Nendo credit card-sized phone, features three hinges folding over in the same direction.
The Nendo smartphone in its folded state is 54 mm by 86 mm. Like an inchworm, the phone makes use of its multiple joints to in effect slide sideways, and can be transformed only by the user’s one thumb operation.
Sliding one fold up exposes 40 mm of the screen with various functions, such as the time, call history, notifications, and even the music player interface, all available on the limited area.
Next, sliding the second fold reveals 80 mm of the screen as well as the camera, which the user might notice has simultaneously moved to the top of the device. This is a fitting configuration for taking selfies or video calls and other functions linking the screen with the front-facing camera. Unfolding the entire phone unveils a 7-inch screen with a unique, slender proportion.
In addition to playing videos with an operable side panel, the user may also enjoy the phone as a controller in game mode with panels on either side, in multitask mode with numerous apps displayed in a row, and panoramic photography mode in full screen.
The controls on the side of the phone are shaped like ellipses cut in half, functioning as two to four buttons, becoming small, semicircular buttons or combining into one large button as the folds slide up and down.
Further, the stylus ordinarily inserted in the phone may be taken out for use and the phone folded in half to give the user the feeling of writing in a notepad.
