Arm discomfort is a common issue in Cross Reality applications involving prolonged mid-air interaction. Solving this problem is
difficult because of the lack of tools and guidelines for 3D user interface design. Therefore, we propose a method to make existing
ergonomic metrics available to creators during design by estimating the interaction cost at each reachable position in the user´s
environment. We present XRgonomics, a toolkit to visualize the interaction cost and make it available at runtime, allowing creators
to identify UI positions that optimize users´ comfort. Two scenarios show how the toolkit can support 3D UI design and dynamic
adaptation of UIs based on spatial constraints. We present results from a walkthrough demonstration, which highlight the potential of
XRgonomics to make ergonomics metrics accessible during the design and development of 3D UIs. Finally, we discuss how the toolkit
may address design goals beyond ergonomics.
