Abstract

This article describes a benchmark for evaluating adequacy of input devices for bimanual direct interaction techniques typically found in VR/AR applications. The benchmark implements a puzzle-like scenario inspired from shape and color sorting games, in which the user manipulates the position, rotation and scale of 3D spheres. The continuous interactions are combined with multimodal state-change actions using either a button or speech interface. A follow-up usability study utilizes the benchmark to evaluate the performance of one professional and one consumer-grade tracking system for both state-changing interfaces. The results reveal similar adequacy for both tracking systems under both multimodal conditions.
