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