Helvetical » I am Ad Taylor. Chris Harrison - Scratch Input. 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.
Coding A HTML 5 Layout From Scratch. Advertisement HTML5 and CSS3 have just arrived (kinda), and with them a whole new battle for the ‘best markup’ trophy has begun.
Truth to be told, all these technologies are mere tools waiting for a skilled developer to work on the right project. As developers we shouldn’t get into pointless discussions of which markup is the best.
