Head mountable display

A head-mountable display device, comprising:

• a housing defining an external surface;
• a frame secured to the housing;
• a dial rotatably secured relative to the housing;
• an environmental sensor secured to the frame;
• an optical module secured to the frame, the optical module comprising:
• a display configured to project light toward an eye of a user donning the head-mountable display device;
• and
• a facial feature sensor disposed adjacent the display;
• and
• a processor electrically coupled to the dial, the environmental sensor, the display, and the facial feature sensor;
• wherein:
• the processor is configured to cause the display to project augmented reality content including an immersion level of virtual content simultaneously imposed over real-world content captured by the environmental sensor;
• and
• a rotation of the dial changes the immersion level of the virtual content based on a first portion of the environment at a first distance and a second portion of the environment at a second distance detected by the environmental sensor.

A wearable display device, comprising:

• a housing defining an external surface;
• a dial rotatable relative to the housing;
• a sensor oriented to detect an environment external to the housing;
• an optical module within the housing, the optical module comprising a display configured to project light toward an eye of a user donning the wearable display device;
• and
• a processor electrically coupled to the dial, the sensor, and the display;
• wherein:
• the processor is configured to:
• determine a first portion of the environment at a first distance and a second portion of the environment at a second distance;
• and
• cause the display to project augmented reality content including a first immersion level of pass-through content captured by the sensor and a second immersion level of virtual content, wherein the pass-through content is positioned related to the virtual content based on the first distance and the second distance;
• and
• a rotation of the dial changes the first immersion level and the second immersion level.
