A writing instrument comprising a body having an axis, a writing tip, a reservoir and at least one visual mark being a specific mark for augmented reality applications, the at least one visual mark being configured to be hidden/visible when the writing tip is distant from a writing surface and to be respectively visible/hidden when the writing tip is in contact with a writing surface, at least a portion of the body being configured to allow the at least one visual mark to adopt two states, visible and hidden configuration.

A verification system or method for detecting whether a CPA device is in a pre-lock position or in a full-lock position relative to the housing based on a scan system's detection that a portion of a predetermined barcode or QR code on the CPA device and another portion of the predetermined barcode or QR code are separated from each other or joined together to form the predetermined barcode or QR code. The CPA device is fully engaged or in full-lock position or status with the housing when the scan system has recognized or determined that the portion of the predetermined barcode or QR code on the CPA device and the another portion of the predetermined barcode or QR code on the housing within a scan window are joined together to form the complete or full predetermined barcode or QR code.

A writing system that includes a reusable notebook including a sheet having a working surface. The working surface includes a printed code and an operative control. The writing system includes a writing instrument configured to capture images of the printed code and a computing device configured to communicate with the reusable notebook and/or the writing instrument. The sheet includes a surface coating over the working surface configured so that a writing material of the writing instrument can be removed by applying a dry ancillary device.

A writing system that includes a reusable notebook including a sheet having a working surface. The working surface includes a printed code including an operative control. The writing system includes a writing instrument configured to capture images of the printed code and a computing device configured to communicate with the reusable notebook and/or the writing instrument. The sheet includes a porous surface located in the working surface. A writing material of the writing instrument comprises solid particles having a particle size greater than a porosity of the porous surface.

Devices and methods use a processor, a scanner, and a display screen. The processor is used to recognize Braille characters within the field of view of the scanner. The processor is used to convert the Braille characters into text, and the display screen is used to display the text visibly.

A universal language assistive translation and interpretation system that is configured to verify and validate translations and interpretations by way of blockchain technology and smart contracts, multiple cross-format translation and interpretation blockchain validating and recording processes for verifying and validating cross-format translations and interpretations by smart contract and blockchain technology, and several validated cross-format translation and interpretation blockchain access processes for providing cross-format interpretations and translations of inter-communications between users regardless of ability or disability are disclosed.

A portable writing apparatus includes a writing instrument carriage to hold a writing instrument and an actuator system coupled to the writing instrument carriage to move the writing instrument carriage. A controller is electrically coupled to the actuator system, and the controller includes logic that when executed by the controller causes the controller to perform operations including: receiving input data including a user's handwritten characters; and controlling the actuator system to move the writing instrument carriage in response to the input data. The writing instrument carriage traces a shape of the user's handwritten characters.

One embodiment provides a method including: detecting, at a touch surface, at least two points of contact of a hand of a user; identifying, based on a configuration of the at least two points of contact, an input provided by the user as handwriting input; and displaying, on a display screen, the handwriting input, wherein the handwriting input is identified as being input at a location relative to the at least two points of contact of the hand of the user. Other aspects are described and claimed.

Features described herein generally relate to locating objects in a scene using optical pattern recognition. Images of a scene that include objects are captured and optical patterns associated with the objects are detected and decoded. Code data for the optical patterns can be matched to search parameters matching input search criteria. The images can be displayed along with a graphic that overlays at least one of the images to indicate that an object matching the search criteria is depicted in the scene.
