The basic idea of the paper is that the current approach HCI-design leads to too limited solutions to design-problems and that the solutions should be more open-ended. The author begins by presenting a review of the historical development of design, starting from designing things to specific functions. In principle this era meant designing objects to fit their use, rather than designing objects that were pleasurable to look at. The next step according to the author was designing from function to communication, meaning that the objects are often used as a way of communicating some message (e.g., traffic sign) and must therefore support the message. The last step is said to be the shift of design from communication to experience, meaning that the design would focus on the results of the communication, i.e., user experience. This stage addresses user needs, their desires and experiences in interaction design with the objective being to enhance and extend the way that people communicate, work, and interact.
The author continues by presenting the current approach in HCI-design, namely ‘fit-design’ that aims to maximize usability, utility, interpretation, understanding and experience. Fit-design suggests that including users in the design process can lead to better designs and that knowledge on users must be gathered in order to produce good designs. The author continues by criticizing this approach. He says that fit-design always means optimizing the design to a set of specific tasks that are based on the knowledge of the user. This might result in too limited designs that do not support any alternate tasks, i.e., the risk of designs not being open-ended.
The author claims that user-design is extremely risky, as this limits the intended target group. “A User is something that designers create”, meaning that the users do not actually exist until the object of use is accepted and used. The author continues that by limiting the possible users of the design we limit the resulting experiences.
The author criticizes the idea of designing for a specific use as well, as the ‘use’ does not exist until the object of use is presented. Basically the author says that we cannot address a specific use with design, rather we can predict its future uses. He addresses this issue further in respect of the object of use, with his main point being that objects have a tendency of being open-ended and can be used in various situations, especially when different functionalities can be incorporated into the objects (e.g., cell-phones or hand-rails).
The author suggest new approaches, such as backtracking to design of things from a different point of view, designing objects with users in mind. The approach seems to be simply that designers should not design to a specific use, rather leave the intended use as open as possible.
