Engineers at the University of Washington created the device by hollowing out a ballpoint pen and sticking two optical fibers through the center. One fiber emits light onto a writing pad that is ...

In a Macgyver-esque approach, the researchers hollowed out a ballpoint pen and inserted two optical fibers connected to a light-tight box ... a computer, pen, fiber optics, wooden pad and printed ...

how can you use a fibre-optic device to track handwriting?” How it works To create the system, Lewis and fellow engineers Frederick Reitz and Kelvin Wu hollowed out a ballpoint pen and inserted two ...

Researchers say they have created fiber cables that can move data at 99.7 percent of the speed of light, all but eliminating the latency plaguing standard fiber technology. There are still data ...
