Background

Climbing progression relies on proprioception and reading beta that isn’t always obvious when you’re alone on the wall. ABC blends embedded hardware and coaching logic so climbers keep learning by climbing, not by switching to a laptop tutorial.

RGB LEDs + capacitive sensors transform each modular hold into a learning node: they light up to suggest sequences, collect time-on-hold data, and react when the climber hesitates.

Research & insight synthesis

We shadowed lessons, logged interviews, and mapped the tension between climbers needing hints when stuck and gym owners needing faster ways to refresh problems. Those insights shaped both the augmented holds and the operating system behind them.

Brief distilled

Focus on indoor bouldering, build a customizable physical-digital path that improves body position and grip choices for intermediate climbers, and ensure the experience can be refreshed without rebolting the entire wall.

The resulting experience mixes analog holds with augmented cues: LED segments pulse to suggest sequences, while sensors capture data for coaches.

Project brief summary

System architecture

Each hold is a module: translucent PU windows reveal LED guidance, capacitive sensors log grip quality, and the 360° collar channels both power and data. NFC tags let the system know exactly which hold sits where.

Hardware details

The T-nut bolt keeps compatibility with existing walls while a rotating ring locks the smart interface. Sensors detect hand placement and dwell time; NFC anchor points ensure the software understands the wall topology.

Digital companion

The ABC app combines route selection, live guidance, and post-session analytics. Climbers can request hints mid-route, while coaches push curated drills. The UI intentionally echoes analog route cards with layered data.

Climbing experience prototype

Unity drove the LED choreography and sensor visualizations on a physical wall, letting us test adaptive coaching moments with climbers. The video below captures the interaction loop.

Physical prototype & outcomes

We machined the modular holds, cast translucent PU windows, and wired the electronics for on-wall testing. The pilot demonstrated how data-informed holds can keep climbers progressing and created a template for future smart wall deployments.
