These methods were evaluated according to the appearance and ease of data entry on a touch screen device.
Appearance of the form
One of the mainóFilling in all the required information in Inline Labelsóre discouraging the useróin order to fill out the forms, is their size – the more pól must be filled in, the less willing we are to come to the task. Depending on whichóhe method you choose to create a form, the same form may seem simpler or more complicated.
The method thatówhich in the most efficient wayób uses the space is Inline Labels. Thanks to placing labels inside pól of the form, the number of elements is limitedów and the form becomes visually simpler. Below are screen shotsóThe Cleartrip, Photobucket and Skype account creation feature, whichóre require entering very similar data:

However, the correct completion and submission of the form depends largely not on the appearance but on the ease of entering data.
Ease of data entry
Forms are much more likely to be completed on devices equipped with a traditional keyboard.

Completion of all required informationól using the touch keyboard (account number, recipient’s name, etc.).) is simply too time consuming. Któw hich method to use to create a form should be the easiest to complete?
The biggest problems users encounter while filling the form with inline labels. The reason for these problemsów is the loss of context when entering data. Many times during my research with users I observed situation when respondents got distracted and did not know what field they were filling. The only solution in such a situation is to delete the enteredów. If the form is designed correctly, after deleting all the signóThe label will reappear as for example in. in the dropbox application.

The problem of context loss does not occur in simple, typical forms, e.g. in the login form, whichótandard, there are two fields: login and password. In this case you can use this method without any worries as e.g. in the application work.pl.

Horizontal positioning of the elementór formóalso has a serious drawback. In vertical position smartphoneóThe space for labels and form fields is very limited. Labels cannot consist of too many charactersów and must be written in a small font. Even then, we are exposed to the situation that the entered data does not fit in the field, which makes it difficult to check the correctness of the entered data. Such problems can be encountered e.g. when registering in the PeoPay application.

This problem does not occur when we hold the smartphone horizontally. The space for the label and the form field is then much larger. In this orientation, however, the on-screen keyboard covers a significant part of the screen, and sometimes, as in the case of Photobucket, it is the only element visible on the screen.

A method thatóThe most effective way of supporting the user in completing the data is vertical arrangement of the elementóform. OpróThe form does not have the disadvantages mentioned above, but it allows to place in the form field a hint on how to format the data entered or other information supporting the user, e.g. balance in the IKO application.

If we want to use inline labels, we can do it in simple login forms, whichóThe key is to avoid forms in which the elements are intuitive and it is difficult to lose the context. You should definitely avoid forms, in which youóhe labels are placed next to the related pól. This is the least efficient way to make a purchaseób element placementóform due to the limited size of mobile devices.
