Abstract: Systems, terminals, servers and methods are provided for weather forecasting. For example, one or more first terminals acquire environmental information corresponding to the first terminals; wherein the environmental information includes geographic location information of the first terminals and weather data corresponding to the geographic location information; the first terminals transmit the environmental information to a server so that the server acquires weather forecasting information of an area corresponding to one or more geographic locations of the first terminals based on at least information associated with the weather data corresponding to the first terminals; wherein the geographic locations corresponding to the first terminals are within the area; and the first terminals acquire the weather forecasting information of the area transmitted by the server.

Abstract: Embodiments of the present disclosure disclose a human-computer interaction method, including: acquiring positions and/or motion tracks of multiple auxiliary light sources in a captured area by using a camera; acquiring a corresponding operation instruction according to a combined gesture formed by the acquired positions and/or motion tracks of the multiple auxiliary light sources in the captured area; and executing the acquired operation instruction. The embodiments of the present disclosure further disclose a human-computer interaction terminal and system. By using the present disclosure, interference immunity of gesture input can be improved, thereby improving accuracy of manipulation.
