Computer Systems With Finger Devices

A head-mounted device operable with a finger device that is configured to gather finger input from a finger of a user, comprising:

• control circuitry configured to receive the finger input from the finger device;
• head-mountable support structures;
• a display supported by the head-mountable support structures;
• and
• a gaze tracker configured to gather point-of-gaze information, wherein the control circuitry is configured to use the display to display virtual content that is overlaid on real-world content and that is based on the point-of-gaze information and the finger input.

A finger device operable with a head-mounted device that is configured to display virtual content over a real-world object, the finger device comprising:

• a housing configured to be coupled to a finger at a tip of the finger while leaving a finger pad at the tip of the finger exposed;
• a haptic output device coupled to the housing;
• sensor circuitry configured to gather finger position information as the finger interacts with the displayed virtual content;
• and
• control circuitry configured to provide haptic output to the finger using the haptic output device based on the finger position information.

A finger device configured to be worn on a finger of a user, comprising:

• a housing configured to be coupled to a tip of the finger while leaving a finger pad at the tip of the finger exposed;
• a haptic output device coupled to the housing;
• a touch sensor configured to gather touch input along an exterior surface of the housing;
• and
• control circuitry configured to provide haptic output to the finger using the haptic output device based on the gathered touch input.

A finger device operable with a wireless electronic device and configured to be worn on a first finger of a user while receiving touch input from a second finger of the user, comprising:

• a housing configured to be coupled to the first finger;
• a touch sensor configured to gather touch input along an exterior surface of the housing from the second finger;
• and
• control circuitry configured to wirelessly transmit the gathered touch input to the wireless electronic device.

A finger device operable with a wireless electronic device and configured to be worn on a first finger of a user while receiving touch input from a second finger of the user, comprising:

• a housing configured to be coupled to the first finger;
• a sensor configured to gather finger input from the second finger within a region on the first finger that is not overlapped by the housing;
• and
• control circuitry configured to wirelessly transmit the gathered finger input to the wireless electronic device.

A finger device operable with a computer having a display, the finger device comprising:

• a housing configured to be worn on a finger of a user;
• a haptic output device;
• a sensor configured to gather user input as the finger of the user touches the display;
• wireless communications circuitry configured to transmit the user input to the computer;
• and
• control circuitry configured to use the haptic output device to provide haptic output to the finger of the user as an exposed surface of the finger touches the display.

An electronic device operable with a finger device that is configured to be worn on a finger of a hand of a user and that has a sensor configured to gather user input, the electronic device comprising:

• a display;
• a hand-tracking system configured to measure movement of the hand of the user;
• wireless communications circuitry configured to receive user input gathered with the sensor in the finger device;
• and
• control circuitry configured to move an object on the display in response to the measured movement of the hand and in response to the user input.
