Information providing device, information providing system, information providing method, and non-transitory computer readable medium

An information providing method comprising:

• storing area designation information for designating an area set on a route to a target, an angle threshold value which is an entry angle threshold value or an exit angle threshold value set in the area, and content information about the target in association with each other;
• acquiring position information about a user terminal possessed by a user;
• specifying a movement angle indicating an angle at which the user enters or exits the area, by using the position information about the user terminal;
• acquiring a time when the user enters the area or exits the area;
• based on the acquired time satisfying a predetermined time period, acquiring an adjustment value corresponding to the predetermined time period, and adjusting the entry angle threshold value or the exit angle threshold value according to the adjustment value;
• and
• controlling provision of content information based on a result of comparison between the specified movement angle with the adjusted entry angle threshold value or the adjusted exit angle threshold value.

A non-transitory computer readable medium storing a program for causing a computer to execute processing of:

• storing area designation information for designating an area set on a route to a target, an angle threshold value which is an entry angle threshold value or an exit angle threshold value set in the area, and content information about the target in association with each other;
• acquiring position information about a user terminal possessed by a user;
• specifying a movement angle indicating an angle at which the user enters or exits the area, by using the position information about the user terminal;
• acquiring a time when the user enters the area or exits the area;
• based on the acquired time satisfying a predetermined time period, acquiring an adjustment value corresponding to the predetermined time period, and adjusting the entry angle threshold value or the exit angle threshold value according to the adjustment value;
• and
• controlling provision of content information based on a result of comparison between the specified movement angle with the adjusted entry angle threshold value or the adjusted exit angle threshold value.
