Abstract:
1. A system that facilitates pixel-accurate targeting with respect to a multi-touch sensitive screen comprising: a multi-touch tracking component that tracks multi-touch input comprising input from at least a primary member and a secondary member and that disambiguates between the input from the primary and secondary members; a cursor control component that concurrently controls cursor movement while adjusting at least one of speed, scale, or position of a cursor according to steering input from the primary member and the at least one of speed, scale, or position input from the secondary member; the system is responsive to positioning the primary member as an anchor location over a portion of content on the multi-touch sensitive screen to be zoomed and the secondary member identifies a corner of the portion of content centered at the primary member's anchor location, whereby the secondary member moves closer or further away from the primary member to reduce or to expand the portion of content on the multi-touch sensitive screen; the system is further responsive to lifting the secondary member from the multi-touch sensitive screen upon which time a cursor interface resets to a default un-zoomed state, upon this reset, the cursor is offset with respect to the primary member and the cursor is placed where the cursor was located in a zoomed state; and an analysis component that analyzes threshold activities of a contact area to distinguish between on or off click states by: the analysis component that automatically calibrates threshold activities of the contact area to determine when a threshold activity has been crossed.
