Scratch Input: Creating Large, Inexpensive, Unpowered and Mobile Finger Input Surfaces
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.
Tag: Giving the Finger
I have previously witnessed many footballers getting fined (usually about 10000 euro) over giving the finger to either their own fans or the fans of the other side. But this is the first time I hear that a footballer might get jailtime over it. It is happening in Brazil, to Cristian Mark Junio Nascimento Oliveira, of the Corinthians. He is facing charges in for unsuitable behavior or lewd conduct or something like that, being prosecuted by the department of justice. Usually, footballers get the fine from their own club or from the national football league.
Do not take the following politically. I just wanted to add this case to my collection of famous gestures by public speakers caught on camera. George W. Bush is caught giving the finger in what he calls ‘a one-fingered victory salute’. According to About.com‘s D. Kurtzman this happened in Austin during the later months of Bush’s term as Texas governor. That is almost 8 years ago I think. But still people ask me whether I have seen this video. So here it is.
Which victory was Bush ‘celebrating’?
