A small-scale hyperacute compound eye featuring active eye tremor: application to visual stabilization, target tracking, and short-range odometry

Dario Floreano

In this study, a miniature artificial compound eye (15 mm in diameter) called the curved artificial compound eye (CurvACE) was endowed for the first time with hyperacuity, using similar micro-movements to those occurring in the fly's compound eye. A period ...

3D Tangibles Facilitate Joint Visual Attention in Dyads

Pierre Dillenbourg, Kshitij Sharma, Guillaume Zufferey, Sébastien Cuendet, Bertrand Roland Schneider

We report results from a dual eye-tracking study around a Tangible User Interface (TUI). Participants (N=54) worked in groups of two and solved optimization problems on the TinkerTable, a TUI designed for students in logistics. The TinkerTable features tan ...

Screen or Tabletop: An Eye-Tracking Study of the Effect of Representation Location in a Tangible User Interface System

Pierre Dillenbourg, Beat Adrian Schwendimann, Sébastien Cuendet, Mina Shirvani Boroujeni, Lorenzo Lucignano

This article presents a comparison of the effects of input-output location (co-located versus discrete) on user performance in a tangible user interface (TUI) system. We conducted a mobile eye-tracking study with two different versions of a TUI system and, ...

Are All Pixels Equally Important? Towards Multi-Level Salient Object Detection

Gökhan Yildirim

When we look at our environment, we primarily pay attention to visually distinctive objects. We refer to these objects as visually important or salient. Our visual system dedicates most of its processing resources to analyzing these salient objects. An ana ...

Visual-induced expectations modulate auditory cortical responses

Lukasz Grzeczkowski

Active sensing has important consequences on multisensory processing (Schroeder et al.,2010). Here, we asked whether in the absence of saccades, the position of the eyes and the timing of transient color changes of visual stimuli could selectively affect t ...

Molecular Analysis of NOTCH2 in Patients with Primary Open-Angle Glaucoma

Background and Purpose: Transgenic mice over-expressing Notch2 in the uvea exhibit a hyperplastic ciliary body leading to increased IOP and glaucoma. The aim of this study was to investigate the possible presence of NOTCH2 variants in patients with primary ...

Studying teacher orchestration load in technology-enhanced classrooms: A mixed-method approach and case study

Pierre Dillenbourg, Kshitij Sharma

Teacher orchestration of technology-enhanced learning (TEL) processes plays a major role in students' outcomes, especially in face-to-face classrooms. However, few studies look into the fine-grained details of how such orchestration unfolds, the challenges ...

Camera-based estimation of student's attention in class

Mirko Raca

Two essential elements of classroom lecturing are the teacher and the students. This human core can easily be lost in the overwhelming list of technological supplements aimed at improving the teaching/learning experience. We start from the question of whet ...

The Dynamics of Shadow: Architecture of Natural Light in Extreme Latitudes

Marilyne Andersen, Mandana Sarey Khanie, María Lovísa Ámundadóttir, Siobhan Francois Rockcastle

While architecture is composed of static structural elements, daylit space is perceived as a dynamic play of light and shadow – ephemeral qualities that add depth, texture, and movement to spatial composition. Our perception of architecture is greatly impa ...
