Abstract: The invention provides a new software tool for editing standard operating procedures (SOPs). Using an augmented reality (AR) device as a carrier, it integrates resources such as 3D models, voice prompts, videos, photo comparisons, prompt boxes and text descriptions. It also introduces artificial intelligence (AI) with 3D spatial position navigation mechanism and simulation operations reality. Accordingly, it makes editing of SOP easier to use and more intuitive.

Abstract: A positioning method is provided for an electrical device including a depth sensor and an inertial measurement unit (IMU). The positioning method includes: calculating an initial position and an initial direction of the electrical device according to signals of the IMU; obtaining an environment point cloud from a database, and obtaining a partial environment point cloud according to the initial position and the initial direction; obtaining a read point cloud by the depth sensor; and matching the read point cloud and the partial environment point cloud to calculate an updated position and an updated direction of the electrical device.
