A maintenance engineer who talks to pumps and pipes may not seem like the ideal person to entrust with keeping a factory running smoothly, but we hope that our mobile speech-enabled augmented reality (SEAR) framework will enable such behavior in the future to be anything but suspicious. We describe how the SEAR framework uses our flexible and scalable vision-based localization techniques to offer the engineer a seamless multi-modal user interface. This interface juxtaposes a graphical augmented reality view with a context-sensitive speech dialog concerning the industrial equipment located in the immediate vicinity.
