Abstract

Motion and/or rotation of an input mechanism can be tracked and/or analyzed to determine limits on a user'"'"'s range of motion and/or a user'"'"'s range of rotation in three-dimensional space. The user'"'"'s range of motion and/or the user'"'"'s range of rotation in three-dimensional space may be limited by a personal restriction for the user (e.g., a broken arm). The user'"'"'s range of motion and/or the user'"'"'s range of rotation in three-dimensional space may additionally or alternatively be limited by an environmental restriction (e.g., a physical object in a room). Accordingly, the techniques described herein can take steps to accommodate the personal restriction and/or the environmental restriction thereby optimizing user interactions involving the input mechanism and a virtual object.
