A device is provided that includes a vision camera, a sensor module, a communication module, an output module, a memory, and a processor operatively connected to the vision camera, the sensor module, the communication module, the output module, and the memory. The processor is configured to connect to an external electronic device via the communication module, receive, from the external electronic device, location information of the external electronic device and determine an expected moving path, recognize an obstacle on the expected moving path based on at least one of the location information of the external electronic device, an image acquired from the vision camera, a sensor value acquired from the sensor module, and information collected from another device located on a road through the communication module, and determine risk of collision between the external electronic device and the obstacle so as to provide a risk notification through the output module.
