Abstract: A mapping method is disclosed that includes (i) memorizing at least one reference image of an environment to be mapped containing a specific arrangement of a plurality of markers organized in cells; wherein each cell is identified by a marker or by a combination of markers; the plurality of markers comprising at least a number of different types of markers equal to a type-number; (ii) detecting, by a moving video camera, a video sequence wherein the environment to be mapped is, at least in part, framed; (iii) identifying in at least one frame of the video sequence one or more cells being part of the specific arrangement of markers of the reference image; and (iv) calculating, on the basis of the data regarding the identified cells, at least one homography for the perspective transformation of the coordinates acquired in the video sequence into coordinates in the reference image and vice versa.

Abstract: Object of the present invention are a method and a system for monitoring a user's attention distribution in the course of a digital image exploration, adapted to produce feedback that give the user himself an indication of the efficacy of the exploration performed, even on the basis of the relevance that the various zones of the image have in relation to a certain goal, relevance that can possibly be determined by an expert system responsible for examining the image as a function of the above-mentioned objective.

Abstract: A calibration method for an eye tracker provides for the defining of at least one first region of attraction of a first image to be displayed to a user; acquiring a first sequence of data relative to the eye movement of a user who is looking at the first image by means of an eye tracker; calculating at least a plurality of first calibration positions by means of respective calibration functions on the basis of a first gaze determined from the first sequence of data relative to eye movement; assigning a first score to each calibration function on the basis of the respective first calibration position and the first region of attraction; and selecting one of the calibration functions on the basis of the score.

Abstract: The method and apparatus object of this invention refer to a system for using generic software applications by means of ocular control characterized by simple interaction techniques which minimize the cognitive effort of the user required to manipulate the software and which permit to overcome the problems resulting from the intrinsic problem of accuracy of eye-tracking systems. Indeed, such technique does not provide using the pointer of the mouse moved by means of the gaze to control the various software applications but to use a separate application which through the use of suitable interaction techniques is comfortable and does not involve an increased effort of concentration by the user. An attempt has indeed been made to simplify the process of interaction between the user and machine also by means of the use of visual feedback which allows the same operations of the mouse to be performed by the user without the typical user frustration due to the problems of accuracy of the eye-tracking device.

Abstract: The method and the apparatus object of present invention refers to a system and A method that create, save and format text documents using a device with gaze control and a system of quick positioning of the cursor. The present invention provides a faster interaction and requires a minimum effort with respect to the state of the art interfaces.

Abstract: The present invention concerns a method and a system for the management of a station of visualisation, processing and analysis of images based on not manuals commands, particularly optical and vocal, and able to provide a feedback to the user to direct the further exploration of the medical images.
