Ricardo Sosa is an Assistant Professor at SUTD. The document discusses new rapid prototyping technologies that can aid in the creative design process. It explores how the representation of an idea, through sketches, drawings, models or prototypes, can influence the idea itself and the next idea generated. Representations allow designers to see issues or opportunities not evident in 2D sketches. The future may include using these technologies for usability studies, group ideation sessions, implementing multiple interaction modes, and refining digital models.
