Abstract
A touch screen device and method for co-extensively and contrastingly presenting text characters (34) and rendering ink (36) in a common area of a user interface. The text characters (34) and the rendering ink (36) are presented in relative contrast such that coextensive text characters (34) and rendering ink (36) are independently legible.
Claims23
A method for co-extensively presenting text characters and rendering ink in a common area of a user interface of a touch screen device, wherein the rendering ink is electronic ink input to a recognizer, comprising presenting the text characters and the rendering ink in relative contrast such that co-extensive text characters and rendering ink are independently legible.
A touch screen device having a user interface comprising:
- a display unit;
- a touch sensitive surface, overlaid on top of the display unit, for receiving pointer input, wherein newly entered ink corresponding to the pointer input and text characters corresponding to previously recognized ink are co-extensively and contrastingly displayed on the user interface such that co-extensive text characters and newly entered ink are independently legible;
- and
- a computing unit, coupled to the display unit and to the touch sensitive surface, having a touch device driver, an ink renderer, a point collection buffer, a recognizer, a primary display memory and a display driver.
