Multi Touch Screens What Is Multi Touch?

Unlike single touch input – where s can select a single point, drag and drop, push and slide with only a single finger or stylus.

Multi touch Technologies enable devices to recognize and respond to touch inputs at multiple locations simultaneously.

A Brief History of Touch Technology • The beginnings of multi-touch roughly somewhere into the early 1970s. • Although a first touch screen was introduced in 1972 with the PLATO IV • Touch Screen Terminal, a multi-touch device did not come up until 1981, when Jack Rebmann produced a Tactile Array Sensor for Robotics the usage of which is described by Wolfeld • The Touchscreen revolution in display interfaces has been going strong since Apple introduced the iPhone in 2007.

How it works ? It is developed on SURFACE Platform that works on Sensors. Sensor allows a display to recognize fingers, hands, and objects placed on the screen, enabling visionbased interaction without the use of cameras. The individual pixels in the display see what’s touching the screen and that information is immediately processed and interpreted.

It Works on:  Capacitive Technologies  Surface Capacitive Technology or Near Field Imaging (NFI)  Projected Capacitive Touch (PCT)  Mutual Capacitance  Self-Capacitance

Benefit ? The Benefits Of Multi Touch Over Single Touch

Quite simply, multi touch input expands the range of functionality these devices can . Two fingers (or activation points) allow s, for example, to zoom in/out or rescale the display, with the right software. The power of this enhanced functionality becomes immediately apparent when we look at industrial applications.

Advantages  Another specific positive aspect of multi-touch lies within the use of simultaneously handled input devices.  As s can employ both their hands (and many fingers) or also different devices in combination with their hands at the same time.  They are able to make significant improvements regarding the time a task takes to be completed.  s need to be somewhat acquainted with the handling, but on simple and intuitive systems, this seems to be no problem.  Apart from simultaneous usage of hands or devices, you can also extract a lot of information out of a single means of input.  Touches can be varied in pressure sensitivity and angle (on several axes) and hands can be used to express a variety of gestures by tilting, flicking and catching or forming any conceivable kind of sign  Furthermore, multi-touch opens a whole new set of possibilities for applications since multi-touch implies not only multiple hands or devices but also multiple persons.  This enables the creation of reasonable collaborative touch systems, in which several s can interact with the screen as well as with each other simultaneously.

Added Advantages • Browse images or screenshots of all your usual documents and manipulate them with multi-touch gestures. • Open the original file, video or even a website, directly from the application • We can customize any thing • Saving or arranging made easy • Professional Productivity transform the way we work • Navigate Multi page formats • And create links to any external file or application • Easy to create multiple page formats

Disadvantages • occlusion : On the negative side, multi-touch systems complicate the occlusion problem, as several fingers, hands or devices are clouding even more parts of the touch screen than on single touch devices. • This can, however, be eased by using clever interface design approaches, • Another basic issue is the fat finger problem which requires designers to use interaction elements of a • certain minimum size, in order to be precisely touchable by human fingers. • As multi-touch systems mostly rely on touch screens rather than touch tablets without display, you always need to be able to look at the surface and get discernible display in formation

You Can Also • Visualize your data & assets through an interactive interface. Gain critical insight from massive amounts of data. Directly manipulate objects and analytic views with a multi-touch interface • Multi-touch helps to visualize, control and analyse 3D models using the most intuitive interface. Multi-touch is the future of 3D design. Great for CAD, automobile, aerospace, manufacturing, real estate and medical industries

• With the Air Screen, exchanging conference material and information becomes astonishingly fast and convenient. Gone are the days when lumber some paper leaflets and materials and upsetting cables and wires were indispensable part of a meeting. With Air Screen, a mere touch and swipe will do

Industries where the Multi Touch Technology can be used

Where Does This Technology Stand in 2010? • From these insights into touch technologies it appears that it is coming of age in current times although the early breakthroughs were made decades ago. From the innovation activity around it we can see that it really made headway in the 90’s and the last 3 years 2008, 2009, 2010 indicate that research in this space has just taken off to a new level and going by the current trend is only likely to climb even higher from here. It’s one of the extremely “hot” technologies of our times and is being sought after by a very wide of industries for various applications and is likely to squeeze its predecessors like keypad and mouse and become one of the electronic and computing interfaces of choice in the present decade. • From what we have seen through the insights revealed by IP activity and patent data we are going to see a lot more of touch related electronics in the days to come.
