Pixel art is a kind of digital art that through per-pixel manipulation enables production of a diverse array of artistic images. In this paper, we present a new way for people to experience and express pixel art. Our digital art consists of a set of sticks made of acrylate resin, each of which refracts light from a parallel light source, in certain directions. Artistic users are able to easily ...

This experiment assessed the effect of the amount of physical detail in pictures on picture recognition memory for 7-year-olds, 9-year-olds, young adults, and older adults over 68. Subjects were presented simple and complex line drawings, factorially combined in a "same-different" recognition test with simple or complex forms of each. For each age group, recognition accuracy was significantly h...

If dyslexic individuals have the ability to express themselves in different ways, particularly in the field of modern graphic design, would they be a favoured group in creating the extraordinary and outstanding ideas that are required in communication design? The study group consisted of 20 primary school dyslexics between ages of 7-12 and 20 non-dyslexics serving as a control group. A jury wit...

Male and female specimens of six new spider species of the family Phrurolithidae were collected from the Fanjing Mountain Nature Reserve: Otacilia microstoma sp. nov., O. songi sp. nov., O. subliupan sp. nov., Phrurolithus anticus sp. nov., P. fanjingshan sp. nov. and P. zhouyun sp. nov.. Photographs, line drawings and descriptions of all species are provided in the current study. Additionally,...

In this work we present novel axes-based visualizations that can be used to explore and analyze multivariate time series data. We propose different types of interactive axes, which in turn can be used to compile novel 3D axes arrangements. The proposed axesbased visualizations utilize an exposed central time axis around which axes representing time-dependent attributes are arranged. Each depend...

Research on animals, infants, children, and adults provides evidence that distinct cognitive systems underlie navigation and object recognition. Here we examine whether and how these systems interact when children interpret 2D edge-based perspectival line drawings of scenes and objects. Such drawings serve as symbols early in development, and they preserve scene and object geometry from canonic...

Here we present three interactive artworks that showcase the abilities of active textured surfaces to enable new qualities of surface interactions. Giving the surfaces different sensing abilities, ways to act and behaviors, then allows us to explore emotional attributes and character perceived by an observer. The three designs reflect artworks emotional perception of the observer and the result...

The current study analyzed figure size modification in different types of spatial context (C. Lange-Küttner, 1997, Lange-Küttner, 2004) for sequence and practice effects. Children of 7, 9, and 11 years of age, as well as 17-year-olds, drew figures in a series of ready-made spatial axes systems, which (a) logically increased in dimensional complexity as in child development, (b) were randomized ...

We consider guarding a city of k vertical buildings, each having a rectangular base, by placing guards only at vertices. The aim is to use the smallest number of guards. The problem is a 2.5D variant of the traditional art gallery problem, and finds applications in urban security. We give upper and lower bounds on the number of guards needed for a few versions of the problem. Specifically, we p...
