"The development of all experiences must create solutions to problems of information creation, interaction, and, of course, sensorial media (the visual, audible, tactile, and other sensory displays that form the solution that people experience. Issues of understanding and meaning (information) and usability and appropriateness (interaction) are cerebral solutions that are only expressible with very sensory components. However, the real problems--and the most interesting solutions--lie in these cognitive processes and not in the beauty of the finished experience. This isn't so say that beautiful experiences aren't important, but beauty without purpose is, ultimately, meaningless."
