Systems with adjustable cushions

Abstract

A head-mounted device may have a head-mounted housing. The head-mounted housing may have rear-facing displays that display images for a user. The images are viewable from eye boxes while the head-mounted device is being worn by the user. An electrically adjustable face cushion may be provided between the head-mounted housing and the user's face. The electrically adjustable face cushion may have adjustable elements such as adjustable inflation air bags. Airflow control systems formed from electrically adjustable airflow valves, check valves, and air pumps may be used in controlling inflation of the adjustable inflation air bags in responses to changes in operating mode of the head-mounted device and/or in response to sensor data or other input. The sensor data may include strain gauge measurements of facial pressure on the air bags.
