摘要：

Hand input offers a natural, efficient and immersive form of input for virtual reality (VR), but it has been difficult to implement on mobile VR platforms. Accurate hand-tracking requires a depth sensor and performing computer vision on a smartphone is computationally intensive, which may degrade the frame rate of a VR simulation and drain battery life. PAWdio is a novel 1 degree of freedom (DOF) hand input technique that uses acoustic sensing to track the relative position of an earbud from a headset that the user holds in their hand. PAWdio requires no instrumentation and its low computational overhead assures a high frame rate. A user study with 18 subjects evaluates PAWdio with button input that is commonly available on VR adapters. Results with a 3D target selection task found a similar accuracy and usability, a significantly slower performance, but higher immersion for PAWdio. We discuss limitations and game applications of PAWdio.
