This website is an online resource dedicated to Worth Maps (WMs), a design tool modeling interactive systems as connections between elements. In a WM, chains connect systems-oriented elements (e.g., features and their qualities) to human-oriented ones (e.g., usage consequences, emotions, feelings, values, needs). As such, a WM represents the interactive system following different perspectives and highlights reasons for (not) buying, (not) learning, (not) using, and/or (not) recommending it.
