Relative Touch User Interface Enhancements

A method comprising:

• adjusting a position of a pointer in a graphical user interface (“GUI”) based on user input to a first input device, wherein the GUI comprises a plurality of user interface (“UI”) elements;
• invoking a mouse left-click operation on a particular GUI element, that is located at the position of the pointer after said adjusting, in response to a manipulation of a first key on a second input device, wherein the second input device is different than the first input device;
• and
• invoking a different mouse right-click operation on the particular GUI element, that is located at the position of the pointer after said adjusting, in response to a manipulation of a different second key on the second input device.

A method of interfacing with a computer based on one or more fingers of a user hand coming in contact with at least one touch sensitive surface, the method comprising:

• detecting holding touches based on one or more fingers being applied essentially simultaneously on the at least one touch sensitive surface, wherein the one or more fingers remain within a threshold distance of an initial position that is detected for each touch of the holding touches, and the one or more fingers are retained on the touch sensitive surface beyond a specific hold duration;
• performing a touch-to-finger assignment based on two or more of (i) a number of distinct touches within the holding touches, (ii) offset positioning and spacing between the holding touches, (iii) a shape of each touch of the holding touches, (iv) differences between the holding touches and a previous set of applied touches, and (v) a previous left-right hand determination;
• enabling access to a set of output actions based on the touch-to-finger assignment and the continued retention of the one or more fingers on the at least one touch sensitive surface;
• detecting a subsequent tap on the at least one touch sensitive surface;
• assigning the subsequent tap to a particular finger based on two or more of (i) a number of distinct touches within the holding touches plus the subsequent tap, (ii) offset positioning and spacing between the holding touches in combination with the subsequent tap, (iii) a shape of each touch of the holding touches and the subsequent tap, (iv) differences between the holding touches with the subsequent tap and the previous set of applied touches, and (v) the previous left-right hand determination;
• and
• executing a first output action from the set of output actions based on the subsequent tap being assigned to one of a thumb, an index finger, a middle finger, a ring finger, or a little finger, and the continued retention of the one or more fingers on the at least one touch sensitive surface.
