I came across a blog post written by Frank Spillers titled: “The Science of Fun: How Fun Helps Improve Your Design”. He is a professional usability consultant who has worked with a number of large firms such as: Hewlett-Packard, IBM, Four Seasons, Logitech, and Microsoft just to name a few. In this blog post he shows how fun and a pleasant user experience can be used as a great usability tool. He outlines how you can design to the users’ emotions to make them more acceptable of your products. Why don’t you visit this blog post to see what I’m talking about?
