As a result of the demographic change, the population of the older adults within our society increases steadily. If done right, information and communication technology offer great potential benefit for older users. Thus, we focus on a human-centered design approach for aging (HCD+). This Paper describes the development of an input component for the Historytelling project, a cooperative interactive platform for older adults to connect life stories with historic events and appreciate the potential for older adult’s life experience. We conducted a task analysis based on requirements for the Historytelling project and developed a high-fidelity prototype which was tested with eleven older adults. The prototype was valued highly overall but still had minor usability issues. Thus, we could show that a rather complex task such as telling a life story with various multimedia objects can be executed by older adults if they are integrated into the design process from early on.
