The purpose of this introductory paper is to provide some overview of and background to the issues that were raised at the Augmentative and Alternative Research Seminar in conjunction with the First Regional AAC conference on 23 February 2004. A group of 45 AAC researchers and professionals convened for one day to discuss some basic research issues in AAC. This paper highlights themes and perspectives that emerged from the research seminar discussions.
Literature reviews and discussion are used to provide a historical perspective on some of the issues raised. Two focus areas were identified for the purpose of this introductory paper; firstly, terminological issues that arose and secondly common themes that emerged during the paper presentations, discussions and/or written papers. Terminological issues include a brief description of the field of AAC for the benefit of those readers who might not be familiar with the field, whereafter the discussion focuses on the use of the term "complex communication needs" as referring to individuals who use AAC, the differentiation between symbols, signs, symbols sets and systems as well as the terms verbal and nonverbal, pre-linguistic and non-symbolic. The common themes throughout the papers include a discussion on the importance of context in communication, the chicken and egg question (i.e., comprehension and production), issues on multimodality, descriptive strategies for understanding interaction, and the use of typical interaction as a framework for understanding AAC interaction.
In reviewing some of the issues in the field it is apparent that the issues we face now and those faced in AAC during earlier years are similar, however the need for a stronger database is apparent as the approach towards evidence-based practice becomes more prominent. The move to understand the nature of complex relationships in interaction is highlighted, for example, the multiple associations between environment, comprehension as well as the use of multi-modal communication. Whilst it became evident that most of these issues need further research in relation to typical interactions, applications to the field of AAC are most challenging.
这篇介绍性论文的目的是概述并提供背景信息，以阐述在2004年2月23日与第一届地区性辅助与替代沟通（AAC）会议联合举办的辅助与替代研究研讨会上提出的问题。45名AAC研究人员和专业人士齐聚一天，讨论AAC中的一些基础研究问题。本文突出了研究研讨会讨论中出现的主题和观点。
通过文献综述和讨论，为提出的一些问题提供历史视角。为这篇介绍性论文确定了两个重点领域；首先，出现的术语问题，其次是在论文展示、讨论和/或书面论文中出现的共同主题。术语问题包括为那些可能不熟悉该领域的读者简要描述AAC领域，之后讨论聚焦于“复杂沟通需求”一词用于指使用AAC的个体，符号、手势、符号集和系统之间的区别，以及言语和非言语、前语言和非符号等术语。贯穿各论文的共同主题包括关于沟通中情境重要性的讨论、“先有鸡还是先有蛋”的问题（即理解与表达）、多模态问题、理解互动的描述策略，以及将典型互动用作理解AAC互动的框架。
在审视该领域的一些问题时，很明显我们现在面临的问题与AAC早年面临的问题相似，然而随着循证实践的方法变得更加突出，建立更强大数据库的需求显而易见。强调了理解互动中复杂关系本质的进展，例如环境、理解以及多模态沟通使用之间的多重关联。虽然很明显这些问题中的大多数在典型互动方面需要进一步研究，但应用于AAC领域极具挑战性。
