Examples of adjustment mechanisms described herein allow a user to control the tilt of the head-mountable device relative to a head securement element, as well as the tightness of the head securement element. Accordingly, the user can select a fit that distributes forces widely, maximizes comfort, allows the user to enjoy the head-mountable device for longer durations of time.

Abstract: While head-mountable devices can provide immersive experiences, a user wearing a head-mountable device can also benefit from activities that include body motion and promote the user's health. Because such activities may not be intrinsically necessary to the operation of head-mountable devices, it can be beneficial to provide additional or modified operations that allow a user to continue operation of a head-mountable device while performing the desired body motions. The head-mountable device can detect movement and/or stasis of the user and determine whether motion would be recommended. Upon determining that motion, an additional motion, or a different motion would be beneficial, the head-mountable device can provide an output to the user that promote such motions. The output can include a notification to the user and/or a modification of the user interface that encourages the user to move in a particular way.
