Assembly or repair tasks often require objects to be rotated or held in specific orientations for inspection or attachment. However, instructing a user to perform such tasks via verbal instructions can be imprecise, and may also involve physical constraints that limit the number of possible orientations. This technology is an augmented reality-based approach for guiding users in performing unconstrained, manual 3D rotation of handheld objects. Using either a head-mounted wearable display or other display configurations, overlaid graphics that move in sync with the handheld physical object provide tracking and instructions on how to orient the object.
This technology uses augmented reality to assist users in identifying and manipulating objects. In the visualization provided via a head-mounted display, cylindrical poles which resemble handles extend from the graphical virtual proxy. By rotating the object, the user places the handles in matching colored rings that represent the targeted final orientation. When the matching handle is in the correct position, the target ring changes color to indicate proper alignment. This technique can also include a trail of arrows to indicate specific instructions for directional rotation and provide further guidance for correct alignment.
A prototype of this technology has been tested and was shown to help users perform rotation tasks significantly faster and was preferred over other guidance techniques.
