Open Sound Control (OSC)

Open Sound Control is a network protocol for sending structured, real-time control messages between computers, microcontrollers, and audio/visual software. It is widely used in interactive systems because it is lightweight, human-readable, and extensible (Wright & Freed, 1997).

1. Message anatomy

An OSC message typically contains:

• Port: UDP port on the receiver.
• Address: a path-like string (e.g., /pose/x).
• Arguments: typed values (e.g., numbers, strings, arrays).

Example address patterns:

• /pose/x
• /hand/left/index_tip
• /sensor/distance
