Abstract: The technology causes disappearance of a real object in a field of view of a see-through, mixed reality display device system based on user disappearance criteria. Image data is tracked to the real object in the field of view of the see-through display for implementing an alteration technique on the real object causing its disappearance from the display. A real object may satisfy user disappearance criteria by being associated with subject matter that the user does not wish to see or by not satisfying relevance criteria for a current subject matter of interest to the user. In some embodiments, based on a 3D model of a location of the display device system, an alteration technique may be selected for a real object based on a visibility level associated with the position within the location. Image data for alteration may be prefetched based on a location of the display device system.

Abstract: A user interface includes a virtual object having an appearance in context with a real environment of a user using a see-through, near-eye augmented reality display device system. A virtual type of object and at least one real world object are selected based on compatibility criteria for forming a physical connection like attachment, supporting or integration of the virtual object with the at least one real object. Other appearance characteristics, e.g. color, size or shape, of the virtual object are selected for satisfying compatibility criteria with the selected at least one real object. Additionally, a virtual object type and appearance characteristics of the virtual object may be selected based on a social context of the user, a personal context of the user or both.

Abstract: Techniques are provided for displaying electronic communications using a head mounted display (HMD). Each electronic communication may be displayed to represent a physical object that indentifies it as a specific type or nature of electronic communication. Therefore, the user is able to process the electronic communications more efficiently. In some aspects, computer vision allows a user to interact with the representation of the physical objects. One embodiment includes accessing electronic communications, and determining physical objects that are representative of at least a subset of the electronic communications. A head mounted display (HMD) is instructed how to display a representation of the physical objects in this embodiment.

Abstract: In one method of calibrating an instrument having N ports, where N>=2, cables of a first type are characterized by connecting a first cable between two of the ports; performing an “unknown-thru” full two-port calibration between the two ports; obtaining a S-parameter of the first cable; saving the S-parameter of the first cable; and then repeating the connecting, performing, obtaining and saving for additional cables having the first type. The cables having the first type are then disconnected from one of the two ports and a measurement plane is transferred from the connected end of the cable to the disconnected end of the cable. Cables of a second type are then characterized by connecting a second cable between the second of the two ports and the disconnected end of the first cable; measuring a S-parameter of the second cable; and saving the S-parameter of the second cable.

A second port of the device under test is connected to a first port of a device tester. A third port of the device under test is connected to a second port of a device tester. The device tester performs measurements by the device tester to obtain calibration parameters. In response to commands from the device tester, the calibration module changes termination values at the port of the calibration module. The changing of the termination values is performed without physical disconnection of the port of the calibration module from the first port of the device under test.
