Analyzing Transferability of Happiness Detection via Gaze Tracking in Multimedia Applications
2020
How are strong positive affective states related to eye-tracking features and how can they be used to appropriately enhance well-being in multimedia consumption? In this paper, we propose a robust classification algorithm for predicting strong happy emotions from a large set of features acquired from wearable eye-tracking glasses. We evaluate the potential transferability across subjects and provide a model-agnostic interpretable feature importance metric. Our proposed algorithm achieves a true-positive-rate of 70% while keeping a low false-positive-rate of 10% with extracted features of the pupil diameter as most important features.
