Abstract: A see-through head mounted display with controllable light blocking includes an optics module comprising a light source and image source positioned on a same side of an angled partially-reflective surface, wherein the light source projects light off the surface to the image source which reflects the light as image light to the surface which transmits the image light along a first axis. The display also includes a flat combiner positioned to reflect the image light off of a first side and simultaneously transmit incident light through the first and a second side, along an optical axis perpendicular to the first axis to provide a view of a displayed image overlaid onto a see-through view of the environment, and a controllable light blocking element arranged generally parallel to the flat combiner and in front of the second side to block light incident on the same optical axis as the image light.

Abstract: Aspects of the present invention relate to methods and devices for receiving and presenting content. In an example method, content is received, the content to be delivered to a plurality of recipients. Each recipient of the plurality of recipients has a preference for a respective first physical location at which the content is to be presented on a display of a wearable head device associated with the recipient. A sender of the content has a preference for a second physical location at which the content is to be presented to the respective recipient of the plurality of recipients. A respective final physical location for the presentation of the content for the respective recipient of the plurality of recipients is identified. The respective final physical location is based on the respective recipient's preference and the sender's preference. It is determined whether the respective recipient is proximate to a zone associated with the respective final physical location.
