[UPDATE: Upon further reflection, this seems to be a student project created for the class, not research by Galletta himself. And as I said, it’s not clear how serious a test it was or what the methodology was. (I do note that the end credits list a “cast.” My bad for jumping to conclusions after reading this story.]
Professor Dennis Galletta has been teaching a summer course at Harvard on Human Factors in Information Systems Design. As part of it, he conducted some usability testing of the iPhone 4, Samsung’s Windows Phone 7-based Focus, HTC’s Android-based Thunderbolt, and RIM’s BlackBerry Storm. He had people who hadn’t used any of the phones try to make a call, add a contact, and send a text message, and videotaped their attempts to do so.
