A method for showing objects in an augmented reality environment includes the steps of an Augmented Reality (AR) device obtaining spatial information and object identification (ID) from an anchor device. The AR device obtains parameters of the objects from a cloud system. The parameters of an object include the image of the object, the audio of the object, and a first spatial relationship between the object and an anchor device. The AR device obtains a second spatial relationship between the AR device and the anchor device. A third spatial relationship between the object and the AR device can be obtained according to the first spatial relationship and the second spatial relationship. The image of the object and the audio of the object is displayed or projected in the AR device according to the third spatial relationship.
