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...

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...

Human-robot interaction with pointing gestures : intuitive interaction between co-located humans and robots

Gromov, Boris ; Gambardella, Luca Maria (Dir.) ; Giusti, Alessandro (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020INFO004.

Human-robot interaction (HRI) is an active area of research and an essential component for the effective integration of mobile robots in everyday environments. In this PhD work, we studied, designed, implemented, and experimentally validated new efficient interaction modalities between humans and robots that share the same workspace. The core of the work revolves around deictic (pointing)...

Experiential learning under ambiguity

Wahle, Thorsten ; Martignoni, Dirk (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO003.

In this dissertation I study choice contexts of learning under ambiguity. Experiential learning takes place by making choices, observing the outcomes, and altering future choices accordingly. Over time, such learning is expected to improve choices and outcomes but only when decision makers can classify outcomes as either successes or failures. This dichotomous outcome has clear behavioral...

Regular physical activity modulates perceived visual speed when running in treadmill-mediated virtual environments

Caramenti, Martina ; Lafortuna, Claudio L. ; Mugellini, Elena ; Khaled, Omar Abou ; Bresciani, Jean-Pierre ; Dubois, Amandine

In: PLOS ONE, 2019, vol. 14, no. 6, p. e0219017

In virtual reality, visual speed is usually underestimated relative to locomotor speed. Here we investigated how physical activity and fitness affect perceived visual speed when running in a treadmill-mediated virtual environment. Thirty healthy participants (ten sedentary individuals, ten team sport players and ten expert runners) ran on a treadmill at two different speeds (8, 12km/h) in...

3D feedback and observation for motor learning: Application to the roundoff movement in gymnastics

Le Naour, Thibaut ; Ré, Chiara ; Bresciani, Jean-Pierre

In: Human Movement Science, 2019, vol. 66, p. 564-577

In this paper, we assessed the efficacy of different types of visual information for improving the execution of the roundoff movement in gymnastics. Specifically, two types of 3D feedback were compared to a 3D visualization only displaying the movement of the expert (observation) as well as to a more ‘traditional’ video observation. The improvement in movement execution was measured using...
