Design Forum

Associate Professor Omar Sosa-Tzec was invited to give a talk and a workshop about delightful design and user experiences at the 2025 Lilly Design Forum. Sosa-Tzec introduced his design delight framework, comprising six experiential qualities: engagement, surprise, liveliness, cuteness, serendipity, and reassurance. Dr. Sosa-Tzec used the fortune cookie to walk the audience through these qualities and how they help shape delightful products and experiences. He also urged designers at Lilly to consider delight as an essential element in living a happy and flourishing life and to recognize that a user's experiences are intertwined and, therefore, the delightfulness of a product or service represents an aim but not a formula.
