Abstract: This paper reports the experience of introducing and teaching Human-Computer Interaction (HCI) at the Faculty of Mathematics and Computer Science, from Babes-Bolyai University. We describe the theoretical content presented during lectures, the practical work the students have to perform, the involvement and the attitude of the students toward our approach in introducing them in the domain of Human-Computer Interaction. We also present the difficulties and challenges of introducing HCI between the mainstream computing related subjects our students are used to study.
Keywords: human-computer interaction, education in HCI.

Abstract: Poor web accessibility has negative social and economic effects as regards the inclusion of citizen and customers in the provision of online services. In this respect, accessible university websites is a precondition to ensure fair access to education to all young people. In this work, the focus is on the web accessibility for people with visual impairment. The objective of the paper is to present the results of a study exploring the website accessibility of 18 top-ranked universities in Romania. Evaluation has been done against the Web Content Accessibility Guidelines 2. 0 (WCAG2) in a tool-based approach The evaluation results show that overall, the web accessibility of university websites is low. None of the websites passed the first accessibility level. Most of the accessibility errors are related to the compliance with the first WCAG2 guideline: alternative text for non-text content.
Keywords: accessibility, university websites, WCAG2.

Abstract: Conversational agents are nowadays desired in many fields, mainly for task automation, but also for entertaining, therapy or other purposes. This report will introduce the main Dialogue Systems categories, along with some of the most successful frameworks and algorithms, reported as state-of-the-art over the last few years, with a focus on Goal Oriented (GO) chatbots. Due to the domain specificity, large accomplishments are the most difficult to attain, conversational agents being able, in general, to encompass some of the most problematic natural language processing tasks such as intent classification, information extraction, text generation. Similar to other subfields of artificial intelligence and machine learning, in this field we find the same vital role of large quantities of annotated data. Some of the research discussed here with significant input towards the industry tries to maximize knowledge gain over decreasing the number of annotated instances to be fed to the system as training data. I further carry forth our experiments on a telecom dataset, along with results, conclusions and future work.
Keywords: domain specific conversational, goal-oriented chatbots, dialogue systems, artificial intelligence, natural language processing.

Abstract: he paper explores the impact on player experience of the most common techniques used in computer games such as building blocks of game AI systems and procedurally generated content. The research uses extensive surveys of the most common techniques applied in practice, and then analyze their individual and combined impact on player experience. We observe player behavior through a series of playtesting sessions on an AI-based game prototype, with variations on each AI subsystem. The procedurally generated content related experiment presents a simple turn based tactical strategy game where the player must achieve the goal in different circumstances ranging from a simple grid to procedurally random generated levels.
Keywords: artificial intelligence, AI-based game design, systemic AI, computer game, procedurally generated content, player experience.
