Low-level Voice and Hand-Tracking Interaction Actions: Explorations with Let's Go There
Jaisie Sin, Cosmin Munteanu · 2021
Hand-tracking allows users to engage with a virtual environment with their own hands, rather than the more traditional method of using accompanying controllers in order to operate the device they are using and interact with the virtual world. We seek to explore the range of low-level interaction actions and high-level interaction tasks and domains can be associated with the multimodal hand-tracking and voice input in VR. Thus, we created Let's Go There, which explores this joint-input method. So far, we have identified four low-level interaction actions which are exemplified by this demo: positioning oneself, positioning others, selection, and information assignment. We anticipate potential high-level interaction tasks and domains to include customer service training, social skills training, and cultural competency training (e.g. when interacting with older adults). Let's Go There, the system described in this paper, had been previously demonstrated at CUI 2020 and MobileHCI 2021. We have since updated our approach to its development to separate it into low- and high-level interactions. Thus, we believe there is value in bringing it to MobileHCI again to highlight these different types of interactions for further showcase and discussion.
