本文从人的角度考虑了上下文感知系统应该关注的上下文定义问题。特别是，我们认为，情境中的人类方面无法通过技术手段感知甚至推断，因此情境感知系统不能简单地设计为代表我们行事。相反，它们必须能够以一种有效而不引人注目的方式顺从用户。我们的观点特别适用于这样的系统，即应用程序在体系结构上与控制其行为的感知和推理隔离。我们提出了一个设计框架，旨在指导人们思考如何适应环境的人类方面。该框架提出了四个设计原则，支持系统行为的可理解性和人类用户的问责性，以及在上下文感知系统设计中必须考虑的许多人类突出的上下文细节。
This essay considers the problem of defining the context that context-aware systems should pay attention to from a human perspective. In particular, we argue that there are human aspects of context that cannot be sensed or even inferred by technological means, so context-aware systems cannot be designed simply to act on our behalf. Rather, they will have to be able to defer to users in an efficient and nonobtrusive fashion. Our point is particularly relevant for systems that are constructed such that applications are architecturally isolated from the sensing and inferencing that governs their behavior. We propose a design framework that is intended to guide thinking about accommodating human aspects of context. This framework presents four design principles that support intelligibility of system behavior and accountability of human users and a number of human-salient details of context that must be accounted for in context-aware system design.
