Text Overlays

The RedisTextOverlayManager allows adding text overlays for video recordings or user interfaces.

Publishing Messages

User Tasks

from redis_robot_comm import RedisTextOverlayManager

text_mgr = RedisTextOverlayManager()
text_mgr.publish_user_task("Pick up the red cube.")

Robot Speech

text_mgr.publish_robot_speech("I am moving to the cube now.", duration_seconds=3.0)

System Messages

text_mgr.publish_system_message("Recording started", duration_seconds=2.0)

Subscribing to Overlays

This is typically used by a recording script:

def display_text(data):
    print(f"[{data['type']}] {data['text']}")

text_mgr.subscribe_to_texts(display_text)
