There’s sensor which looks like just a stethoscope head which is the key player here plays with all the input balls. This is built based on acoustic based input technique which that relies on the unique sound produced when we scratch on any surfaces. The word acoustic is- a sound wave that is defined by science, means when we produce any kind of sound either by tapping or by scratching or by any means that signal or that wave is a part definition of acoustic. This sensor catches the signal that comes from tapping or scratching any surface (wooden table, fabric, wall paint etc.) with finger nails. This sensor is easily coupled with those surfaces and programmed with some gestures of fingers that are compiled to some pre configured commands, which results what was programmed previously. Just like microprocessor nothing else.
The Sensor which catches the scratched input
Now if you drag your finger, that sensor can sense it and produce some wave which first caught by a computer and that gives the command to silent a mobile, to talk with someone, to make the phone in speaker. Steps are somewhat like this:
1. Drag finger across the surface in any gesture
2. Which caught at a distance by the sensor(connected with mobile phone, which is connected with the computer also)
3. Sensor is connected to the computer
4. Computer caught the wave and monitor the signal
5. Pre defined commands executes according to the gesture of the finger drag)
Sensor is placed on wall
So this is amazing without a touch screen technology that comes up recently in public’s hand. This sensor is built very small which can be placed in a mobile device also. The sensor turned into a large, unpowered and ad hoc finger input surfaces. It is concluded that users can perform six different kinds of scratch input gestures at about 90% accuracy with less than a five minutes of training and upon variety of surfaces. The sensor even senses a scratch at about a distance from 8 meter where the sensor is placed. The sound will be much clear as the scratch is done closer to the sensor. So even if you are sitting in a distance but the surface is same means, long wooden table, wall paint, fabric, etc. Then definitely you will be doing the same what you could do in near. But it can’t catch the signal if the sensor and the scratch input both are placed in different surface. It means surface matters the signal.
Computer catches the signal and getting the web
Who knows that this Scratch Input Technology becomes vaster? The study is now concluded, not the research. Just imagine what it could be afterwards, you can place your mobile phone in your desk and just with some small scratch input gestures you could do all the operations what is today done by holding the device and either by touching the screen or by tapping the buttons. In future days there is a plan to incorporate this technology in Windows Mobile Phones. Now, days are coming with such playful, funny and amazing devices that will need just a move in the air, nothing else.
This fabulous concept or you can say the marriage of simplicity and technology is developed by a person whose name I have heard just some days before, he is another rising sun in the battle field of techno stuffs. He is CHRIS HARRISON, researching in Carnegie Mellon University in 3rd year. He is also a Microsoft research Ph.D. so just think why Microsoft should worry about a 1% downfall in market shares ($219.58 billion). It knows what comes in future ............... and what “Gift” it’s going to give us.
