Touch in the Windows Phone 8 application

Windows Phone users have no hardware such as a keyboard and everything is done by touching a screen. We need to ensure that the user will feel good using our application; he or she needs to be able to complete the core actions by using touch. Let them manipulate the content of our application; it should be easier than commands.

Touch and gestures

For sure, our users will appreciate the better user experience. Here are some common touch events that an application usually handles in its controls as follows:

  • Tap on item: It causes invoking of primary actions such as going to a full-size image or message details

  • Press-and-hold on item: It shows a context menu or tooltip (if such is defined)

  • Slide: It is used for moving items, switching radio buttons, or moving between items in Pivot or Panorama

  • Swipe for application commands: It shows an application bar that contains commands depending on the context
