Interactive Processes of Language Use in Human-Computer Interfaces

9202458布伦南今年是为期三年的连续奖项的第三年。这项研究的目的是为了更好地理解人类语言使用与计算机系统的互动过程。这项研究的理论基础是，人机交互，就像人类交流一样，属于一种协调的行动，通过系统地交换理解的证据来进行。我们考察了两个过程：a)夹带，假设影响词汇选择；b)基础，假设设置适当反馈的水平和位置。心理学实验将使用模拟的语言和语音界面来检查1)什么变量影响人们的词汇选择，以及这样的系统如何适应特殊的语言输入，2)系统应该生成什么样的文本输出才能将自己呈现为连贯的对话伙伴，以及3)语音或语言界面应该提供什么样的上下文敏感反馈。其目标是促进自适应用户界面的设计，实现更健壮的错误处理，并使自然语言、命令和语音界面更易于人们使用。

9202458 Brennan This is the third year of a three-year continuing award. The goal of this research is to better understand the interactive process of human language use with a computer system. The theory underlying this research is that human-computer interaction, like human communication, falls into a class of coordinated actions that proceeds by the systematic exchange of evidence of understanding. Two processes are examined: a) entrainment, which is hypothesized to influence lexical choice, and b) grounding, which is hypothesized to set the level and placement of appropriate feedback. Psychological experiments will use simulated language and voice interfaces to examine 1) what variables influence the lexical choice people make and how such a system might adapt to idiosyncratic language input, 2) what kind of text output should the system generate to present itself as a coherent dialog partner, and 3) what kinds of context-sensitive feedback should a speech or language interface provide. The goals are to contribute to the design of adaptive user interfaces, to enable more robust error handling, and to make natural language, command, and voice interfaces easier for people to use.
