FlexStylus: Leveraging Bend Input for Pen Interaction
summary
FlexStylus is a flexible pen that uses four fiber-optic deformation sensors and an IR LED to measure both the amount and direction of barrel bend, giving two degrees of freedom beyond x,y. Prototype includes a connective nib and a 4 cm bending section; interaction sets map grips to brush size, color wheel pointing, and in-air scrolling. A lab study with 18 participants finds absolute bending more accurate than pressure overall, with similar dynamic and static behaviors.
