Wearable Cameras (WCs) enable researchers to capture objective descriptions of what participants see and experience as they go about their normal lives. When studying interactions between individuals (e.g. between a parent and child), using multiple WCs can provide highly detailed descriptions of interactions with levels of ecological validity not possible with other methods. However, the use of WCs brings challenges too, and understanding these is key to developing and optimising these methods. We captured the challenges experienced by a variety of stakeholders, namely parents and a range of different researcher roles (academics, field-workers and data processors) involved in a large UK study exploring parent-child interactions using low-cost, off-the-shelf WCs. High among the challenges identified were difficulties caused when subjects are temporarily not in view in the video footage captured. This and other factors identified were used as criteria to select a new, improved WC. The new WCs reduced the time faces were not in view by 75%. We report this and the other challenges identified, and suggest how these can be used to guide and help optimise future studies of this kind.
可穿戴式摄像头（WCs）使研究人员能够捕捉参与者在日常生活中所看到和经历的客观描述。在研究个体之间的互动（例如父母与孩子之间的互动）时，使用多个可穿戴式摄像头可以提供高度详细的互动描述，其生态效度水平是其他方法无法实现的。然而，可穿戴式摄像头的使用也带来了挑战，理解这些挑战是开发和优化这些方法的关键。我们收集了各种利益相关者所经历的挑战，这些利益相关者包括参与一项大型英国研究的父母以及一系列不同的研究人员角色（学者、实地工作者和数据处理人员），该研究使用低成本的现成可穿戴式摄像头探索亲子互动。所确定的挑战中，排在前列的是在拍摄的视频片段中，当拍摄对象暂时不在视野中时所造成的困难。所确定的这一因素和其他因素被用作选择新型改进型可穿戴式摄像头的标准。新型可穿戴式摄像头使面部不在视野中的时间减少了75%。我们报告了这一情况以及所确定的其他挑战，并提出了如何利用这些挑战来指导和帮助优化此类未来研究。
