A keyboard device according to one embodiment includes: a box-shape body, comprising a first side-wall and a second side-wall arranged opposite to and is pivotably openable relative to the first side-wall; a support assembly, configured to be connected detachably to the first side-wall of the box-shape body such that the box-shape body is adapted to support the electronic apparatus; and a flexible membrane keyboard which is connected with an internal surface of the second side-wall of the box-shape body and switchable between an unfolded condition in which the flexible membrane keyboard functions as a keyboard of the electronic apparatus and a folded condition in which the flexible membrane keyboard is received within the box-shape body. The keyboard device of the embodiments of the disclosure may function as both a keyboard for the electronic device and a support, and is provided with a limited size so as to facilitate portability thereof.

A human interface apparatus comprising the steps of: receiving text input from a user; switching to input mode for pointing location information; receiving input for pointing location information from the user; and switching the human interface apparatus to a text input mode, wherein the text input area and the pointing location information input area have at least a part of the area in common.

A wireless keyboard module, portable electronic device and methods for charging and pairing a wireless keyboard module to a portable electronic device are provided herein. According to one embodiment, the wireless keyboard module includes a wired connector configured to electrically connect to a wired connector on a back surface of the portable electronic device when the wireless keyboard module is mounted onto the back surface of the portable electronic device. Upon connecting the wired connectors of the wireless keyboard module and the portable electronic device, the wireless keyboard module is configured to receive a charging signal from the portable electronic device and configured to transmit a pairing code to the portable electronic device across the wired connectors.

A method for controlling a device, including: determining a distance state between a keyboard and a terminal device, the keyboard is in communication connection with the terminal device; in a case that the distance state is a distant state, adjusting a state of a screen of the terminal device to a wake-up state, and obtaining a first position of the keyboard and a second position of the terminal device; determining an angle between the keyboard and the screen of the terminal device according to the first position and the second position; and adjusting a state of the keyboard according to the angle.

An adjustable keyboard having a number of keys (205) is formed in at least two segments (202, 203) which are mutually movable relative-to one another using a hinge or joint (206). Each of the segments (202, 203) of the keyboard has mounted thereon some of the keys (205). The adjustable nature of the keyboard reduces stress and discomfort to the user by reducing contortion to the user's wrists. More particularly, discomfort to the user caused by pronation of the wrists and/or ulnar deviation of the wrists is reduced. The hinge or joint (206) is in the form of a ball and socket-type joint with a locking mechanism, which preferably includes a pivoted handle (100), in the form of a lever, used for locking and unlocking the hinge or joint (206). The surface of at least one of the ball and socket of the joint define a plurality of recesses or a plurality of projections, to provide increased resistance to joint movement.

A human interface apparatus comprising the steps of: receiving text input from a user; switching to input mode for pointing location information; receiving input for pointing location information from the user; and switching the human interface apparatus to a text input mode, wherein the text input area and the pointing location information input area have at least a part of the area in common.

A keyboard with keys arranged in at least three distinct sections, left, right, and supplementary. The left and right sections include left and right sets of keys, respectively, that contain letters and other commonly used keys. The left and right sections are arranged at between 20 and 30 degrees relative to a perpendicular to the user direction, and between -20 and -30 degrees relative to the perpendicular, respectively. The keys in the left and right sections are arranged in non-staggered columns, and the supplementary section containing supplementary keys arranged at between -5 and -15 degrees relative to the perpendicular, with keys arranged in non-staggered columns. The keyboard having a substantially uniform total height that does not exceed 1 centimeter, and which is arranged to sit flat on a surface.

Embodiments of the present invention disclose a moveable keyboard lattice frame for a portable electronic device. According to one embodiment, the portable electronic device includes a display housing and a base housing. The base housing is attached to the display housing via hinge members and also includes a keyboard input area comprising of a plurality of input keys. Furthermore, a moveable keyboard lattice frame is formed within the base housing and includes key openings corresponding with positions of the plurality of input keys. Moreover, the keyboard lattice frame is configured to rise and lower based on rotational movement of the display panel and hinge members.

An external sheath attachable to an electronic display and input device or to a holder of an electronic display and input device, including: an open ended chamber which receives an end of an electronic stylus and has a sidewall, an open end at one end of the sidewall and a second end at an opposite end of the sidewall, and a slot in the sidewall of the chamber, wherein the slot includes a first slot section, a second slot section offset from the first slot section and a bridge slot joining a distal end of the first slot with a distal end of the second slot, wherein the first slot section includes an open end aligned with the open end of the chamber and the slot in the sidewall is configured to receive a locking post on a side of the electronic stylus.

A human interface apparatus comprising the steps of: receiving text input from a user; switching to input mode for pointing location information; receiving input for pointing location information from the user; and switching the human interface apparatus to a text input mode, wherein the text input area and the pointing location information input area have at least a part of the area in common.
