Domain: Object_Inference / hardware_tools

turn: 1
modality: image
input: Please generate an object designed to: 1. Perform the action of projecting a straight reference line onto a surface; 2. Help the user achieve the purpose of marking long, precise straight lines for construction or carpentry.
output: evaluation_points: 1. The overall form of the object in the image should logically support the action of projecting a straight line (e.g., a long body, a mechanism for line deployment).

2. The object possesses key structures or components necessary for achieving the goal of marking precise lines (e.g., a spool for a chalked string, a housing, a trigger/release mechanism).

3. The overall design of the object conforms to normal logic and appears functional.

turn: 2
modality: image
input: Based on the previous prompt and the image you created, add the following physical constraints to this object: 1. To achieve the above function, it must have the physical property of being rigid and durable; 2. It contains a prominent functional component described as a crank or reel handle for winding the line.
output: evaluation_points: 1. The object's basic functional form remains logically consistent with the Turn 1 prompt requirements for an object that performs the action of 'projecting a straight reference line onto a surface' and helps in 'marking long, precise straight lines for construction or carpentry' (e.g., a long body, a mechanism for line deployment).

2. The object's material or form exhibits the physical property of being rigid and durable (e.g., made of hard plastic or metal).

3. The image clearly shows the functional component (a crank or reel handle) in a reasonable position for winding the line.

turn: 3
modality: image
input: Based on the previous prompts, add usage context information: 1. This object is typically used by a specific user group described as carpenters, masons, or construction workers; 2. It is commonly found in a specific location described as a construction site, workshop, or carpentry shop. Please update the image combining these new prompts.
output: evaluation_points: 1. The object's physical attributes and functional components must remain consistent with the requirements established in Turn 1 and Turn 2. Specifically: its form must support 'projecting a straight reference line'; it must exhibit the property of being 'rigid and durable'; and it must include a prominent 'crank or reel handle' for winding the line.

2. The object's style or background environment fits the specific location of a construction site or workshop (e.g., presence of wood, tools, or a rough surface).

3. The object's appearance (e.g., its size, rugged design, lack of decorative frills) suggests it is adapted to the operating habits of the specific user group described in the Turn 3 prompt: 'carpenters, masons, or construction workers' (practical, sturdy, easy to grip).

turn: 4
modality: text
input: Based on all the previous prompt steps and the final image you generated, please select which of the following items you have generated (output the chosen option directly):
Options:
A. Laser Level
B. Chalk Line Reel (Snap Line)
C. Tape Measure
D. Plumb Bob
E. None of the above.
output: answer: B

turn: 5
modality: text
input: According to the form of the item you drew and your inference about it, please select the option that correctly describes how to use this item?
Options:
A. Hold it against a wall and shine a laser dot to check for level.
B. Pull the chalk-covered string taut between two points, then snap it against a surface to leave a straight line.
C. Extend the metal tape to measure a distance, then read the measurement from the markings.
D. Suspend it from a string to find a vertical reference line.
E. None of the above.
output: answer: B
