Current wearable interfaces are designed to support short-duration tasks known as micro-interactions. To support productive interfaces for everyday analytic tasks, designers can leverage natural input methods such as direct manipulation and pointing. Such natural methods are now available in virtual, mobile environments thanks to miniature depth cameras mounted on headworn displays (HWDs). However, these techniques have drawbacks, such as fatigue and limited precision. To overcome these limitations, we explore combined input: hand tracking data from a head-mounted depth camera, and input from a small ring device. We demonstrate how a variety of input techniques can be implemented using this novel combination of devices. We harness these techniques for use with Spatial Analytic Interfaces: multiapplication, spatial UIs for in-situ, analytic taskwork on wearable devices. This research demonstrates how combined input from multiple wearable devices holds promise for supporting highprecision, low-fatigue interaction techniques, to support Spatial Analytic Interfaces on HWDs.
