Query: Comparison of a Head-Mounted Display and a Curved Screen in a
  Multi-Talker Audiovisual Listening Task   Objectives: Virtual audiovisual technology and its methodology has yet to be
established for psychoacoustic research. This study examined the effects of
different audiovisual conditions on head-yaw and eye-gaze direction as well as
on preference when listening to multi-talker conversations. The study's goal is
to explore and assess audiovisual technologies in the context of hearing
research. Design: The participants listened to audiovisual conversations
between four talkers. Two displays were tested and compared: a curved screen
(CS) and a head-mounted display (HMD). Using three visual conditions
(audio-only, virtual characters and video recordings), three groups of
participants were tested: seventeen young normal-hearing, eleven older
normal-hearing, and ten older hearing-impaired listeners. Results: When there
were no visual cues, participants tended to look ahead; when visual information
was available, they looked at the target talker. Participants generally turned
their head close towards the target talkers when presented as video than
virtual characters. In addition, an effect of display showed that in the most
extreme case when the talker was at 45 degrees, they turned closer when wearing
the HMD than when viewing the curved screen. Open interviews showed that the CS
was preferred over the HMD for older participants and that video recordings
were the preferred visual condition. Conclusions: Using different audiovisual
setups may lead to slightly different movement behavior in terms of head yaw
and horizontal gaze. These differences, as well as preference for specific
audiovisual technologies, should be taken into account when designing and
comparing experiments.
