Evaluating the influence of multimodal feedback on egocentric selection metaphors in Virtual Environments

Whether a user interface is intuitive depends amongst others on (multimodal) feedback. The addition of multimodal feedback can certainly improve interaction in Virtual Environments as it increases the bandwidth to the user. One of the most common tasks in Virtual Environments is object selection. This paper elaborates on the enhancement of some existing approaches with multimodal feedback. The proposed techniques have been evaluated through a user experiment and the results show that the addition of multimodal feedback is preferred by the user and depending on the selection metaphor, it can also speed up the interaction.
