Example of Annotation for "Capture Task"

Example: In the image below, the collector's hands are approaching an object, indicating the start of an action. Press the Q key at this moment.

When the collector has picked up the strawberry and moved it a short distance, this marks the end of the action. Press the R key.

After pressing the R key, choose to add a label. Since this video shows picking up a strawberry from the desktop, the label is: "pick the strawberry from the desktop".

If the object is not in the queue, you can add it manually in both English and Chinese.

Similarly, placing the strawberry back on the desktop is labeled as "place the strawberry on the desktop".

A complete annotation looks like this:

Basic Data Issues: Incomplete data from cameras, tactile sensors, or motion capture.

Tactile Data Error: Incorrect tactile feedback.
