Do goal cue and motor activity impact preschoolers’ working memory?

Fitamen, Christophe ; Blaye, Agnès ; Camos, Valérie

In: British Journal of Developmental Psychology, 2021, p. 1-16

Preschoolers are well known for their poor working memory (WM) performance. This could result from goal neglect, which would hamper the setting of maintenance strategies. Previous studies have shown that preschoolers’ WM performance can be improved in game-like tasks, because they provide cues to support goal maintenance. However, in these studies, it was unclear what features of the task...

Perception-aware computational fabrication : increasing the apparent gamut of digital fabrication

Piovarči, Michal ; Didyk, Piotr (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO015.

Haptic and visual feedback are important for assessing objects' quality and affordance. One of the benefits of additive manufacturing is that it enables the creation of objects with personalized tactile and visual properties. This personalization is realized by the ability to deposit functionally graded materials at microscopic resolution. However, faithfully reproducing real-world objects on a...

Reducing simulator sickness with perceptual camera control

Hu, Ping ; Sun, Qi ; Didyk, Piotr ; Wei, Li-Yi ; Kaufman, Arie E.

In: ACM transactions on graphics, 2020, vol. 38, no. 6, p. 15 p

Virtual-reality provides an immersive environment but can induce cybersickness due to the discrepancy between visual and vestibular cues. To avoid this problem, the movement of the virtual camera needs to match the motion of the user in the real world. Unfortunately, this is usually difficult due to the mismatch between the size of the virtual environments and the space available to the users...

Fabrication-in-the-loop co-optimization of surfaces and styli for drawing haptics

Piovarči, Michal ; Kaufman, Danny M. ; Levin, David I. W. ; Didyk, Piotr

In: ACM transactions on graphics, 2020, vol. 39, no. 4, p. 16 p

Digital drawing tools are now standard in art and design workflows. These tools offer comfort, portability, and precision as well as native integration with digital-art workflows, software, and tools. At the same time, artists continue to work with long-standing, traditional drawing tools. One feature of traditional tools, well-appreciated by many artists and lacking in digital tools, is the...

A biologically-inspired model to predict perceived visual speed as a function of the stimulated portion of the visual field

Solari, Fabio ; Caramenti, Martina ; Chessa, Manuela ; Pretto, Paolo ; Bülthoff, Heinrich H. ; Bresciani, Jean-Pierre

In: Frontiers in Neural Circuits, 2019, vol. 13, p. -

Spatial orientation relies on a representation of the position and orientation of the body relative to the surrounding environment. When navigating in the environment, this representation must be constantly updated taking into account the direction, speed, and amplitude of body motion. Visual information plays an important role in this updating process, notably via optical flow. Here, we...
