Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may include an imager, an inertial measurement unit, and a processing system. The imager may be configured to capture an image. The inertial measurement unit may have an output. The processing system may be configured to collect positional information indicating a position of the computing device in response to the output from the inertial measurement unit. Further, the processing system may be configured to determine a selected structure captured in the image. Further, the processing system may be configured to identify information corresponding to the selected structure based on the positional information.
