Design for error recovery to guide users back on track from "summary" of Designing Voice User Interfaces by Cathy Pearl
When designing a voice user interface, it's crucial to consider the possibility of errors occurring during user interactions. Users may make mistakes, misunderstand prompts, or encounter technical issues that lead them off track. To address this, designers should implement strategies for error recovery to guide users back on the right path. One way to design for error recovery is to anticipate common mistakes users might make and provide clear, concise feedback to help them correct their errors. For example, if a user provides an invalid response to a prompt, the system can gently prompt them to try again or offer suggestions for valid inputs. By guiding users in real-time, designers can prevent frustration and confusion, ultimately improving the overall user experience. In addition to providing immediate feedback, designers should also consider the overall flow of the interaction and how users can easily backtrack or start over if they get lost. Offering clear navigation options, such as allowing users to repeat a prompt, go back to a previous step, or start the interaction from the beginning, can help users recover from errors and continue with their tasks seamlessly. Furthermore, designers should strive to make error messages and prompts as natural and conversational as possible. Using a friendly tone, offering helpful suggestions, and avoiding overly technical language can make error recovery feel less like a chore and more like a natural part of the conversation. By maintaining a consistent voice and style throughout the interface, users can feel more comfortable and confident in navigating through potential errors.- Designing for error recovery is about creating a user-friendly experience that empowers users to correct mistakes and stay on track. By anticipating errors, providing clear feedback, offering easy navigation options, and maintaining a conversational tone, designers can guide users back on the right path and ensure a smooth and seamless interaction.
