Daito has just posted this amazing video of smart laser tracking (see below). Laser is projected onto paper and at the same time can read constraints as well as obstacles in physical world. Examples include being able to contain the laser using hands, laser behaviour on drawn paper and more.
Some note from this laser research:Â The piece is based upon a 3d tracking technology developped in our lab in 2003, using a laser diode, a pair of steering mirrors, and a single non-imaging photodetector called the “smart laser scanner” (for details, see here). The hardware is very unique: since there is no camera nor projector (with pixellated sensors or light sources), tracking as well as motion can be extremely smooth and fluid. (The laser power is less than half a milliwatt – half the power of a not very powerful laser pointer – and does not supposes any hazard). Read more
