自然主义移动环境中的受控实验
Controlled Experimentation in Naturalistic Mobile Settings
摘要：
在自然移动环境中的小型设备上进行受控用户实验一直被证明是许多人为因素研究人员的一项艰巨任务。困难的存在，尤其是因为模仿自然的小设备的使用遭受缺乏不引人注目的数据来指导实验设计，然后验证实验是自然进行的，在这里，我们使用观察数据来推导出一组协议和一个简单的验证清单，可以内置到任何控制实验的设计集中在一个小设备的用户界面。这些，已被用于一系列的实验设计，以衡量实验软件的实用性和应用。关键点是验证检查--基于观察到的400名移动用户的行为--以确认用户认为受控实验是自然的。虽然用户遵循的实验路线的设计是实验设置中的主要因素，但如果没有基于不引人注目的观察数据的检查验证，则无法确定设计为自然的实验实际上是按照设计进行的。
英文摘要：
Performing controlled user experiments on small devices in naturalistic mobile settings has always proved to be a difficult undertaking for many Human Factors researchers. Difficulties exist, not least, because mimicking natural small device usage suffers from a lack of unobtrusive data to guide experimental design, and then validate that the experiment is proceeding naturally.Here we use observational data to derive a set of protocols and a simple checklist of validations which can be built into the design of any controlled experiment focused on the user interface of a small device. These, have been used within a series of experimental designs to measure the utility and application of experimental software. The key-point is the validation checks -- based on the observed behaviour of 400 mobile users -- to ratify that a controlled experiment is being perceived as natural by the user. While the design of the experimental route which the user follows is a major factor in the experimental setup, without check validations based on unobtrusive observed data there can be no certainty that an experiment designed to be natural is actually progressing as the design implies.
