Disclosed are three-dimensional (“3D”) graphical user interface (“GUI”) elements for improving user interactions with a digital environment or a device by simplifying access to different data, functionality, and operations of the digital environment or the device. A 3D GUI element may include first visual information at a first position and second visual information at a second position within the 3D space represented by the 3D GUI element. In response to first input directed to the first visual information, the 3D GUI or system may perform a first action that is mapped to the first input and the first visual information within the 3D GUI element. In response to second input directed to the second visual information, the 3D GUI or system may perform a second action that is mapped to the second input and the second visual information within the 3D GUI element.

Digital signal processing circuitry, in operation, determines, based on accelerometer data, a carry-position of a device. Double-tap detection parameters are set using the determined carry-position. Double-taps are detected using the set double-tap detection parameters. In response to detection of a double-tap, control signals, such as a flag or an interrupt signal, are generated and used to control operation of the device. For example, a device may enter a wake mode of operation in response to detection of a double-tap.

Methods and apparatus provide for: generating image data for an application to be displayed on an output device; recording the image data generated by the image generating unit; and receiving operation information from an input device, where the recording includes storing the image data for an application for a predetermined period of time up to the point in time at which operation information is received during the receiving operation information from a specific input unit provided in the input device while displaying an application image.

Provided is an olfactory data sharing terminal including a receiver configured to receive olfactory data obtained by sensing an odor of an object through an olfactory sensor; a preference determiner configured to determine whether a user prefers the received olfactory data, based on a user olfactory function f.sub.user(x); and a display displaying a user preference for the received olfactory data.
