WRL Research Report 2000 / 3 Rock ’ n ’ Scroll is Here to Stay

Using the example of an electronic photo album, a novel user input method for digital appliances is introduced. Based on tilting and gesturing with the device, the Rock ’n’ Scroll input method is shown to be sufficient for scrolling, selection, and commanding an application without resorting to buttons, touch screens, spoken commands or other input methods. User experiments with a prototype system showed that users could quickly learn how to operate such devices and offered some insight into their expectations. These positive results, combined with improvements in the sensor technology, encouraged us to incorporate this input method into an experimental handheld system.
