Abstract: A system uses a barometer to determine both a user interface event and a change in elevation. Portable devices are often limited by space to provide a user with features that make a product useful. The system uses the barometer to measure air pressure within a cavity of a housing of a wearable device. The cavity is enclosed by a cover that appears as a physical button. The cover is attached to the housing by a flexible seal that allows the cover to move in response to changes in air pressure or physical touch. If movement of the cover causes a change in air pressure in the cavity beyond a threshold, the change is interpreted to be a user input event. Otherwise, the change in air pressure is determined to be a change in altitude. Using a barometer to determine user input allows for a compact wearable device.
