내가 가장 좋아하는 논문중 하나. Chris Harrison 이름이 많은 연구자들에게 전파될수 있게한 2008 년 그의 데뷔작.
We present Scratch Input, an acoustic-based input technique that relies on the unique sound produced when a fingernail is dragged over the surface of a textured material, such as wood, fabric, or wall paint. We employ a simple sensor that can be easily coupled with existing surfaces, such as walls and tables, turning them into large, unpowered and ad hoc finger input surfaces. Our sensor is sufficiently small that it could be incorporated into a mobile device, allowing any suitable surface on which it rests to be appropriated as a gestural input surface.
Several example applications were developed to demonstrate possible interactions.
We conclude with a study that shows users can perform six Scratch Input gestures
at about 90% accuracy with less than five minutes of training and on wide variety of surfaces.
