The head-mounted display includes a combiner configured to combine display light for forming a display image with outside light from in front of a user wearing a head-mounted display, and a light reducing unit configured to transmit a part of outside light from below the combiner and have transmittance equal to or lower than transmittance of the combiner. | 2021-10-14 |
20210318544 | MODULAR SYSTEMS FOR HEAD-WORN COMPUTERS - Aspects of the present disclosure relate to modular expansion systems for use in head-worn computing systems. In an head-worn computer, an electrical connector is adapted to electrically connect with a modular expansion module, wherein the modular expansion module adds a capability to the head-worn computer and is removeably mounted to the head-worn computer, and a mount is adapted to physically secure the modular expansion module to the head-worn computer | 2021-10-14 |
20210318545 | HEAD-MOUNTED DISPLAY - The head mounted display includes: a headgear having an attachment that comes into close contact with the face of the user in a manner such that the user can see at least the front and a fixture that is attached to the attachment and is used for fixing the attachment to the head of the user while maintaining the close contact with the face of the user; a display unit that has a video display unit configured to display video and is detachable from the attachment; and a lock mechanism that is provided in at least one of the attachment or the display unit, and fixes the display unit to the attachment in a manner such that the fixing can be released. The attachment and the display unit are configured to engage with each other in the front-rear direction of the user. | 2021-10-14 |
20210318546 | CONTENT PRESENTATION IN HEAD WORN COMPUTING - Aspects of the present disclosure relate to methods and systems for presenting digital content in a field of a view of a head-worn computer. | 2021-10-14 |
20210318547 | AUGMENTED REALITY VIEWER WITH AUTOMATED SURFACE SELECTION PLACEMENT AND CONTENT ORIENTATION PLACEMENT - An augmented reality viewer is described. A user orientation determination module determines a user orientation. A content vector calculator calculates a content orientation vector relative to a near edge and a far edge of content, determines a dot product of the user orientation vector and the content orientation vector, and positions the content based on a magnitude of the dot product. A surface area vector calculator calculates a surface area orientation vector for each of a plurality of surface area. A surface selection module determines a dot product of the user orientation vector and each surface area orientation vector and selects a preferred surface based on the relative magnitude of the dot products. | 2021-10-14 |
