... two- dimensional cursor control. Unlike Piccione's 2-D control method, our 2-D control method classifies each individual user response into one of two possible classes (yes or no), with two ... the control is two- dimensional rather than one-dimensional because the direction of each movement can be any one of four choices in two dimensions. This is analogous to the two- dimensional control ... cursor move. This two- dimensional control is distinct from one- dimensional control, wherein the computer restricts the dimension of cursor movement, and the user is free to control only the direction...
