Understanding the needs of a variety of distinct user groups is vital in
designing effective, desirable dialogue systems that will be adopted by the
largest possible segment of the population. Despite the increasing popularity
of dialogue systems in both mobile and home formats, user studies remain
relatively infrequent and often sample a segment of the user population that is
not representative of the needs of the potential user population as a whole.
This is especially the case for users who may be more reluctant adopters, such
as older adults.
In this paper we discuss the results of a recent user study performed over a
large population of age 50 and over adults in the Midwestern United States that
have experience using a variety of commercial dialogue systems. We show the
common preferences, use cases, and feature gaps identified by older adult users
in interacting with these systems. Based on these results, we propose a new,
robust user modeling framework that addresses common issues facing older adult
users, which can then be generalized to the wider user population.

本文探讨了针对年龄在 50 岁及以上的用户进行的对话系统用户研究，发现了老年用户在与这些系统交互时的共同偏好、使用案例和特征差距，并提出了一个新的、健壮的用户建模框架，以解决老年用户面临的常见问题，并推广到更广泛的用户群体。
