Welding headwear comprises one or more image sensors, processing circuitry, and a display. The image sensor(s) are operable to capture an image of an unpowered weld torch as the torch passes along a joint of a workpiece to be welded. The processing circuitry is operable to: determine, through processing of pixel data of the image, one or more welding parameters as the torch passes along the joint to be welded; generate, based on the one or more welding parameters, a simulated weld bead; and superimpose on the image, in real time as the torch passes along the joint, the simulated weld bead on the joint. The display is operable to present, in real time as the torch passes along the joint, the image with the simulated bead overlaid on it.

Apparatus and methods for proactively and preemptively communicating with a user interacting with a software application are provided. The apparatus and methods may include an artificial intelligence/machine learning communication engine monitoring and tracking a user's interactions. The apparatus and methods may include the communication engine determining if the user requires further training, if the interaction is fraudulent, and pre-empting requests for information the user may commence. The apparatus and methods may include the communication engine creating and displaying training materials for the user to complete, revoking access if fraud is present, and proactively providing information before the user requests the information.

Example embodiments may relate to a system, method, apparatus, and computer readable media configured for monitoring a user performing various athletic movements and generating performance characteristics based on the data corresponding to such athletic movements. Users may also be encouraged to participate in athletic challenges or competitions against other users or groups of users. In addition, athletic movement data for multiple persons can be collected at a central location, and subsequently displayed to a user at a desired remote location, so that the user can compare his or her athletic activities to others.

Example implementations disclosed herein can be used to generate student user-specific customized hybrid educational documents. Such implementations include systems, methods, and devices for determining an attention span profile associated with a particular student user, and generating a custom educational document in response to the attention span profile. Student user experience feedback and test results determined from the use of the customized educational document can be assessed to update the student user's attention span profile. The updated student user attention span can then be used to update the customized educational document.
