Abstract
Images are one of the key elements of the content of the World Wide
Web. One group of web images are also photos of people. When various
institutions (universities, research organizations, companies, associations,
etc.) present their staff, they should include photos of people for
the purpose of more informative presentation. The fact is, that there are
many specifies how people see face images and how do they remember
them. Several methods to investigate person’s behavior during use
of web content can be performed and one of the most reliable method
among them is eye tracking. It is very common technique, particularly
when it comes to observing web images. Our research focused on
behavior of observing face images in process of memorizing them.
Test participants were presented with face images shown at different
time scale. We focused on three main face elements: eyes, mouth and
nose. The results of our analysis can help not only in web presentation,
which are, in principle, not limited by time observation, but especially
in public presentations (conferences, symposia, and meetings).

Abstract
Utilization of eco-font for office printing is one of sustainable, “green”
printing concepts, which besides obvious economic benefits, as a result has
a certain effect on environmental sustainability as well. The fundamental
problem that this practice faces is decreased quality of text printed using
eco-fonts comparing to those printed with regular fonts. The aim of this
research is eco-font efficiency estimation, i.e. determination of toner usage
reduction level of ink jet printed documents typed with this font type, as well
as estimation of the extent humans perceive differences between text printed
with eco-font and the one printed by its „non-eco“ equivalent. Combining
instrumental measuring method and digital image analysis, it was found that
this simple principle (eco-font utilization) enables substantial toner usage
reduction for an ink jet printing system, while visual test showed that visual
experience of text printed using eco-font is sufficient. In addition, awareness
of benefits that eco-font utilization brings, change users’ attitude towards
eco-font quality.

Abstract
The aim of the research was to produce tactile floor plans for blind and
visually impaired people for the use in the museum. For the production
of tactile floor plans 3D printing technique was selected among three
different techniques. 3D prints were made of white and colored ABS polymer
materials. Development of different elements of tactile floor plans, as well as
the problems and the solutions during 3D printing, are described in the paper.

Abstract
The paper presents a model of factors that influence on the quality of
relief-dot Braille inscriptions in their intensive use by blind people. It was
constructed matrix of depending and distancing by using a directed graph.
It allowed establish a hierarchy between studied criteria’s of impact the
on durability of relief prints. It was developed a basic structure of digital
system of assessment the conformity of Braille symbols to applicable
international standards and definition of operational stability.
