Disclosed herein is a method of providing user-customized learning content in a service server, which includes a) for a specific subject, configuring a problem database including at least one of multiple-choice problems each including at least one example, providing the problem to user devices, and collecting example selection data of users for the problem from the user devices, b) estimating a probability of right answer to the problem for each of the users using the example selection data of each of the users, and assuming that any user selects an example of any problem, calculating, for each problem, a change rate of probabilities of right answer to all problems contained in the problem database for the user, and sorting the problems contained in the problem database in the order of the high change rate to recommend them to the user.

A communications training system is provided having a user interface, a computer-based simulator and a performance measurement database. The user interface is configured to receive a speech communication input from the user based on a training content and the computer-based simulator is configured to transform the speech communication to a text data whereby the text data can be aligned to performance measurement database values to determine a performance measure of the speech communication. The format of the text data and the performance measurement database values enable the speech communication to be aligned with predefined performance measurement database values representing expected speech communications for that training content.

A beauty product device is disclosed which includes a variety of sensors for sensing the way in which a user is operating the device. The sensor data can be processed and compared with pre-stored data representative of a desired style and feedback messages generated and provided back to the user to help them achieve the style they wish to achieve based on the comparison.

Systems and methods for improving behavioral therapies encompassing therapies wherein a perceptual stimulus is administered to a subject or a motor behavior is performed by the subject. Such administration of perceptual stimuli or motor performance is paired with the delivery of vagus nerve stimulation to the subject. The vagus nerve stimulation is timed with the sensory stimulus administration or motor performance in a temporal alignment that maximizes neuroplasticity and performance. Systems for performance of the method and associated software are also disclosed

Disclosed herein are system, method, and computer program product embodiments for providing adaptive learning paths based on specified learning goals and student competency. An embodiment operates by receiving a learning objective associated with a user and retrieving from one or more storage devices a competency profile associated with the user. The competency profiles comprise information representing a current competency of the user regarding concepts associated with the learning objective. Then system then selects, based on a concept dependency graph, an ordered set of learning activities that establish a path between the current proficiency and the learning objective. References to the learning activities are stored in a learning activities table associated with the concepts in the concept dependency graph. The system then sends information related to the learning activities to the user.
