What is multi-touch? What is a multi-touch device?We are already accustomed to clicking on the screen of a mobile phone or tablet to move the photos in a gallery. We use different gestures to zoom or rotate, or even to delete or discard those that are not of our interest.
The times, to use an old terminal we realize that not so long ago that was not possible. First was a simple tap to select a menu; Then he added a second finger to zoom the image. Currently we find devices, as the new Nexus tablet 7 ( version 2013) incorporating up 10 simultaneously checkpoints, allowing us to play the piano with all fingers simultaneously on its surface.
In computing, multi-touch refers to a touch sensing surface’s (trackpad or touchscreen) ability to recognize the presence of two or more points of contact with the surface. This plural-point awareness is often used to implement advanced functionality such as pinch to zoom or activating predefined programs. (W)
In the picture below you can see a screen shot of a program that displays the contact points of our fingers with a touch device (with Android OS): YAMTT (Yet Another Multitouch Test).
These utilities allow, in short, to interact simultaneously on a meso-or multi-touch surface several people at once in a collaborative. Its applications in educational settings begin to be seen in the coming years. Ya tengo ganas de tener una mesa de trabajo con estas características 🙂
