Publisher Summary Technology is socially invisible when it fits a given culture’s tacitly agreed-upon definition of the unremarkable. This chapter sheds light on track lighting technology. Track lighting is a near to invisible ubiquitous technology, but it is neither literally invisible, nor does it attempt to be. It is embedded in a social context within which it is unremarkable, but it still has a user experience for a range of audiences. Track lighting is a rare technology in how close it can get to social invisibility. Most tools are purposefully visible. They advertise themselves, their function, and their social role prominently through their appearance. Describing technology as a distraction from everyday life underestimates the role technology plays in creating meaning in life. In many ways, the use of technology is the business and pleasure of life. Ubiquitous computing user experience design has only occasionally embraced this potential. Mostly, it has been stuck in one of two communities of practice: consumer electronics and academic research. The world of consumer electronics creates popular, highly visible, emotionally rich, but short-term and shallow user experiences. Academia creates powerful infrastructures and thoroughly researched user experiences that tend to be emotionally cold and functionally irrelevant to most people.
