Two section head mounted display
A system is presented in which a head mounted display is realized in two sections such that a section that comes in contact with the human face may be cleaned and sanitized independently of a section with sensitive electronic and optical components.
1. A head mounted augmented reality display system separable into two sections including:
a first section comprising glasses frames, goggles or other eyewear that hold viewing lenses through which a user can see, the first section including a frame that holds the viewing lenses and a pair of temples arranged to rest on the user's ears; and
a second section comprising head tracking cameras and electronic and optical components for the generation and projection of images away from the head mounted display system, wherein projected images that reflect off of a retroreflective surface located external to the augmented reality display system may be seen by the user after passing through the viewing lenses to form an augmented reality image; and
wherein said first section may be separated from said second section and cleaned and sanitized independently with respect to said second section.
2. The system of claim 1 in which the first section does not include any electronic components.
3. The system of claim 1 having a choice of a plurality of sizes and shapes for said first section so as to facilitate fitting to different size and shape human faces.
4. A method of cleaning and sanitizing a head mounted augmented reality display system comprising:
providing a head mounted augmented reality display system that is separable into two sections including a first section comprising glasses frames, goggles or other eyewear that hold viewing lenses through which a user can see and a pair of temples arranged to rest on the user's ears, and a second section comprising head tracking cameras and electronic and optical components for the generation and projection of images away from the head mounted display system, wherein projected images that reflect off of a retroreflective surface located external to the augmented reality display system may be seen by the user after passing through the viewing lenses to form an augmented reality image; and wherein said first section may be separated from said second section;
disconnecting said first section from said second section;
washing or sanitizing said first section independently from the second section after the first section is disconnected from said second section;
reconnecting said first and second sections after washing or sanitizing said first section.
5. The method of claim 4 wherein first section does not include any electronic components.
