(Phys.org)—Touchscreen computing as an "experience" has only just begun. Working on ideas they seeded at Carnegie Mellon, computer-human interaction researchers have started a San Jose, California, company Qeexo, that features ...
Using tiny radiation pressure forces—generated each time light is reflected off a surface—University of Oregon physicists converted an optical field, or signal, from one color to another. Aided by a "dark mode," the conversion ...
