If you have to explain what "haptics" is to a colleague or student, from now on just let them touch your new iPad HD. Delighted to see that the case is now closed on how effective haptic interfaces are in engaging the user/learner. Thanks to Apple, the research on haptics and widespread application to touch technology will quickly become available. I'm told by friends who work with iPhone programming that our work is a natural for that interface--especially now that the door has been opened in Cuperinto. Now, rather than buying a couple dozen research articles online, I'm going to get an iPad HD. Welcome to the future of pronunciation teaching. Keep in touch.
