The rapid change experienced in the field of Information Technologies makes the informatics more tangible in daily life. Today, it became possible to encounter with the informatics applications almost all the disciplines. As a matter of course, many informatics applications are put into the practice regarding the sports discipline. Because of the condition that the power of information processing has increased and the studies on wearable technologies in addition to the expert system design, augmented reality (AR) has become a topic which gains importance in the field of sports. There are many studies that are conducted with the aim of increasing the efficiency of physical activities done in many sports branches, ensuring a more fair management of competitions and providing the opportunity for spectators to watch the competitions in a more comfortable and efficient way. In this study; the information about the current augmented reality practices that are used in various sports branches has been given and the mobile and interactive augmented reality practices which are possible to be seen in future have been mentioned. In addition, there is an augmented reality practice which is designed with the aim of ensuring that the shoots of sports people who are interested in archery, are more stable and of ensuring that the trainings and exercises are more efficient by stating to the sports people whether he or she is in the right position for shoot which is called as T shape seen at the time of releasing the arrow.

Usability of computer games is essential for the competitive game development market. Heuristic evaluation is one of the frequently used methods for this purpose. In this study, heuristic evaluation of Guild Wars 2 was conducted. Heuristics that were specifically developed for computer games from the literature were extracted for the evaluation under five categories. These were ease of playability and learnability, decent visual design and adequate interaction with the player, adequate satisfaction level of game content, game play and game mechanics, adequate fictionalized and supportive game narrative and adequate communication components and socializing opportunities. Six evaluators evaluated the game based on the given heuristics. The participants reported some usability issues which should be resolved.
