANT>This schema ensures that the assistant receives a structured description of the environment, enabling it to map the user’s object onto precise coordinates and generate a UI element that aligns perfectly.
Practical tools: Meta’s Rebalancer API
For those who want to place tasks between on-device and cloud inference, Meta’s Rebalancer API is a key recently released tool. It uses a C++ core with Python bindings to dynamically allocate workloads between local cores and cloud services based on resource availability and latency.
Example code for using Rebalancer with a spatial assistant:
import rebalancer_client
import depth_sensor
import gaze_tracker
# Initialize sensors
depth_stream = depth_sensor.DepthCamera().start()
gaze_stream = gaze_tracker.EyeTracker().start()
# Configure Rebalancer client
client = rebalancer_client.Client(model_id='muse-wonder-full')
while True:
depth = depth_stream.read()
gaze = gaze_stream.read()
# Decide whether to perform inference locally or in the cloud
task = {
'type': 'spatial_reasoning',
'payload': {
'depth': depth,
'gaze': gaze,
'query': user_query
}
}
result = client.dispatch(task)
render_spatial_ui(result)This snippet shows how the assistant can decide in real time whether complex reasoning (e.g., 3D planning) should be sent to Muse Wonder Full, while keeping simpler operations (e.g., UI placement) on the device.
Full example: building a remote collaboration assistant
Imagine two engineers collaborating on a 3D model in real time. The AI assistant should:
- Detect both users’ positions via wearable devices.
- Identify the objects they are talking about using depth mapping.
- Display a shared reminder at the exact point they are looking.
Using LFM2.5-24B-A2B for on-device inference and Muse Wonder for language context enrichment, the workflow would be:
- Acquire depth_map, gaze_point, gesture.
- Create a structured prompt using the template above.
- Send the prompt to LFM2.5-24B-A2B for a quick response (e.g., "Show a blue annotation at (0.3,0.7)").
- If the annotation requires complex rendering, forward a task to Rebalancer for processing with Muse Wonder Full.
- Render the spatially consistent annotation in the 3D viewer.
Key takeaways
- Combining spatial data with modern LLMs(LFM2.5-24B-A2B, Muse Wonder) creates responsive, contextualized assistants.
- Adopt a structured prompt modelthat explicitly includes depth, gaze, and gesture for reliable inference.
- Use Meta Rebalancerto intelligently distribute workloads between edge and cloud.
- Test with real-world use cases(e.g., 3D remote collaboration) to iterate on UI layouts and response times.
- Stay updatedon the latest model releases; the open-weight LFM2.5-24B-A2B and Meta’s new wide-context models are now available for development.
Conclusion: The future is spatial
In 2026, the convergence of spatial computing and AI assistants is no longer a futuristic concept: it is a concrete reality powered by device-optimized models and real-time sensor pipelines. By designing prompts that leverage spatial data and leveraging tools like Meta’s Rebalancer API, developers and product managers can create experiences that adapt to the user’s real-world environment, not a 2D screen. Start today with a structured model, integrate LFM2.5-24B-A2B or Muse Wonder based on your latency needs, and watch as your users interact with truly spatial intelligence.
Bottom line:Use these steps as an operational foundation, adapting tools, policies, and controls to your organization’s real-world context.
