Gaze Tracking System for User Wearing Glasses
Conventional gaze tracking systems are limited in cases where the user is wearing glasses because the glasses usually produce noise due to reflections caused by the gaze tracker's lights. This makes it difficult to locate the pupil and the specular reflections (SRs) from the cornea of the user's eye. These difficulties increase the likelihood of gaze detection errors because the gaze position i...
متن کاملA Robust Gaze Tracking Method for Users Wearing Glasses
Vision-based gaze trackers that utilize corneal reflections of IR lights are vulnerable to users wearing glasses. IR reflection on eye glasses overlap with pupil region to interfere gaze estimation. This overlap problem should be resolved properly when the moving region of user is relatively large. In this paper, we propose a solution to handle the overlapping problem in gaze tracking for users...

" Tissues derived from iPSC may share with ES cells the potential to display immune privilege which may provide a 'safe haven' in which rare transformed cells may develop into tumours or viral pathogens may flourish under the radar of t...

But the giant weta from New Zealand holds the record as the heaviest insect. As a flightless insect, it has put on the bulk. A female measuring just 80 mm long has been recorded at 71 grammes. In perspective, most beetles at this length probably weigh 5 grammes and birds of this size would probably weigh 12 grammes. And, of course, the colonial insects break records. Jones notes that leafcutter...

spend the next nine months without making landfall. And it is becoming increasingly clear that very little is known about the birds during this time. As they breed only above 50 degrees latitude, they are considered cold-water birds, but researchers working with puffins breeding at England's largest colony on the Farne Islands are concerned about their winter environment as there has recently b...
