This document outlines Work Package 1 for the SLOPE project which will take place from January to June 2014. The objectives are to define requirements, analyze the system, identify user needs, review current processes, define necessary data and sensors, and specify the system architecture and interfaces. Task 1.3 focuses on defining the Human Machine Interface (HMI) requirements, especially for on-field devices. It will be led by Graphitech and involve several other partners to mockup interfaces for different scenarios like planning, harvesting, and resource management. The HMI will need to support tasks like 3D forest visualization, machine operation, and an online enterprise resource planning system.
