Abstract: A virtual reality device can implement varying interactive modes for document viewing and editing by displaying, at an application container level, a current mode view in a view frame of the virtual reality device; and in response to receiving an overview command trigger, determining context, including that the current mode view is at the application container level; expanding to a next level view of, e.g., a task level or an overview level; and displaying, at a next level, the next level view in the view frame of the virtual reality device. The current mode view of the application container level includes a container space of an application and an application container level rule for the container space. Conversely, the virtual reality device can adjust the next level view back to the application container level in response to a focused command trigger and identified region of interest.

Abstract: The principles of the present invention relate to rendering stroke pairs. A graphical object includes at least a first stroke and a second similarly oriented second stroke collectively representing a stroke pair. A calculated distance between the first stroke and the second stroke is constrained (e.g., to a center line between the strokes) to mitigate the possibility of rounding errors causing the represented stroke pair to be inappropriately rendered. After the stroke pair is constrained, controls points of the individual strokes can be adjusted so that the individual strokes are appropriately rendered at their respective constrained locations. The adjusted stroke pair is constrained between external reference points for appropriate rendering relative to other graphical objects. The graphical object, including the adjusted constrained stroke pair, is rendered at an output device.

Abstract: Generating an error from an error metric quantifying differences between reference objects representing characters and representations of the reference objects. One embodiment includes a method which includes accessing a reference object representing a character. One or more reference object characteristics are quantified. The reference object characteristics are related to character structural and color information of at least a portion of the reference object to generate a reference object metric. A representation object of the reference object is accessed. One or more representation object characteristics are quantified to create a representation object metric. The representation object characteristics are related to character structural and color information of a portion of the representation object of the reference object corresponding to the portion of the reference object. An error is calculated based on a difference between the reference object metric and the representation object metric.

Abstract: Selectively applying graphical filtering to characters can include the identification of observer characteristics and characteristics associated with different portions of the character. Corresponding filters can then be identified and selectively applied to the characters and, in some instances, without applying the filter to the entire character.

Abstract: Selectively applying graphical filtering to a portion of an object can include accessing an object to be rendered and identifying at least one characteristic of a portion of the object. A corresponding filter is then selectively applied to the at least one determined characteristic and, in some instances, without applying the filter to at least one other portion of the object.

Abstract: Optimizing objects output to a user. One method includes accessing a reference object of a character representing an idealized output. A different representation of the reference object is accessed. The reference object is compared to the representation of the reference object to generate an error metric. An optimization is applied to the representation of the reference object. The optimization is directed to causing the representation of the reference object to more closely approximate the reference object. Comparing objects and applying optimizations is repeated until an acceptable representation of the reference object is achieved. The acceptable representation of the reference object is displayed.

Abstract: Selectively applying graphical filtering to a portion of an object. One method described herein includes a method including accessing an object to be rendered. At least one characteristic of a portion of the object is determined. A filter is selected that has been pre-specified for the at least one determined characteristic. The filter is applied to the portion of the object, while not applying the filter to at least one other portion of the object.

Abstract: A method and system for matching digital information flow to the human perception system. In various embodiments, multi-monitor (multimon) support is leveraged to take advantage of multiple windowing and window positioning to separate elements of different tasks into information planes (which are based on a concept of “triage and focus”). Triage watches the flow of incoming information and determines the nature of the information. Based on the nature of the information and principles of human perception, Focus (or defocus) displays the information where the information is best viewed.

Abstract: The principles of the present invention relate to iteratively solving constraints in a font-hinting language. A computing system accesses a more complex constraint that can not be natively expressed based on the vocabulary of the font-hinting language, the more complex constraint constraining at least a portion of the outline. The computing system decomposes the more complex constraint into a plurality of simpler constraints that can be natively expressed based on the vocabulary of the font-hinting language. The computer system represents each of the simpler constraints in corresponding font-hinting language instructions that can be iteratively processed to at least approximate a solution to the more complex constraint. The font-hinting language instructions are iteratively processed at the computing system or another computing system to cause a graphical object to comply, within a specific tolerance, with the more complex constraint.
