Designing a mobile phone of the future: requirements elicitation using photo essays and scenarios

We report a case study of designing a mobile phone of the future, involving participatory requirements elicitation using a form of scenario-based design. Participants took photographs and wrote essays that illustrate their personal interests and perspectives on given themes. They then analyzed the photos and essays. They created scenarios and posed questions about the scenarios to envision contexts of future use. The participants produced novel design concepts and provided design insights even though they had no design training.
