    Affordance Feature Reasoning in Some Home Appliances Products
    (Cranfield University Press, 2009-03-31) Lim, J. S.; Kim, Y. S.; Rajkumar Roy; Essam Shehab
    Interactions between human and objects are made through specific features of the object, which are adequate to the task context. During interactions, the perceived features vary according to the context. Affordances are the messages that products provide and users perceive in such a way that user actions are naturally induced with the help of such messages. In this research, we define affordance features as structural elements providing affordances. We classify affordance features into functional, ergonomics, and informative aspects. For some home appliances, common affordances and affordance features are identified so that they can be used in designing other products.

    A product-service system representation and its application in a concept design scenario
    (Cranfield University Press, 2009-04-01) Kim, Y. S.; Wang, E.; Lee, S. W.; Cho, Y. C.; Rajkumar Roy; Essam Shehab
    Product-service systems (PSS) can give diverse value provision to consumers reflecting their individual needs, while also addressing multiple issues from manufacturers’ viewpoints. We propose graph and ontological representations of PSS, consisting of values, product and service elements, and their relations. PSSs may also be included as subsystems in a larger PSS. We illustrate a case scenario of PSS concept design starting from an existing product. Diverse requirements of stakeholders of the product life-cycle are transferred to persona generation. From state parameters of these personas, we identify operations to improve the personas’ values, and implement each operation as a sub-PSS.
