A device and method are provided for providing feedback based on the state of an object. In one implementation, an apparatus for processing images is provided. The apparatus may include an image sensor configured to capture real time images from an environment of a user and at least one processor device configured to initially process at least one image to determine whether an object is likely to change its state. If a determination is made that the object is unlikely to change its state, the at least one processor device may additionally process the at least one image and provide a first feedback. If a determination is made that the object is likely to change its state, the at least one processor device may continue to capture images of the object and alert the user with a second feedback after a change in the state of the object occurs.
