Abstract: In an interactive driving simulation apparatus for a two-wheeled vehicle, a real-time test drive performance by a student operator around a simulated driving route sequence is recorded. The recorded performance is later replayed for the benefit of the student, to provide real-world simulation, education, and performance evaluation. During the simulated driving, pre-recorded performance evaluation comments are selected and stored, corresponding to the student's specific performance at a traffic driving situation on the driving route sequence. Then, upon displaying of a replay screen image of the simulated driving on a display unit, when a particular traffic driving situation is arrived at, a simulated operating environment of the traffic driving situation and the selected performance evaluation comments are automatically superimposed and displayed together as a replay screen 154.

Abstract: To eliminate a wrong recognition of speech and reduce processing load to be applied to a computer in a simulation apparatus. The simulation apparatus includes a speech recognition section for referring to dictionary data in which a plurality of phrase data are recorded to specify phrase data, a dictionary selection section for selecting the dictionary data to be referred to by the speech recognition section in response to a mode, and a monitor and a motor for being operated based on an operation of rider, speech and the phrase data. The speech recognition section confirms whether or not sound inputting is valid. If the sound inputting is valid, then a speech recognition mark is displayed on a screen. One of the dictionary data is selected based on the mode. Voice of the rider and the dictionary data are referred to for searching for phrase data conforming to the recognized speech.

Abstract: A bicycle simulation apparatus includes: a steering angle sensor which detects a steering angle of handlebars; a visual display which displays scenes based on a simulated travel speed and the steering angle of the handlebars; and a crank position detector which detects rotational positions of cranks. The crank position detector includes two detected protrusions on a crankshaft and left and right approach sensors.

The bicycle simulation apparatus enables a more realistic driving simulation in consideration of rotational positions of simulator pedals and cranks.

Abstract: A communication system is provided with a group registration function, which is capable of setting a group mode with the reduced number of operation, and simply selecting one of full duplex communication and half duplex communication by a rider, as needed. When a power supply switch and a registration switch are turned on simultaneously, member ID registration is executed. When the power supply switch is turned on and then the registration switch is turned on, visitor ID registration is executed. Accordingly, the registration of a group mode can be simplified. After the registration is ended, at the time of turn-off of a visitor conversation switch, full duplex communication is performed among communication devices subjected to member ID registration, and at the time of turn-on of the visitor conversation switch, half duplex communication is performed between the master and all of the slaves.
