A virtual reality (VR) headset includes a plurality of marker groups each corresponding to a different location on the VR headset. Each marker group includes one or more passive locators having positions relative to each other. Passive locators included in a marker group are configured to reflect one or more bands of light emitted by a source device. A VR system determines positions of passive locators relative to each other in a marker group and bands of light reflected by the passive locators included in the marker group to determine a location on the VR headset. Based on the location on the VR headset, the VR system determines a position of the VR headset and identifies content to provide to the VR headset.
