Fujitsu and Sapporo Shirakaba-dai Hospital announced that it jointly developed a clinical appointment guidance system that uses color e-paper. The system has began full operation at the hospital. The new system guides patients to examination rooms or diagnostic testing rooms and is wirelessly connected to an electronic medical record system. Patients can view in real-time their place in queue when waiting to see their doctor.
We're guessing Fujitsu is using their own color e-paper technology. Fujitsu announced a hospital registration system back in July 2010, which used monochrome E Ink, but the new one uses color e-paper.
