Implementations of various computer methods to couple a computerized ball device which acts as a mobile computing device to record the users environment and project light towards waveguide eyeglasses or contacts which then allows a user to view imbedded light structure holograms in the waveguide while viewing the actual world. The computer ball device additionally has the ability to be docked in a drone cradle which creates a database map of the user's environment while not being utilized by the user for an immediate task. The device may also attach to a wrist band for mobility. The device also has the ability to couple the projected light structures so that a plurality of users may view the same light structure content to build an environment of trust. The device decouples the traditional design of head mounted virtual and mixed reality that place together the camera with the head mounted device.

A smart training accessory connected to musical instrument for aiding users in learning and collaboration is disclosed. The accessory includes a plurality of sensors for collecting data pertaining to the musical instrument. A microcontroller processes the data collected by the plurality of sensors to: (a) determine a type of musical instrument to which the smart training accessory is connected and (b) generate an alert for encouraging an individual to play the musical instrument when the user enters a monitoring area within the vicinity of the smart training accessory. Furthermore, when the user plays the musical instrument, the plurality of sensors captures data including audio recordings and transmits the data to a training and synchronization system. The training and synchronization system processes the received data to generate real-time feedback for the user and further aids collaboration with other users.

The present invention relates to a music chords conversion device. The device is used for providing instant representation showing conversion or correlation of major chords to minor chords and vice versa. The device can come in two variants (1) a physical device (2) a digital device. The physical device has a chords conversion component and a minor chords component wherein the minor chords component is configured to slide into the chords conversion component through a cut-out opening. The minor chords can be correlated to the major chords and displayed in a viewing region of the chords conversion component. The digital device includes a memory for storing the chords conversion and also includes a digital display for displaying the converted minor and major chords.

Provided are a program and a sound output device for maintaining the interest of the user. A sound output device 1 which outputs prescribed musical scales comprises: a level information acquisition unit 13 that acquires, as level information, a user's sense of pitch; a sound output unit 16 that outputs sound of which the pitch has been changed under prescribed conditions based on the acquired level information; a response information acquisition unit 19 that acquires, as response information, a response to the change in a musical scale input by the user on the basis of the output musical scale; a correctness determination unit 20 that determines the correctness of the acquired response information; and a level determination unit 21 that determines the level of the user's sense of pitch on the basis of the determination result.

A computerized educational and entertainment system for one or more users comprising several modules, including a film module and an educational game module, wherein audio-video content of the film module is interrupted by one or more active modes at one or more set times to provide interactive teaching of subject matter.

According to one embodiment, provided is a harmonics learning system comprising: a communication unit for providing, to a user terminal, sheet music of at least one first voice part, and receiving, from the user terminal, sheet music of at least one second voice part that excludes the first voice part; a model generation unit for generating a scoring model by using a plurality of rules divided into vertical elements and horizontal elements; and a control unit for marking harmonic scores with the sheet music of the first voice part and the sheet music of the second voice part by using the scoring model.
