A touch screen digital interface that allows more than one touch at a time is called multi-touch. This “multi-touch” display technology adds functions such as allowing a person to easily zoom in and out of pictures and Web pages by pinching the screen with two fingers similar to the iPhone but very much more impressive with the large scale touch screen.
The full power of multi-touch technology is unleashed in screens far larger than those on found on phones. Technology is racing ahead and now there are touch screens that allow 10, 20, or even more fingers to multi-touch. Applications ranging from wall mounted interactive touch screens to touch-screen tables and digital walls–any of which could be manipulated by more than just one person at a time.
Multi-touch technology enables multiple users to gather around a large touch screen which becomes seriously exciting as multiple users become collaborators in their efforts. This collaboration can take on many forms, from brainstorming sessions using networked touch screens to animation, data entry, writing, drawing. Even collaborations at which six hands can mould an image or bring in parts to form a consolidated image or collage.
Touch tables allow groups to sit around in comfort to collaborate on projects. These multi-touch screens are going to be a really important tools for collaborative learning, training and expression in the future.
Imagine a classroom where every child moves at his own pace. Where lesson plans are customized to every student抯 individual strengths and weaknesses. Where a teacher spends less time grading papers and more time interacting one-on-one with students who are struggling ?or who need to move ahead faster. Where real-time data on student progress makes a once-a-year standardized test obsolete.
Or consider a six year old severely affected by autism with severe learning difficulties who finds many social situations very difficult and hasn’t spoken for three years but uses her touch screen as a way of learning and communicating that plays to her strengths.
The touch screen revolution is creating some unexpected consequences: controlling information and images with fingertips–is finding its way into many traditional and familiar settings.
Touch screens offer some really intriguing options. Touch screens make excellent interactive retail kiosks and can be modified to run touch-activated reservation and inventory software. They can even be shared work terminals on which students, customers and staff collaborate, even to fill out complex forms in a medical setting and in waiting rooms, for example which could dramatically improve the speed and accuracy of entering data.
They can operate as an interactive terminal. They can handle fast database-intensive applications. And screens are big enough to allow even the most computer illiterate to enter data, manage tasks or otherwise get work done.
These high-quality displays support full-HD resolution, making it ideal for an interactive point-of-sale terminals.
Using a stylus pen on tablets has long been favoured by the digital illustration community and works equally as well on a Touch screen to produce drawings, animations and 損aintings?Drawing with a stylus pen on a touch screen is brilliant as it employs a defined tip to gain definition and accuracy. Writing takes the prize, without a doubt and many software packages can convert this to text. Users can jot down notes at varying angles without ever needing to rest on the touch screen bezel to be comfortable.
A stylus pen is absolutely top-tier for both writing and sketching. However, if you抮e looking for a simple navigation device a finger will do the trick with ease.
Touch screen technology is not limited to indoor use or dry environments as sealed, robust and durable screens can be used outdoors for restaurants, railway stations, car parks and even in damp or hazardous environments like operating theatres, swimming pools or factories
