Optically Clear Film for Tactile Interfaces

White Papers

Mankind has used pens, pencils, scribes, and similar writing tools for thousands of years. Much of that writing has been on parchment or paper. Together, pen-and-paper have proven to be one of the most remarkable and enduring forms of communication and recording in human history.

Over the past decade, rigid glass sheets have become the de facto standard cover lens material for mobile and computing devices, replacing previously-dominant rigid plastics. This is changing. 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.
