Abstract: Wearable device, as a representative of artificial intelligence, not only highlights the development of technology, but also has aesthetical significance as ornaments, and the data collected by the device can also be regarded as the object of aesthetics. The wearable device has extended human senses as a medium attached to human bodies and then has the characteristics of the human body. Its sensing technology and receiving device have become part of the body, presenting an aesthetic, symbiotic, dynamic relationship. The wearable device enhanced human’s contact and experience with the world and themselves, allowing them to experience both the real life and the virtual world. In this era of body carnival, rather than wild rejoice, the attachment of wearable device to human bodies has brought about physical rationality, which is different from instrumental rationality. Human beings must uplift their subjective consciousness and pursue rational knowledge about their health and wellbeing above the design concept of smart wearable device and the concept of wearing it.

Key words: wearable device, medium, aesthetic activity, AI
