We describe the future technology workshop (FTW), a method whereby people with everyday knowledge or experience in a specific area of technology use (such as using digital cameras) envision and design the interactions between current and future technology and activity. Through a series of structured workshop sessions, participants collaborate to envisage future activities related to technology design; build models of the contexts of use for future technologies; act out scenarios of use for their models; re-conceive their scenarios in relation to present-day technologies; list problems with implementing the scenarios; explore the gap between current and future technology and activity; and end by listing requirements for future technology. The method has been used successfully with children and adults to explore new technology-activity systems, including interacting with digital photographs and informal science learning.
