Optically clear film for tactile interfaces
Micah B. Yairi · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2016
For years, rigid plastics dominated as cover lenses in mobile and computing devices before being replaced by rigid glass sheets, which have become the current de facto standard. This is changing again. Optically clear, soft polymer films and film stacks now offer a promising alternative to glass. These polymer films provide a fundamentally different user experience, dramatically improving the user experience of writing and drawing, while also providing good durability. Tactus has developed an optically clear stack of polymer materials for use in a writing-first device. Details, usability studies, and performance data will be presented.
