Query: Mixing Modalities of 3D Sketching and Speech for Interactive Model
  Retrieval in Virtual Reality   Sketch and speech are intuitive interaction methods that convey complementary
information and have been independently used for 3D model retrieval in virtual
environments. While sketch has been shown to be an effective retrieval method,
not all collections are easily navigable using this modality alone. We design a
new challenging database for sketch comprised of 3D chairs where each of the
components (arms, legs, seat, back) are independently colored. To overcome
this, we implement a multimodal interface for querying 3D model databases
within a virtual environment. We base the sketch on the state-of-the-art for 3D
Sketch Retrieval, and use a Wizard-of-Oz style experiment to process the voice
input. In this way, we avoid the complexities of natural language processing
which frequently requires fine-tuning to be robust. We conduct two user studies
and show that hybrid search strategies emerge from the combination of
interactions, fostering the advantages provided by both modalities.
