Shape-matrix geometric instruments having numerous applications including, but not limited to, anti-counterfeiting, graphical passwording, games, and geometry education. A shape-matrix geometric instrument is a manufacture and/or a method whose design is based on a shape-matrix that, in turn comprises a set of building blocks that are N-dimensional polytopes. Corner shapes are positioned in or near the interior corner spaces of at least ones of the shape-matrix building blocks. At least ones of the corner shapes differ from others in at least one property or aspect including, for example, geometric shape, orientation within the building block, and one or more surface “finishes,” such as color, shading, cross-hatching or real or apparent texture.

In one aspect, A computerized method for implementing a virtualized training session user interface (UI) with respect to a production software UI includes the step of providing a production software application. The method includes displaying a guide on a production software UI. A workflow and a tutorial content of the guide is determined dynamically using one or more specified machine-learning algorithms. The method includes displaying the guide as a set of images with a virtual lab placed on top of each image of the guide. The method includes receiving a user input comprising a learning-related data inside a virtual environment of the guide.

A system software and method which relates to the field of computing technology or business process models or computer systems or distributed computer systems or computer networks relating to general purpose devices that can be programmed to carry out a set of data table or hash table updates, validations or modifications supporting, enabling or executing public and private services, financial transactions and commercial applications. More specifically, the present invention is directed to distributed and decentralized computing in which said distributed network is supported and encrypted by cryptographic technology, hash functions and distributed public or private keys or other related technology. System and methods for managing dynamic electronic documents on a private distributed ledger comprise establishing a dynamic electronic document comprising a first state object, wherein the state object references a prior approved first transaction; proposing a second transaction comprising as an input the first state object and as an output a transaction command to alter the state object as well as what parameters are required to validate the second transaction; validating the proposed second transaction; and updating the state object on a private distributed ledger to reference the second transaction.

Disclosed is a system and method for recommending books based on a vocabulary of a user and coordinating books and user vocabulary growth trajectory in such a way that makes it possible for the user to read books of their choice before reaching the vocabulary size sufficient to read, with adequate comprehension, practically any book in general while maintaining a sustainable speed of vocabulary growth. Further disclosed is a vocabulary-based flashcard generator assistant system that allows users to quickly create high-quality flashcards with personalized and optimal content.

An exercise feedback system receives exercise data such as images or video captured by client devices of users performing exercises. The exercise feedback system may access a machine learning model trained using image of a population of users. The images used for training may be labeled, for example, as having proper or improper musculoskeletal form. The exercise feedback system may determine a metrics describing the musculoskeletal form of a user by applying the trained machine learning model to images of the user as input features. The exercise feedback system may generate feedback for a certain exercise using the metrics based on output predictions of the model. The feedback can be provided to a client device of the user or a physical therapist for presentation.
