A system to teach mathematics using virtual musical instruments displayed on a client computing device includes a server, a database stored on the server, an application stored on the server, and a plurality of songs stored on the server. The system also includes a plurality of mathematical equations stored in the database, where each mathematical equation comprises a composite of musical notes and mathematical operators. The system includes a local application stored on the client computing device to display the virtual musical instrument and is configured to display a correct indicator in response to the user solving the mathematical equation correctly when the user plays a musical note on the virtual musical instrument corresponding to the numerical answer that correlates to the song.

Disclosed herein are systems and methods for for dynamically editing online interactive elements to facilitate logical and stepwise execution of a process with an architecture comprising a first centralized data structure comprising a process map, the process map comprising a plurality of nodes, each node representing at least one step of the process, wherein the nodes are arranged in the process map hierarchically and so as to represent relationships between the steps of the process; a library of online interactive elements, each online interactive element comprising dynamically editable content, feedback, and scaffolding; a second centralized data structure comprising a prerequisite map associating each node of the process map with one or more of the online interactive elements; a user interaction record; and an editing engine comprising a selection module, a content editing module, a feedback editing module, and a scaffold editing module.

An information processing apparatus detachable from a human body includes a control unit that generates feedback information that provides feedback in accordance with information based on strength/weakness of a keystroke of a musical instrument.

Methods and systems for assisting tonally-challenged singers. A microphone can be integrated with a sound reinforcement system used in a live performance. The microphone, which can transduce the performer's voice, can serve multiple purposes such as, for example, to feed input to the natural ear and to the sound reinforcement system. The processed sound of the performer's voice (with fundamental frequencies emphasized) can be mixed into the signal fed to a stage “monitor” speaker facing the performer or a headset worn by the performer.

A children's toy with capacitive touch interactivity. The children's toy generally includes a user input overlay panel and one or more capacitive touch sensors. The overlay panel may be formed from a capacitive touch conductive natural organic material such as wood. The toy can be shaped and ornamented to resemble a musical instrument, and configured to play music in response to user input applied to the user input overlay panel and sensed by the capacitive touch sensors.

Described herein are to frameworks and methodologies configured to enable real-time adaptive delivery of skills training data based on monitoring of user performance data. Embodiments of the invention have been particularly to enable real-time control over a performance instruction user interface (for example in terms of rate), and/or control over delivery of media data (for example in terms of rate and/or pan/zoom position).
