With the rapid evolution and growing complexity of infocommunication devices it is important to discuss gamification, which is exponentially used in several types of infocommunication devices. The paper is about gamification, that recently became a new phenomenon to motivate and alter favorably the behavior of the users. Gamification is a new tool for boosting user engagement in various fields. First the definition, then the elements, later a descriptive gamification model is going to be introduced. Furthermore, information about the connection between motivation and gamification can be understood. In the second part of the article examples of applied gamification in the focus of smartphone applications are going to be given.

Presented model expands the bi-directional interface for human-computer interaction. It broadens the communication channel from a man towards a computer. This is achieved by using a digital camera devices in the HCI interface and the use of novel (taken from the literature) image analysis. Proposed interface use the full bandwidth video channel, thereby increasing the interface adaptability skills. Such solution allows to expand HCI to other modalities (eg. sound). Developed mechanism of three-level adaptation allows to create an interface tailored to the expectations of the individual user. This is particularly important in the case of therapeutic treatments and persons with disabilities.

Being a new player in a multiplayer game is not an easy experience. If the game requires coordinated team play for success, an inexperienced player can receive a high amount of abuse because of what others view as bad plays. While the companies try to alleviate this problem by focusing on the offenders, we present another approach that can also help in decreasing toxic behavior. In our paper we introduce the first steps at researching what it requires to perform well in any given role in a popular multi player game, League of Legends. Using focus groups and online questionnaires we narrow down the list of abilities to 6, in which different profiles would predict different most successful playstyles. Based on these ability profiles the game itself should give more customized tutorial sessions and recommendations to new players who in turn will have an overall improved first impression. Through having better performance, we believe, that some of the toxic behavior experienced by new players can be extinguished.

In our paper we would like to introduce the organizational principles and main representation features of a knowledge base of ancient literary texts based on a three-dimensional virtual library model adopting the structure of the classification system of the ancient Library of Alexandria. Currently we are using the English translations of the selected ancient Greek texts as starting points to the knowledge base, but we intend to complete the provided content with other texts and multimedia materials. In our paper we focus on the content management and organization issues of the knowledge base. With respect to them it is crucially important to formulate our primary goals or mission, that is, why we think our collection of ancient materials could be especially useful and unique for its users. Because the average user needs a considerable amount of dictionaries and background knowledge to fully understand and interpret the ancient literary texts, the selected material should be carefully preprocessed and well organized. Our aim is to provide the necessary knowledge for each text available in the knowledge base in order that the texts could be `read at once' and without (much) effort. Therefore we introduce the cognitive framework that the preprocessing of literary texts and the representation features of our virtual library model are based on. Finally, we demonstrate our ideas by a carefully chosen example which illustrates the possible representations of two parallel translations of an ancient poem by Sappho.

The present study aims at deepening the role played by potential voters' political orientation in the effects of parodies. As previously shown for the role of in-group affect in the positive evaluation of one's own politician, the work points out how leftist voters are more negatively influenced by the critical side of a parody than rightist ones.

Adapting an automation system to the workload level of a human operator can be beneficial in many situations, e.g. at industrial workplaces or in safety-critical situations like driving and flying an aircraft. However, this requires real-time assessment of workload. We present a model-based approach for online simulation and assessment of cognitive workload, based on analysing the activities of a cognitive architecture during simulation. A driving simulator experiment was used to evaluate the approach. The cognitive workload of participants was manipulated with a variant of the n-back task as secondary task that parametrically varies memory workload. A virtual driver model was created using the cognitive architecture. The model was simulated in the same situations as the human drivers. The activities of the cognitive architecture as indicator of cognitive workload increased with increasing difficulty of the n-back task. To relate model workload to human driver workload, we compared it with neurophysiological workload measures based on functional near-infrared spectroscopy (fNIRS) brain activation as a complementary measure.
