Alterego is designed to be a new version of the Six Thinking Hats mind tool by Edward de Bono. Alterego is a wearable device with three components, similar to a bracelet. As soon as a user picks up the objects they will light up with their own unique color, signaling that they are on. The three colors each have a purpose and code, to help guide the user to adopt different mindsets for evaluating ideas: green = optimistic, red = pessimistic, blue = moderator. This thinking behind this method is that it forces users to think outside their comfort zone and evaluate ideas in a balanced, unbiased manner—an essential skill for productive ideation.
