This article examines the historical expansion and convergence of the fields of information behavior and human–computer interaction, primarily in terms of the philosophy underlying each field. Information behavior grew out of research in library service provision in the early 1900s, and human–computer interaction grew out of computer science and human factors engineering in the 1960s. While these two fields have had different origins, purposes, and discourses, in recent decades, they have begun to converge. In this article, we map this convergence and consider implications for the future of the information field. We conceptualize their scholarly paradigms as expanding circles, and we show that the circles of information behavior and human–computer interaction are expanding in terms of ontology, epistemology, and axiology—and moreover, they are beginning to overlap substantially. While the two fields continue to be largely separate in terms of scholarly discourses, we suggest that much could be gained by explicitly acknowledging their shared components. Some suggestions for this are discussed, and these are connected to the ongoing iSchool Movement.

本文主要根据每个领域的基础哲学来研究信息行为和人机交互领域的历史扩展和融合。信息行为源于1900年代初期对图书馆服务提供的研究，而人机交互源于1960年代的计算机科学和人为因素工程。尽管这两个领域具有不同的起源，目的和论述，但在最近几十年中，它们已经开始融合。在本文中，我们绘制了这种趋同，并考虑了对信息领域未来的影响。我们将他们的学术范式概念化为不断扩大的圈子，并且表明信息行为和人机交互的圈子正在从本体论，认识论和价值论的角度扩展，而且，它们开始大量重叠。虽然这两个领域在学术话语上仍然大体上是分开的，但我们建议通过明确承认它们的共同组成部分可以获得很多好处。讨论了一些建议，这些建议与正在进行的iSchool运动有关。
