A controlling device has a configurable key. An overlay, such as a sticker, is provided to the configurable key and includes an indicia representative of media content and machine readable data indicative of an identity of the media content represented by the indicia. A memory of the controlling device stores a correspondence between the configurable key and data indicative of a source of the media content. Upon activation of configured, configurable key, the controlling device uses select command codes from a library of command codes and the correspondence between the configurable key and the data indicative of the source of the media content to transmit one or more commands for causing one or more appliances to access the source of the media content.

A data input and/or operator control system, particularly a keypad, also a POS keypad, having a lower portion and an upper portion and also at least one printed circuit board and at least one retaining plate. Inside, one or more protective mat(s) made of an elastic material is/are preferably adhesively bonded to the printed circuit board. In this protective mat, the components of the printed circuit board are recessed to as small an extent as possible and air ducts are incorporated in order to ensure that the keys are ventilated in relation to one another.

There are provided a key information control system and control method of body keys of a display and a television set, which relates to the display field and is capable of eliminating the problem of pressing a wrong key when the user operates the body keys. The key information control system comprises: the body keys disposed on the display; a detection means disposed in a surrounding area of the body keys, and configured to detect a state of a user relative to the body keys; a determination unit configured to determine whether the user has intention to operate the body keys according to the state of the user relative to the body keys; and a key information display controlling unit configured to control key information of the body keys to be displayed at an edge of a display area of the display in the case that the user has intention to operate the body keys, to make a display position of the key information correspond to a position of the body keys.

An extendable cover for a portable electronic device including a first back panel having a first edge portion and a second back panel having a second edge portion. The first back panel and the second back panel being linearly slidable to move the first and second edge portions relative to each other along a sliding axis, wherein the first and second edge portions are opposite ends of the extendable cover along the sliding axis. The cover may include an electrical cable management arrangement having a rotatable hub disposed at the second back panel, and a hub-biasing mechanism coupled between the rotatable hub and the second back panel to bias the rotatable hub in a biased rotational direction to reel in a first electrical cable extending between the first back panel and the rotatable hub as the first and the second edge portions are moved towards each other.

A keyboard includes a processing resource and a memory resource storing machine-readable instructions to cause the processing resource to communicate, in response to the keyboard being in a computing device input mode, with a computing device connected to the keyboard, and communicate, in response to the keyboard being in a mobile device input mode, with a mobile device connected to the keyboard.

The invention relates to a device for control/command of a plurality of man-machine dialogue facilities which are linked in series in such a way as to form a network. This device comprises a wire interconnection block linked by a point-to-point link to each dialogue facility via a network of twisted cables.

A button module with vibration feedback and fingerprint sensing, a fingerprint sensing module for the same, and a control method for the same are provided. The fingerprint sensing module has a fingerprint sensing unit stacked on a vibration unit. When the fingerprint sensing module detects a fingerprint, the control unit or a host of an electronic device determines whether the fingerprint is authenticated. If it is not authenticated, the vibration unit is activated, so that the user realizes that the authentication is not passed in real time through the vibration. Then the user may quickly change another finger or move the finger's position to speed up the authentication process. This can prevent users from waiting to improve user experience.

A projection display unit and a function control method. The projection display unit includes: a projection optical system including an illumination section, a projection lens, and a light valve; and a detection optical system including an image pickup device, the image pickup device being disposed in a position optically conjugating with the light valve, wherein: the detection optical system is configured to detect whether an input operation is performed in a peripheral region of a projection region on a projection surface, and in response to detection by the detection optical system in the peripheral region, a specific function is caused to be executed.

An apparatus including a housing for coupling a keyboard to a tablet device through at least one respective electric interface and circuitry integrated in the housing, and a camera sensor integrated in the housing, the camera sensor positioned such that a central axis of a field of view (FOV) of the camera sensor is substantially parallel to a surface of the keyboard, the camera sensor further positioned to capture a plurality of images and to transmit the plurality of images to the tablet device through the respective electric interface and the electric circuitry. Related apparatus and methods are also described.

Embodiments are directed to an electronic device having a hidden or concealable input region. In one aspect, an embodiment includes an enclosure having a wall that defines an input region having an array of microperforations. A light source may be positioned within a volume defined by the enclosure and configured to propagate light through the array of microperforations. A sensing element may be coupled with the wall and configured to detect input received within the input region. The array of microperforations are configured to be visually imperceptible when not illuminated by the light source. When illuminated by the light source, the array of microperforations may display a symbol.
