This document summarizes a presentation about communicating new interactions from design concept to widespread adoption. It discusses using storytelling techniques like videos and mockups to envision interactions. It notes the importance of considering audience and level of detail. Prototyping is presented as allowing people to experience and provide feedback on interactions directly. Showing interactions through demonstrations, as Doug Engelbart did, can also be effective. Understanding is shaped by many factors like past experiences and popular media depictions. Interactions may be learned through social contexts like observing others. Creating interactive prototypes allows exploring dynamics of new interactions throughout the design process.
