A wearable apparatus is provided for capturing and processing images from an environment of a user. In one implementation, the wearable apparatus is used for causing a device paired to the wearable apparatus to execute a selected function. The wearable apparatus includes an image capture device, a transmitter and at least one processing device. The at least one processing device is programmed to obtain images captured by the image capture device; analyze the images to detect a contextual situation associated with images; based on the detected contextual situation, associate with the at least one image a category tag, wherein the category tag is associated with a selected function; determine image-related information associated with the detected contextual situation; and cause the transmitter to transmit the determined image-related information to the paired device to cause the paired device to execute the selected function based on the determined image-related information.
