Abstract: Embodiments of this application disclose an interaction information obtaining method performed at a target user terminal. After detecting, on a virtual map preset in an interaction application, a trigger operation performed on a target POI identifier, the target user terminal obtains first location information of the target user terminal by using the virtual map and second location information corresponding to the target POI identifier on the virtual map. The target user terminal detects a distance difference between the first location information and the second location information. When the distance difference satisfies a preset distance range, the target user terminal sends, to an interaction server, an interaction information request carrying the target POI identifier and receives interaction information corresponding to the target POI identifier from the interaction server and then displays the interaction information on the virtual map.
