According to various embodiments, there is provided a method for identifying a user input in a user input device, the method including: detecting edges in an output signal generated by a switch in the user input device; identifying a first-to-second-state edge as being indicative of a transition from a first state to a second state; counting down to a first rest period upon identifying the first-to-second-state edge; before completion of the counting down to the first rest period, restarting the counting down upon each detection of a further edge in the output signal; detecting a second-to-first-state edge in the output signal that occurs after completion of the counting down to the first rest period; and identifying the second-to-first-state edge as being indicative of a transition from the second state to the first state.

A remote controller unit is provided. The remote controller unit may include a navigation keypad area that includes one or more navigation keys. The one or more navigation keys may be configured to move a cursor on a display device associated to a computing device or select one or more user interface items on the display device. The remote controller unit may include a fingerprint input component arranged in the navigation keypad area. The fingerprint input component may be configured to capture a plurality of fingerprint frames of a user in response to the navigation keypad area being touched by the user to move the cursor or select the one or more user interface items on the display device. The fingerprint input component may be a fingerprint input transducer or sensor.

A letter input method using a touch screen allows an input action of a user to be recognized using basic slip actions in four directions perpendicular to each other and consecutive slip actions expansively consecutive therefrom, and a consecutive slip action is configured as a combination of actions slipping in a direction not overlapping with a former slip direction. Thus, each slip action may be clearly distinguished to fundamentally solve problems such as erroneous input, duplicated recognition caused by gestures (slips) performed at a border line, erroneous recognition or the like, thereby greatly improving the efficiency in inputting letters and also realizing an action recognition algorithm more conveniently and easily.

According to one embodiment, an electronic device includes a character input controller. The character input controller displays a software keyboard including a set of input areas. Each input area of the set includes objects each representing a character. The set of input areas is arranged adjacent to one another in a first direction. The character input controller moves an active input area in the first direction or in a second direction opposite to the first direction, in response to a first operation or a second operation, and changes a character of an active object displayed in the active input area into another character in the active input area, in response to a third operation or a fourth operation.

A display device is provided, which includes a jog switch which performs a moving operation in a plurality of directions and a push operation, a display unit which displays a first user interface (UI) for adjusting a channel or a volume of the display device or a second UI for adjusting other functions of the display device in accordance with a first operation of the jog switch, and a control unit which adjusts a selected function of the display device in accordance with a second operation of the jog switch in which is performed in a state where the first UI or the second UI is displayed. The jog switch is formed to project for a predetermine height from a surface of the display device, and thus a user can find the jog switch easily and promptly even is the jog switch is obstructed from view.

Various examples of the present invention relate to an apparatus and a method for displaying data in an electronic device. A method for performing operations in an electronic device, comprises the steps of: displaying a circular user interface on a screen, wherein the circular user interface includes a circular arrangement of numbers, characters, special characters and/or icons in selected orders; detecting the first rotation of a wheel by using a sensor; determining whether the wheel is stopped during the pre-selected time period after the first rotation; selecting one from the numbers, the characters, the special characters, and/or the icons; and rotating or rearranging the circular arrangement on the screen in response to the determination that the wheel is stopped during the selected time period such that the pre-designated or proposed one among the numbers, the characters, the special characters and/or the icons is located at the selected location.

A single-hand interdigit-coordinated mobile keyboard input device has a chassis configured to conform to human fingers with a plurality of articulating finger frames connected adjacent to each other, a plurality of user input elements, a processing device, and a signal transmitter. The plurality of user input elements is connected around the chassis in order to capture flexion, extension, adduction, and abduction movements of the plurality of articulating finger frames. The processing device interprets signals received from the plurality of articulating finger frames into desired output communication elements such as text characters. The signal transmitter sends the interpreted output to a computing device.

A display device is provided, which includes a jog switch which performs a moving operation in a plurality of directions and a push operation, a display unit which displays a first user interface (UI) for adjusting a channel or a volume of the display device or a second UI for adjusting other functions of the display device in accordance with a first operation of the jog switch, and a control unit which adjusts a selected function of the display device in accordance with a second operation of the jog switch in which is performed in a state where the first UI or the second UI is displayed.
