1. An apparatus for displaying information on a vehicle, the apparatus comprising:
an information acquiring unit that acquires speed information of the vehicle and status information concerning a status of the vehicle, the status information including slope information and acceleration information; and
a display control unit that controls a display screen in such a manner that the speed information and the status information acquired are displayed simultaneously,
wherein
the speed information is displayed in a substantially circular area on the display screen, and
the slope information and the acceleration information are displayed substantially diagonal each other across the substantially circular area.
2. The apparatus according to claim 1, wherein
the speed information is displayed in the substantially circular area with a numeral,
the status information further includes at least one of engine revolutions-per-minute information, angular-velocity information, lateral-gravity information, voltage information, direction information, time information, latitude and longitude information, torque information, and horse-power information, and
the status information is displayed surrounding a part of an outer periphery of the substantially circular area.
3. The apparatus according to claim 1, wherein the substantially circular area is displayed substantially in a center of the display screen.
4. The apparatus according to claim 1, wherein the display control unit controls the display screen in such a manner that a level of a display changes dynamically in an up-down direction according to amounts of changes in slope or acceleration based on the status information.
5. The apparatus according to claim 1, wherein the display screen is included in an in-vehicle navigation system.
6. A method of displaying information on a vehicle, the method comprising:
acquiring speed information of the vehicle and status information concerning a status of the vehicle, the status information including slope information and acceleration information; and
controlling a display screen in such a manner that the speed information and the status information acquired are displayed simultaneously, wherein
the speed information is displayed in a substantially circular area on the display screen, and
the slope information and the acceleration information are displayed substantially diagonal each other across the substantially circular area.
7. The method according to claim 6, wherein
the speed information is displayed in the substantially circular area with a numeral,
the status information further includes at least one of engine revolutions-per-minute information, angular-velocity information, lateral-gravity information, voltage information, direction information, time information, latitude and longitude information, torque information, and horse-power information, and
the status information is displayed surrounding a part of an outer periphery of the substantially circular area.
8. The method according to claim 6, wherein the substantially circular area is displayed substantially in a center of the display screen.
9. The method according to claim 6, wherein the controlling includes controlling the display screen in such a manner that a level of a display changes dynamically in an up-down direction according to amounts of changes in slope or acceleration based on the status information.
10. The method according to claim 6, wherein the display screen is included in an in-vehicle navigation system.
11. A computer-readable recording medium that stores a computer program for displaying information on a vehicle, wherein the computer program causes a computer to execute
acquiring speed information of the vehicle and status information concerning a status of the vehicle, the status information including slope information and acceleration information; and
controlling a display screen in such a manner that the speed information and the status information acquired are displayed simultaneously, wherein
the speed information is displayed in a substantially circular area on the display screen, and
the slope information and the acceleration information are displayed substantially diagonal each other across the substantially circular area.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A rolling toy comprising:
a chassis,
an electrical power source attached to the chassis,
a remote signal receiver,
an electric motor attached to the chassis and receiving power from the power source in response to a signal received by the remote signal receiver,
a pair of riding surface-engaging wheels mounted co-axially to the chassis and capable of rotating independently of one another, and wherein at least one of the wheels is driven to rotate by the electric motor, wherein one of the wheels is connected to an input gear, and the electric motor drives the input gear, and
a dome-shaped profile formed on each wheel and adapted to bear upon the riding surface to assist in righting the toy, should it topple in use.
2. The rolling toy of claim 1, wherein the chassis forms a hub flanked at opposed sides by the riding service-engaging wheels.
3. The rolling toy of claim 2, further comprising an arm extending radially from the chassis and having an end that can engage with a riding surface to restrict counter-rotation of the hub.
4. The rolling toy of claim 3 wherein the arm is light-transmissive, and further comprising a light source at the chassis for directing light into the arm.
5. The rolling toy of claim 4 wherein the light source produces intermittent light, or light of differing colour.
6. The rolling toy of claim 1, wherein both of the wheels are driven to rotate by the electric motor.
7. The rolling toy of claim 1, comprising a further electric motor and wherein the other wheel is driven to rotate by the further electric motor.
8. The rolling toy of claim 7, wherein the other wheel has an input gear, and the further electric motor has an output sprocket that drives the input gear.
9. The rolling toy of claim 1 further comprising a speaker mounted to the chassis and a sound generator from which the speaker receives an electrical signal.
