Data Object

Data objects represent the object or person that you are trying to determine a position for. It can also represent any other landmark or sensor that could have an absolute or relative position.

Creating data objects

import { DataObject } from '@openhps/core';
// Create an object with unique identifier 'bsigner'
const myObject = new DataObject("bsigner", "Beat Signer");

A data object can be created using its constructor that takes a unique identifier and an optional display name. More information on its construction can be found in the API documentation here.

Creating a custom data object

Depending on what type of positioning system you are creating, you may find yourself having to add data to data frames or data objects that do not exist yet.

An important design principle in OpenHPS is the serializability of every frame, object and data that is included in those data types. This requires the use of decorators to indicate if data should be serialized.

import {
} from '@openhps/core';
export class QRCode extends DataObject {
public url: string = "";
public imageBase64: string = "";
