Teaching Interactive Media Design

In todays, computer-centered society, designing interactive media has emerged as a new profession. Interactive design is often associated with spread of computers as a communication and interaction tool. However, interactive design has been a staple of artists and designers for many centuries. We present a historical perspective upon interactive design and point out the close relationship of this field with different fields of art and design. We argue that interactive media design is a distinct and evolving field and that it is imperative to teach it as such. In this paper, we have adopted this perspective and detailed a new four-year under-graduate curriculum on interactive media design education. This curriculum stresses the various components of interactive media design and its close relationship with computer science. This revised version was published online in July 2006 with corrections to the Cover Date.

Research on Basic Design Education: An International Survey

This paper reports on the results of a survey and qualitative analysis on the teaching of ‘Basic Design’ in schools of design and architecture located in 22 countries. In the context of this research work, Basic Design means the teaching and learning of design fundamentals that may also be commonly referred to as the Principles of Two- and Three-dimensional Design. The body of knowledge associated with Basic Design may be regarded as part of the general theory of teaching and learning design as practiced in many design schools and which has its origins in the classical design schools such as the Bauhaus. In the author’s perception and practice, the pedagogy of Basic Design promotes a holistic, creative and experimental methodology that develops the learning style and cognitive abilities of students with respect to the fundamental principles of design. This includes an understanding of the elements of shape, colour, texture, light, and rhythm in a manner complementary but usually unrelated to the common design methods teaching approach. As is well known among design practitioners, including architects and industrial designers, a deep understanding of the purpose of these fundamental design elements and principles is still relevant to contemporary design practice. The main objective of the research described in this paper was to determine the status and development of Basic Design pedagogy in a significant number of contemporary design schools. On the basis of the results of two surveys conducted in 2001–2002, this paper will identify and illustrate interesting aspects concerning the programmes and organisation of courses delivered by teachers of ‘Basic Design’. This work will also survey the viewpoints of Basic Design teachers in elementary years of design courses and of those teaching design through projects during the subsequent years of the same courses. Interestingly, the design project teachers surveyed in this research expressed a desire to be more involved in the teaching of Basic Design fundamentals which indicates strongly that Basic Design principles are still relevant in contemporary design education terms as they have ever been and that more research is needed in order to better understand and apply the related pedagogy.     

Dasein Versus Design: The Problematics of Turning Making Into Thinking

Building on suggestions from the work of Martin Heidegger, a distinction is made between two ways of being in the world. One is associated with the unplanned particularity and care of Dasein, another with the planning and thinking-out of design; the former is characteristic of a more traditional way of life, the latter of contemporary life. Included are brief etymologies of `Dasein' and `design', along with some reflections on the two-fold history of design of internal structure and surface appearance (that is, of engineering and aesthetic design, respectively). The conclusion sketches out a problematics of engineering design as involving a disengagement from fundamental human experience, and suggests the need to discriminate between authenticity and inauthenticity in the world of design.

提升设计管理 促进品牌建设

优秀的设计不只是一种直接从设计师那里所购进的商品,同时也是通过良好的管理从企业内部产生出来的创造性资源。设计管理不是单纯的管理设计师,还需要管理企业内部的许多其他相关因素。笔者认为,在这样一个复杂的体系里,管理要紧紧围绕着品牌建设来开展,否则即便它是有效的也一定不是最高效的。此外,笔者从品牌建设的角度,提出了两点具体的管理建议,希望能通过增强品牌意识和部门间协作来影响设计师的设计,从而使设计师作出更具品牌价值的作品,进而为品牌建设作出一些贡献。
