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.
