Apple has been working very hard to improve multitouch user experience and hence it’s filing series of patents related to the technology. The latest patent application filed by Apple is called “Swipe Gestures for Touch Screen Keyboard”. In the application Apple showcases various ways swipe gestures can be used to make iPhone’s on screen keyboard faster and easier to use.
Apple says in the patent application, “For example, erasing and basic punctuation insertion, directional swipes (also referred to herein as “swipe gesture”) over the alphabetic keys can be used as an alternative to striking certain keys. Because the Space and Backspace keys are quite frequently used, they are logical candidates for the rightward and leftward swipes, respectively. Leftward and rightward swipes intuitively match the cursor travel caused by these symbols. Following this cursor movement analogy, the Enter / Return may be invoked by a downward swipe, and a Shift/Caps may be invoked by an upward swipe. Alternatively, as the Enter and Shift functions may be less frequently invoked, these may be substituted for other functions as well. One alternative mapping for the upward swipe, for example, could be to activate an alternative numeric and punctuation keypad or a particular punctuation symbol like an apostrophe or period.”
Apple further explains multitouch swipes that use two or three fingers. For example, single finger leftward swipe will delete a letter, whereas a two finger leftward swipe will delete a word and a three finger swipe could be used to delete a complete sentence. Additionally upward and downward swipes could invoke different functions based on the number of fingers used.
By the amount of patent applications Apple has filed for multitouch and the kind of innovations these multitouch technologies can bring, we are very sure that present iPhone’s multitouch interface is just the beginning. We will see some great new features and devices in the very near future.
