Technology

Physical AI you can feel.

NextGuide brings the perception and decision-making of intelligent machines into the handle of a white cane, and communicates what it understands through touch.

The loop

From pixels to a pointer under your thumb.

NextGuide continuously runs a closed loop from perception to guidance, entirely inside the handle.

01

Perceive

A forward-facing camera in the handle captures the scene in front of the user, well beyond the reach of the cane tip.

  • Continuous view of the path ahead
  • Sees obstacles before the cane touches them
  • Designed for indoor and outdoor environments
02

Understand

Multimodal AI turns raw images into an understanding of the scene: what is free space, what is in the way, and what matters for getting somewhere.

  • Obstacles, doors, crosswalks and stairs
  • Free, walkable space, even without tactile edges
  • Context, not just distance
03

Plan

A learned navigation model, built on principles from robotics, decides on a safe direction through the scene and updates it continuously as the user moves.

  • Real-time path planning around obstacles
  • Keeps the user centred on paths without edges
  • Smooth, predictable guidance
04

Guide

The plan becomes touch. A tactile pointer under the thumb shows the direction to walk, and distinct vibration patterns signal what is ahead.

  • Silent, intuitive direction under the thumb
  • Distinct cues for doors, crossings and stairs
  • Leaves hearing free for the environment

Demos

Tested indoors and outdoors.

Principles

Built for the real world.

On-device by design

Fast, private and offline.

All AI runs on a dedicated processor inside the handle. No cloud, no smartphone and no network connection are needed, so guidance stays fast and camera images never leave the device.

Human in the loop

It guides. You decide.

NextGuide suggests a direction and lets the user feel it. It never takes over. The cane remains a cane, so users keep the technique and feedback they already rely on.

Hardware

Everything in the handle.

Smart handle

Camera, AI processor, haptics and battery in one ergonomic grip.

Origins

Engineered at ETH Zurich.

NextGuide grew out of engineering work at ETH Zurich and was presented as part of CYBATHLON at REHACARE. Today it is a working research prototype.

The next stage is turning the prototype into a certified medical device, built to the standards of safety-critical engineering.
