Pupil detection methods for eye tracking

Journal of Applied Computer Science

Vol. 26, nr 2

201--211

The theory that pupillary changes can reflect human psychophysical character was confirmed in several conducted studies. Authors of those studies have used devices called eye trackers in order to measure pupillary changes, blinking rate, eye movement patterns or even a gaze position. The main goal of those apparatuses is to locate the pupil on a given image using implemented pupil detection algorithms. In this paper the main focus will be set on several states of art pupil detection methods. All represent different approaches to performing the same tasks in diffcult situations for ex.: low/high condition, low image resolutions or low contrast.

Affective pathfinding in video games

Daszuta M., Wróbel F., Rynkiewicz F., Szajerman D., Napieralski P.

Vol. 26, nr 2

23--29

To allow player submerge in created environment of a video game, agents called Non-Player Characters (NPCs) should act believably. One of the most vital aspect, in case of NPCs is pathfinding. There are a few methods that allow change path finding algorithms to become more human-like. Yet, those are not considering many vital aspects of human decisions regarding path choosing. The main purpose of this paper is to present known approaches and show example of a new approach that wider considers psychological aspects of decision making in case of choosing a path.
