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 possess the physical property of being durable and water-resistant; 2. It contains a prominent functional component described as adjustable shoulder straps and a padded back panel.
output: evaluation_points: 1. The basic functional form of the object remains logically consistent with the Turn 1 requirement for an object designed for 'carrying personal belongings on one's back' and 'transporting items conveniently during travel or hiking'.

2. The material or form of the object demonstrates the property of being durable and water-resistant (e.g., texture, material indication).

3. The image clearly shows adjustable shoulder straps and a padded back panel in a reasonable position.

turn: 3
modality: image
input: Based on the previous prompts, add usage context information: 1. This object is typically used by hikers, travelers, or students; 2. It is commonly found in outdoor environments, on trails, at campsites, or in urban commuting settings. Please update the image combining these new hints.
output: evaluation_points: 1. The physical properties of 'durable and water-resistant' (from Turn 2 prompt) and the functional components of 'adjustable shoulder straps and a padded back panel' (from Turn 2 prompt) remain unchanged.

2. The style or background environment of the object fits the described specific places from the Turn 3 prompt: 'outdoor environments, on trails, at campsites, or in urban commuting settings'.

3. The object's appearance (e.g., patterns, colors, decorations, or size proportions) suggests adaptation to the operating habits of the user group described in the Turn 3 prompt: 'hikers, travelers, or students'.
