Abstract: Techniques for web-based collaborative inking sessions via a computer network are described in this document. In one embodiment, a first computer can serialize detected pointer input at a first computer into data representing one or more ink objects individually representing an image or animation corresponding to the detected pointer input. The first computer can then transmit the data representing the serialized ink objects to the second computer via the computer network. Upon receiving the transmitted data, the second computer can de-serialize the received serialized ink objects, reconstruct the image or animation corresponding to the detected pointer input at the first computer, and surface, to a second user, the image or animation of the detected pointer input on a second web browser surfacing the same webpage on the second computer, thereby enabling a web-based collaboration session between the first and second users.

Abstract: Techniques for scale factor based on viewing distance are described. In at least some embodiments, a viewing distance refers to a distance at which a user typically views and/or is viewing a display device. For instance, different displays can be used in different ways and for different purposes, and thus may have different viewing distances. Techniques discussed herein consider the estimated viewing distance of a particular display in determining a scale factor to be applied to visual elements (e.g., graphics) for output via the particular display. A scale factor, for instance, can specify that visual elements are to zoomed-out or zoomed-in prior to be displayed. As detailed herein, this enables a consistent viewing experience to be maintained across different devices with different display sizes and different viewing distances.

Abstract: In one or more embodiments, a hit test thread which is separate from the main thread, e.g. the user interface thread, is utilized for hit testing on web content. Using a separate thread for hit testing can allow targets to be quickly ascertained. In cases where the appropriate response is handled by a separate thread, such as a manipulation thread that can be used for touch manipulations such as panning and pinch zooming, manipulation can occur without blocking on the main thread. This results in the response time that is consistently quick even on low-end hardware over a variety of scenarios.
