Domain: Object_Inference / recreation_and_instruments

turn: 1
modality: image
input: Generate an object that looks very similar to a violin, but: 1. Unlike a violin, it does not have a chinrest; 2. Instead, it has two strings that run over a small, curved bridge.
output: evaluation_points: 1. The object's overall silhouette is indeed easily confused with a violin.

2. The image clearly does NOT contain a chinrest (a typical violin feature).

3. The image clearly DOES contain two strings running over a small, curved bridge (a distinctive feature of the target object).

turn: 2
modality: image
input: Based on the previous context, further distinguish this object through its physical attributes: 1. It has a uniquely slender and elongated neck; 2. It is typically made of wood with a snakeskin-covered resonator.
output: evaluation_points: 1. Maintains the previously established distinguishing features (has two strings over a small, curved bridge, lacks a chinrest).

2. The object's neck proportions are slender and elongated as described.

3. The object's material rendering is correct, appearing to be made of wood with a snakeskin texture on the resonator.

turn: 3
modality: image
input: Based on the previous context, add this object's exclusive scenario feature: This object is specifically used for playing traditional Chinese music, a scenario in which a guitar is not suitable.
output: evaluation_points: 1. Maintains all physical features from previous descriptions (two strings over a small, curved bridge, no chinrest, slender and elongated neck, wood body with snakeskin-covered resonator).

2. The background or the object's state suggests a traditional Chinese music setting (e.g., a silk banner, a traditional stage).

3. The overall visual effect clearly points to the target object, eliminating the possibility of it being a guitar.

turn: 4
modality: text
input: Based on all the previous prompt steps and the final image you generated, please select which object you have generated (output the chosen option directly):
Options:
A. Violin
B. Cello
C. Erhu
D. Viola
E. None of the above.
output: answer: C

turn: 5
modality: image
input: Based on the previous prompts and the image you generated, now modify this object into an electric erhu. Please keep its appearance features (such as color, patterns) unchanged while updating the necessary components to match the characteristics of this variant.
output: evaluation_points: 1. The item's color and patterns remain largely consistent with the Turn 3 output image (the original erhu).

2. The core features of the erhu (two strings over a small, curved bridge, no chinrest, slender and elongated neck, bow) are retained.

3. The image adds or modifies key structural components to fit the 'electric' variant (e.g., a pickup device, output jack, solid body or electronic resonator).

turn: 6
modality: text
input: Comparing the variant version you drew to the original object, what is the biggest physical structural change made to achieve the variant's function?
Options:
A. The shape of the resonator body
B. The material of the strings
C. The addition of electronic pickups and output jacks
D. The length of the neck
E. None of the above.
output: answer: C
