Technology is changing, which means the design processes supporting it must also change. Digital tools for user experience and interaction design are vital in enabling designers to create appropriate, enjoyable and functional human-computer experiences, and so will necessarily evolve alongside our technological development. This workshop aims to support the futuring of user experience and user interfaces, and will engage with stakeholders, practicing designers, researchers, students and educators in order to understand better the needs for next-generation design tools. We will envisage new forms of design tools that encourage best practice, for example, linking representations, analysis tools, just-in-time evidence, physicality, experience, and crucially, put context at the centre of design.
