The present invention is directed to a keyboard having a plurality of components that can be releasably attached to one another to enable expedited customization of the keyboard to a desired configuration. The keyboard includes a base and a plurality of keys. The keyboard may also include a plurality of adapters configured to be releasably attached to the base and/or the keys. One of the adapters is low-profile adapter, while another is a high-profile adapter. As such, the same keyboard can quickly and easily be customized from a low-profile keyboard to a high-profile keyboard, and then again to a low-profile keyboard. Additionally, various adapters may be releasably secured to the keyboard to create other visual appearances, including adapters having different colors, lighting effects, and the like. The adapters can be installed without use of tools and without disassembling the entire keyboard.

The present disclosure provides a keyboard, including: a keyboard body; at least one physical key disposed on the keyboard body; at least one virtual key projection device connected to the keyboard body and configured to present, by means of projection, an image of at least one virtual key in a projection area outside the keyboard body; and a click detection device configured to detect whether a finger clicks on the projection area and determine on which virtual key the finger clicks in response to that the finger clicks on the projection area.

The invention discloses a glasses waistband-type computer device, comprising a waistband body, wherein the middle of the front of the waistband body or other parts of the waistband body is detachably installed with a smartphone, and the front of the waistband body is further provided with a left keyboard located on the left side of the waistband wearer's navel and a right keyboard located on the right side of the waistband wearer's navel; the left and right keyboards are connected to the smartphone in a wired manner or a wireless including a Bluetooth manner. During man-machine interaction, the user wears a waistband so that the left keyboard is located to the left of the navel and the right keyboard is located to the right, to form a waistband keyboard. The invention is novel in structure, convenient to use, easy to carry, and can provide a good man-machine interaction mode.

Embodiments of this application provide a method and a system for generating a note. The method includes: detecting, by an electronic device, to-be-stored content selected by a stylus on a touchscreen of the electronic device; controlling, by the electronic device, a target device to store the to-be-stored content, where the target device is the electronic device and/or the stylus; and outputting, by the target device, the to-be-stored content. In the embodiments of this application, a storage function of the electronic device and/or the stylus is used to output the to-be-stored content required by a user as a separate note, which facilitates convenience for the user to read key notes and improves user experience.

A keyboard with key rows in a traversing linear row arrangement that intermesh with the linear row immediately above and/or below, with alternating inverted tapering offset keys. This allows keys to be kept in order while giving each key a less narrow and more broad profile to allow a wider area for the fingers to strike, while not decreasing the number of keys on a line or widening the keyboard and allowing for a more elongated height keyboard over all. This is to make the keyboard more suited to and targetable by human fingers and better use of the finite surface area of the keyboard.

A keyboard (110) includes a base board (116), keys (112), pitfalls (120) and a mode control mechanism (118). The keys (112) include cups (1124), and the mode control mechanism (118) may switch the keyboard (110) especially the key cups (1124) between different modes. In case that the keyboard (110) is not in use, these cups (1124) can be received in the pitfalls (120) to reduce the profile of the keyboard (110). In case that the keyboard (110) is to be used, the keys (112) may be raised up and arranged on the base board (116) in order to enable long keystroke and provide good typing experience.

In an aspect, a first controller module of a mobile device controller can be engaged with a first side of a mobile device of a user. A second controller module of the mobile device controller can be engaged with a second side of the mobile device. One or more mobile device controller characteristics associated with characteristics of the mobile device controller can be transmitted from the mobile device controller to the mobile device. A client application on the mobile device can be modified by a first data processor based on the one or more mobile device controller characteristics. The modified client application can be provided by the first data processor to the user in the mobile device, and the user can interact with the modified client application using the mobile device controller. Related systems, apparatus, techniques, and articles are also described.

A base unit for a keyboard is presented. The base unit has a substantially rectangular layout. The base unit includes an equipment portion, formed so that it can be equipped with a plurality of key switches for the keyboard. The equipment portion is arranged on a first side of the base unit. The base unit further comprises at least one coupling portion for mechanically coupling the base unit to an accessory module for the keyboard. Each coupling portion includes a first coupling feature and a second coupling feature. The first coupling feature is arranged on the first side of the base unit, and the second coupling feature is arranged on a second side of the base unit facing away from the first side. Each coupling feature is arranged parallel to a long side of the base unit continuously between narrow sides of the base unit. The first coupling feature is formed for positive locking with a first mounting feature of the accessory module. The second coupling feature is formed for positive locking with a second mounting feature of the accessory module.

A portable device (e.g., a wireless device such as a cell phone) is provided with a flexible keyboard and a flexible display screen. Such flexible components may be stored in the housing of the portable device when not in use. The flexible display screen and flexible keyboard may be expanded from the housing when the flexible components are utilized by a user. Non-flexible display and input components may be provided on the exterior of the portable device such that the device may be used, in some form, while the flexible components are stored. In one embodiment, a portion of the flexible display (or flexible keyboard) may be utilized when the flexible display (or flexible keyboard) is stored in said first housing.

A keyboard module pivotally connected to an electronic device is provided. The keyboard module comprises a bottom plate, a plurality of keys, a keyboard frame and a hinge structure. The plurality of keys are disposed on the bottom plate. The key includes a keycap and a support member for connecting the keycap to the bottom plate. The keyboard frame includes a plurality of openings to expose the keycaps. The hinge structure pivotally connects a display module of the electronic device with the keyboard frame or the bottom plate. When the display module rotates to drive the keyboard frame (or the bottom plate), the keycap moves relative to the keyboard frame (or the bottom plate). An electronic device including the keyboard module is also provided.
