Abstract

Offenbart ist ein Verfahren zum Abschätzen einer virtuellen Schreibebene (VSE) bei der Eingabe von Steueranweisungen durch Bewegungen im dreidimensionalen Raum. Zunächst wird ei­ne Bewegung einer Eingabevorrichtung in einem von drei Rich­tungsvektoren aufgespannten dreidimensionalen Raum erfasst, indem zu bestimmten Zeiten Ortspunkte (OP) in dem dreidimen­sionalen Raum ermittelt werden, welche die Kurve (BT') der Bewegung der Eingabevorrichtung repräsentieren. Anschliessend werden die ermittelten Ortspunkte auf eine erste Ebene (XYE), welche von dem ersten und dem zweiten Richtungsvektor gebil­det wird, projiziert, so dass erste projizierte Ortspunkte auf der ersten Ebene erzeugt werden. Ferner werden die ermit­telten Ortspunkte auf eine zweite Ebene (YZE), welche von dem dritten und zweiten Richtungsvektor gebildet wird, proji­ziert, so dass zweite projizierte Ortspunkte auf der zweiten Ebene erzeugt werden. Schliesslich wird eine erste und zweite Regressionsgerade durch die jeweiligen ersten und zweiten projizierten Ortspunkte bestimmt, um einen ersten und zweiten virtuellen Richtungsvektor zum Aufspannen der virtuellen Schreibebene zu erhalten.
