This study aims to derive the effect of road traffic noise perception by the visual and aural information through a laboratory experiment. To verify the result more precisely, ME(Magnitude Estimation) and SD(Semantic Differential Method) evaluation on the effect of visual and aural effect were carried out by 43 university students. As the result, up to 10% of psychological reduction effect was shown under the 65dB(A). As the noise level, it was analyzed that the vision affected about 7dB(A) and sound affected 5dB(A). However, if these two are given simultaneously, mainly sound affects to reduce the annoyance of noise and the vision next. Compared with the urban central circumstances, this effect(2dB(A) under 65dB(A) noise) was shown smaller than field test.

Recently, various researches have been attempted to effectively display pseudo-aural senses to the hearing-impaired or the deaf, using vibro-tactile stimulus as well as visual sense. Particularly, it is reported that as complementary senses to support the visual sense, tactile senses displayed by either speakers or vibration motors improve the reality sense significantly but do not nearly improve the emotional sense. Thus, in this study, the thermal sense is selected as another complementary sense to support the pseudo-aural sense display and it is investigated whether the thermal sense could generate a pseudo-aural sense or not. For this purpose, a thermal display module which could effectively display the desired thermal sense is implemented. Then, experiments have been conducted to subjects, which provide them with various types of stimuli combined with the aural, the vibrotactile, and the thermal stimuli along with the visual information. It can be confirmed, through statistical analysis on the data collected from experiments, that subjects could feel a pseudo-thermal sense closer to the real thermal sense which the normal subject feel from both the visual and the aural information, particularly either i) with the thermal stimulus along with the visual information or ii) with both the thermal and the vibrotactile stimuli along with the visual information than only with the visual information. Conclusively, it can be confirmed that the thermal stimulus applied to the skin of the subjects could play a role of effectively displaying pseudo-aural sense related to the thermal sense, as an complementary media for the pseudo-aural display.

Infants communicate their feelings and needs to the outside world through non-verbal methods such as crying and displaying diverse facial expressions. However, inexperienced parents tend to decode these non-verbal messages incorrectly and take inappropriate actions, which might affect the bonding they build with their babies and the cognitive development of the newborns. In this paper, we propose an aural-visual two-stream based infant cry recognition system to help parents comprehend the feelings and needs of crying babies. The proposed system first extracts the features from the pre-processed audio and video data by using the VGGish model and 3D-CNN model respectively, fuses the extracted features using a fully connected layer, and finally applies a SoftMax function to classify the fused features and recognize the corresponding type of cry. The experimental results show that the proposed system classification exceeds 0.92 in F1-score, which is 0.08 and 0.10 higher than the single-stream aural model and single-stream visual model.

Visual information and aural warning of independent aircraft survivability equipment increase the pilot workload and limit the effective countermeasures. For increase the aircraft survivability, Integrated design of survivability display and aural warning need to consider pilot intuitions. If pilot aware the threat by intuition, evade or escape from the threat using the countermeasures equipment, it will increase the survivability. This paper describe the design and verification of for Utility Helicopter survivability equipment.

In this paper, we design and implement an active perception system. The proposed active perception system consists of four parts : an active robot, an aural active perception part, a visual perception part and an association part.

This thesis presents an emotion-based contents player platform that can change its visual and aural components as user's emotions. It analyzes the emotion as pleasant, unpleasant, aroused, and relaxed based on the physiological signals and the user's active response. Accordingly. the system reorganizes graphical and aural stimuli, such as, light, color, sound, in real-time. It can be used to develop and show the emotional contents and also be applied for the systematic analysis to find out how the components would affect the emotion. This paper describes overall the system architecture and the implementations of the sub-systems, as well as the actual contents built on top of the platform.

Eisner emphasized the importance of problem-solving objectives and expressive objectives in addition to behavioral objectives, and communication through multiple modalities including linguistic, visual, aural, spatial, gestural modes. This study analyzes 'Libraries and Information Life,' a textbook developed for information literacy instruction, by dividing it into educational objectives types(behavioral, problem-solving, expressive) and multimodal modes(linguistic, visual, auditory, spatial, and gestural), and seeks to derive implications for setting educational objectives for information literacy instruction and developing textbooks. The textbook has four volumes for elementary low-grade, elementary high-grade, middle school, and high school levels. Educational objectives were extracted from the textbooks, and 3 librarian-teachers were engaged in the analysis of these objectives. The main findings and implications of this study are as follows. First, when looking at the types of educational objectives, the proportion of behavioral objectives was found to be excessively high, and there is a need to strengthen the proportion of problem-solving objectives and expressive objectives. Second, problem-solving objectives tend to overlap with behavioral objectives, indicating a need to develop problem-solving objectives with defined conditions and solution requirements. Third, expressive objectives concentrated in specific units need to be placed evenly in other units. Fourth, in the case of multi-modality mode, the proportion of the linguistic mode must be reduced, the proportion of the visual, auditory, spatial, and gestural modes must be increased, and it is necessary to set educational objectives with clear characteristics of each mode.

Mixed and augmented reality (MAR) refers to a spatially coordinated combination of media/information components that represent on the real world and its objects, and on the other those that are virtual, synthetic and computer generated including any combination of aural, visual and touch. The extensible 3D (X3D) is the ISO standard for defining 3D interactive web-based 3D content integrated with multimedia. In this paper, we propose a model to integrate live actor and entity that captured from Microsoft Kinect to be represented in Web-based mixed augmented reality world by using X3DOM by which X3D nodes can be integrated seamlessly into HTML5 DOM content.

This paper is an attempt to design and implement a multimedia title for the lesson of' Creatu Environment' which appears in the textbook of the second semester for the fourth graders. The title make the most use do multimedia features so that students my be able to reach the best result of activities. The title adopts the Cocktail program developed by Hite-Media Co. It is designed to resolve that are associated with sequential and letter-centered simplicity. As a result, students can interact on the other and the amount of their lessons. The title can effectively combines visual and aural (i. e. information to bring in motivations and participations in learning activities. This title is believed to help students to solve many classroom questions and to try individual learning. Finally, it is hoped that the title helps students to understand the ultimate go subject. 'Environment does affect the life of plants'.
