RE-DEFINING THE SYSTEM BOUNDARIES OF HUMAN-CENTRED DESIGN

Abstract Most services and products are designed in response to the needs, desires or expectations of humans. A variety methodologies grouped by term Human-Centred Design (HCD) have been deployed formalise improve this process, ranging from user-centred participatory practices. However, approaches’ consideration is primarily limited individuals their respective space time. To examine these system boundaries detail address potentials for adaptation, paper reviews dominant HCD methodologies, categorises them highlights characteristics. Further, concepts related fields studied potential contributions HCD. This results a proposed re-definition integrating spatio-temporal impacts on humans through an extended social, environmental economic scope. The different approaches varying impact assessments exemplarily applied case study urban mobility, particular human-centred, scenario-based design approaches. described methods kept generic ensure applicability across various domains practice.
