Abstract

Sposób identyfikacji obiektu fiksacji wzroku użytkownika, według wynalazku, polegający na wyznaczeniu w zbiorze obiektów grupy obiektów do identyfikacji i mierzeniu punktów patrzenia użytkownika przez eye tracker, charakteryzuje się tym, że oblicza się w danej chwili czasu odległości każdego obiektu od punktu patrzenia użytkownika rejestrowanego przez eye tracker. Następnie wylicza się dla każdego obiektu prawdopodobieństwo spójności położenia, które stanowi średnia ważona bazująca na rozkładzie normalnym, oraz oblicza się prawdopodobieństwo spójność prędkości pomiędzy prędkością zmiany położenia punktów patrzenia i prędkością zmiany położenia danego obiektu. Oblicza się dla każdego obiektu prawdopodobieństwo fiksacji, które stanowi sumę prawdopodobieństw spójności położenia oraz spójności prędkości. Obiekt fiksacji identyfikuje się za pomocą prawdopodobieństwa fiksacji wraz z algorytmem opartym o Ukryte Modele Markowa, w którym stanami są fiksacje na obiektach wyznaczonych do identyfikacji.The method of identifying a user's eye fixation object, according to the invention, consisting in designating a group of objects in the set of objects for identification and measuring the user's view points by the eye tracker, is characterized by calculating at a given time the distance of each object from the user's point of view recorded by the eye tracker. Then, the probability of the position consistency is calculated for each object, which is a weighted average based on the normal distribution, and the likelihood of the speed consistency between the speed of changing the position of the look points and the speed of changing the position of the given object is calculated. The probability of fixation is calculated for each object, which is the sum of the probabilities of position consistency and speed consistency. The fixation object is identified by the fixation probability along with an algorithm based on Hidden Markov Models, in which the states are fixations on the objects designated for identification.
