—This paper proposes an algorithm to solve the CEC2013 benchmark. The algorithm, namely Super-fit Multi-criteria Adaptive Differential Evolution (SMADE), is a Memetic Computing approach based on the hybridization of two algo-rithmic schemes according to a super-fit memetic logic. More specifically, the Covariance Matrix Adaptive Evolution Strategy (CMAES),(More)
This paper presents the use of audio and haptic feedbacks to reduce the load of the visual channel in interaction tasks within virtual environments. An examination is made regarding the exploitation of audio and/or haptic cues for the acquisition of a desired target in an environment containing multiple and obscured distractors. This study compares(More)
—The super-fit scheme, consisting of injecting an individual with high fitness into the initial population of an algorithm, has shown to be a simple and effective way to enhance the algorithmic performance of the population-based algorithm. Whether the super-fit individual is based on some prior knowledge on the optimization problem or is derived from an(More)
Individuals with normal hearing are generally able to discriminate auditory stimuli that have the same fundamental frequency but different spectral content. This study concerns to what extent it is possible to perform the same differentiation considering vibratory tactile stimuli. Three perceptual experiments have been carried out in an attempt to compare(More)
This paper addresses the use of audio and haptics as a mean to reduce the load of the visual channel in interaction tasks within virtual environments. An examination is made regarding the exploitation of audio and/or haptic interactions for the acquisition of a target of interest in an environment containing multiple and obscured distractors. A first study(More)
In the last years several solutions were proposed to support people with visual impairments or blindness during road crossing. These solutions focus on computer vision techniques for recognizing pedestrian crosswalks and computing their relative position from the user. Instead, this contribution addresses a different problem; the design of an auditory(More)
This paper presents musical and technological aspects of real-time digital audio processing and visual rendering applied to a grand nineteen-century pipe organ. The organ is " augmented " in both its musical range and visual dimensions, thus increasing its potential for expression. The discussed project was presented to a public audience in the form of(More)
