Modules

This page gives an overview of the official OpenHPS modules that are available. This list does not contain third party modules that provide nodes or data services.

@openhps/core

The core module offers the processing network model and commonly used nodes for sampling absolute and relative positions. It offers 2D, 3D and geographical positioning through trilateration, triangulation, fingerprinting and velocity processing.

Positioning Algorithms

  • @openhps/imu - Adds IMU processing nodes for fusing IMU sensors.
  • @openhps/fingerprinting - Adds various fingerprinting nodes and services for offline and offline positioning models.
  • @openhps/opencv - Provides linkage with opencv4nodejs and OpenCV.js for computer vision algorithms on the server or browser.

Abstractions

  • @openhps/spaces - Enables the concept of symbolic spaces (e.g. building, room) on top of reference spaces.

Data Services

Communication

  • @openhps/socket - Provides node communication through Socket.IO for remote models.
  • @openhps/rest - Provides node communication through restful endpoints.
  • @openhps/mqtt - MQTT client node communication and standalone MQTT server.

Misc

  • @openhps/sphero - Example implementation for controlling and receiving sensor data from Sphero toys.
  • @openhps/react-native - Provides nodes for retrieving sensor data in react-native.
  • @openhps/csv - Read and write data frames from/to CSV files.
