abstract = {In this paper, we introduce a novel method for view-independent hand pose recognition from depth data. The proposed approach, which does not rely on color information, provides an estimation of the shape and orientation of the user's hand without constraining him/her to maintain a fixed position in the 3D space. We use principal component analysis to estimate the hand orientation in space, Flusser moment invariants as image features and two SVM-RBF classifiers for visual recognition. Moreover, we describe a novel weighting method that takes advantage of the orientation and velocity of the user's hand to assign a score to each hand shape hypothesis. The complete processing chain is described and evaluated in terms of real-time performance and classification accuracy. As a case study, it has also been integrated into a touchless interface for 3D medical visualization, which allows users to manipulate 3D anatomical parts with up to six degrees of freedom. Furthermore, the paper discusses the results of a user study aimed at assessing if using hand velocity as an indicator of the user's intentionality in changing hand posture results in an overall gain in the classification accuracy. The experimental results show that, especially in the presence of out-of-plane rotations of the hand, the introduction of the velocity-based weighting method produces a significant increase in the pose recognition accuracy.},

abstract = {During the last few years, we have been witnessing a widespread adoption of touchless technologies in the context of surgical procedures. Touchless interfaces are advantageous in that they can preserve sterility around the patient, allowing surgeons to visualize medical images without having to physically touch any control or to rely on a proxy. Such interfaces have been tailored to interact with 2D medical images but not with 3D reconstructions of anatomical data, since such an interaction requires at least three degrees of freedom. In this paper, we discuss the results of a user study in which a mouse-based interface has been compared with two Kinect-based touchless interfaces which allow users to interact with 3D data with up to nine degrees of freedom. The experimental results show that there is a significant relation between the number of degrees of freedom simultaneously controlled by the user and the number of degrees of freedom required to perform, in a touchless way, an accurate manipulation task.},
