Envisioning Systems Using a Photo-Essay Technique and a Scenario-Based Inquiry

In this paper, we propose a requirements elicitation method (ailed PRESPE (Participatory Requirements Elicitation using Scenarios and Photo Essays). PRESPE enables participants to reflect upon their personal experiences when using systems and create photo-essays based on this reflection. The participants can then analyze these experiences by forming design concepts, envision scenarios by imagining contexts of use, and create artifacts by sketching these scenarios. We also describe a PRESPE case study that envisions future use of mobile phones.
