This visual representation of items is a cornerstone of the feature, making it simple for users to find what they need.

Search Bar Functionality

To enhance item accessibility, a search bar should be included within the fragment layout. This allows users to quickly find specific items by typing in keywords or item names. The search bar should be easily accessible, ideally positioned at the bottom of the screen for convenient thumb access, as indicated in the prototype. Implementing a search suggestion feature can further streamline the search process, providing users with relevant suggestions as they type. The search functionality should be robust and efficient, delivering accurate results even with partial or misspelled search queries. Search results should be displayed clearly and intuitively, allowing users to quickly identify the item they are looking for. The search bar complements the visual browsing experience, catering to users who prefer a more direct approach to finding information. This feature is particularly useful for items that may not be easily categorized or visually identifiable.

Detail Screen for Recyclability Instructions

Tapping on an item thumbnail should open a detail screen that provides comprehensive information about the item's recyclability, compostability, or landfill disposal options. This screen is crucial for delivering the core value of the feature: providing clear and actionable guidance on proper waste disposal. The detail screen should include a high-quality image of the item, a clear indication of its disposal options (e.g., recyclable, compostable, landfill), and any specific instructions or considerations. For example, if an item is recyclable, the screen should specify whether it needs to be cleaned or prepared in a certain way before being placed in the recycling bin. If an item is compostable, the screen should indicate whether it can be placed in a home compost bin or requires industrial composting. For items that belong in the landfill, the screen may provide alternative disposal options, such as donation or repurposing. The detail screen should be designed to be informative and easy to understand, using clear language and visual cues to guide users. This screen serves as the final step in the item identification process, empowering users with the knowledge they need to make responsible disposal decisions.
