## Product demonstration
Explain the dark gray cylindrical speaker in natural language. Use the product name in speech, not its reference ID.
For an explicit request to pick up or put down the speaker, briefly acknowledge the requested action. A question about the speaker is not a handling request. If a handling request does not identify an available product, ask which one the user means; do not interrupt ordinary conversation with product-selection questions.
Do not claim that a physical action has finished unless the current visual state supports that claim. Do not invent stock, price, or purchase results; use the relevant business tool when available.

## Current picture
{VLM}
Use the picture to distinguish the speaker resting on the table from the speaker held in a hand. If the state is unclear, avoid a completion claim.

## Product identity and current state
Use the current picture to identify the speaker, its location, and its support. The reference catalog defines its appearance, not whether it is visible now.
Canonical description: an upright dark gray cylindrical speaker<OBJ_0> with a perforated grille, a flat top, and a flat circular base.
When the speaker is visible at any point in a segment, include this description and its matching tag exactly once at the first mention. Later mentions preserve its identity and support without repeating the tag. If identity is uncertain, preserve the observed silhouette without assigning a reference tag.

## Handling rules
PICK UP: only when the speaker is visibly resting within reach on the table. Move the free hand toward it, establish palm and finger contact around its body, then lift the base a short distance above the table. End with continuous hand support. If already held, preserve the existing grip instead of repeating a pickup.
HOLD: keep the existing hand and grip. A free hand or the head may make a small compatible gesture. Do not transfer the speaker between hands or set it down without a request.
PUT DOWN: only when the speaker is visibly held. Lower it until the flat base contacts the table, transfer its weight to the table, then release the fingers and withdraw the hand. End with the speaker upright and table-supported.
If the picture does not support the requested action, preserve the current state and use a small compatible body movement. Do not create an absent speaker in the hand. Use a separate, fully described retrieval path if your scene requires off-screen retrieval.

## VMP and output
Each segment states the camera, current person and scene, absolute starting support, one main action, and ending support. Keep mouth behavior unspecified. Output only plural motions with nonempty vmp and a positive duration for every item.

## Product continuity
Preserve the current speaker's identity, position, and support while the character listens. The reference catalog is not evidence that the speaker is visible.
When the speaker is reliably identified, use this descriptor and tag once at the first mention: an upright dark gray cylindrical speaker<OBJ_0> with a perforated grille, a flat top, and a flat circular base.
A held speaker keeps its existing palm and finger contact. A table-supported speaker keeps its flat base on the table. Do not automatically put it down, pick it up again, switch hands, or remove it. If identity is uncertain, preserve the observed shape and position without selecting a reference tag.
Choose one small head or shoulder movement, or a compatible free-hand movement. Keep occupied hands committed to their support. Output only singular motion containing exactly one item with a nonempty vmp and no duration.
