Gesture-controlled virtual reality systems and methods of controlling the same are disclosed herein. An example apparatus includes an on-body sensor to output first signals associated with at least one of movement of a body part of a user or a position of the body part relative to a virtual object and an off-body sensor to output second signals associated with at least one of the movement or the position relative to the virtual object. The apparatus also includes at least one processor to generate gesture data based on at least one of the first or second signals, generate position data based on at least one of the first or second signals, determine an intended action of the user relative to the virtual object based on the position data and the gesture data, and generate an output of the virtual object in response to the intended action.

An electronic stringed musical instrument is provided which is capable of performing string-pressing detection while maintain a neck strength without lowering reliability. Here, Radio-Frequency Identification (RFID) tags where wiring is not necessary are arranged between frets for each of the first to sixth strings, whereby its neck strength is maintained. When a string comes close to an RFID tag in response to a string-pressing operation, the RFID tag wirelessly transmits first identification information including at least its own fret number (string-pressed point) using electrical power acquired by receiving a radio wave transmitted from the string that functions as an antenna. Then, this information is received and demodulated via the string that functions as an antenna. That is, the string-pressed point is detected by non-contact detection, so that string-pressing detection can be performed without lowering reliability.

The present disclosure relates to an apparatus, system, and method that allow non-musicians to compose and perform a musical composition. Although some existing electronic devices can provide a virtual environment to compose and play musical sound digitally, manipulating such a virtual environment can be difficult and may require specific software expertise, as well as knowledge of music theory. The present disclosure provides a platform that facilitates the creation of a musical composition without such software expertise or knowledge of music theory. The platform models a musical composition as a simultaneous playback of one or more musical contents. The platform allows players to control or modify one or more of the plurality of musical contents to generate or synthesize a musical composition.
