As HCI is applied in increasingly diverse contexts, it is im- portant to consider situations in which computational or in- formation technologies may be less appropriate. This pa- per presents a series of questions that can help researchers, designers, and practitioners articulate a technology’s appro- priateness or inappropriateness. Use of these questions is demonstrated via examples from the literature. The paper concludes with specific arguments for improving the conduct of HCI. This paper provides a means for understanding and articulating the limits of HCI technologies, an important but heretofore under-explored contribution to the field.
