Eye-tracking technology and gaze-contingent control in human-computer interaction have become an objective reality. This article reports on a series of eye-tracking experiments, in which we concentrated on one aspect of gaze-contingent interaction: Its effectiveness compared with mouse-based control in a computer strategy game. We propose a measure for… (More)
Digoxin pharmacokinetics was studied in 40 virtually healthy subjects aged 60-89 years and 10 subjects aged 20-29 years injected with a single dose (0.5 mg) of digoxin. The pharmacokinetic data were interpreted in terms of a two-compartmental model. The constant of digoxin transfer rate from the peripheral compartment to the central one appreciably… (More)
Forty patients of elderly and senile ages with chronic obstructive bronchitis, complicated with degrees II-III respiratory insufficiency, and chronic cor pulmonale with stage IIA circulatory failure have been examined. The examination revealed impairment of the external respiration and tissue oxygen exchange, changes in the cardio- and hemodynamics the most… (More)
Understanding software engineers' behaviour plays a vital role in the software development industry. It also provides helpful guidelines for teaching and learning. In this article, we conduct a study of the extrafoveal vision and its role in information processing. This is a new perspective on source code comprehension. Despite its major importance, the… (More)
Demos at UBICOMP 2015 provided researchers with an opportunity to present their latest cutting-edge research, but also early implementations, prototypes, work-in-progress systems, and commercial products. At UBICOMP, demos offer a chance for authors to engage the attendees and media representatives at a personal level and let them see, touch, and experience… (More)
The authors determined the levels of oral glucose tolerance, of serum insulin and of the serum lipids in 143 patients of advanced age suffering from ischaemic heart disease. They point out the importance of the relationship between disturbed lipid and carbohydrate metabolisms which cause coronary arteriosclerosis via hyperinsulinism.
