With the obvious growth in end user computing and the accompanying wide range of characteristics which those end users possess, there is a growing need for support which takes into account both the user and the context of use. In re-examining Gruden's key focal points, while ever the interaction remained with a hardware or software focus, a single taskuser interface could be considered sufficient. Support for the user involved modification to either the hardware or the software predictable. However, if the focus and the effect of such modification was normally has moved to the work setting, the number of interfaces increases and support unpredictable. Indeed, support must be through only one interface becomes considered in terms of all interfaces. If, as suggested, the primary mandate of HCI is user support.
