### Deriving the Design Framework
#### 3.1.2 Establishing a Design Strategy  
To establish a specific design strategy, in-depth interviews were conducted based on the collected design elements. A daily life journey map for female seniors was developed according to the content of the in-depth interviews. The in-depth interview questions focused on daily life, loneliness, and activities or contents that they found rewarding. Five people individually participated in in-depth interviews, and Table 2 lists the subjects discussed. The interviewees in this round also provided prior consent for participation, and a telephonic interview was conducted if a face-to-face interview could not be arranged due to COVID-19. Accordingly, two face-to-face interviews were conducted with elderly adults on 25 April and 2 May 2020, and one face-to-face interview was conducted with a care worker on 29 April. Two other interviews were conducted via telephone. All the recorded files were transcribed and documented. Four researchers analysed transcribed data. \begin{table}

Table 2: Characteristics of second interviewees. Senior 1 (86 years old, female) agreed to have her daily life filmed and shared with others. She also said that she wanted to share a video of her singing with others, as she enjoyed singing. Senior 2 (89 years old, female) was greatly discouraged by having nothing to do while living in a nursing home recovering from a fall. Further, throughout the interview, she mentioned that if she recovers and returns home, she wishes to cook for her children in her kitchen as before. Even though Senior 3 (76 years old, female) mentioned her experience of reading books to the elderly in the elderly welfare centre, she said that the grandmothers who appear on video service platforms (e.g., YouTube) are \"smarter\" than her. She also mentioned that she could do well with her own experience if she created the content of reading books to people. Meanwhile, Senior 4 (75 years old, female) showed the physical and psychological burden of participating in service contents such as reading fairy tale books due to the physical changes she had experienced. However, she talked about \"growing plants\", her hobby, which she felt rewarded her while she was at home, and she delighted in talking about the flowerpots that were in full bloom at the time of the interview. A nursing care worker (66 years old, male) shared the experiences of the elderly in the nursing hospital. Further, he said that they formed a bond with other elderly people through \"song\", mentioning that these moments gave the elderly a sense of stability in their living environment as well as enjoyment. The elderly in welfare centres usually spend the daytime participating in recreational activities such as dance, magic, and singing. However, all programs were suspended due to the COVID-19 pandemic. Through interviews with the elderly living in a nursing hospital and a care worker, it was identified that the elderly's residence style and ability to perform daily life activities varied depending on whether they lived in the community or the facilities. The fact that they had a low chance of interacting with other elderly adults in the facility due to COVID-19 also affected them. Based on these findings, we narrowed down our service targets to older adults living in the community.
