Abstract: In a multi-user, collaborative environment, an operating system state change can occur by passing a stylus pen from one user to another. Upon detecting a change of the active user, a state machine transition can result in a change in a user experience. In one example, a change in the user experience includes a change in user interface (UI) functionality. Some examples include changing color of the digital ink being displayed, changing a handwriting pattern, and automatically switching a view displayed on the user interface. The switched view can be switching from a single-user model to a multi-user model. In another example, a state machine transition can result in establishing connections between devices (e.g., phones or laptops) associated with the users that used the pen.

Abstract: The disclosed technologies address various technical problems, including improving human-computer interaction, by augmenting the functionality provided by user input devices using a digital glove. For example, a digital glove can be utilized to provide pressure sensitivity for non-pressure sensitive touchscreen devices, attribute input made with a digital pen to a user wearing the digital glove, augment the functionality provided by mice and other types of handheld user input devices, augment the functionality provided gaze tracking systems, improve camera-based motion tracking systems, and to augment the functionality provided by speech recognition systems.

Abstract: Techniques for visual selection and grouping are described. In at least some embodiments, multiple visuals can be selected and grouped such that visuals can be manipulated as a group and various actions can be applied to visuals as a group. For example, in response to a user placing a group of visuals in a display region, the visuals can be arranged in the display region based on a specific arrangement order. According to one or more embodiments, visuals can be rearranged to reduce gaps between visuals, such as to present a consolidated view of visuals and to conserve display space. Visuals can be grouped together (e.g., based on user selection), and selectable options presented that are selectable to apply various actions to the grouped visuals.
