Systems and methods for generating head-up displays (HUDs) using waveguides incorporating Bragg gratings in accordance with various embodiments of the invention are provided. The term HUD is typically utilized to describe a class of displays that incorporates a transparent display that presents data without requiring users to look away from their usual viewpoints. HUDs can be incorporated in any of a variety of applications including (but not limited to) vehicular and near-eye applications, such as googles, eyewear, etc. HUDs that utilize planar waveguides that incorporate Bragg gratings in accordance with various embodiments of the invention can achieve significantly larger fields of view and have lower volumetric requirements than HUDs implemented using conventional optical components.

A cockpit for a vehicle includes an interactive device and an instrument panel. The interactive device includes an entry section that collects a first voice messages produced by vehicle occupants and an output section that outputs a second voice messages to the vehicle occupants. The instrument panel is provided at a vehicle cabin front portion. The interactive device is fixed to the vehicle width direction center of the instrument panel. The entry section and output section are exposed to the vehicle cabin interior.
