Algorithms that change the picture on a screen, depending on the user's glasses prescription, is at the "heart" of the technology being developed by researchers at the University of California, Berkeley, in collaboration with scientists from MIT and Microsoft.
According to a publication by MIT Technology Review, ο αλγόριθμος αλλάζει το φως από το κάθε μεμονωμένο πίξελ μέσω ενός φίλτρου φωτός μπροστά στην οθόνη, έτσι ώστε οι ακτίνες φωτός να φτάνουν στον αμφιβληστροειδή χιτώνα με τρόπο που έχει ως αποτέλεσμα καθαρή εικόνα. Η κεντρική ιδέα, σύμφωνα με τους ερευνητές, είναι να προβλέπεται πώς ένα μάτι (για παράδειγμα, με μυωπία) θα παραμορφώνει την εικόνα (κάτι που διορθώνουν τα γυαλιά) και να την αλλάζει προληπτικά, έτσι ώστε ο θεατής να την βλέπει καθαρά.
According to Bryan Barsky, a computer science professor and one of the contributors of the paper, it is basically like changing what the eye's eye is about to do. This technique, in addition to helping people with simple / common sight problems to use glasses-free screens, may also be useful for people with more serious problems that are not corrected by contact lenses or glasses. Although similar methods have been tried out in the past, this new approach results in a cleaner image with high contrast.
The paper is to be presented at the annual International Conference and Exhibition on Computer Graphics and interactive Techniques in Vancouver. For the purposes of the research, images of objects such as a colorful balloon or a portrait of Vincent Van Gogh were taken and algorithms were used that distorted the image taking into account the data of the viewer's eye. The images were then projected onto the screen of an iPod Touch, where a special filter had been applied.
According to Gordon Wedgestein, a researcher at the MIT Media Lab who participated in the research, the next step will be to creation screens that can be used by the general public - something that is expected to happen within a few years, as there are still challenges in this matter, such as that the technique currently requires the user to keep their eyes still and that cannot currently work for more than one person looking at the screen at the same time.
