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 showed the relevance of haptics to convey various types of emotions. This paper proposes to investigate a more suitable tactile stimulation strategy based on mobile air jet which provides a non-intrusive tactile stimulation on different and large areas on the body. Moreover, this tactile strategy allows an efficient simulation of skin(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)
—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)
Smile is an irrefutable expression that shows the physical state of the mind in both true and deceptive ways. Generally, it shows happy state of the mind, however, 'smiles' can be deceptive, for example people can give a smile when they feel happy and sometimes they might also give a smile (in a different way) when they feel pity for others. This work aims(More)
Vection refers to the illusion of self-motion when a significant portion of the visual field is stimulated by visual flow, while body is still. Vection is known to be strong for peripheral vision stimulation and relatively weak for central vision. In this paper, the results of an experimental study of central linear vection with and without vibrotactile(More)
