Abstract: An apparatus includes an eye cover adapted to be removably mounted on a head-worn computer with a see-through computer display and a flexible audio headset mounted to the eye cover. The flexible audio headset is mounted to the eye cover with a magnetic connection.

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.
