This section provides touch UI considerations for the Series 40 Touch and Type platform. For detailed implementation guidelines, see Java Developer's Library.

The new features of the Series 40 Touch and Type platform include the following:

• The navigation key and physical softkeys have been removed, and there is a softkey area at the bottom of the screen.
• Devices have a resistive screen with a minimum size of 2.4”.
• The user experience follows single tap interaction: a single tap on any object will select and activate the command.
• Basic touch strokes and gestures are aligned across Nokia devices: content follows finger movement when dragging or flicking.
• Most elements on the screen are touchable. The status area and the scroll bar are only informative, not touchable. In full canvas the full screen is touchable.
• Design is optimised for use with one hand.
• Inputting numbers and text is easy via keypad.
