Target concept: Infrared thermal imaging camera shows a fading warm handprint on the table.

Video generation prompt: An infrared thermal imaging camera shows a desktop: a bare hand is placed flat on the table for several seconds, then lifted away from the surface.

Evaluation guide:
(i) Target concept: Transient conductive thermal residue from warm object contact on cooler substrate, visualized via infrared thermography.
Minimum mechanism: Skin-to-table conductive heat transfer occurs during contact; table material has finite thermal diffusivity and emissivity; residual surface temperature elevation exceeds ambient long enough to be resolved by IR sensor; thermal camera uses false-color or grayscale mapping where warmer = higher intensity.
(ii)Storyline: Frame 1–3: Hand approaches and settles into full palm-down contact on table; table surface shows uniform thermal baseline. Frame 4–6: Hand remains motionless in contact; no handprint visible (heat conduction ongoing but not yet surface-resolved). Frame 7: Hand begins vertical lift, no handprint yet. Frame 8: Hand fully lifted and clear of surface; table now shows distinct warm handprint in exact spatial correspondence. Frame 9–10: Handprint remains visible, anatomically coherent, and tonally warmer than surrounding table; no fading, distortion, or misalignment.

Experimental Procedure
1. Place bare hand flat and fully palm-down on tabletop for visible stillness.
2. Lift hand vertically and completely off the surface.
3. Maintain fixed thermal camera viewpoint throughout.
Observation of Experimental Phenomena
A warm-toned, anatomically shaped handprint—matching the lifted hand"s orientation and position—appears exclusively on the table surface after lift-off and persists visibly.
Summary of Experimental Principles
Infrared thermal imaging detects surface temperature differences; human skin is warmer than typical indoor tabletops; heat conducts into the table surface on contact and lingers briefly after removal, creating a transient thermal signature visible as a warmer region.

Prompt Grounding rubric:
level_1: No bare hand, no tabletop, and no infrared/thermal camera view are shown, or the scene is unrelated (e.g., a microscope, a liquid experiment, or an outdoor scene) with no hand-table contact event at all.
level_2: A table and a bare hand are both visible, but the hand never presses flat with its whole palm against the table (for example it only hovers, grips something, or moves past the table without settling), or the footage uses an ordinary visible-light camera instead of an infrared thermal view.
level_3: A bare hand and a table are shown from an infrared thermal-camera viewpoint (grayscale or false-color heat-map rendering); the hand presses flat with its whole palm onto the table and holds that contact for a visibly sustained period, then is lifted away from the surface, matching the setup and actions described in the prompt.
level_4: All of score 3 is satisfied, and the thermal-camera viewpoint and framing stay fixed and unchanged from before contact through the full lift-off, with no cuts, repositioning, or reframing; the hand clears the table completely at lift-off rather than only partially rising.
level_5: All of score 4 is satisfied, and the hand's full-palm contact is clearly sustained for several seconds (not a brief tap), the lift-off is a single continuous vertical withdrawal (not repeated taps, wobbling, or partial re-contact), and the table surface beyond the hand's footprint stays fully visible and unobstructed throughout the entire sequence.

Scientific and Causal Correctness rubric:
level_1: No thermal signal of body heat is shown: no lighter/warmer-toned region ever appears on the table, or a handprint-shaped mark appears in a color unrelated to heat (e.g., a red mark on what is clearly a normal daylight video, not a thermal view), or any warm mark cools back to the table's baseline tone within the very next frame after the hand lifts.
level_2: A patch of altered tone appears on the table, but it is a uniform blob with no palm-versus-finger distinction, or its brightness matches the surrounding table (no discernible warmth difference), or it is visible only while the hand still touches the table and vanishes the instant the hand lifts.
level_3: A warmer-toned patch (lighter in grayscale, or a warm hue in false color) appears on the table only after the hand lifts away; its outline loosely resembles a hand, but it lacks real anatomical detail (no separated fingers, no distinguishable thumb, no palm contour), or it fades away within the first frame after appearing.
level_4: The warm patch appears only after lift-off, never while the hand is still touching the table; it shows a recognizable palm shape with separated fingers and a thumb in roughly the correct place; its tone is consistently warmer/lighter than the surrounding table, not cooler/darker; but one flaw remains: either the print is mirrored relative to the hand's true orientation, it visibly overlaps the hand's position during the lift itself, or a faint warm patch is already visible before the hand fully lifts.
level_5: The warm patch appears exclusively after the hand has fully lifted away, never during contact or before, and matches the hand's true orientation (not mirrored); it shows a clearly recognizable palm contour, five separated fingers, and a correctly placed thumb; it is distinctly warmer/lighter than the surrounding table and stays visible for more than a moment after lift-off, with no sudden cooling, tonal inversion, or unexplained warm smearing beyond a natural soft edge.

Spatiotemporal Consistency rubric:
level_1: Severe spatiotemporal rupture: the hand appears to jump to a different position on the table between frames with no continuous motion connecting the two; the table's edge or shape visibly distorts or fractures from one frame to the next; the thermal image's tone mapping abruptly inverts or swaps (warm and cool areas trade places) mid-sequence; the camera view jumps or rotates with no continuous motion.
level_2: Moderate inconsistency: the hand lifts away but the table surface underneath shows no thermal trace at all, even briefly, while the rest of the scene behaves normally; or the table surface appears to stretch or warp exactly where the hand rested; or the overall thermal contrast of the scene flickers unevenly, independent of anything the hand does.
level_3: Minor but noticeable flaws: the hand keeps a fixed size and orientation during contact and lift, the table stays flat and rigid, and the thermal rendering of the background stays even; but small issues remain, such as the warm patch appearing all at once instead of gradually, the lift motion pausing or jerking briefly, or the table's visible edge drifting noticeably (more than about 10% of the frame width) to one side.
level_4: All of score 3 holds, and additionally the hand lifts in one smooth, continuous vertical motion; the warm patch builds up gradually across more than one frame rather than snapping in instantly; the table shows no lasting warping once the hand clears it; the thermal rendering shows no flicker or sudden tone shift; only one small flaw remains, such as a brief unintended camera drift (less than about 5% of the frame) or a slightly uneven fade at the patch's border.
level_5: No spatiotemporal flaws are visible: the hand rises straight up with no sideways drift; the table stays geometrically stable and flat; the thermal tone mapping of the whole scene stays even and steady throughout with no flicker or sudden shift; the warm patch builds up smoothly and continuously over multiple frames with a natural soft-edged fade at its border; all motion is physically plausible and stays locked to a fixed frontal thermal-camera view with no jump cuts, tearing, or seams between frames.
