Despite their support in contemporary specifications for web-based virtual, augmented and mixed reality, such as WebXR, user interaction is limited in several ways in corresponding web applications. This paper introduces software components providing solution for two of these limitations: a lack of six degrees of freedom motion capturing for smartphone-based VR headsets and no hand gesture support for MS HoloLens. The components have been developed for LIRKIS Global - Collaborative Virtual Environments, but can be used for any web applications utilizing the A-Frame framework. The paper describes both components and evaluates their performance.
