This panel will identify various ways Human-Computer Interaction (HCI) methods have been applied to health care. It will discuss successful and unsuccessful applications of HCI Techniques and discuss how HCI methods were modified to address the health care domain.

Decision aids are being built by several research organizations. However, as noted by Wohl (1981), relatively few decision aids are in actual use. Problems with decision structuring methodology and failure to consult users during aid development are two reasons for this. A more important reason is the lack of general interface design guidelines directed specifically at decision aid designers. Three aspects of aid-user interaction--decision contingency, decision emergence, and the aid-user relationship--are issues which cannot be addressed by the decision structuring portion of aids but which require careful consideration during interface design. The development of a decision situation taxonomy which accounts for these issues is advocated as the starting point for general decision aid interface design guidance.
