the vehicle:
• Driver area
– Head-up display (HUD) (limited to driver, or augmented over a big part or the whole
windshield)

– Touch screen in the steering wheel
• Loudspeakers either in doors, or passenger specific for individual sound bubbles in headrests
– Acoustic warning signals
– Text-to-speech (e.g., reading of messages, mails, other information)
– Sound (e.g., multimedia content, phone/video conferencing)

• Center stack display(s)

8.1 The acoustic system in the vehicular multimedia

8.1.1 Background
As stated in the terms of reference of the FG-VM, a vehicle may become a user’s third entertainment
space, and could be highly personalized. A VMS may support multiple screens and may be used not
only to listen to radio but also possibly to watch television, movies, play games, either collectively or
individually. At the same time a vehicle may comprise a voice recognition or natural language
processing system. It is expected that one or more multimedia sources and users interacting with one
another or with a multimedia system will interfere with the voice commands.
