Algorithms that alter the image on a screen, depending on the user's eyewear recipe, are at the heart of technology developed by researchers at the University of California, Berkeley, in collaboration with MIT scientists and Microsoft.
According to an MIT publication Technology Review, the algorithm changes the light from each individual pixel through a light filter in front of the screen so that the light rays reach the retina in a way that results in a clear image. The central idea, according to the researchers, is to predict how an eye (for example, with nearsightedness) will distort the image (something that glasses correct) and proactively change it so that the viewer can see it clearly.
Κατά τον Μπράιαν Μπάρσκι, καθηγητή επιστήμης υπολογιστών και έναν από τους συντελεστές του σχετικού paper, στην ουσία είναι σαν να αλλάζει αυτό που πρόκειται να κάνει η οπτική του ματιού. Η συγκεκριμένη τεχνική, πέρα από το να βοηθά ανθρώπους με απλά/ συνηθισμένα προβλήματα όρασης να χρησιμοποιούν οθόνες χωρίς γυαλιά, ενδεχομένως να φανεί χρήσιμη και σε άτομα με πιο σημαντικά προβλήματα, τα οποία δεν διορθώνονται με φακούς επαφής ή γυαλιά. Αν και παρόμοιες μέθοδοι έχουν δοκιμαστεί και στο παρελθόν, η νέα αυτή προσέγγιση έχει αποτέλεσμα καθαρότερη εικόνα με υψηλό contrast.
The paper is to be presented at the annual International Conference and Exhibition on Computer Graphics and Interactive Techniques στο Βανκούβερ. Για τους σκοπούς της researchs 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 eye of the beholder. The images were then projected onto the screen of an iPod Touch, where a special filter had been applied.
According to Gordon Waughstein, MIT Media Lab researcher who participated in the research, the next step will be to create screens that can be used by the general public - something that is expected to happen in a few years, as there are still challenges ahead of the specific an issue such as the fact that the technique currently requires the user to keep his eyes immobile and that he can not currently work for more than one person who is looking at the screen at the same time.
