2. 1. Off-line Foveated Compression and Scene Perception: An Eye-Tracking Approach

   Author : Marcus Nyström; Humanistlaboratoriet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gaze prediction; off-line foveation; scene perception; eye-tracking; compression;

   Abstract : With the continued growth of digital services offering storage and communication of pictorial information, the need to efficiently represent this information has become increasingly important, both from an information theoretic and a perceptual point of view. There has been a recent interest to design systems for efficient representation and compression of image and video data that take the features of the human visual system into account. READ MORE

4. 2. Datadriven Human Intention Analysis : Supported by Virtual Reality and Eye Tracking

   Author : Julius Pettersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; eye tracking; Virtual reality VR ; deep machine learning; time series analysis; psychological testing.; collaborative robots; human intention prediction; uncertainty estimation;

   Abstract : The ability to determine an upcoming action or what decision a human is about to take, can be useful in multiple areas, for example in manufacturing where humans working with collaborative robots, where knowing the intent of the operator could provide the robot with important information to help it navigate more safely. Another field that could benefit from a system that provides information regarding human intentions is the field of psychological testing where such a system could be used as a platform for new research or be one way to provide information in the diagnostic process.

5. 3. Calibration in deep-learning eye tracking

   Author : Erik Lindén; Alexandre Proutiere; Thomas Schön; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Personal variations severely limit the performance of appearance-based gaze tracking. Adapting to these variations using standard neural network model adaptation methods is difficult. The problems range from overfitting, due to small amounts of training data, to underfitting, due to restrictive model architectures. READ MORE

6. 4. One of a kind. The processing of indefinite one-anaphora in spoken Danish

   Author : Philip Diderichsen; Kognitionsvetenskap; []
   Keywords : HUMANIORA; HUMANITIES; Accessibility; Referring expressions; Eye-tracking; Givenness; Spoken Danish; Visual World paradigm; Definiteness; Spoken language processing;

   Abstract : It is a hallmark of natural language use that the way we talk about something reflects how it is represented in the mind of our conversation partner. This thesis studies the use and cognitive processing of referring expressions like one in comparison with other expression types in spoken Danish. READ MORE

7. 5. Volterra Modeling and Estimation of the Human Smooth Pursuit

   Author : Viktor Bro; Alexander Medvedev; Geoff Chase; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volterra models; Volterra-Laguerre models; Nonlinear modeling; Smooth pursuit; Eye tracking; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Abstract : This thesis treats the mathematical modeling of the human smooth pursuit system using Volterra-Laguerre models. The smooth pursuit system allows for tracking of moving objects. Since it is a complex system including the muscles of the eye, nerves and certain parts of the brain, the system may be impaired if some part is compromised. READ MORE
