在本文中，我们描述了一种设计和评估普适系统的新方法。我们已经招募了30名参与者，他们将在3年内参与跨学科的普适计算项目Cityware。该队列的选择是为了代表年龄和技术能力的广泛组合，以便增加在Cityware中开发的系统和应用程序评估的生态有效性。我们将讨论一些技术和方法，这些技术和方法是我们维护这群参与者的结果，并说明他们的数据是如何提供给Cityware研究和应用程序的。虽然征聘和维持这样一个队列的费用相对较高，但以这种方式产生的结果的深度、丰富和有效性方面的好处被认为是巨大的。我们从新设计的潜力、可以收集的数据类型和城市参与的角度来讨论这个问题。
In this paper, we describe a new methodology for the design and evaluation of pervasive systems. We have recruited a cohort of 30 participants who are engaging with an interdisciplinary pervasive computing project Cityware over 3 years. The cohort has been selected in order to represent a broad mix of ages and technological abilities so as to increase the ecological validity of evaluation of systems and applications developed in Cityware. We discuss some of the techniques and methods that we have been able to employ as a result of maintaining this group of participants and illustrate how their data feeds into Cityware studies and applications. While the costs of recruiting and maintaining a cohort such as this are relatively high, the benefits in terms of the depth, richness and validity of results produced in this way are considered to be significant. We discuss this in terms of the potential for new designs, the type of data one can collect and engagement within the city.
