  • Selection of mathematical objects from the history screen on a handheld device
    Patent number: 6956560
    Abstract: A graphing calculator (10) having a user interface that allows the user to easily select mathematical objects from the history screen and incorporate those objects as inputs. The user interface preferably includes a sub-expression selection mode that allows the user to manipulate a selection box over the desired mathematical object.
    Type: Grant
    Filed: August 24, 2001

  • Subexpression selection of expression represented in contiguous tokenized polish representation
    Patent number: 6874005
    Abstract: An algorithm and handheld device adapted to select a subexpression of a mathematical expression. An expression string of the handheld device is selected, and the expression string is converted to a contiguous tokenized Polish representation (CTPR) of the expression, and the CTPR of the expression is loaded into an n-ary tree. The user may navigate the visual representation of the expression to select a subexpression. The handheld device is adapted to select the subexpression from the n-ary tree.
