Received (received date) Revised (revised date) An approach to distance sensor data integration that obtains a robust interpretation of the robot environment is presented in this paper. This approach consists in obtaining patterns of fuzzy distance zones from sensor readings; comparing these patterns in order to detect non-working sensors; and integrating(More)
Reaching a target object requires accurate estimation of the object spatial position and its further transformation into a suitable arm-motor command. In this paper, we propose a framework that provides a robot with a capacity to represent its reachable space in a more adaptive way. The location of the target is represented implicitly by both the gaze(More)
One problem web users often face is that of remembering which previously visited page is likely to contain some particular piece of information they are now interested in. To ease this revisitation task, we propose a novel approach: using "live" thumbnails, or small video-like animations of a web page. Our approach is grounded on a two-fold notion: (1) live(More)
Behavioural Avoidance Tests (BATs) are commonly used for assessing phobias. While easy to deploy, these tests have some practical difficulties. For instance, therapists have to make distance estimations that are hard to do with accuracy and objectivity; or information regarding the performance of the patients (e.g. their walking pattern) is lost.
