Abstract
Systems and methods for enhancing trackability of a passive stylus. A six degree of freedom (6DoF) location and orientation of a passive stylus may be tracked by a tracking system via a retroreflector system disposed on the passive stylus. Additionally, characteristic movements of one of a user's finger, hand, and/or wrist may be recognized by the tracking system. The passive stylus may useable to interact with a virtual 3D scene being displayed via a 3D display. A user input via the passive stylus may be determined based on the tracked 6DoF location and orientation of the passive stylus and/or the recognized characteristic movements. The retroreflector system may include multiple patterns of retroreflectors and one of the patterns may be a spiral pattern of retroreflectors disposed along a longitudinal axis of the passive stylus.
