Abstract. The search for new simplified interaction techniques is mainly motivated by the improvements of the communication with interactive devices. In this paper, we present an interactive TVs module capable of recognizing human gestures through the PS3Eye low-cost camera. We recognize gestures by the tracking of human skin blobs and analyzing the corresponding movements. It provides means to control a TV in an ubiquitous computing environment. We also present a new free gestures icons library created to allow easy representation and diagramming.

Abstract. Besides the emergence of many input devices and sensors, they are still unable to provide good and simple recognition of human postures and gestures. The recognition using simple algorithms implemented on top of these devices (like the Kinect) enlarges use cases for these gestures and postures to newer domains and systems. Our methods cuts the needed computation and allow the integration of other algorithms to run in parallel. We present a system able to track the hand in 3D, log its position and surface information during the time, and recognize hand postures and gestures. We present our solution based on simple geometric algorithms, other tried algorithms, and we discuss some concepts raised from our tests.

International audienceThe goal of HCI researchers is to make interaction with computer interfaces simpler, efficient and more natural. In a context of object manipulation, we think that reaching this goal requires the ability to predict and recognize how humans grasp then manipulate objects. This is based on studies explaining human vision, reach, grasp taxonomies and manipulations. In this paper, we study the full cycle of gesture interaction using different points of view, then attempt to organize them using Norman's theory of Human Action, we link the psychology of object sensing to HCI goals and propose a simplification of gestures classes into four principal families. Our simplification of gestures classes still allow the expression of more detailed subclasses differentiated by the gesture properties

International audienceAlthough UNIX commands are simple, they can be combined to accomplish complex tasks by piping the output of one command, into another's input. With the invasion of GUI applications, we have lost this ability to chain many small tools in order to accomplish a composite task or the possibility to script applications. As such we have become imprisoned into the interface as designed by the developer. Most applications are also designed to be used through a keyboard and a mouse even if the user has newer input devices. In this paper, we demonstrate how we can remove most of these limits and provide the possibility to script, adapt and automate GUI applications using a software bus in a Linux operating system. We provide implemented proof-of-concept cases in addition to conceptual scenarios showing the possibilities arising from the approach
