Abstract: A method comprising entering a passive viewing state of an apparatus, receiving information indicative of a first input, determining a first operation based, at least in part, on a passive viewing state and the first input, performing the first operation, receiving environmental sensor information, determining that the environmental sensor information indicates that the apparatus is actively viewed by a user, entering of an active viewing state of the apparatus based, at least in part, on the determination that the environmental sensor information indicates that the apparatus is actively viewed by the user, receiving information indicative of a second input, the second input being substantially the same as the first input, determining a second operation based, at least in part, on the active viewing state and the second input, the second operation being different from the first operation, and performing the second operation is disclosed.

Abstract: A method comprising determining a first display angle of a display comprised by an apparatus with respect to gravity, determining a first contiguous subset of a sequential arrangement of information based, at least in part, on the first display angle, performing a first operation based, at least in part, on the first contiguous subset, determining a second display angle of the display with respect to gravity, the second display angle being different from the first display angle, determining a second contiguous subset of the sequential arrangement based, at least in part, on the second display angle, and performing a second operation based, at least in part, on the second contiguous subset is disclosed.

Abstract: A method comprising precluding display of information on a head mounted display worn by a user, receiving information indicative of an eye orientation of the user, receiving information indicative of a head orientation of the user, determining that a difference between the eye orientation and a centered eye orientation exceeds a threshold eye orientation difference, determining that a difference between the head orientation and an anatomical position head orientation exceeds a threshold head orientation difference, and causing display of a representation of information on the head mounted display based, at least in part, on the determination that the eye orientation exceeds the threshold eye orientation difference from the centered eye orientation and the determination that the head orientation exceeds the threshold head orientation difference from the anatomical position head orientation is disclosed.

Abstract: A method comprising entering a passive viewing state of an apparatus, determining occurrence of a software event, generating a visual event notification that is indicative of the software event based, at least in part, on the passive viewing state, causing display, on a display, of the visual event notification in conformance with an impaired-viewing display mode based, at least in part, on passive viewing state, receiving environmental sensor information, determining that the environmental sensor information indicates that the apparatus is actively viewed by a user, entering an active viewing state of the apparatus based, at least in part, on the determination that the environmental sensor information indicates that the apparatus is actively viewed by the user, and causing display, on the display, of different visual information in conformance with an unimpaired-viewing display mode based, at least in part, on the active viewing state is disclosed.
