可穿戴传感器可以为自由生活人群的健康行为提供可靠、自动化的测量。然而，如果没有可观察到的行为确认，这些措施的有效性是不可能的。参与者在使用第一人称视角的以自我为中心的可穿戴相机时表示不舒服。我们认为，与以自我为中心的相机相比，将相机安装在不同的身体位置，以不同的镜头方向，可以提供设备记录功能，从而减少监视和社交不适。我们称这种类型的相机为“活动导向”，因为它们被设计用来捕捉特定的活动，而不是佩戴者的视野。我们对24名参与者进行了三种相机设计的实验，收集了参与者在野外佩戴这些设备时的体验定性数据。我们提供了一个模型，解释导致社会存在和社会耻辱增加的因素，因此，给佩戴者带来社会和监视上的不适。佩戴者试图通过改变自己的行为或放弃设备来减少这种不适，这会威胁到对真实行为观察的有效性。我们讨论了设计的意义，并提供建议，以帮助减少社会存在和耻辱，以提高在野外用相机观察的有效性。
Wearable sensors can provide reliable, automated measures of health behaviors in free-living populations. However, validation of these measures is impossible without observable confirmation of behaviors. Participants have expressed discomfort during the use of ego-centric wearable cameras with first-person view. We argue that mounting the camera on different body locations with a different lens orientation, gives a device recording affordance that has the effect of reducing surveillance and social discomfort compared to ego-centric cameras. We call these types of cameras "activity-oriented" because they are designed to capture a particular activity, rather than the field of view of the wearer. We conducted an experiment of three camera designs with 24 participants, collecting qualitative data on participants' experience while wearing these devices in the wild. We provide a model explaining factors that lead to an increase in social presence and social stigma, which, therefore, create social and surveillance discomfort for the wearer. Wearers' attempts to reduce this discomfort by modifying their behavior or abandoning the device threatens the validity of observations of authentic behaviors. We discuss design implications and provide recommendations to help reduce social presence and stigma in order to improve the validity of observations with cameras in the wild.
