Most of the smartphones in the present era provide the ability to touch the screen when making a choice or selecting an option. Gone are the days when phones had only hardware keyboards and we had to use keys to navigate around the choices and options in order to pick one. Present day smartphones have the ability to detect single touch, that is, when you use one finger to touch the screen and select an option or multitouch, that is, using more than one finger to touch the screen.
Windows Phone devices are capable of detecting multitouch as they all have the requirement to support multitouch screens. That means you as a user can use multiple fingers to produce different inputs, particularly input gestures like tapping, flicking, or pinching. For a user, touch gestures are the primary way to interact with a Windows Phone. Tapping on a button or listbox item is one such example of an input gesture on the phone.
