Abstract: The content output device includes an information acquisition unit, a content generation unit and an output unit. The information acquisition unit acquires driving state information which is information related to a current driving state of a vehicle. The content generation unit acquires one or more content elements corresponding to a trigger condition, from among a plurality of content elements combinable with each other, when the driving state information satisfies the trigger condition, and generates an output content using the acquired content elements. The output unit outputs the output content.

Abstract: A seat includes a seating portion, a backrest, two pairs of vibrators and a vibration absorbing member, and constitutes a driver’s seat of a vehicle. The vibration absorbing member is arranged at a boundary portion between a first region and a second region of the seating portion, and is arranged at an intermediate portion between the pair of vibrators. The vibration absorbing member suppresses vibration of the vibrator from being propagated to the second region and vibration of the vibrator from being propagated to the first region. The vibration absorbing member is arranged at a boundary portion between a first region and a second region of the backrest, and is arranged at an intermediate portion between the pair of vibrators. The vibration absorbing member suppresses vibration of the vibrator from being propagated to the second region and vibration of the vibrator from being propagated to the first region.

Abstract: A vibration control device which can make a user recognize a vibration by using a plurality of vibration units appropriately is provided. In a first vibration pattern, by interposing a low-vibration period (Ti) between a first standard vibration period (T1) and a second standard vibration period (T2), a user recognizes more easily a vibration by a vibration unit which vibrates in the second standard vibration period (T2). Therefore, even when the user's weight acts on the vibration unit which vibrates in the second standard vibration period (T2) lightly, the vibration of this vibration unit is easily recognized.

Abstract: A vibration control device is provided which enables an awakening effect for a user to be increased while making it difficult to give discomfort to the user. A harmonic signal generating section of a vibration control device is configured to successively output a plurality of alternating signals for driving a vibration unit. By way of the plurality of alternating signals which is successively output and has a frequency ratio represented with a predetermined integer ratio, vibration generated with the plurality of alternating signals can more easily awaken a user while making it difficult to give discomfort to the user.

Abstract: A head-up display makes an observer visually recognize an image, which is optically reflected by a combiner, as a virtual image. The head-up display has a main body unit and an attaching unit. The main unit has a light source which is a projection unit for projecting the image. The attachment unit is configured such that the attachment unit can be attached to a sun visor that is provided to a vehicle. The joint member has a rotation shaft that rotatably joints the main unit to the attachment unit. The damper reduces vibration of the main unit in the rotational direction of the rotation shaft. When the rotation shaft of the joint member is attached to the sun visor by the attachment unit, the rotation shaft is substantially parallel to a sun visor supporting shaft so the sun visor can rotate in the direction in which the sun visor opens/closes.
