Real-time crowd labeling for deployable activity recognition

Systems that automatically recognize human activities offer the potential of timely, task-relevant information and support.

In this paper, we introduce Legion:AR, a system that provides robust, deployable activity recognition by supplementing existing recognition systems with on-demand, real-time activity identification using input from the crowd.

Legion:AR uses activity labels collected from crowd workers to train an automatic activity recognition system online to automatically recognize future occurrences.
