Question

You get a text. It is a reminder from your dentist’s office that you have an appointment tomorrow. It says to type “1” to confirm or “2” to cancel the appointment. You accidentally type a “3” and nothing happens. How could the input validation be improved?

Answer 1

To improve input validation for a dentist's appointment reminder system, immediate feedback for incorrect entries should be provided, the input field should only accept valid options, and an additional prompt for a valid input should be required if an invalid entry is detected.

Step-by-step explanation:

Input validation is a critical aspect of user interface design that ensures only properly formatted data is entered. To improve the input validation for the dentist's appointment reminder, the system should be designed to recognize invalid entries, such as the accidental "3" typed in this scenario. The following measures could be implemented:

• Provide immediate feedback to the user if an incorrect input is detected, such as a message that says "Invalid option, please type '1' to confirm or '2' to cancel."
• Limit the input field to only accept the valid options '1' and '2'.
• Include an additional prompt asking the user to re-enter their choice if any other input is received.

By enhancing the input validation system, users would have a clearer understanding of the required actions and would be less likely to encounter unresponsive scenarios after providing their response.

Answer 2

Redo the one you want

Step-by-step explanation:

Redo the "1" if you are confirming the appointment

Or "2", if you do not.

Do not fret over this worse, comes to worse call your dentist back and explain you hit the 3 by mistake and then tell them your decision .
