Visualization of Remote Touch Panel for Dialysis Patient on Prototype Bed

Work environment is required for patients in artificial dialysis. We have developed a prototype bed with a ceiling display and non-contact operation function. Virtual touch panel of non-contact operation function using Remote Touch Panel is not visualized. We propose the virtual touch panel visualized by shapes and colors of projection mapping. From the experimental results, the most selected shape pattern is "White Line and Blue Space" with "Back" decision. It is considered that the "Line" has a role as a decision position. And the "Space" has a role to feedback that it has approached the decision position.
