Recent advances in interaction technologies make it possible for people to use freehand gestures in such application domains as virtual reality, augmented reality, ubiquitous computing, and smart rooms. While some applications and systems have been developed to support gesture-based interaction, it is unclear what design processes these systems have(More)
In this paper, we propose least-squares images (LS-images) as a basis for a novel edge-preserving image smoothing method. The LS-image requires the value of each pixel to be a convex linear combination of its neighbors, i.e., to have zero Laplacian, and to approximate the original image in a least-squares sense. The edge-preserving property inherits from(More)
In the design of gesture-based user interfaces, continuously recognizing complex dynamic gestures is a challenging task, because of the high-dimensional information of gestures, ambiguous semantic meanings of gestures, and the presence of unpredictable non-gesture body motions. In this paper, we propose a hybrid model that can leverage the time-series(More)
The “Midas Touch” problem has long been a difficult problem existing in gesture-based interaction. This paper proposes a visual attention-based method to address this problem from the perspective of cognitive psychology. There are three main contributions in this paper: (1) a visual attention-based parallel perception model is constructed by combining(More)
