1. Field of the Invention
The present invention relates to an information processing system, a mobile terminal, a server apparatus, a method for processing information, and a non-transitory computer readable storage medium.
2. Description of the Related Art
A technique has conventionally been known that collects motion information indicating motions of an indefinite number of people such as pedestrians, thereby detects the occurrence of an event (an abnormality, an intriguing event, or the like) to which a plurality of people pay attention, and estimates an area in which the event is occurring.
For example, a technique is known that collects positional information of mobile terminals carried by pedestrians or other people, thereby quickly detects a situation in which a plurality of people are stopping because of the occurrence of an abnormality, and identifies an area in which the abnormality is occurring.
Another technique is known that installs an imaging apparatus at a predetermined position, detects sight lines of a plurality of people using image information obtained by imaging an indefinite number of people such as pedestrians to identify an area on which the sight lines are focused, and thereby detects that an event has occurred in that area.
However, simply by collecting the positional information of the mobile terminals carried by pedestrians or other people as described above, it is difficult to estimate the area in which the abnormality is occurring with high precision. This is because when people are looking at an abnormality at a distance, the positional information of positions at which the people are stopping does not necessarily represent the area in which the abnormality is occurring, for example.
In contrast, the method that identifies the area on which the sight lines are focused to detect the area in which the abnormality is occurring can avoid this problem. However, there is a problem in that when sight lines of an indefinite number of people are attempted to be monitored to constantly detect an area in which an abnormality is occurring, a huge amount of data is required to be processed at high speed, causing calculation costs.
