“…The eye-tracker was designed to: a) be invisible to the viewer so that interaction could be, at least initially, implicit; b) not require calibration; c) be reliable and able to run long periods of time; d) be inexpensive, so that the piece could be left unattended in public spaces. Each of the two eye-trackers consisted of a hot mirror (a mirror that only reflects infrared light), a low-resolution Logitech webcam, modified with a filter to be sensitive only to infra-red light (with its internal infrared-blocking filter removed), two sources of infrared light (LEDs) to generate corneal reflections, and a customized version of the ITU Gaze Tracker software [23] to perform the analysis, which was fed to the CAS software described below and run in the same machine (a Windows PC). The hot mirror, located at 45º from the line of sight, allowed us to place the camera and infrared light sources very close and perpendicular to the eye and therefore obtain a very large image of the pupil without making any of the machinery visible.…”

We present A Delicate Agreement, an interactive art installation designed to intrigue viewers by offering them an unfolding story that is endlessly fascinating. To achieve this, we set our story in the liminal space of an elevator, and populated this elevator with a set of unique characters. Viewers watch the story unfold through peepholes in the elevator's doors, where in turn their gaze can trigger changes in the storyline. This storyline's interactive response was created via a complex adaptive system using simple rules based on Goffman's performance theory.

Abstract. A virtual avatar or autonomous agent is a digital representation of a human being that can be controlled by either a human or an artificially intelligent computer system. Increasingly avatars are becoming realistic virtual human characters that exhibit human behavioral traits, body language and eye and head movements. As the interpretation of eye and head movements represents an important part of nonverbal human communication it is extremely important to accurately reproduce these movements in virtual avatars to avoid falling into the well-known "uncanny valley". In this paper we present a cheap hybrid real-time head and eye tracking system based on existing open source software and commonly available hardware. Our evaluation indicates that the system of head and eye tracking is stable and accurate and can allow a human user to robustly puppet a virtual avatar, potentially allowing us to train an A.I. system to learn realistic human head and eye movements.

Abstract-This paper describes the current state of the work aimed towards an affective application of BCI to the task of complex data visual exploration. The developed technological approach exploits the idea of supporting tacit and complex domain-specific knowledge acquisition during the examination of visual images built using large input data sets. The presented experimental research on the complex network data exploration process shows the capabilities of the presented approach through the analysis of a user's affective state estimation.
