  • Patent number: 11941172
    Abstract: A method for training an eye tracking model is disclosed, as well as a corresponding system and storage medium. The eye tracking model is adapted to predict eye tracking data based on sensor data from a first eye tracking sensor. The method comprises receiving sensor data obtained by the first eye tracking sensor at a time instance and receiving reference eye tracking data for the time instance generated by an eye tracking system comprising a second eye tracking sensor. The reference eye tracking data is generated by the eye tracking system based on sensor data obtained by the second eye tracking sensor at the time instance. The method comprises training the eye tracking model based on the sensor data obtained by the first eye tracking sensor at the time instance and the generated reference eye tracking data.

  • Publication number: 20220043509
    Abstract: A system configured to enable operation of an apparatus based on the gaze of a user, the system comprising a processor, and a memory comprising instructions executable by the processor, wherein the system is configured to determine a gaze region of a user among a plurality of regions associated with the apparatus, wherein the plurality of regions comprises at least one primary gaze region and at least one secondary gaze region and perform at least one action based on the determination of the gaze region, wherein the system is configured to determine the gaze region using a first gaze estimation algorithm and/or a second gaze estimation algorithm.

  • Publication number: 20210256353
    Abstract: Techniques for using a deep generative model to generate synthetic data sets that can be used to boost the performance of a discriminative model are described. In an example, an autoencoding generative adversarial network (AEGAN) is trained to generate the synthetic data sets. The AEGAN includes an autoencoding network and a generative adversarial network (GAN) that share a generator. The generator learns how to the generate synthetic data sets based on a data distribution from a latent space. Upon training the AEGAN, the generator generates the synthetic data sets. In turn, the synthetic data sets arc used to train a predictive model, such as a convolutional neural network for gaze prediction.
