Abstract: Recent technical advances have expanded the breadth, scope, and affordability of virtual reality (VR) and augmented reality (AR) systems. More people can use VR and AR systems than ever before. However, hand-held physical controls for these systems have not made similar advances yet. For this reason, it remains difficult for developers to create applications that take advantage of the full range of human abilities. In this proposal, we describe a system and method for combining off-the-shelf smartwatches with a set of inexpensive grips or sheaths to control VR/AR systems. With our approach, all of the computation and power for the controller derive from the smartwatch unit, allowing the grips to take almost any form, and allowing developers and designers to integrate a much wider array of interaction styles into their applications.
