Self-contained mixed reality head mounted display

A head mounted display system comprising:

• a head mounted display having:
• a main body;
• a sensor;
• a door for accessing a receptacle that is configured to receive a computing device therein, wherein the door is operably connected to the main body via a L-shape hinge mount, wherein the computing device comprises a camera and a display interface and the L-shaped hinge bracket integrally connected to the sensor mount;
• a sensor mount for releasably coupling the main body to the sensor, the sensor mount positioned over the door and configured to move in conjunction with a movement of the door;
• a wide angle lens coupled to an exterior surface of the door by the L-shaped hinge bracket, a center of the wide angle lens configured to align in the x, y, and z position of a center of the camera of the computing device and in the x position with the center of the sensor when the computing device is within the receptacle;
• an adjustment mechanism positioned at a rearward section of the head mounted display opposite the main body, the adjustment mechanism including:
• a back pad foam having a first surface to contact a head of the user during use and a second surface opposite the first surface;
• a back pad insert having a first surface in contact with the second surface of the back pad foam and a second surface;
• a back pad body having a first surface in contract with the second surface of the back pad foam and a second surface, the back pad body coupled to at least one of the two or more semi-rigid securing straps;
• a ratchet gear coupled to the back pad body, the ratchet gear comprising a single locking arm that operably engages a left side strap and a right side strap of the one or more semi-rigid securing straps via a tooth profile to tighten or loosen the first of the head mounted display to the head;
• a counter weight rigidly coupled to the back pad body and positioned at a rearward section of the head mounted display opposite the main body, the counter weight to counter balance a weight of at least a portion of the main body of the head mounted display and the computing device;
• an adjustment device coupled to the counter weight opposite the back pad body and operable by the user to control the ratchet gear.

A head mounted display comprising:

• a main body;
• a door coupled to the main body, the door including a first portion formed from polycarbonate and a second portion formed from metal, the door including at least one magnet to enhance alignment when closed;
• a sensor mount for releasably coupling the main body to a depth sensor, the sensor mount positioned over and movably coupled to the door;
• a receptacle accessible via the door, the receptacle for receiving a computing device, the door configured to close and lock the computing device in a rigid position within the receptacle, the rigid position causing a fixed displacement between the sensor and a camera of the computing device;
• an L-shape hinge bracket to couple the second portion of the door, the L-shaped hinge bracket integrally connected to the sensor mount;
• a wide vision lens coupled to a front surface of the door by the L-shaped hinge bracket and wherein a center of the camera of the computing device is aligned in the x, y, and z position with a center of the wide vision lens and a center of the depth sensor is aligned in the x position with the center of the wide vision lens when the computing device is in the rigid position within the receptacle are rigidly positioned for alignment with a wide vision lens;
• a cable movably coupled to the door and the depth sensor such that the cable, the door, and the depth sensor move together when the door is opened by the user with respect to the main body, the cable to communicatively couple the depth sensor to the computing device;
• a mask positioned between the main body and the head of a user, the mask including at least one modular lens;
• a face foam positioned between the mask and the head of the user;
• two or more semi-rigid securing straps that are configured to secure the main body of the head mounted display to the head of the user, the two or more semi-rigid securing straps having a height and a width dimension, the height being greater than the width to limit a flex or deformation along the height to thereby transfer a distribute a weight of the head mounted display along a front to a back of the head mounted display, each strap including a first portion and a second portion, the second portion haying increased rigidity with respect to the first portion;
• a plurality of haptic exciters positioned along the main body portion and along one or more securing straps;
• an adjustment mechanism positioned at a rearward section of the head mounted display opposite the main body, the adjustment mechanism to adjust a fit of the head mounted display to a head of a user, the adjustment mechanism including:
• a back pad foam haying a first surface to contact the head of the user during use and a second surface opposite the first surface;
• a back pad insert haying a first surface in contact with the second surface of the back pad foam and a second surface;
• a back pad body haying a first surface in contract with the second surface of the back pad foam and a second surface, the back pad body coupled to at least one of the two or more semi-rigid securing straps;
• a ratchet gear haying two hooks to coupled to the back pad body to the ratchet gear, the ratchet gear comprising a single locking arm that operably engages a left side strap and a right side strap of the one or more semi-rigid securing straps via a tooth profile to tighten or loosen the first of the head mounted display to the head;
• a counter weight rigidly coupled to the back pad body and positioned at a rearward section of the head mounted display opposite the main body, the counter weight to counter balance a weight of at least the main body of the head mounted display and the computing device;
• an adjustment device coupled to the counter weight opposite the back pad body and operable by the user to control the ratchet gear;
• and
• an embedded power supply having a battery that is not tethered to an external or fixed power source, the embedded power supply positioned over the weighted component.
