    Current virtual environment (VEs) input techniques often overlook speech as a useful control modality. Speech could improve interaction in multimodal VEs by enabling users to address objects, locations, and agents, yet research on how to design effective speech for VEs is limited. Our paper investigates the effect of agent feedback on speech VE experiences. Through a lab study, users commanded agents to navigate a VE, receiving either auditory, visual or behavioural feedback. Based on a post interaction semi-structured interview, we find that the type of feedback given by agents is critical to user experience. Specifically auditory mechanisms are preferred, allowing users to engage with other modalities seamlessly during interaction. Although command-like utterances were frequently used, it was perceived as contextually appropriate, ensuring users were understood. Many also found it difficult to discover speech-based functionality. Drawing on these, we discuss key challenges for designing speech input for VEs

    The Virtual Jumpcube is a virtual reality setup from 2015 that allows for jumping and flying in audiovisual virtual environments. Recently, we have included several haptic and olfactory stimuli that should further increase the degree of immersion in the experienced virtuality. These additional media channels were tested by the participants of several events and the feedback of 196 jumpers was gathered in a questionnaire. In this paper, we describe the stimulation hardware and software as well as the performed experiment and we present the major findings of the evaluation. It shows that if employed correctly, haptic and olfactory stimuli can enhance immersion and user experience significantly. Major success factors appear to be the amplitude and frequency of stimulation as well as the temporal synchronization with the other media channels, in particular the visual stimuli
