With the development of society and the progress of the times, the category of architectural design continues to expand, and the connotation of architectural design continues to expand too. In order to fred a balance between the subjective value system and the objective value system, an architect must have a value orientation based on his own values and construct a judgment mode that what kind of value orientation is the lust choice for architectural design and how to guide and regulate the value orientation. Based on the concepts and principles of architectural design and value orientation, this study constructs a mode to solve the problem of priority value orientation in architectural design which is based on the analysis of the factors influencing architectural design.

1Since the middle of last century, the world has entered consumer society. Decided by consumerism, hedonic consumption has got popular. Hedonic consumption makes people be personalized during consumption and brings a high degree of prosperity in consumption. But at the same time, for the materialization logic in consumerism, people has been enslaved by substance and involved in the vicious circle about unlimited demand for substance, which brought a series of problems in consumption. Nowadays, sharing consumption is rapidly developing, which leads to the change of consumption values. The application of big data in the consumer area, through bringing ＂big data sense＂ and solving information barrier, is one of the most important reasons to cause the change. This change can help to establish a fair consumption environment and harmonious consumption relations, which will make the economic development faster and better

在虚拟现实(VR)的视觉体验中,一方面,VR环境通过模拟“环绕光”向感知者显现的方式能影响感知者的自我在场知觉;另一方面,感知者视觉活动所具有的可逆性,能使其知觉到自身与VR环境之间的共在关系。这两方面的耦合共同促进了“虚拟在场”现象的形成。“虚拟在场”在现象学存在论的意义上表明人与数字化虚拟环境构成了一种肉身性的“交织”存在关系。这种存在关系意味着人在世存在的生存论结构能在虚拟维度得以延伸,以至于指向着可能的虚拟生存,而这种可能性已在“元宇宙”中初见端倪。

虽然技术的工具理性促成了城市化进程,但是也造成了城市的蔓延、城市人文肌理的断裂、城市差异性受限、日常生活依赖技术性的设置和城市空间隔离等城市现代性问题。这是城市技术人工物功能意向的符号化、价值意向的工具化、伦理意向的等级化的必然结果。为此,从超越本质主义和理性主义的立场出发,从发展智慧科技、涵养城市文化、提升城市技术人工物共享价值3个方面对城市日常生活进行改造,来克服由于技术理性而带来的城市现代性问题。

实现真实现实与虚拟现实交互穿越临界点是元宇宙领域构建的第一个入口平台,因此,穿越临界点意味着真实现实与虚拟现实交互以及元宇宙自身系统等所有事情之间都互相连接,达到现实本身的“奇点”。胡塞尔的内时间意识理论,以点性现在揭示内时间意识既构成原感觉单独的个体,又使个体在整体连续中受到内在秩序统一。而时间位置此时的“现在”作为时间意识的唯一性,成为视觉感觉领域一种内在秩序的先天朝向。受此启发得出,穿越奇点的根本在于真实现实与虚拟现实相融合于内在统一秩序中。而其中人尽管受控于数字化技术,但其自身意识无论如何都不会如斯蒂格勒所说因受数字化化技术影响而被改变,永远都是以其自身系统与客观对象建立联系,构建自身统一。

人工智能的关键特征是采取最优行动,而该特征会直接导致人工智能难预知性和风险性的属性,进而使其社会负面影响呈现出早期难预测和后期难控制的特点,此称为人工智能的科林格里奇困境。而单一的技术向度解决科林格里奇困境对人工智能技术的特性提出了严苛要求,导致其适用范围的局限性。鉴于此,我们引入了现代伦理方法:预知性技术伦理(ATE),并用行动者网络理论对其责任分配问题进行了补充。在技术设计阶段渗透价值并映照社会行动者网络以解决人工智能社会后果在前期难预测、后果难纠正的问题,进而达到消解人工智能科林格里奇困境的目标。

运用现象场进行意识分析,是胡塞尔现象学的特色,多年来一直未有人单独作为独立的研究加以总结和阐释。以现象场研究为核心,对胡塞尔的意识理论研究进行了重新梳理和提炼,为意识把握现象做了更系统、深入地论述,在胡塞尔现象学研究中拓展出一个新角度。依据胡塞尔的内时间意识发生机理、本质统一体的"相符统一性"躯体自定位功能,纯粹意识的客观化统握等意识构成理论,阐述现象场在意识构成中的作用与意义,从而得出结论:现象场是意识的意向性构成的功能性活动"场所",是意识存在的给出方式;作为直观体验奠基于意识的自明性、确证性,实现着意识的统握功能。
