Abstract: An app and associated toy are disclosed that allow a smartphone user to play remotely with a pet by controlling the movement of a remote spot of light. A remote camera allows the user to see and record video of the pet playing. The light spot is controlled by moving a cursor, or by directly moving the light spot on a touch video screen. The viewer also has the option to have the spot follow a predetermined path. By starting the play at the same time as presenting a noise designed to attract a pet, the pet is conditioned to associate that noise with playing. This allows the pet to be summoned to the game. In a more advanced version, the app also controls a treat dispenser for rewarding the pet for playing. An RFID tag on the pet allows the light source to be shone near to the pet.
