Summary:
The paper introduces a acoustic-based recognier 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. The recognizer they made here can recognize 6 different basic shapes by obtaining about 90% accuracy with less than five minutes of training and on wide variety of surfaces.For recognition, they actually use the amplitude of waveform and figure out the shape of waveform like traiangle, rectangle, and so on. The other contribution of this paper is to introduce several example applications that can use this technology, mainly for the mobile applications.
Discussion:
Awesome idea! They used sketching sound source, which can be very useful for sketch recognition. In fact, our projects idea come from this this paper. As far as I know, this
is the first paper that show the sketching sound can be used to variety of applications in real life,especailly for the mobile devices. This work could be extend to more complicate cases, which I am trying to do.
Actually, I do not really think scrach will have good results, since it is away too noisy.
ReplyDeleteThe idea of using sound to recognize gesture is an interesting idea. I agree with that its biggest problem is the influence of noise. Not only the noise of surrounding area, but also the noise that caused during the action of drawing itself.
