Abstract: The techniques disclosed herein provide systems that can control the invocation of precision input mode. A system can initially utilize a first input device, such as a head-mounted display device monitoring the eye gaze direction of a user to control the location of an input target. When one or more predetermined input gestures are detected, the system can then invoke a precision mode that transitions the control of the input target from the first input device to a second input device. The second device can include another input device utilizing different input modalities, such as a sensor detecting one or more hand gestures of the user. The predetermined input gestures can include a fixation input gesture, voice commands, or other gestures that may include the use of a user's hands or head. By controlling the invocation of precision input mode using specific gestures, a system can mitigate device coordination issues.

Abstract: A system, method, and user interface that allows one to easily navigate a document hierarchy. Document groups are represented graphically with an icon that represents the group type. The icons represent preserved physical attributes of the physical original documents. The icons are dynamically generated based on the preserved physical attribute information. The preserved physical attribute information is initially stored within delimited text values that are stored in a filename but may also be extracted from the filename for storage or use in other data structures. When a document group is selected, the contents (subgroups, documents, etc.) are presented to a user.
