在各种领域中的个人信息学应用越来越多地通过低成本的个人感测来实现。尽管应用程序捕获细粒度的活动以进行自我反思，但共享通常仅限于高级摘要。细粒度共享有潜在的优势，但也有潜在的危害。为了帮助研究这个复杂的设计空间，我们采用价值敏感设计来考虑是否以及如何共享细粒度的步骤活动。我们确定关键价值观和价值冲突，并制定情景来突出这些价值观。然后，我们设计了一组数据转换，旨在最大限度地提高收益，同时最大限度地减少详细共享的危害。其中包括一种新的方法来交互式修改细粒度的步骤数据，允许人们删除私人数据，并使用基序发现生成现实的替换数据。最后，我们对12名参与者进行了半结构化访谈，研究这些场景和转换。我们将结果提炼成一组细粒度物理活动共享的设计考虑因素。
Personal informatics applications in a variety of domains are increasingly enabled by low cost personal sensing. Although applications capture fine-grained activity for self reflection, sharing is generally limited to high level summaries. There are potential advantages to fine-grained sharing, but also potential harms. To help investigate this complex design space, we employ Value Sensitive Design to consider whether and how to share fine grained step activity. We identify key values and value tensions, and we develop scenarios to highlight these. We then design a set of data transformations that seek to maximize the benefits while minimizing the harms of detailed sharing. These include a novel approach to interactive modification of fine grained step data, allowing people to remove private data and using motif discovery to generate realistic replacement data. Finally, we conduct semi structured interviews with 12 participants examining these scenarios and transformations. We distill results into a set of design considerations for fine-grained physical activity sharing.
