mocopi is a free iPhone application developed by Sony Corporation. It allows users to control avatars and capture motion data using a small and lightweight sensor called mocopi, which is connected to the smartphone via Bluetooth.

With mocopi, users can create avatar videos and acquire motion data directly on their smartphones. The application supports both default materials and external data, giving users the flexibility to customize their avatars.

One of the standout features of mocopi is its ability to acquire motion data outdoors, regardless of the user's location. This means that users can capture realistic motion data even when they are on the move.

mocopi also offers integration with Metaverse services and B14 development software. This allows users to send motion data to a PC in real-time, opening up possibilities for further development and collaboration.
