A portable computer has a host and a display screen. The host has an ergonomic keyboard. The ergonomic keyboard has a left-hand keypad, a right-hand keypad, a user proximal end and a user distal end. The left-hand keypad has a plurality of first key columns and a plurality of first key rows. The plurality of first key columns are in a first radial arrangement. The right-hand keypad has a plurality of second key columns and a plurality of second key rows. The plurality of second key columns are in a second radial arrangement.

An adjustable keyboard is provided. The adjustable keyboard includes keys, a housing to house the keys and a control system. The housing includes modifiable material between at least first and second ones of the keys. The control system controls the modifiable material to modify a positional relationship between at least the first and second keys.

A sinkable keyboard device includes a substrate, keycaps, a slide plate, and a driving member. The keycaps are above the substrate and capable of lifting and sinking. Each keycap is provided with a first guide member. The slide plate is below and in parallel with the substrate. The slide plate includes a long side and a short side connected to the long side. The slide plate is provided with second guide members respectively corresponding to the first guide members. The driving member is on the short side of the slide plate. The driving member includes a driving motor. The driving motor drives the slide plate to slide relative to the substrate along the long side to make the second guide members respectively against the first guide members to drive the keycaps to relatively sink.

An input method is provided by embodiments of the present invention, relating to the communications field, and invented to improve the input experience of a user. The input method includes: providing an input interface on a touch display screen, where the input interface includes a virtual soft keyboard distributed in a sector area around a lower left corner or lower right corner of the input interface; receiving an input instruction which is input by a user through the virtual soft keyboard; and displaying input information corresponding to the input instruction. An input apparatus and a terminal device are also provided by embodiments of the present invention. The present invention is applicable to a mobile device or a handheld device.

Separated keyboard and method for changing keyboard layout for each communication connection disclosed. The separated keyboard device includes a main keyboard unit connected to a digital processing device by wire or wirelessly and a sub keyboard unit physically separated from the main keyboard unit and connected to the main keyboard unit by wire or wirelessly.

The embodiments herein describe a mode of applications on the portable electronic device that improves single-handed operation of the devices. For example, the embodiments herein describe an ergonomic mode of an application that displays the graphical user interface (GUI) of the application in a bottom area of the display screen of the electronic device to allow the user to more easily interact with objects. The embodiments herein also describe an ergonomic mode of a keyboard displayed on the display screen of the portable electronic device. During the ergonomic mode of the keyboard, the keyboard is shifted towards a vertical edge of the display screen to allow a user to more easily reach keys of the keyboard that were previously unreachable without the user switching to two handed operation of the device or repositioning the electronic device in the user's hand.

A portable computer includes a display portion comprising a display and a base portion pivotally coupled to the display portion. The base portion may include a bottom case and a top case, formed from a dielectric material, coupled to the bottom case. The top case may include a top member defining a top surface of the base portion and a sidewall integrally formed with the top member and defining a side surface of the base portion. The portable computer may also include a sensing system including a first sensing system configured to determine a location of a touch input applied to the top surface of the base portion and a second sensing system configured to determine a force of the touch input.

An apparatus and method for arranging a keypad in a wireless terminal, and more particularly, to an apparatus and method for arranging a keypad in a wireless terminal to conveniently perform a key input in the wireless terminal, the apparatus including: a display unit for displaying the keypad in at least one of a right and left side on a screen of the display unit in a horizontal mode of the wireless terminal; and a controller for controlling the display unit to display the keypad in the right and/or left side on the screen of the display unit in the horizontal mode of the wireless terminal.

The invention concerns a method for providing a code input interface to a user by means of a twelve-keys arrangement consisted of three columns by four rows in a screen interactive device in which display on a screen changes and the user manipulates on the screen in accordance with the display of the screen. The method comprises: providing a code input region for inputting codes on the screen, the code input region comprising n key regions, the codes are divided into n number of groups, each group including m or less codes as members; allowing a flick manipulation of the user on the key region to m number of directions; determining which kind of flick manipulation and on which key region the flick manipulation is performed; and determining the code to be input according to the kind and the key region thus determined, wherein the m types of flick manipulations to the m directions include three or more flick manipulations on either one of upper and lower sides, and four or more flick manipulations to four or more directions are not used on either the upper or lower sides.

The present invention provides a key cap structure comprising a first key and a light transmissive body and a second key. At a side of the first key is formed with a bearing bevel and a side opening. The light transmissive body is disposed on the bearing bevel, the second key is disposed on the light transmissive body, and the first key and the light transmissive body and the second key are formed with different materials by injection molding. In this way, dissimilar materials of the key cap structure can be distinguished by colors or transparently, thereby achieving the efficacies of a variety of various materials and lighting effects.
