An assemblable keyboard includes plural assemblable keys and a main control key. Each assemblable key can be triggered to generate a key signal. The assemblable key includes a pedestal, a key structure and a conductive structure. The main control key includes a key processor and a transmission interface. The assemblable key includes plural coupling structures with the conductive structure. Every two adjacent assemblable keys are combined together and electrically connected with each other through the corresponding coupling structures. After the key signal generated by each assemblable key is transmitted to the main control key, the key signal is further outputted to a computer host. The layout space of the assemblable keyboard is reduced. Moreover, the assembling flexibility of the keyboard is enhanced.

A method for controlling a control region on a display screen of a computerized system is presented. The method includes obtaining data from a touchpad. The data is associated with a position of a portion of the hand of a user when the user operates the touchpad. The method includes transmitting the data from the touchpad to the computerized device and analyzing the data in accordance with a model of a human hand. In certain embodiments, the method includes identifying different sets of virtual keys to be associated with the different fingers of the user's hand and generating a control region comprising the sets of virtual keys. In some embodiments, the method may include displaying the control region in a position on the display screen in accordance with a position of one or more fingers of the user's hand on the touchpad.

An electronic device is provided. The electronic device comprises a touch panel and a controller. The touch panel includes a touch layer, a sensing layer, and a light emitting layer. The touch layer includes a dielectric surface. The sensing layer is configured below the touch layer and configured to sense a touch operation on the dielectric surface to generate a touch signal. The light emitting layer includes a plurality of light emitting units. The light emitting layer is configured below the touch layer. The controller is electrically connected to the touch panel and configured to generate a control signal to turn on or off the light emitting units to generate at least a virtual key. A touch panel is also provided.

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.

One example embodiment includes a keyboard for providing back typing with a mobile device. The keyboard includes a keypad, where the first keypad includes a set of keys for input to a mobile device and a first hinge, where the first hinge is attached a first portion of the keypad and where the first hinge is configured to allow movement of the first portion of the keypad relative to the mobile device. The keyboard also includes a second hinge, wherein the second hinge is attached a second portion of the keypad and wherein the second hinge is configured to allow movement of the second portion of the keypad relative to the mobile device.

A mute-able input device with keystroke tactile feedback includes: a plurality of keys, each including a tactile structure and a sound-generating structure for respectively generating operational tactile feedback and operating sounds; a plurality of adjusting mechanisms, each including an adjusting portion corresponding to one of the keys; at least one switching unit including an operating portion and a switch member, the operating portion connecting the switch member and the adjusting mechanism, the switch member generating a switching signal involving a mode switching between different tactile modes or different sound modes for one or more keys. When the operating portion moves in response to a force, the switch member is triggered to achieve the mode switching; meanwhile, the adjusting portion moves to interfere with at least one of the tactile structure or the sound-generating structure along with the movement of the operating portion.

An input system includes a first base portion and a second base portion that each include a keying surface. A base portion manipulation mechanism couples the first base portion to the second base portion. The base portion manipulation mechanism includes a moveable coupling that is configured to allow relative movement of the first base portion and the second base portion into at least one of a tented orientation and a splayed orientation. A locking mechanism provides a biasing force that causes an engagement between portions of the moveable coupling that resists relative movement of the first base portion and the second base portion absent an unlocking force, wherein the locking mechanism is responsive to the unlocking force that overcomes the biasing force to allow relative movement of the first base portion and the second base portion into the at least one of the tented orientation and the splayed orientation.

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.

An input system includes a first base portion and a second base portion that each include a keying surface. A base portion manipulation mechanism couples the first base portion to the second base portion. The base portion manipulation mechanism includes a moveable coupling that is configured to allow relative movement of the first base portion and the second base portion into at least one of a tented orientation and a splayed orientation. A locking mechanism provides a biasing force that causes an engagement between portions of the moveable coupling that resists relative movement of the first base portion and the second base portion absent an unlocking force, wherein the locking mechanism is responsive to the unlocking force that overcomes the biasing force to allow relative movement of the first base portion and the second base portion into the at least one of the tented orientation and the splayed orientation.

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.
