This document defines a set of standard application layer interfaces called JAUS HMI Services. JAUS Services provide the means for software entities in an unmanned system or system of unmanned systems to communicate and coordinate their activities. The HMI Services represent the platform-independent Human Machine Interface (HMI) capabilities commonly found across all domains and types of unmanned systems. Five services are defined in this document: Drawing; Pointing Device; Keyboard; Digital Control; Analog Control

Each service is described by a JAUS Service Definition (JSD) which specifies the message set and protocol required for compliance. Each JSD is fully compliant with the JAUS Service Interface Definition Language (JSIDL) [AS5684].

The purpose of this document is to provide unmanned systems, subsystems, and payloads a standard message set for the definition of HMI drawing functions and associated control mechanisms. While this standard does not mandate a particular application, a common use allow an unmanned system to provide a consistent user interface across a variety of Operator Control Units (OCUs).
