Inspiration
"Can you hear me now?" We all understand the frustration of struggling to find a signal. Our team experienced this problem while living in a downtown apartment, leading to the envisioning of a solution (eventually called "SeeSignal") that merged together the visualization of live RF signal data with mixed reality. This idea started as a proof-of-concept demo on the Quest 2 and then recently became a viable prototype.
What it does
SeeSignal is a mixed reality app that displays live signal strength as interactive holograms around you. As you move through a space, you can instantly see strong and weak regions and how walls, materials, and objects attenuate or reflect wireless signals. Key features:
- Color-coded signal maps and 3D data grids
- A handheld signal compass for direction-finding
- Wi-Fi painting for granular spatial checks
- "Signal hands" for exploring by touch
How We Built It
We built SeeSignal in Unity 6 targeting Meta Quest 2/3/3S/Pro using a combination of platform APIs and custom systems:
- Meta Horizon APIs for spatial anchors, room understanding, and passthrough compositing
- Device-level Wi-Fi scanning via system interfaces to retrieve RSSI/SNR samples at a controllable cadence
- Unity's XR Hands subsystem for natural gesture input
- Room Meshing utilities to align holograms with real-world geometry
- Suite of interactive "gadget" tools to scan, inspect, and analyze signals
- Embedded AI models for 4D radio signal spatial propagation
- Custom shaders for high-performance rendering
Challenges We Ran Into
- Accurate data: Signals change fast, so we smoothed readings and estimated strength across space using homemade models.
- Simple XR controls: Natural hand interfaces are difficult to design for but make the experience much more intuitive.
- Colors (or lack thereof): Not everyone can see all the colors of the spectrum! We forgot this. One of our color-blind teammates kindly reminded us, so we added an option to change the color palette.
Accomplishments We're Proud Of
- Made live RF data easy for anyone to understand
- Enabled direction-finding to strongest (or weakest) signal points
- Developed new immersive design patterns that will help pioneer the future of XR
- Integrated natural hand tracking and gestures, allowing fully hands-free usage requested by potential customers
What We've Learned
- Insightful spatial tools beat raw data overlays
- Giving users control over when and where scanning occurs increases engagement
- Mixed reality UX requires careful tuning of motion, latency, and depth cues to avoid discomfort
- Meta Horizon is an extremely capable platform for next-generation user experiences
What's Next for SeeSignal
Wireless connectivity is critical, yet few tools make it easy to see or analyze in real time. SeeSignal helps people optimize router placement, diagnose dead zones, and deploy networks more effectively. Key use cases include commercial networking, telecom troubleshooting, and RF bug-hunting. Next steps include UI polish, onboarding, and marketing capture ahead of store launch.
