Provided are a computer system, a remote control notification method and a program. This computer system acquires an image of an IoT device, determines, from the acquired image, the IoT device which is capable of being remotely controlled by a user who visually confirms the image, and, in a position where the image of the IoT device determined to be remotely controllable is captured, displays with augmented reality that remote control is possible. Further, the computer system pre-stores images of the remotely controllable IoT device, and, on the basis of the pre-stored images of the IoT device, determines that the IoT device is remotely controllable through image recognition which involves comparing the pre-stored images with the acquired image.
