We propose a novel conceptual design for a Head-Mounted Projection Display (HMPD) with Eye-Tracking (ET) capabilities. We present a fully integrated system that is robust, easy to calibrate, inexpensive, and lightweight. The HMD-ET integration is performed from a low-level optical configuration in order to achieve a compact, comfortable, easy-to-use system. The idea behind the full integration ...

Letter series completion problems (LSC-problems) are common tasks to measure peoples’ ability in problem solving. The process of inductive reasoning in solving such problems was investigated in an experiment by the means of eye movement analysis. We developed an eye movement model on the basis of a process model by Simon and Kotovsky (1963). Our model assigns specific eye movements to three dif...

Dry eye is one of the most commonly encountered problems in ophthalmology. Signs can include punctate epithelial erosions, hyperemia, low tear lakes, rapid tear break-up time, and meibomian gland disease. Current methods of diagnosis include a slit-lamp examination with and without different stains, including fluorescein, rose bengal, and lissamine green. Other methods are the Schirmer test, te...

OBJECTIVE To report a flash photography-induced maculopathy. METHODS A professional photographer blinded himself accidentally and he consulted 3 days after the event with a scotoma in his dominant left eye. A unilateral acute light-induced maculopathy with hemorrhage was observed. The lesion was studied with colour photography, fluorescein and indocyanin angiography, autofluorescence imaging ...

An 82-year-old female presented with sudden painless decrease in vision in the right eye after awakening. She could see the "superior half" of her vision from the right eye only. On examination, best-corrected vision was 20/300 in the right eye and 20/30 in the left eye. The fundus in the right eye revealed recent superotemporal branch retinal artery occlusion (BRAO) with calcified plaque at th...

A real-time eye diagram monitoring method for optical signals is proposed and experimentally demonstrated based on sampling. In the system, under test are directly sampled by an sampling pulse train with a narrow width high repetition frequency. The achieved in Mach-Zehnder modulator (MZM), gated on-off electrical pulse. then broadened detected photodetector (PD). low-speed analog-to-digital co...
