Modeling visual sampling on in-car displays: The challenge of predicting safety-critical lapses of control
2015
In this article, we study how drivers interact with in-car interfaces, particularly by focusing on understanding driver in-car glance behavior when multitasking while driving. The work focuses on using an in-car touch screen to find a target item from a large number of unordered visual items spread across multiple screens. We first describe a cognitive model that aims to represent a driver?s visual sampling strategy when interacting with an in-car display. The proposed strategy assumes that drivers are aware of the passage of time during the search task; they try to adjust their glances at the display to a time limit, after which they switch back to the driving task; and they adjust their t…

The Mona Lisa effect: Testing the limits of perceptual robustness vis-à-vis slanted images
2014
We report three experiments that test the limits of the Mona Lisa effect. The gaze of a portrait that is looking at us appears to follow us around as we move with respect to the picture. Even if our position is shifted considerably to the side, or if the picture is severely slanted, do we feel the gaze to be directed at us? We determined the threshold where this effect breaks down to be maximally 70? of picture slant relative to the observer. Different factors modulate this remarkable robustness, among them being the display medium and the nature of the picture. The threshold was considerably lower when the picture was mounted on a physical surface as opposed to a computer simulation of sla…
The Mona Lisa effect: Neural correlates of centered and off-centered gaze
2014
The Mona Lisa effect describes the phenomenon when the eyes of a portrait appear to look at the observer regardless of the observer's position. Recently, the metaphor of a cone of gaze has been proposed to describe the range of gaze directions within which a person feels looked at. The width of the gaze cone is about five degrees of visual angle to either side of a given gaze direction. We used functional magnetic resonance imaging to investigate how the brain regions involved in gaze direction discrimination would differ between centered and decentered presentation positions of a portrait exhibiting eye contact. Subjects observed a given portrait's eyes. By presenting portraits with varyin…
Strategies of Eliciting Young People’s Affective and Quick Participation in a Youth Magazine’s Instagram Community
2022
Traditional media have merged with social media and pursue to produce engaging content and form relationships with online audiences. At the same time, social media has allowed young people a venue to practice their basic needs of interaction, identity, and self-expression, and provides communities of shared issues and social/political aspirations. By analysing the Instagram post caption data of the largest Finnish (girls’) youth magazine, this case study investigated what posting strategies used by the magazine elicited youth participation, and how do the strategies and participation align with young people’s media and online communication preferences. The study found the magazine to use va…
Refracting the Analytical Gaze: Studying Media Representations of Migrant Death at the Border

L'attaccamento ai luoghi come modello interpretativo delle relazioni dell'uomo con la cultura. Una ricerca su un campione di ragazzi tunisini della c…
2014
L'attaccamento al luogo è un essenziale bisogno umano in grado di nutrire il senso dell'identità di individui e collettività, a prescindere dai cambiamenti della società. Intento principale in questo lavoro di tesi è quello dell'integrazione, legato al fenomeno dell' intercultura. Il lavoro di tesi è riferito nello specifico nella città di Mazara del Vallo, centro nevralgico di incontro di culture. Ho scelto di indagare la percezione del luogo da parte della popolazione immigrata, coinvolgendo in particolare gli adolescenti che costituiscono la cosiddetta "seconda generazione", e confrontandone le opinioni con quelle espresse dai coetanei autoctoni. L'aspetto più propriamente statistico rig…
L’interdipendenza delle obbligazioni nella compravendita conclusa tramite intermediario libero (‘institor’ o ‘procurator’)
2007
Il lavoro si occupa dell'interdipendenza delle prestazioni nell'ambito del negozio di compravendita nelle fonti del diritto romano.In particolare, il problema viene studiato in relazzione alle compravendite concluse da un intermediario, institor o procurator.
Hidden Pursuits: Evaluating Gaze-selection via Pursuits when the Stimuli's Trajectory is Partially Hidden
2018
The idea behind gaze interaction using Pursuits is to leverage the human's smooth pursuit eye movements performed when following moving targets. However, humans can also anticipate where a moving target would reappear if it temporarily hides from their view. In this work, we investigate how well users can select targets using Pursuits in cases where the target's trajectory is partially invisible (HiddenPursuits): e.g., can users select a moving target that temporarily hides behind another object? Although HiddenPursuits was not studied in the context of interaction before, understanding how well users can perform HiddenPursuits presents numerous opportunities, particularly for small interfa…
The cone of gaze
2011
Gaze direction is an important cue that regulates social interactions. Although humans are very accurate in determining gaze directions in general, they have a surprisingly liberal criterion for the presence of mutual gaze. We first established a psychophysical task to measure the cone of gaze, which required observers to adjust the eyes of a virtual head to the margins of the area of mutual gaze. Then we examined differences between 2D, 3D, and genuine real life gaze. Finally, the tolerance for image distortions when the virtual head is not viewed from the proper vantage point was investigated. Gaze direction was remarkably robust toward loss in detail and distortion. Important lessons for…
