Usability is great but in an age where alternative options are only a click away is it enough? From the outside, you may have designed a shop window to display your products or services in the best possible light but what makes people take that critical step and commit to a purchase? Chris will cover the principles of Persuasion Design, or “Persuasion, Emotion and Trust” as Human Factors International defines PET Theory. They will present some real world examples of how companies are getting it right, and wrong in eCommerce.
