A method is implemented by a computing device for helping a particular user use a user interface (UI). Electroencephalography (EEG) data is obtained that indicates brain activity of a particular user during a period in which that user views the UI and/or interprets help information that describes how to use the UI. Based on the EEG data, the computing device selects, from among multiple predefined cognitive states, the one or more cognitive states that characterize the particular user during the period. The computing device assists the particular user to use the UI by customizing the help information for the particular user based on the one or more selected cognitive states. A complementary computing device and computer program product are also disclosed.

A real-time virtual reality welding system including a programmable processor-based subsystem, a spatial tracker operatively connected to the programmable processor-based subsystem, at least one mock welding tool capable of being spatially tracked by the spatial tracker, and at least one display device operatively connected to the programmable processor-based subsystem. The system is capable of simulating, in virtual reality space, a weld puddle having real-time molten metal fluidity and heat dissipation characteristics. The system is further capable of importing data into the virtual reality welding system and analyzing the data to characterize a student welder's progress and to provide training.

Methods, apparatus, and processor-readable storage media for artificial intelligence-driven avatar-based personalized learning techniques are provided herein. An example computer-implemented method includes obtaining multiple forms of input data from user devices associated with a user in a virtual learning environment; determining status information for user variables by processing at least a portion of the multiple forms of input data using a first set of artificial intelligence techniques; determining instruction-related modifications for the user by processing, using a second set of artificial intelligence techniques, at least a portion of the multiple forms of input data and at least a portion of the determined status information; implementing, based on the determined instruction-related modifications, modifications to an instructor avatar with respect to the user in the virtual learning environment; and performing one or more automated actions based on user response to the implemented modifications to the instructor avatar.

A method of treatment for intellectual and developmental disabilities is disclosed herein, wherein the method includes the steps of diagnosing an intellectual or developmental disability in an individual, matching symptoms or characteristics associated with the individual's intellectual or developmental disability, researching what personality traits, interpersonal skills, or life skills are affected by the symptoms or characteristics, providing the individual with a list of topics related to the personality traits, interpersonal skills, or life skills are affected by the symptoms or characteristics, selecting a topic related to the personality traits, interpersonal skills, or life skills are affected by the symptoms or characteristics, assisting the individual in preparing a presentation on the selected topic, preparing the presentation, wherein the presentation is between ten minutes and ninety minutes in length, recording the presentation, and broadcasting the presentation.

A method and system for teaching oneself to learn to play a string instrument and master it by analyzing ones real-time hand/finger movement/technique/form, enabling oneself to progress and correct ones own mistakes simultaneously. In one aspect, a system for learning to play a string instrument is provided that includes a simulation instrument that includes a plurality of strings, wherein at least one of the strings includes at least one-touch sensing sensor thereon in communication with at least one processor to receive a signal from the at least one touch-sensing sensor and determine therefrom when and where on the at least one string a user applies pressure to the at least one string.

A learning assistance device for a user to perform a learning task includes: a first concentration level estimator that estimates a first concentration level of the user, by analyzing information from an image capturing section that captures an image of a user; a second concentration level estimator that estimates a second concentration level of the user, by analyzing information which the user has actively input when performing a learning task; and a presentation switching section that switches between learning task content and between presentation schemes, based on at least one of the first concentration level or the second concentration level.

By performing a simple operation on an information processing terminal, a direction of a subject desired to be viewed by a user 40 can be smoothly displayed from various directions. An acquisition unit that acquires a plurality of pieces of moving image data, a data generating unit that generates still image data for each of the plurality of pieces of moving image data, a storage unit that stores the still image data in association with position data and time data, a designated value accepting unit that accepts a position designation value in the still image data desired to be viewed by a user, and a selection unit that selects the still image data on the basis of the position designation value accepted by the designated value accepting unit and transmits the selected still image data to an external display device via a communication network are included, and the selection unit selects the still image data corresponding to the position designation value that has already been designated in a case in which the designated value accepting unit has not accepted the position designation value and selects the corresponding still image data on the basis of a change in the position designation value by using the time data as a reference in a case in which the designated value accepting unit has accepted the position designation value.

A machine-delivered aural cloze exercise makes use of natural, connected speech and allows for a portion of the audio to be selected and obfuscated during playback, creating an aural cloze portion. The aural cloze portion is extended beyond its natural length an effective amount to make the exercise clear to the user. If the audio is accompanied by video, the video is extended uniformly during the aural cloze portion, and optionally, can also be obfuscated during the aural cloze portion.

A portable digital audio system for a musician. The digital audio system includes an amplifier for processing an audio signal from a musical instrument or microphone electronically connected to the digital audio system and a speaker for playing a sound associated with the audio signal processed by the amplifier. The portable digital audio system also includes an audio control system providing operational control of the digital audio system and a primary housing for supporting the amplifier, the audio control system, and the speaker. Further, the digital audio system has a touch screen display in electronic communication with the audio control system and supported by the primary housing.

A scratchpad creation method and an electronic device are disclosed. The method includes: receiving a first input performed by a user on a target identifier, where the target identifier is associated with a first video file; and displaying a first scratchpad in response to the first input, where the first scratchpad is a scratchpad created based on content of the first video file, the first scratchpad includes at least one video identifier and at least one progress identifier, the video identifier is used to indicate a video clip in the first video file, and the progress identifier is used to indicate completion progress of an operation corresponding to the video clip.
