Abstract

Visual Search target inference subsumes methods for predicting the target object through eye tracking. A person intents to find an object in a visual scene which we predict based on the fixation behavior. Knowing about the search target can improve intelligent user interaction. In this work, we implement a new feature encoding, the Bag of Deep Visual Words, for search target inference using a pre-trained convolutional neural network (CNN). Our work is based on a recent approach from the literature that uses Bag of Visual Words, common in computer vision applications. We evaluate our method using a gold standard dataset.
