Abstract
A finger device may be worn on a user's finger and may serve as a controller for a head-mounted device or other electronic device. The finger device may have a housing having an upper housing portion that extends across a top of the finger and first and second side housing portions that extend down respective first and second sides of the finger. Displacement sensors in the side housing portions may measure movements of the sides of the finger as the finger contacts an external surface. To account for variations in skin compliance, the finger device and/or the electronic device may store calibration data that maps displacement values gathered by the displacement sensors to force values. The calibration data may be based on calibration measurements gathered while the user's finger wearing the finger device contacts a force sensor in an external electronic device.
