User interface interaction elements with associated degrees of freedom of motion
A method may comprise displaying an interaction panel on a display device. The interaction panel having a display frame of reference and include a plurality of interaction elements. The method may also comprise constraining motion of an operator interface device to translational motion in a haptic plane with a haptic plane constraint while the interaction panel is displayed and determining a cursor position in the display frame of reference that corresponds to a position of a selection portion of the operator interface device in an operator frame of reference. The method may also comprise determining an element type for a first interaction element of the plurality of interaction elements at which the cursor position is located and removing the haptic plane constraint on the operator interface device if the element type is a three-dimensional rotation type.
