Alignment- and orientation-based task assistance in an AR environment
Embodiments described herein provide a system for facilitating dynamic assistance to a user in an augmented reality (AR) environment of an AR device. During operation, the system detects a first element of an object using an object detector, wherein the object is associated with a task and the first element is associated with a step of the task. The system then determines an orientation and an alignment of the first element in the physical world of the user, and an overlay for the first element. The overlay can distinctly highlight one or more regions of the first element and indicate how the first element fits in the object. The system then applies the overlay to the one or more regions of the first element at the determined orientation in the AR environment.

determining an orientation and an alignment of the first element in physical world of the user;
enhancing, within the AR environment, a resolution of an image of the first element;
determining a hologram of the first element and the associated element, wherein the hologram distinctly depicts the first element and the associated element, and wherein the hologram indicates how the first element fits in the object; and
projecting the hologram of the first element and the associated element in the AR environment, wherein the determined orientation triggers the projection of the hologram in the AR environment.

7. The method of claim 1 , further comprising:
determining an overlay for one or more regions of the first element;
determining a first region of the one or more regions of the first element, wherein the first region is attachable to a second region of a second element of the object; and
setting a same mark in the overlay for the first and second regions; and
placing the overlay on the one or more regions by placing the same mark on the first and second regions.
8. The method of claim 1 , further comprising:
determining whether the AR device is capable of determining that the step is complete;
in response to the AR device determining that the step is complete, detecting a third element of the object using the object detector, wherein the third element is associated with a subsequent step of the step; and
in response to the AR device being unable to determine that the step is complete, waiting for an instruction from the user.
9. The method of claim 1 , further comprising:
obtaining a three-dimensional model of the first element;
identifying the one or more regions in the three-dimensional model; and
projecting the hologram based on the identified one or more regions in the three-dimensional model.
10. The method of claim 1 , further comprising determining the step of the task from a task model that includes one or more steps for completing the task, and wherein one or more elements of the object are associated with a respective step of the one or more steps.
11. An apparatus providing dynamic assistance to a user in an augmented reality (AR) environment, comprising:
a processor;
a storage device coupled to the processor and storing instructions that when executed by the processor cause the processor to perform a method, the method comprising:
detecting, by the AR device, a first element of an object and an associated element using an object detector, wherein the object is associated with a task and the first element is associated with a step of the task, and wherein the associated element is external to the object and facilitates attachment of the first element to the object;
determining an orientation and an alignment of the first element in physical world of the user;
enhancing, within the AR environment, a resolution of an image of the first element;
determining a hologram of the first element and the associated element, wherein the hologram distinctly depicts the first element and the associated element, and wherein the hologram indicates how the first element fits in the object; and
projecting the hologram of the first element and the associated element in the AR environment, wherein the determined orientation triggers the projection of the hologram in the AR environment.
