Applications such as gesture detection and head tracking can utilize one or more imaging elements on a computing device. While it can be desirable to hide these elements as much as possible so as to have minimal impact on the design or appearance of the device, hiding the elements can cause users to inadvertently cover or block these elements when performing certain actions. When one or more of these elements are determined to be blocked or obscured by a user, the device can provide one or more indicators or cues that can indicate not only that the user is blocking an element, but also indicates the location of the element. The cues can take the form of circles, arcs, arrows, or other elements that can guide the user to the location of an element. Other indicators can be used as well, as may include audio and/or haptic feedback.
