UI Guidelines

The virtual keyboard uses technology that is designed to predict words as users type them. Users can tap a suggested word

or press the Space key to choose a word from the list.

Best practices

•

Try to minimize the amount of text that users need to type. Typing on a virtual keyboard can be slower and more

difficult than typing on a physical keyboard. Allow users to choose items from pickers where possible. In addition, try to

store and display information that users enter so that they don't have to enter the same information again and again.

•

If the primary task on a screen is to type text (for example, replying to a message or adding a new contact), then display

the virtual keyboard when the screen opens.

•

If the BlackBerry PlayBook tablet is connected to a physical keyboard, do not open the virtual keyboard automatically

when users need to type text.

•

Suppress word prediction in text fields that will probably include text that is not likely to be in the dictionary (for

example in password, phone number, URL, email, and name fields). When users are typing, they might be annoyed if

the keyboard tries to predict words for these types of fields.

Highlighting text

In some applications, users might want to reuse text, links, or photos. For example, users might want to copy text from an

email, save a link as a bookmark, or send a photo to a friend.

Users can highlight items in a couple of ways:

•

Tap two fingers on the screen simultaneously.

•

Touch and hold one or two fingers on the screen.

If users want to extend the highlighted area, they can drag the handles that appear at the beginning and end of the

highlighted text.
