Understanding how we spontaneously scan the visual world through eye movements is crucial for characterizing both the strategies and inputs of vision. Despite the importance of the third or depth dimension for perception and action, little is known about how the specifically three-dimensional aspects of scenes affect looking behavior. Here we show that(More)
This paper introduces the use of a visual attention model to improve the accuracy of gaze tracking systems. Visual attention models simulate the selective attention part of the human visual system. For instance, in a bottom-up approach, a saliency map is defined for the image and gives an attention weight to every pixel of the image as a function of its(More)
Several studies in affective computing consider the role of haptic channel via the tactile and kinesthetic components. However, these works used constraining haptic devices with limited stimulation strategies. This paper proposes to investigate a new haptic device for the tactile stimulation with a mobile air jet. This approach is more suitable for the(More)
This article introduces a best basis search algorithm in a non-stationary (NS) wavelet packets dictionary. It computes an optimized labeled quad-tree that indexes the filters used for the NS wavelet packets decomposition. This algorithm extends the classical best basis search by exploring in a hierarchical manner all possible NS wavelet packets(More)
Haptic rendering technologies are becoming a strategic component of the new Human-Machines Interfaces. Many existing devices generally operate with intrusive mechanical structures that limit rendering and transparency of the haptic interaction. In the context of the design of a novel non-contact haptic device that exploit the air jet tactile stimulation(More)
Haptic devices are dedicated to render virtual tactile stimulation. A limitation of these devices is the intrusiveness of their mechanical structures, i.e. the user need to hold or wear the device to interact with the environment. Here, we propose a concept of new tactile device named HAIR. The device is composed of a computer vision system, a mechatronic(More)
Nanomanipulation is an important tool for recent developments in nanoscale production, characterization and analysis, both in material and life sciences. Its use is actually limited because of its complexity. Especially inside a scanning electron microscope, kinematic constraints, open-loop actuators and lack of natural visual access are barriers for its(More)
