"Bonfire, a self-contained mobile computing system that uses two laptop-mounted laser micro-projectors to project an interactive display space to either side of a laptop keyboard. Coupled with each micro-projector is a camera to enable hand gesture tracking, object recognition, and information transfer within the projected space. Thus, Bonfire is neither a pure laptop system nor a pure tabletop system, but an integration of the two into one new nomadic computing platform."

Bonfire in Action – Practical implementation of Bonfire-equipped laptop
"The following scenario illustrates the rich, nomadic interactions that Bonfire could enable. Jane, a college student, takes her Bonfire-equipped laptop to her favorite coffee shop on a Saturday morning to complete a lab report for botany class.
When she opens her laptop, Bonfire's two mounted cameras capture the table, loading settings to automatically adjust the projection to the surface. Jane places her mobile phone on the table beside her laptop, and digital photos from a recent nature hike "spill" out from the phone onto the table. In one brush of the hand, she moves them to her laptop. She puts on headphones and taps the play button on a music player projected on her laptop's other side. When Jane sets her coffee next to the laptop, Bonfire recognizes the cup and opens a spreadsheet detailing how much money Jane has spent in the last month on coffee. A second spreadsheet graphs her caloric intake. Later, a friend stops by, so Jane removes her headphones to say hello, placing them on the table within Bonfire's view. Conveniently, Bonfire pauses the music, which it resumes once Jane picks the headphones up from the table. Later, Jane needs a figure from a botany textbook in her report, so she places the book in Bonfire's view. With a press of a button, the image from the book is captured onto her laptop, where it appears in her Word document."
