The physical appearance and behavior of a robot is an important asset in terms of Human-Computer Interaction. Multimodality is also fundamental, as we humans usually expect to interact in a natural way with voice, gestures, etc. People approach complex interaction devices with stances similar to those used in their interaction with other people. In this(More)
—Extracting eye movement events from raw data has become important upon the introduction of affordable eye trackers. The common approach in current algorithms is that they take into account velocity and position information separately. In this paper, we analyze the pros and cons of the current algorithms and introduce a novel algorithm based on the(More)
Complex human-computer interfaces are more and more making use of high-level concepts extracted from sensory data for detecting aspects related to emotional states like fatigue, surprise, boredom, etc. Repetitive sensory patterns, for example, almost always will mean that the robot or agent will switch to a " bored " state, or that it will turn its(More)
The widespread availability of portable computing power and inexpensive digital cameras is opening up new possibilities for retailers. One example is in optical shops, where a number of systems exist that facilitate eyeglasses selection. These systems are now more necessary as the market is saturated with an increasingly complex array of lenses, frames,(More)
In this paper, the introduction of a homeostatic regulation mechanism in a vision system is proposed. This homeostatic mechanism takes charge of controlling the luminance, white balance, contrast and size of the object of interest in the image, using naive methods except for the contrast, for which we have implemented a method that avoids the hill climbing(More)
