死亡让肉体消亡，而媒介却保留了用户的行为痕迹，引发了逝者在场与生存媒介等新议题。本研究通过对15位丧亲者的深度访谈，对比分析了数码物与实体物对于记忆存储、情感唤起的影响，并探讨媒介连接逝者、沟通生死的“数字巫觋”意义。研究发现，数字痕迹具有遍在性、流动性、链接性，当其与平台逻辑、算法技术相结合，能够塑造“静态辉光”与“闯入式”的死亡文化，丧亲者将不可避免地偶遇逝者信息、触发回忆。数字痕迹还呈现出“脆弱”与“不朽”的矛盾性，当其脱离原生设备、被转移或存储至云端时，记忆的本真性也随之消失。在数字时代，是否保留逝者的数字痕迹成为关乎数字生命与情感联结的重要决策。

Death causes the disappearance of the body, but the media preserves a huge number of user traces, triggering a new issue of the presence of the dead, and existential media. This study conducted in-depth interviews with 15 bereaved individuals, analyzing the differences in memory storage and emotional arousal between digital and physical objects, and explore the role of the media as a digital wizard that can connect the dead and communicate between life and death. The study has found that the digital remains are pervasive, fluid, and linked. The combination of digital remains, media logic and algorithm recommendations create a static glow, intrusive culture of death, which inevitably leads to individuals encountering information about the dead and triggering memories. Digital objects have a contradiction between immortality and fragility. When the dead's information is detached from their native device and uploaded to the cloud, the authenticity of digital memory is also erased. In the digital age, the preservation of digital traces has become an important decision related to the survival of digital life and emotional bonds.
