Sketching can be used as an effective communication tool. It allows people to visually communicate narratives, relationships, systems, ideas, instructions, and changes over time. Sketching improves memory retention, attention span, organization, and comprehension compared to only using words. Different types of sketches communicate information like charts, calendars, plans, and maps or provide instructions through signs, manuals, and labels. Sketching is also used to develop ideas for stories, designs, fashion, architecture, and more. Overall, sketches can visually convey thoughts, emotions, opinions, and other information in a concise manner.
