"This monograph thus risks becoming outdated in a very short time since the development of refined sensory substitution systems should allow many of the question raised here to be answered, and some of the conclusions may appear naive to future readers." (BACH Y RITA, 1972) As it turns out, this prediction is far from having been fulfilled: in spite of(More)
In this fundamental study, we compare two scaling methods by focusing on the subjects' strategies which are using a sensory substitution device. Method 1 consists in a reduction of the sensor size and its displacement speed. Here, speed reduction is obtained by a "human" movement reduction (hand speed reduction). Method 2 consists in a classical increase of(More)
In this paper, we propose a formal definition of the perception as a behavioral dynamical attraction basin. The perception is built from the integration of the sensori-motor flow. Psychological considerations and robotic experiments on an embodied " intelligent " system are provided to show how this definition can satisfy both psychologist and robotician(More)
Assessing implicit learning in the continuous pursuit-tracking task usually concerns a repeated segment of target displacements masked by two random segments, as referred to as Pew's paradigm. Evidence for segment learning in this paradigm is scanty and contrasts with robust sequence learning in discrete tracking tasks. The present study investigates this(More)
The strategies of action employed by a human subject in order to perceive simple 2-D forms on the basis of tactile sensory feedback have been modelled by an explicit computer algorithm. The modelling process has been constrained and informed by the capacity of human subjects both to consciously describe their own strategies, and to apply explicit(More)
The goal of this study is to apprehend the perceptive training capacities of a human subject via an artificial device and to also underline their limits and constraints. The principal constraint considered here, is the acuity in other words, the spatial proprieties ratio of the sensor and the explored objects. The experimental device couples the pen of a(More)
When the subjects handle a haptic zoom (kinaesthetic zoom through a sensory substitution device), they don't have any difficulty to make the distinction between a zoom-in and a zoom-out and this, while basing themselves on the number of pins activated under the finger. In a similar way to the visual zoom, the haptic zoom-in gives them access to the detail(More)
With the spread of ICT and the Internet during the last two decades, more and more tools rely on graphical interfaces that make them scarcely accessible to the visually impaired. The ITOIP project aims at developing the use of a tactile perceptual supplementation system called Tactos. A partnership with a visually impaired persons (VIP) association allows(More)
