Abstract: The disclosed system and method focus on automatically generating questions from input of written text and/or audio transcripts (e.g., learning materials) to aid in teaching people through testing their knowledge about information they have previously been presented with. These questions may be presented to an end user via a conversational system (e.g., virtual agent or chatbot). The user can iterate through each question, provide feedback for the question, attempt to answer the question, and/or get an answer score for each answer. The disclosed system and method can generate questions tailored to a particular subject by using teaching materials as input. The disclosed system and method can further curate the questions based on various conditions to ensure that the questions are automatically selected and arranged in an order that best suits the subject taught and the learner answering the questions.

Abstract: A computer-implemented method for designing a user-specific writing skill game is provided. The computer-implemented method comprises tracking a handwriting performance and generating a digital representation of the handwriting performance. The handwriting performance is performed by a user with a writing instrument.

Abstract: Systems and methods for lesson-based virtual reality (VR) welding training are provided. Broadly, the system creates a configurable, three-dimensional, virtual reality training environment displayed on a VR display. Using a handheld controller associated with the VR display, a student may select a welding lesson.
