Data Types

All event streams in the LAMP API are catalogued by a timestamp and specific "blueprints" (schema) of what kind of data they hold. For example, a sensor event that occurred 20 minutes ago would carry that instant's timestamp, along with a link to what kind of sensor it was, and that sensor's measurement as a payload of data. The kinds of activities and sensors available are declared below, along with the blueprint you can expect their events' data to follow.

Activity Types

In the case of activities (active data) completed by the participant or patient, the activity declares two types of blueprints: static data, or data that relates to the overall session, and temporal slices, data that provides millisecond precision and carries information about each action or intention the participant or patient might have. Furthermore, activities that can be customized will also have settings blueprints, but these won't actually appear in the event data (and are omitted from the fields listed below).

Sensor Types

Active sensor events are produced on a rolling basis via interactions by a Participant. They are transferred to the Platform Server automatically by using the Activity API written in JavaScript. By “beginning” and “ending” a recording of these interactions, as well as “emitting” temporal data during the interaction, an ActivityEvent can be captured and sent to the Platform Server. A list of existing Sensors is provided below with name and description; a live server instance must be consulted for data schema information (see GET /sensor_spec). Implementations for these hardware sensors are provided in the GitHub repository.

⚠️

On iOS devices, the device motion (accelerometer, gyroscope, gravity) sensor collection frequency is currently limited to 0.002 Hz (approximately every 10 minutes) due to a bug in the mindLAMP 2 app. As the issue is resolved, the expected frequency shall be closer to 1-5Hz (approximately once or more per second). → Please contact us directly with concerns or questions.
