Abstract
An information processing device includes a control unit that determines a travel path of a wheelchair. The control unit determines the travel path of the wheelchair based on information on a step existing on a road surface on which the wheelchair travels and information on a wheel of the wheelchair.
Claims16
An information processing device comprising a control unit that determines a travel path of a wheelchair, wherein the control unit determines the travel path of the wheelchair based on information on a step existing on a road surface on which the wheelchair travels and information on a wheel of the wheelchair and controls the wheelchair to travel along the travel path;
- wherein:
- when the wheelchair crosses a road, the control unit causes a display device to display a pedestrian crossing on the road surface of the road in a range including the travel path of the wheelchair;
- and
- the control unit causes the display device to display in the pedestrian crossing a range in which a height at which the wheel of the wheelchair enters the step is equal to or larger than a fourth threshold value as a travel prohibited area of the wheelchair.
An information processing method for determining a travel path of a wheelchair, comprising
- determining the travel path of the wheelchair based on information on a step existing on a road surface on which the wheelchair travels and information on a wheel of the wheelchair;
- controlling the wheelchair to travel along the travel path;
- causing, when the wheelchair crosses a road, the display device to display a pedestrian crossing on the road surface of the road in a range including the travel path of the wheelchair;
- and
- causing the display device to display in the pedestrian crossing a range in which a height at which the wheel of the wheelchair enters the step is equal to or larger than a fourth threshold value as a travel prohibited area of the wheelchair.
A terminal device mounted on a wheelchair or carried by a user of the wheelchair, wherein the terminal device acquires from an information processing device a travel path of the wheelchair determined by the information processing device based on information on a step existing on a road surface on which the wheelchair travels and a shape of a wheel of the wheelchair and controls the wheelchair to travel along the travel path;
- wherein:
- when the wheelchair crosses a road, the terminal device causes a display device to display a pedestrian crossing on the road surface of the road in a range including the travel path of the wheelchair;
- and
- the terminal device causes the display device to display in the pedestrian crossing a range in which a height at which the wheel of the wheelchair enters the step is equal to or larger than a fourth threshold value as a travel prohibited area of the wheelchair.
