The iPod/iPhone greatly shifted the nature of our relationship to technology. These new devices allowed people to do many things on one device. People could listen to music, take photos, send emails, use maps, and play games. The iPod/iPhone was also small, so people could easily carry it around. Because of how easy it was to carry them around, people could have them on them at all times, making them a part of everyday life. People could be more social online, and share with other people easily. The devices were also designed to be easy for all people to use. The icons easily showed what the app was and the overall layout was simple. The iPod/iPhone introduced touch-based gestures, which greatly affected interaction design. People could tap, swipe, rotate, drag, and so on. These were new ways for people to interact with a device, and also something new for interaction designers to work on when designing things for the iPod/iPhone. The user interface had to be intuitive so that the user knew what kinds of touch gestures to make. The gestures also had to be consistent between apps so that it would be more intuitive.
