Amyotrophic lateral sclerosis, also known as ALS, is a progressive nervous system disorder that affects nerve cells in the brain and spinal cord, resulting loss of muscle control. For individuals with where mobility limited to movement eyes, use eye-tracking-based applications can be applied achieve some basic tasks certain digital interfaces. This paper presents review existing eye-tracking so...

In this paper we present a novel approach for automatically tracking the reading progress using a combination of eye-gaze tracking and speech recognition. The two are fused by first generating word probabilities based on eye-gaze information and then using these probabilities to augment the language model probabilities during speech recognition. Experimental results on a small dataset show that...

Video-based eye tracking typically relies on tracking the pupil and a first-surface corneal reflection (CR) of an illumination source. The positional difference between these two features is used to determine the observer’s eye-in-head orientation. With the use of head-mounted eye trackers, this positional difference is unavoidably affected by relative movements between the eye tracking camera ...

The eye is not only one of the most complex but also the most important sensory organ of the human body. Eye detection and eye tracking are basement and hot issue in image processing. A noninvasive eye location and eye tracking is promising for hands-off gaze-based human–computer interface, fatigue detection, instrument control by paraplegic patients and so on. For this purpose, an innovation w...

Analysis of eye movement data provides a valuable methodology to evaluate and inform user interface design. However, there are a number hurdles that must be overcome on the path to successfully gaining meaningful eye movement data. We describe how we used a commercially available eye tracking system to evaluate a new interface for personal desktop search called Phlat. A small eye-tracking user ...

The ISO 9241-9 standard for computer pointing devices proposes an evaluation of performance and comfort [4]. This paper is the first eye tracking evaluation conforming to ISO 9241-9. We evaluated three techniques and compared them with a standard mouse. The evaluation used throughput (in bits/s) as a measurement of user performance in a multi-directional point-select task. The "Eye Tracking Lon...

Knowing the user’s point of gaze has significant potential to enhance current humancomputer interfaces. The primary obstacle of integrating eye movements into interfaces is the availability of a reliable, low-cost open-source eye-tracking system. Towards making such a system available to interface designers, we have developed a hybrid eye-tracking algorithm that integrates feature-based and mod...

Fixational eye movements remain a major cause of artifacts in optical coherence tomography (OCT) images despite the increases in acquisition speeds. One approach to eliminate the eye motion is to stabilize the ophthalmic imaging system in real-time. This paper describes and quantifies the performance of a tracking OCT system, which combines a phase-stabilized optical frequency domain imaging (O...

Eye-tracking is the measurement of eye motions and point of gaze of a viewer. Advances in this technology have been essential to our understanding of many forms of visual learning, including the development of visual expertise. In recent years, these studies have been extended to the medical professions, where eye-tracking technology has helped us to understand acquired visual expertise, as wel...
