Point-of-view object selection

摘要

Example methods and systems may be implemented by a wearable computer to utilize optical-flow analysis to recognize a predetermined user-action, such as selecting an object. An example method may involve a wearable computing device: (a) receiving video data from a video camera of a wearable computing device: (b) determining optical flow for the video data; (c) determining that an optical-flow differential exists at an area within the optical flow for the video data; and (d) responsive to determining that the optical-flow differential exists at the area: (i) identifying an object that is located at the area where the optical-flow differential exists; (ii) performing a search on the object; and (iii) causing a graphical display to display information that corresponds to results from the search.

主权项

1. A method comprising:
receiving video data; determining optical flow for the video data; determining that an optical-flow differential exists at an area within the optical flow for the video data wherein determining that the optical-flow differential exists comprises:
determining that optical flow within the area is of substantially different magnitude than optical flow outside of the area; anddetermining that at least a portion of the optical flow for the video data has a curvature that is characteristic of a predetermined user-action associated with selection of the object; and responsive to determining that the optical-flow differential exists at the area within the optical flow:
identifying an object that is located at the area where the optical-flow differential exists;performing a search on the object that is located at the area where the optical-flow differential exists; andcausing a graphical display to display information that corresponds to results from the search.
