We show that a simple low-dimensional representation of movie patches, namely local spectral energy, can be used to predict where people will look in dynamic natural scenes. We then present a gaze-contingent display that modifies local spectral energy in real time. This modification of the saliency distribution of the scene leads to a change in eye movement statistics. Our research aims at the ...

We present experimental evidence from a study in which we monitor eye movements as people respond to pre-recorded instructions generated by a human speaker and by two text-tospeech synthesizers. We replicate findings demonstrating that people process human speech incrementally, making partial commitments as a word unfolds. Specifically, they entertain multiple lexical candidates on the fly depe...

We propose an integrated model of the saccadic circuitry involved in target selection and motor command. It includes the Superior Colliculus and the Basal Ganglia in both cortical and subcortical loops. This model has spatial and feature-based learning capabilities which are demonstrated on various saccade tasks on a robotic platform. Results show that it is possible to learn to select saccades...

This paper presents systems which enable eye contact in leisure video conferencing. The proposed solutions include a software based and a hardware based approach. Two experiments were conducted to test the performance of the systems by measuring the users’ sense of presence. The results showed that both solutions succeeded in establishing eye contact but there was no direct indication of an inc...

The core objective of this study is to understand individuals IS usage by going beyond the traditional subjective self-reported and objective system-log measures to unveil the delicate process through which users interact with IS. In this study, we conducted a laboratory experiment to capture users’ eye movement and, more importantly, applied a novel methodology that uses the Gaussian mixture m...

We present static and dynamic techniques to visualize perfusion data and to relate perfusion data to morphologic image data. In particular, we describe the integrated analysis of MRI myocardial perfusion data with CT coronary angiographies depicting the morphology. We refined the Bull’s-Eye Plot, a wide-spread and accepted analysis tool in cardiac diagnosis, to show aggregated information of pe...

PURPOSE To compare methods of calculating intraocular lens (IOL) power for cataract surgery in eyes that have undergone myopic laser-assisted in-situ keratomileusis (LASIK). METHODS Eleven eyes of eight patients who had previously undergone myopic LASIK (amount of LASIK correction, -5.50 +/- 2.61 D (SD); range, -8.78 to -2.38 D) and subsequently phacoemulsification with implantation of the SA...

This opening chapter begins with an overview of the issues and questions addressed in the remainder of this volume, the contents of which reflect the wide diversity of eye movement research. We then provide the reader with an up to date impression of the most significant developments in the area, based on findings from a survey of eye-movement researchers and database searches. We find that the...
