Abstract: In a first area in a virtual space, an example of an information processing system renders a first shadow positioned in a first direction from an object, and a second shadow positioned in a second direction from the object. The information processing system renders a third shadow positioned in the second direction from the object, in a second area darker than a first reference area corresponding to a range in the first area. The information processing system renders the third shadow such that a color difference between a color in a second reference area corresponding to a range, in the second area, in which the third shadow is not positioned, and a color in the area of the third shadow is greater than a color difference between a color in the first reference area and a color in the area of the second shadow.

Abstract: A notification server, notification method and notification program to perform watch over a person to be watched who uses on-demand transportation. A transceiver part receives boarding/alighting information comprised of a date and time of boarding/alighting, a stopping point of a vehicle and a name of a boarding person or a name of alighting person transmitted from an information terminal apparatus mounted on a shared vehicle, and a notification information generating part acquires a notifying destination associated with the received name of the boarding person or the name of the alighting person from a notifying destination storage part and generates notification information addressing to the acquired notifying destination, and a transceiver part transmits the generated notification information.
