Vision is a process in which the brain and eyes collaborate to enable sight by analyzing light reflected from objects. Vision is also the most crucial among the five basic human senses for recognizing environments. The eyes contain 70% of the sensory receptors in the body, and 90% of the information processed by the brain is visual. Currently, approximately 2.2 billion people worldwide have vision impairments. A recent study estimated that the global economic productivity losses due to vision impairment and blindness amount to approximately $410 billion. Additionally, as people age, their ability to control their vision declines, leading to presbyopia, which typically starts in their 40s. Since people heavily rely on vision in their daily lives, vision problems can significantly reduce the quality of life. Approaches to solving vision problems can be broadly categorized into visual prostheses requiring surgery, sensory substitution based on neuroplasticity, and smart glasses for presbyopia. We present the trends and future development prospects for three key areas of research: visual prostheses, visual substitution technologies, and smart glasses technologies. These areas are being explored with the aim of addressing visual impairments and blindness.

제품을 홍보하는 영상 광고에는 다양한 감각 요소가 사용된다. 시각적 요소와 청각적 요소를 활용한 영상 광고는 마케팅의 대표적인 수단이라 할 수 있다. 이와 같은 감각 요소를 활용하여 제품을 홍보하는 광고 영상은 로고 혹은 특정 이미지, 문구 등 시각적 요소를 지속적으로 또는 반복적으로 노출시키며 시청자에게 각인시킨다. 그러한 시각적 이미지는 브랜드 이미지를 효과적으로 심벌화하는데 효과적인 방법으로 사용되고 있다. 대부분의 자동차 브랜드의 광고 영상에서 시각적인 요소를 심벌화하였다면, 기아 자동차 K5의 광고 영상에서는 청각적인 요소 즉 사운드를 심벌화하여 K5만의 차별화된 광고 영상을 제작하였다. 본 논문은 청각적 요소를 심벌화한 기아 자동차의 K5 광고 영상을 타사의 자동차 브랜드 광고 영상과 비교 분석하였으며, 광고 영상 제작에 활용된 기법과 효과를 연구하였다.

목적 : 다감각 통합은 인지과제나 운동실행을 위해 다양한 감각정보를 사용하는 데 있어서 필수적인 처리과정이다. 특히 시각 및 체감각의 통합은 운동 행동의 주요한 요소이다. 본 연구는 감각통합 과정의 시간적 경로와 뇌의 담당 위치를 파악하기 위해 신경생리학적 연구방법을 사용하여 시각과 체감각의 통합과정과 관련된 뇌의 시간적 및 공간적 특성을 조사하였다. 연구 방법 : 실험실 상황에서 시각과 촉각 자극을 독립적으로 또는 동시에 제시하고 유발전위검사(ERP: Event-Related Potentials)를 통해 통합작용 시 뇌에서 일어나는 신경세포들의 전기생리적활동을 측정하였다. 이때 시각 과 촉각을 각각 제시하여 얻은 유발전위신호들의 선형합과 두 개의 자극을 동시에 제공하였을 시 발생되는 유발전 위신호를 측정하여 비교하였다. 결과 : 시각과 촉각을 독립적으로 각각 제시하여 얻은 유발전위신호(SUM)의 합과 두 개의 자극을 동시에 제공하여 얻은 유발전위신호(SIM)는 같지 않았다. 특히나 자극의 반대측인 오른쪽 일차체감각영역(C4)에서 SIM은 SUM 보다 특정시간대에 통계적으로 유의미한 차이를 보였으며, Bilateral parietal areas(P3, Pz, P4) 뿐만 아니라 일차 시각영역(O1,O2)에서도 두 조건간 추가적인 통합관련 신경활동전기신호에 의한 통계적으로 유의미한 차이를 나타내고 있다. 결론 : 뇌 속에서 2개 이상의 감각이 통합될 경우 이와 관련된 추가적인 신경세포활동이 일어나고 있으며, 이는 다 감각을 동시에 제공할 경우 뇌의 활동을 더욱 활발하게 촉진시키고 있음을 시사한다.

Multi-sensory systems, including the visual, somatosensory, and vestibular ones, are involved in maintaining standing balance. The organization of these sensory systems is as important as the efficiency of each individual system in maintaining optimal balance. The purpose of the present experiment was to investigate the developmental changes in static standing balance and sensory organization under altered sensory conditions. This study involved 64 children (from 4 to 15 years of age) and 17 young adults. The children were divided into four age groups: 4~6, 7~9, 10~12, and 13~15 years. Static standing balance was assessed with the one-leg standing test under four different sensory conditions: the children stood on a firm surface with (1) eyes open or (2) closed, and they stood on a foam surface with eyes (3) open or (4) closed. In balancing ability, the age groups exhibited significant differences. The function of sensory organization for balance control was poorer for the children than for the young adults. The functional efficiency of the somatosensory system of the children aged 7~9 years was at the young adults' level, and the visual function of the children aged 10~12 years had also reached the young adults' level. However, the functional efficiency of the vestibular system of children was significantly lower than that of the young adults, even at the age of 15 years. This may indicate that sensory organization and standing balance are still developing after the age of 15 years.

Background Infraorbital nerve dysfunction is commonly reported after zygomaticomaxillary complex fractures. We evaluated sensory changes in four designated areas (eyelid, nose, zygoma, and lip) innervated by the infraorbital nerve. This evaluation was conducted using the static two-point discrimination test and the vibration threshold test. We assessed the diagnostic significance of the blink reflex in patients with infraorbital nerve dysfunction. Methods This study included 18 patients, all of whom complained of some degree of infraorbital nerve dysfunction preoperatively. A visual analog scale, the infraorbital blink reflex, static two-point discrimination, and the vibration threshold were assessed preoperatively, at 1 month postoperatively (T1), and at a final follow-up that took place at least 4 months postoperatively (T4). The results were analyzed using a multilevel generalized linear mixed model. Results Scores on the visual analog scale significantly improved at T1 and T4. The infraorbital blink reflex significantly improved at T4. Visual analog scale scores improved more rapidly than the infraorbital blink reflex. Two-point discrimination significantly improved in all areas at T4, and the vibration perception threshold significantly improved in the eyelid at T4. Conclusions Recovery of the infraorbital blink reflex reflected the recovery of infraorbital nerve dysfunction. We also determined that the lip tended to recover later than the other areas innervated by the infraorbital nerve.

Immersion is a features of VR technology, and the most important condition for evaluating VR experience. With the improvement of VR technology, including the presentation accuracy of VR content, the degree of interaction is diversified, the user's immersion in VR equipment should not only be improved technically, but researched from the user's perception level. The paper defines two important factors, immersion and presence, in a participant's experience with a VR device. Although the current technology can already simulate the real environment information visually and audibly, the content of the VR environment is not enough for us to achieve a completely real experience. Based on the Flow theory of Csikszentmihalyi and the sensory immersion achieved by current technology, this paper proposes the key factors of how to achieve conscious immersion for users in VR media. We prove that immersion is an indicator of the true degree of sensory simulation of VR equipment and is the basis for the realization of flow experience. What really makes the participant feel a perfect experience is the content provided by the VR environment and gave participants a sense of presence, it is not limited to video or games. On the premise of the Multi-Sensory, Immersion, Interactivity and Imagination experience achieved by using virtual reality technology, combined with the content creation of flow theory, the interactive immersion achieved by users is an important method to realize the awareness immersion of VR equipment.

The purpose of our study is to clarify about the influence that the visual information gives to the brain activities when pressure exerted the abdomen by waist belts. The visual information means that the some different visual information is inputted it, and the brain activity is evaluated by Electroencephalogram(EEG) measurements. At the same time, we carried out the sensory tests and verified about the relations between the psychological stress and the brain activities. There was a difference in change in the power of the $alpha$ wave with the eyes opened between man and woman. from the result of the sensory test, in the case of under the condition in the darkness with the eyes opened, there was no change in the a wave with before the pressure and after the pressure. In the other cases, $alpha$ wave changed in the same way with before the pressure and after the pressure. In the case of the visible and the invisible in pressure place, $alpha$ wave changed in the same way with before the pressure and after the pressure, but there was a difference in value. From the above, it isn't recognized that the visual information is influencing a pressure sense but some influences are given to it to the brain activities.

We compared the electroencephalogram, blood pressure, and sensory evaluation inspectioni several color of Petunia hybrida to analyze the physiopsychological effects of a plant. Considering occipital is related to visuosensory field, green color is thought as mild visual stimulator unlike to pink color. The results are coincident with the well-known facts that green color is less stimulating color. It is also accorded with the sensory evaluation results that green color showed te feeling of blue and stable. In case of green color is showed the feeling of blue and stable. In case of green color the generatioin of alpha waves increased according to the increase color area. Therefore it is thought that green color helps decrease of visual stimulation and increase in visual stability. However it is thought that pink has less physiopsychological effects on human beings depending on area sizes than green has.
