This document discusses shared situation awareness and its importance in the design process. It involves recognizing patterns in changing situations to anticipate what may happen next. Sources that can indicate trends include films, music, subcultures, and exhibitions. The design process involves observing raw data sources, identifying patterns to form hypotheses about how situations may unfold, and testing hypotheses. Different types of trends like mainstream "Fords" or niche "Trafalgars" are discussed. Designers must look in emerging areas like London neighborhoods or China to identify early patterns and current influences. Examples like Zelda Fitzgerald's ring inspiring Kate Moss's party or androgynous styles trickling down show how influences spread across media.
