User interfaces for virtual reality, augmented reality, and mixed reality display systems are disclosed. The user interfaces may be virtual or physical keyboards. Techniques are described for displaying, configuring, and/or interacting with the user interfaces.

A portable electronic apparatus including a first body, a second body, and a keyboard is provided. The second body is pivotally connected to the first body. The keyboard is disposed on the first body and includes a plurality of key structures. One of the key structures includes an elevating platform, a key cap, and a camera. The key cap is detachably mounted to the elevating platform, and the camera is mounted at one side of the key cap facing the elevating platform. After the camera is detached from the elevating platform together with the key cap, the camera is mounted and positioned to the second body together with the key cap, and at least a portion of the camera is exposed to the outside.

A multi-state keyboard function row is provided. A plurality of representations can be formed on an insert of the multi-state keyboard function row. An assembly of the multi-state keyboard function row can be configured to cause either a first set of the representations or a second set of the representations to be visible to a user. A brightness of the representations may also be controlled based on a brightness of ambient light.

Various systems, methods and apparatus are described, such as for engaging a touchscreen user interface. A first example includes a multi-function transceiver device having comprehensive and scalable mapping capabilities for use in a control environment. A second example includes a or the multi-function transceiver device being further equipped to perform specialized functions, such as Internet-based information-kiosk-type function(s). A third example includes a or the multi-function transceiver device, which may be Internet-connected, capable of being wirelessly and remotely controlled by a user via an app (e.g., via a teleoperation comprising a tablet, smartphone or mobile device (having said app)). A fourth example includes an apparatus performing one or a series of mechanical gestures (mechanical touch-induced control operations—such as single-touch, multi-touch, etc.) on a display screen and/or a user interface (UI). A fifth example includes technology that can turn any surface into touch-enabled controls for (wirelessly) controlling UIs, apps, etc. These are just some examples (as non-limiting embodiments).

Various systems, methods and apparatus are described for actuating a touchscreen user interface. A first exemplification comprises an intermediary-transceiver or mediating device; wherein said device is wirelessly capable of providing a scalable mapping interface to a touchscreen user environment. A second exemplification includes one or more conductive interfaces that are operatively coupled with a touchscreen device using at least one of a wireless interface and a conductive actuator at endpoint. Beyond the first and second exemplification above, other exemplary control modalities are also advanced and embodied by the inventor of the present invention.

Aspects of the present disclosure are directed to systems, apparatuses, and methods for the projection of images onto keycaps of a computer keyboard.

A hand-wearable device outfitted with data interface electronics is provided. The device is secured to its user by means of a comfortable material integrated across the top of the hand. The device includes a central palm section containing complex three-dimensional geometry and modular features for adjustable structures to house switch sensors. These structures account for each fingertip's location and orientation relative to the rest of the user's hand. Features to accommodate the comfortable securing material are built into the device to ensure the device does not shift or move around relative to the user's hand while being worn and operated. Integrated switch sensor and various power and transistor-based electronics allow the device to function and communicate with other computers and like devices. The device is worn on the left, right, or both hands simultaneously to enable access to the maximum number of potential sensor commands for a user.

An arrangement of alphabet keys is provided in a total of three rows. Two of the three rows have a total of nine keys each, and the other row has a total of eight keys. The vowel keys are grouped together in a vowel group having a symmetric shape in which an imaginary line extending vertically divides the vowel group into a left half and right half that is a mirror image of the left half. The vowel group traverses the three rows and at least two columns, and at least a portion of the vowel group is located at a center of the arrangement. The consonant keys are arranged in alphabetical order from left to right on opposite sides of vowel group. A vowel key in the vowel group is centered along the imaginary line to be at a midpoint of the vowel group in a horizontal direction.

A method and device for reading, writing, and communication by deafblind users is provided to enable such exemplary functions as word processing, text messaging, Internet access, and telephonic communication. By combining a chordic keyboard for user input with a self-scrolling Braille pad for reading Braille, embodiments of the invention enable the user's hands to stay in place on a user console rather than having to constantly switch back and forth between typing messages versus reading or checking for messages. This in turn enables duplex communication because the user can read or acknowledge incoming messages even while typing. It also reduces the dynamic complexity experienced in reading Braille because a body part used for reading Braille can remain constantly available for receiving messages simply by resting in place on the self-scrolling Braille pad without any swiping, thereby eliminating swiping gestures and the problem of timing them with the receipt of messages.

One embodiment provides a device, including: a mechanical keyboard; a key state component mechanically co-located with each of a plurality of keys of the mechanical keyboard, wherein the key state component changes state between at least actuated and unactuated; a processor; a memory device that stores instructions executable by the processor to: detect an input to change a state of the key state component for at least one of the plurality of keys; and change, responsive to the input, the state of the key state component for the at least one of the plurality of keys. Other aspects are described and claimed.
