Some embodiments provide a Touch Enhanced Interface (TEI) that translates data from touch devices into a wide variety of output actions, free from the construct of mapping such touch data to an on-screen pointer or direct screen-mapped coordinates. Based on the touch and hold of one or more fingers, the TEI enables access to different sets of operations. Then based on different taps, holds, directional slides, and directional flicks of one or more fingers, the TEI performs specific operations in an accessed set of operations. Some embodiments provide a TEI viewer that displays symbols that identify the operations that can be performed using the various touches. |

1. A method of adapting user touches on a touch sensitive surface for performing operations on a computing device, the method comprising:
detecting a touch action comprising essentially simultaneous touches of at least a first finger, a second finger, and a third finger, wherein each finger comprises one of the thumb, index, middle, ring, and little fingers, and wherein said essentially simultaneous touches are attributed to said first, second, and third fingers irrespective of the input sequence of said at least three touches; detecting a modification of said touch action comprising removing the touch of at least one finger of the touch action and retaining the touch of at least one finger of the touch action beyond a time threshold; enabling access to a particular set of operations from a plurality of operations in response to detecting said modification, wherein said enabling comprises enabling access to (i) a first set of operations when said modification comprises retaining touch of the first finger and removing touches of the second and third fingers, (ii) a different second set of operations when said modification comprises retaining touch of the second finger and removing touches of the first and third fingers, and (iii) a different third set of operations when said modification comprises retaining touch of the third finger and removing touches of the first and second fingers; and performing an operation from the particular set of operations in response to detecting a reissued touch of the touch action previously removed as part of the modification to said touch action. |
