With English used in so many geographically distinct regions differences arise in usage. Here Jim Sandhu's classic paper on "design for all" creates the path to the current global dialogue on Universal Design as applied to services not simply to built environments.
The design for all approach covers a range of meanings which are synonymous with - barrier-free, inclusive, transgenerational, universal design, etc. Another often quoted phrase associated with design for all is "designing for the broader average." This far the approach has focused mainly on the built environment and products. However, in the last few years there has been an increasing awareness that the approach is fundamental to the provision of public services through telematics and to a barrier-free Information Society. That is the main focus of this paper.The approach recognises that accessible systems, products, reliable information sources and environments can maximise choice and enhance the ability of the individual to live independently and to exercise citizenship proactively. Underlying this is the fact that although not everyone needs assistive technology or specialised products like wheelchairs, everyone but everyone needs good design whatever the context. Good design enables, whilst bad design disables, irrespective of the user's abilities. That in essence is what design for all is about in the context of public services.
