This research is the preliminary study for development of narrative contents for improving reading skills and behavior controlling capabilities of children with ADHD. Microsoft's Kinect, a non-contact motion sensing device, and NeuroSky's MindWave, a BCI device, are connected to Unity 3D engine to capture user's motion and brainwaves, respectively. The given narrative contents interactively respond to children with ADHD while they are reading the contents and performing the given tasks presented in the behavior training game system. This study examines whether the contents are suitable for the first and second grader children. For this, The interaction with the contents is first observed by five adults and two children. Then the system is tested by three ordinary first graders. During the experiments, the children easily figure out the given texts and do what the game contents drive for the player to react. All three kids concentrate on the reading contents without leaving their seats for average 37 minutes. This experiment shows that the contents are properly designed for the first and second graders in terms of reading speed, reading completion time, complexity level, and task performance. Based on this experimental study, the interactive narrative contents will be used to conduct full-scale experiments with children with ADHD.

This study was established the foundation with the expressing method on the context awareness platform by using Sensor of the Smart Phone(SP). The data were used for expressing emotions with different SP. The emotion of SP was influenced with the changing of the several variables generating real time and were determined by interacting a mix of emotion depending on the intensity and causality. First, the SP platform was analyzed, which constituted the situational awareness process that can express emotions. Second, a mathematical model for expressing emotion through the SP event design. Third, when SP have to acknowledge, assess, and respond to the current situation, emotional system is the situation immediately. The user's SP has sense as digitalized data and analysis of data on various sensors. In the point of this article, it was limited that building a two-dimensional table was established by cognitive evaluation, internal emotional state of structural regularities, and using the POMDP model number of the emotional state. In order to influence the emotional perception, the range of influence was limited. Using the tree structure of the way HSVI, the computed time was minimal for matrix operations. Last, the compensation policies were interlocked with the blood type. Designed in advance for optimum algorithms derive scenarios. Using the proposed processing methods, digitized data were applied with SP sensor information. To determine whether the right set of circumstances in order to express appropriate emotion, it was established with the numerical system.

Low-resolution voxel models are widely used in many computer games such as CrossyRoadTM and MinecraftTM and in many block games such as LegoTM. We present a multi-scale voxelization algorithm that abstracts a complex polygonal model to a low-resolution voxel model. Our scheme is distinguished from other voxelization schemes in the point that our scheme controls the level of abstraction according to the complexity of the model. We present a two-stage algorithm: in the first stage, we build a rough voxel model, which is carved to fit the target model in the second stage. We empoly an OpenGL-based slicing algorithm to build a rough model, which is constructed in twofolds. The exterior and interior of the model is constructed separately and merged to complete the rough model. In the second stage, we compute the silhouette of the input model and carve the rough model to improve the completeness of the final result. We test our algorithm for various polygonal models including famous animation character models to prove the excellency of our scheme.

For the 3D game visual effects, the deferred rendering can only consider only the scene image resolution regardless of the scene complexity. Therefore, it is effective in processing realistic visual effects using many geometric buffers as multiple render targets. This paper uses the deferred rendering for the 3D game visual effects such as dynamic lights, specular, shadow, motion blur, and water shading. The 3D game supporting deferred rendering is developed to evaluate various 3D rendering effects with variation of the screen resolution in terms of the rendering speed and PSNR image quality. The performance results show that the rendering speed of the 3D visual effect techniques with 1280x960 resolution is average 56.0% better than that with 640x480 resolution. Also, the average PSNR is getting better as the screen resolution gets higher. The PSNR of the 3D visual effect techniques with 1152x864 resolution is average 30.9% better than that with 640x480 resolution.

Recent studies have shown that during the playing of violent online games, it is not increased aggression but rather alleviation in aggression that is critical in determining whether playing gaming has positive outcomes on the venting of aggression. Drawing from the aggression catharsis perspective and gaming research, we extend this line of investigation by exploring whether gaming results in a decrease in aggression, across a wide variety of games. Using data from a survey of 771 online game users in Korea, we examined the associations among Therapeutic Catharsis Seeking, Game Self-Efficacy, Big Five Personality Traits, Game genre (violent or nonviolent), Daily online gaming time, and Demographic variables. Results showed that therapeutic catharsis seeking and game self-efficacy decreased user aggression. Neuroticism negatively affected aggression while agreeableness enhanced the degree of aggression regardless of game genre. These findings have important implications for the use of gaming as a mood management tool.

Action recognition technology has many application fields including gaming, human-computer interaction, security, virtual reality, etc. The technology has recently advanced and simplified by the introduction of real time depth cameras. The most famous depth camera, Kinect, has shown its success in human action recognitions by supervised learning methods.
