Conferring human action recognition skills to life-like agents

TLDR: A model of human actions along with a real - time recognition system for human action recognition is presented and a motion management library is described that solves animation continuity and mixing problems.

Abstract: Most of today's virtual environments are populated with some kind of autonomous life - like agents . Such agents follow a preprogrammed sequence of behaviors that excludes the user as a participating entity in the virtual society . In order to make inhabited virtual reality an attractive place for information exchange and social interaction , we need to equip the autonomous agents with some perception and interpretation skills . In this paper we present one skill: human action recognition . By opposition to human - computer interfaces that focus on speech or hand gestures , we propose a full - body integration of the user . We present a model of human actions along with a real - time recognition system . To cover the bilateral aspect in human - computer interfaces , we also discuss some action response issues . In particular , we describe a motion management library that solves animation continuity and mixing problems . Finally , we illustrate our systemwith two examples and discuss what we have learned .
