  Family mementos document events shaping family life, telling a story within
and between family members. The elderly collected some mementos for children,
but never recorded stories related to those objects. In this paper, in order to
understand the status quo of memento storytelling and sharing of elderly
people, contextual inquiry was conducted, which further helped us to identify
design opportunities and requirements. Resulting design was defined after
brainstorm and user consultation, which was Slots- Memento, a system consisting
a slot machine-like device used by the elderly and a flash drive used by the
young. The Slots machine-like device utilizes with the metaphor of slots
machine, which integrates functions of memento photo displaying, story
recording, and preservation. In the flash disk, the young could copy memento
photos to it. The system aims to facilitate memento story sharing and
preservation within family members. Preliminary evaluation and user test were
conducted in evaluation section, the results showed that Slots-Memento was
understood and accepted by the elderly users. Photos of mementos were easy to
recall memories. It enabled the elderly people to be aware of the stories of
the family mementos, as well as aroused their desire to share them with family
members. Related research methodology includes contextual inquiry,
brainstorming, prototyping, scenario creation, and user test.
