Abstract: A new Computer Mouse Handwriting Transfer Device for capturing human handwriting movements with a computer mouse. The inventive device includes a first plate member moveable in a first direction and blocked from movement in a second direction orthogonal to the first direction. A second plate member rests on the first plate member and is moveable with the first plate member in the first direction and is moveable independently in the second direction. Barrier walls block first and second direction movement of a computer mouse having its sensing ball in contact with the upper surface of the second plate member so that movement of the second plate member is communicated to the sensing ball of the computer mouse. The second plate member has a recess therein for receiving the end of a writing instrument so that handwriting movements of the hand writing tool may be transferred to the sensing ball of the computer device.
