Synthetic environment equipped with user interfaces intuitive for direct 3D shape modification by non-designer stake-holders was proposed as a collaboration tool for design concept communication in dynamic prototyping of product design in early stages of the design process. After a survey of 3D user interaction techniques for SE, a simple user interface(More)
Complex systems, like surgical robots, are designed by engineers. It is very difficult for them to determine the different needs and desires of all stakeholders. Especially when designed from scratch, end user input is essential in creating a system that has added value, is user friendly, and can be easily integrated into practice. For the development of a(More)
This paper aims to illustrate that the dominating rational-analytic perspective on the Fuzzy Front End (FFE) of innovation could benefit by a complementary sociointeractive perspective that addresses the social processes during the FFE. We have developed a still fledgling socio-interactive framework blending existing knowledge of the FFE with theories from(More)
Application of virtual reality technology within the product design processes can offer more than only a tool for analysis; it also offers opportunities for intended users to synthesize conceptual designs themselves. Within the virtual environment's constraints-set and managed by the designer-users can experience usage scenarios, define designs, and assess(More)
While it is commonly claimed that users of participatory design projects reap benefits from their participation, little research exists that shows if this truly occurs in the real world. In this paper, we introduce the method and results of assessing the participants' perception of their personal benefits and the degree of participation in a large project(More)
More and more consumer products are used in situations that are characterized by varying users, user characteristics, environments and purposes. This increase of the 'dynamics' of use situations is caused by technological developments. The ongoing trend of automation of services results in an increasing number of products that are used by a wide variety of(More)
This paper explains the possible uses of scenarios in product design. A scenario classification is proposed as a framework to create, use and reuse different types of scenarios in a product design process. Our aims are threefold: (1) to obtain a better view on the extent to which scenarios can be useful to a product design process, (2) to identify in which(More)
