(translation) reasons why real-time inline verification is easier for users to make mistakes

   Using inline validation in the form will reduce the user's filling speed . Inline validation is the display of an error message inline with the error field . Trigger inline validation before the user submits the form , It will make them make more mistakes , And take longer to complete the form .

Verify the fields before submitting the form

   Two studies , One item has 77 participant , Another item is 90 participant , Come to the conclusion , When filling out the form , If the error field loses focus, an error prompt message is displayed , Users will make more mistakes .

   Even if the user has the opportunity to correct input errors immediately , They also ignore error messages . The user continues to fill out the form , And see more error messages when submitting the form . In the study , The error message that appears before the form is submitted will frustrate the user .
   This discovery proves , Field validation before submitting the form will make users make more mistakes , And then increase users' frustration . It is best to reduce the error rate of the form , Let users fill out the form quickly . The slower the form is filled out , The more frustrated the user is , This may cause them to abandon the form .

Field validation after submitting the form

   by comparison , The study found that , After the user clicks the submit button, the error message will be displayed , They make far fewer mistakes .

   This finding can be explained by different input patterns in the process of completing the form . When the user opens the form, it will enter the completion mode , At this point they focus on filling out all the fields , It will not consider whether the input content is correct . After filling in all the fields , The user switches to revision mode , Then focus on correcting mistakes .
   Inline authentication forces users to frequently switch between completion mode and revision mode , Distract and interrupt their attention , This will increase the cognitive load of users , Cause more mistakes , And extend the completion time of the form .
   Users prefer to execute one mode at a time , This will complete the form faster . Executing the completion mode and the revision mode at the same time will affect the user's attention , When all their attention is focused on completion mode or revision mode , You can focus more on implementing this model .

Change blindness

   Field verification before submitting the form will cause change blindness . The error message is ignored when the user is in completion mode , When they do this and click the submit button , Any error messages that appear may be missed . When the form is already full of error messages , It is difficult for users to detect visual changes in the form .
   Field verification after submitting the form can prevent change blindness . Click Submit button , The user sees that the form changes from no error message to error message , Visual changes are very significant , This indicates that the system has verified their submission .

Exception field

   Inline validation after submitting the form does not apply to all fields . The user name field and password field need to be verified before submitting the form , These two types of fields have strict input requirements , If the form is submitted and then verified , The user has to submit multiple times to meet the input requirements .

   Users often choose the user name that other users have registered , It may take multiple entries to find an available user name .
   To be on the safe side , Password fields have multiple content rule restrictions , Multiple entries are required to meet all rule requirements .
   Inline validation before submitting the form is not only applicable to the user name field and password field , It also applies to fields with strict input restrictions .

The user submits the form and then validates the fields

   Field validation after submitting the form can shorten the form completion time , Reduce input errors , Reduce user frustration . Designers want to improve the form filling experience , Please do not validate fields before the user submits the form .
   The field verification after submitting the form matches the mental model of the user filling in the form . Users want to fill out forms as quickly as possible , How fast can the form support , They'll fill it out quickly . Ensure that field validation occurs when the user is in revision mode , Otherwise, it will slow down the user's filling in the form .
