| Product discovery | Searchable catalogs, product filters, and category navigation | Customers can browse relevant options without having to review every item or wait for assistance. | Searches, filter use, product-detail views, and exits from the catalog | Use clear category names and keep the path back to the main menu easy to find. |
| Self-service information | Interactive FAQs, service directories, and step-by-step guides | Customers can find answers and instructions independently, which can reduce avoidable questions for staff. | Guide starts and completions, topic selections, and requests for staff assistance | Keep information current and provide an obvious route to human help when needed. |
| Personalized exploration | Choice-based recommendations, comparison tools, and preference selectors | Customers can narrow options according to their stated needs and compare relevant details. | Comparison-tool use, selected preferences, and interactions with recommended items | Explain how selections are used and avoid collecting personal information that is not needed. |
| Wayfinding | Interactive maps, location search, and route guidance | Customers can locate destinations and view directions that match their selected destination. | Destination searches, route requests, and repeated searches for the same location | Keep maps and location details aligned with the current layout of the space. |
| Transactions and check-in | Appointment check-in, queue registration, and guided ordering workflows | Customers can enter required details and complete supported steps directly at the screen. | Workflow starts, successful completions, abandoned sessions, and requests for assistance | Show progress, confirm completed actions, and offer a clear alternative if the screen is unavailable. |
| Customer feedback | Short surveys, rating prompts, and structured feedback forms | Customers have a convenient way to share feedback close to the service experience. | Survey starts, submissions, skipped questions, and response themes | Keep questions concise, make participation optional, and explain how feedback will be used. |
| Accessibility and ease of use | Readable text, clear instructions, accessible controls, and alternative ways to complete tasks | More customers can understand the interface and use its core functions, including people with different access needs. | Task completion, errors, time to complete tasks, and accessibility testing feedback | Test with diverse users and provide non-screen alternatives where touch interaction is unsuitable. |
