Our eyes continuously reveal what we attend to and intend to do, yet most user interfaces today are still fundamentally controlled through the hands — from the mouse and touchscreen to spatial interaction. Eye-hand symbiosis offers a new paradigm in which the eyes indicate attention and intent, while the hands provide confirmation and manipulation. This has the potential to advance not only XR interaction, but digital interfaces more broadly by augmenting many existing hand-driven interactions. The shift is already becoming visible in XR, where eye-hand spatial interfaces are increasingly emerging as the new standard in devices and platforms from Apple, Google, and Samsung. In this talk, I will reflect on recent scientific and industrial progress in eye-hand interaction and discuss future directions for how eye-hand symbiosis may shape the next generation of human-computer interaction.
