The Continua Design Guidelines (CDG) defines a framework of underlying standards and criteria required to ensure the interoperability of devices and data used for personal connected health. It also contains design guidelines (DGs) that further clarify the underlying standards or specifications by reducing options or by adding a missing feature to improve interoperability. These guidelines focus on the following interfaces:

• Personal Health Devices (PHD) interface - Interface between a Personal Health Device (PHD) and a Personal Health Gateway (PHG).
• Services interface - Interface between a Personal Health Gateway (PHG) and the Health & Fitness Service (HFS).
• Healthcare Information System (HIS) interface - Interface between the HFS and the Healthcare Information System (HIS).
