Examples of the present disclosure describe systems and methods of providing sequential two-handed touch typing. In aspects, a client device may provide a touch-based input receiving application. The client device may include one or more sensors operable to detect the approach of a user's hand or touch-based tool. In response to a detection, the client device may determine input interaction information, such as aspects of the hand (e.g., right or left) and/or finger(s) being used. The input interaction information may be used to detect candidate keys and to provide a keyboard (or a portion of a keyboard) based thereon. In aspects, the provided keyboard or keyboard portion may be altered in response to a subsequent detection.

A default virtual interface is replaced by an adapted interface to an independent application. The adapted interface allows one (dependent) application to be accessed from within a second (independent) application. This allows, for example, a game application to be executed within a text messaging application. Output of the dependent application can be conveyed to the base application. The adapted user interface optionally includes a plurality of shortcut keys each represented by a different shortcut icon. One or more of the shortcut keys are optionally configured for sharing the dependent and/or independent applications with remote devices. Content shared via the virtual interface is optionally provided as a data stream and is optionally mapped to a social network, such sharing can be tracked across social networks.

The present disclosure provides a method for user interaction. The method includes pointing a first device having a sensor, towards a panel defining a physical area having a plurality of markers rendered thereon, recognizing an interaction area defined by the plurality of markers on the panel, and rendering a plurality of graphical user interface elements on the panel in an Input/Output viewport. The plurality of markers includes at least one of an object and a shape recognizable by suitable computer vision means. Further, the Input/Output viewport includes a spatial volume between the first device and the panel.

Provided is a wearable device including: an image sensor configured to sense a gesture image of a user setting a user input region; and a display configured to provide a virtual input interface corresponding to the set user input region.

A system that incorporates the subject disclosure may include, for example, device may perform operations for receiving a signal from an operational space associated with an accessory device, determining hand feature information according to the signal, accessing device location information associated with the computing accessory device, generating hand-device interaction information according to the hand feature information and device location information associated with the accessory device, and transmitting the hand-device interaction information to a virtual reality system, wherein the virtual reality system generates, according to the hand-device interaction information, a virtual hand and a virtual accessory device in a virtual reality image. Additional embodiments are disclosed.

Head worn computers may include two physically separated cameras mounted on a front surface that capture movements of a finger of the user of the head-worn computer. The head worn computer includes an image source adapted to display content in a see-through display of the head-worn computer, wherein the content is positioned to be perceived by a user as positioned on a surface proximate the head-worn computer. A processor of the head worn computer is adapted to develop a 3D model, based on the captured finger movements and the position of the content, describing an interaction of the finger with the content.

Provided are a method of receiving a Korean input by using an electronic apparatus and an apparatus. The method of inputting Korean, performed by using an electronic apparatus includes: displaying consonant buttons for inputting Korean consonants on a screen of the electronic apparatus; identifying a user's fingers; as a motion of a first finger is sensed among the user's fingers, selecting a consonant button corresponding to a location of the first finger; as the consonant button is selected, displaying vowel buttons corresponding to second, third, and fourth fingers among the user's fingers and being used to input Korean vowels on the screen of the electronic apparatus; and as a motion of at least one finger of the second, third, and fourth fingers is sensed, selecting at least one vowel button corresponding to the at least one finger.

An example system, including a projector unit, an all-in-one computer attachable to the projector unit, a camera communicatively coupled to the all-in-one computer, and a touch sensitive mat communicatively coupled to the all-in-one computer. The projector unit projects an image on to the touch sensitive mat, and the touch sensitive mat comprises an optical pattern used to track a handheld device interacting with the image.

An information processing apparatus includes an image obtaining unit configured to obtain an image obtained while imaging is performed by pointing an imaging unit towards a target surface, a distance obtaining unit configured to obtain, with regard to a plurality of areas constituting the image, information equivalent to distances from a position corresponding to a reference to surfaces to be imaged in the respective areas, and a recognition unit configured to use the information obtained by the distance obtaining unit with regard to a first area where a predetermined region of an object is imaged in one of the images obtained by the image obtaining unit and the information obtained by the distance obtaining unit with regard to a second area that is a part of the image and in contact with a surrounding of the first area to recognize an input state to the target surface by the object.
