Abstract: A display unit is present in a space different from an input and output screen displayed in a three-dimensional space, and a control unit displays the input and output screen as an optical image formation of light progressing in a direction of a user so that no one other than the user is able to photograph the input and output screen.

Abstract: A hybrid vehicle includes a first gear mechanism which transmits the power of the internal combustion engine to the motor generator side, while accelerating the power between the internal combustion engine and the motor generator; a second gear mechanism which transmits the power of the motor generator side to a vehicle drive shaft, while decelerating the power between the motor generator and the vehicle drive shaft; a third gear mechanism which transmits the power of the drive motor side to the vehicle drive shaft, while decelerating the power between the drive motor and the vehicle drive shaft; a clutch mechanism which switches connection and disconnection between the drive shaft of the motor generator and the first gear mechanism or the second gear mechanism; and a control device which controls the clutch mechanism. The motor generator is not connected to both the vehicle drive shaft and the internal combustion engine at the same time at the time of normal traveling.

Abstract: A series hybrid vehicle is equipped with an engine, a first motor generator, and a second motor generator. The vehicle has a reduction gear that is a first power transmission mechanism for engaging the engine with the first motor generator, a reduction gear that is a second power transmission mechanism for engaging the first motor generator with a vehicle drive shaft, and a clutch that is capable of engaging the first motor generator with one of the two reduction gears in a switching manner. The vehicle further has a transmission that switches between transmission gear ratios and engages the second motor generator with the vehicle drive shaft.
