Geometrical intuitions spontaneously drive visuo-spatial reasoning in human adults,
children and animals. Is their emergence intrinsically linked to visual experience, or does it …

Since the early phenomenological demonstrations of Gestalt principles, one of the major
challenges of Gestalt psychology has been to quantify these principles. Here, we show that …

The counting process can only be fully understood when taking into account the visual
characteristics of the sets counted. Comparing behavioral data as well as event-related …

Electrotactile stimulation through matrix electrodes is a promising technology to restore high-
resolution tactile feedback in extended reality applications. One of the fundamental tactile …

Perceptual grouping, a fundamental mechanism in our visual system, significantly influences
our interpretation of and interaction with the surrounding world. This study explores the …

In recent years a growing interest has emerged in numerosity perception in touch. Most of
the studies on tactile numerosity perception have investigated its spatial aspect by testing …

This research investigated several haptic interfaces designed to reduce mistakes in Morse
code reception. Results concluded that a bimanual setup, discriminating dots/dashes by …

Spatial arrangement is known to influence enumeration times in vision. In haptic
enumeration, it has been shown that dividing the total number of items over the two hands …

We investigated grouping by similarity of surface roughness in the context of task difficulty.
We hypothesized that grouping yields a larger benefit at higher levels of task complexity …

Behavioral and neurophysiological findings in vision suggest that perceptual grouping is not
a unitary process and that different grouping principles have different processing …
