Many remembering activities nowadays include technology, such as a phone used to take and view photos, a laptop with a file structure or search engine to help find documents, and a social media app to post and share messages to represent someone’s identity. In Human-Computer Interaction and related fields more and more research goes into learning how to design for remembering. This chapter will be divided into two parts, the first will focus on motivations to study design for remembering (the WHY), where the second part will focus on how design for remembering using memory technologies can support people (the HOW).
