Query: Predicting Human Intentions from Motion Only: A 2D+3D Fusion Approach   In this paper, we address the new problem of the prediction of human intents.
There is neuro-psychological evidence that actions performed by humans are
anticipated by peculiar motor acts which are discriminant of the type of action
going to be performed afterwards. In other words, an actual intent can be
forecast by looking at the kinematics of the immediately preceding movement. To
prove it in a computational and quantitative manner, we devise a new
experimental setup where, without using contextual information, we predict
human intents all originating from the same motor act. We posit the problem as
a classification task and we introduce a new multi-modal dataset consisting of
a set of motion capture marker 3D data and 2D video sequences, where, by only
analysing very similar movements in both training and test phases, we are able
to predict the underlying intent, i.e., the future, never observed action. We
also present an extensive experimental evaluation as a baseline, customizing
state-of-the-art techniques for either 3D and 2D data analysis. Realizing that
video processing methods lead to inferior performance but show complementary
information with respect to 3D data sequences, we developed a 2D+3D fusion
analysis where we achieve better classification accuracies, attesting the
superiority of the multimodal approach for the context-free prediction of human
intents.
