摘要： Perceived crowding is one of the important evaluative factors for environment quality. As a result, understanding the levels of perceived crowding is highly valued in recreation. According to previous studies, the earliest way to measure perceived crowding is to use the 9-point Likert scale. The smaller the figure, the less the users feel crowded on the spot. However, there are also different methods used in those studies to discuss the relationships between user's perceived crowding and other variables;including on-site survey, mail survey, picture simulation or virtual reality (VR). Among those different methods, as the new technology, VR may be considered the an appropriate research tool for the front-country crowing studies. In order to eliminating the limitations imposed by previous studies on measuring perceived crowding and understanding the potential of using IVR technology to measure perceived crowding. We used three studies to discuss the difference between photos and IVR, the difference between on-site experience and IVR, and the difference between on-site photo and VE in IVR method. This study progressively proves that: 1) IVR was more sensitive than photo evaluation method, and 2) IVR was not different from the on-site experience. 3) When IVR is used for research, there was no difference between on-site photo and VE. The results suggested that IVR might be more close to real on-site perceived crowding than traditional photo method;and it is possible to use 3D simulations in IVR.

摘要： This article mainly selects the image data of 4 years, and establishes the corresponding coastline markings and extraction principles based on the field investigation. The specific method is to use the visual method to extract the shoreline of a province in four periods, and use the 908 shoreline method to make a more accurate assessment. The main data are length, location, and soil quality, and finally, the corresponding statistical analysis is carried out. The combination of virtual reality and rehabilitation medicine has long been the current mainstream trend, and the balance rehabilitation training system produced by the combination of the two has an excellent prospect in the future. China’s economy has developed rapidly in recent years, and people’s material living conditions have also been greatly improved. However, the current health status of young people has shown a downward trend, especially in some colleges, primary and secondary schools, and feedback from physical test data. In universities, the physical health indicators of young people are declining year by year. In response to this situation, we must make corresponding countermeasures. At present, China has developed a sports health management software and released it on the Android platform. It mainly uses Bluetooth communication to connect with corresponding health monitoring equipment. The architecture mainly uses spring, and focuses on the mvc programming idea. Use a server to store data on the server side. Using JAVA language to develop communication uses Http language. The ultimate goal of the system development is to improve the physical health of young people as a whole, and to achieve overall psychological and physical health.

摘要： 自“互联网+”概念被写入《政府工作报告》,上升为国家经济社会发展的重要战略以来。“互联网+”对电影产业链尤其是电影技术进行全面革新,在颠覆以往数字电影形态的同时,又对传统电影进行有益的补充。未来在“互联网+”的助翼下,中国电影有望突破单纯的票房依赖型初级发展模式,形成以版权经济为核心的大电影产业,同时在电影技术革新层面,势必会从传统2D电影升级到3D电影,尤其对新型的VR(虚拟现实)电影技术的发展带来不可估量的推动与影响。文章基于“互联网+”的视阈之下,考察VR(虚拟现实)技术的运用对传统的电影语言的各种革新范式,同时对VR(虚拟现实技术)在电影产业发展中的悖论进行哲学性思辨,观照“互联网+”视阈下VR(虚拟现实)电影技术的发展模式及走向。

摘要： 为区分大脑的情绪状态以及研究在不同情绪状态下的大脑半球不对称性,征选20名健康视听无障碍的受试作为实验对象,联合虚拟现实(VR)技术和脑电(EEG)监测,在不同的VR影片刺激下,采集受试脑电信号,提取各频段的平均功率谱密度,并计算大脑半球不对称性的参考指数,对比在不同情绪状态下各频段与各脑区下的参考指数。结果显示,相较于中性情绪,积极情绪与消极情绪在额区的半球不对称性指数均偏小,但在alpha频段,额区出现积极(0.130±0.227)、中性(0.058±0.240)、消极(0.006±0.130)依次递减的指数趋势,表明积极情绪下左侧额区更加活跃,且积极情绪与消极情绪两组间有具显著差异(P<0.05);而在其他频段中,额区的半球不对称性指数较为平均。此结果可为不同情绪的区分提供新思路,也为脑功能疾病以及心理疾病的判断和治疗提供新方法。

摘要： 随着社会科技的发展,建筑设计媒介也在不断变化与改变,从早期的“一维”语言文字到“二维”建筑图形,再到“三维”建筑模型。虚拟现实(VR)技术作为一种新的建筑视觉再现的数字化媒介,给人们对建筑设计过程的认识带来了巨大的影响,其对建筑材料、材质、肌理、光线变化与空间的真实模拟可以为设计师带来更直观的感受。虚拟现实不仅为建筑设计课程教学的发展提供了新的机会,而且也提供了比传统教学方法更有效的教学方法。将虚拟现实技术与博物馆建筑设计教学相结合,能够更好地提升学生设计素养,弥补传统设计类课程的缺陷。
