The Next Goldrush? MultiTouch Screen Apps

The Holy Grail of screen technology is the gesture-activated virtual screen portrayed in Stephen Spielberg's 2002 blockbuster futuristic film Minority Report. Technologists inspired by the brilliant effects have been laboring ever since to interact with screen images, getting them to do what we want them to do by a mere wave of the hand or point of an index finger.

The iPhone's introduction of multitouch was an astounding innovation that brought Spielberg's vision closer to actualization. But the Apple device still requires physical contact with the surface of the device, whereas the next generation of virtual screens will liberate our hands from any contact whatsoever.

Where are we on the continuum between touchscreens and Minority Report's magic one?

Rebounding from an Apple-led consumer flight to handhelds, a number of PC manufacturers are developing applications designed to lure consumers back to their desks and, according to Ashlee Vance of the New York Times (PC Touch Screens Move Ahead), high on the list are touchscreens. For instance, Hewlett-Packard is pushing the TouchSmart, a desktopper with an upright screen on which you can access every function with your stylus or index finger. TouchSmart offers a variety of great applications. Vance points out that "Customers can turn these machines into bespoke kiosks for, say, ordering merchandise at a sporting event or flipping through a menu while waiting at a restaurant." Indeed, touch screens are commonly used for keeping track of tables and food orders at restaurants. They can also be embedded in homes to control lights, music, thermostat, etc., and in he kitchen to follow recipes.

However, after you've worked an iPhone screen with multitouch, one-finger functionality feels pretty limited, and we have to wonder how practical the TouchSmart approach is for business offices. Here's a simple test: next time you're sitting in front of your desktop monitor, try stretching your arm out and poking the screen every time you want to open a file, drag, drop, highlight, cut and paste or perform some other task. Do we really want to reach out to our screen every time we want to move something around or shift to another function? Don't be surprised if your arm grows weary and your back strained. Let's face it: some functions are best left to keyboard commands or mouse navigation. And - sitting at a desk is not necessarily where today's sedentary or peripatetic computer users want to be. If you're thinking about students, so am I. We'll get to them in a moment.

You can google lots of HP promotional videos and demonstrations and decide for yourself.

But soon, even five digits may be passé. Enter advanced multitouch and an Israeli outfit called N-trig. Its advanced PC screen technology called "DuoSense" enables users to use both hands as well as a pen.

N-trig is the only industry provider to offer a combined pen, touch and multi-touch solution, having overcome the technological hurdles of combining the two seamlessly in a single device. DuoSense is an intelligent digitizer, fully compatible with Microsoft natural input standards. N-trig's DuoSense digitizers are are easily integratable, support any type of LCD, keep devices slim, light and bright, can support numerous applications, and can be implemented in a broad range of products ranging from small notebooks to large LCDs.

For a cool demo check out this video of N-trig. By the way, if you're fascinated by the possibilities and have some clever ideas of your own for Windows 7 apps, N-Trig offers a $900 touchscreen kit that software developers that can use to develop their own.

Note that N-trig's demonstration is being performed on a tablet computer, as well as on a convertible laptop/slate. Why tablets? Aren't they just a niche? So far, yes. But that's going to change big time. There's a whole population of computer users that is simply not deskbound. It's called students, and, as we have stated in these pages again and again, the only viable computer product for students is the tablet. "Textbooks and other illustrated books simply cannot be crammed into anything smaller than a screen close to the size of a laptop," I wrote. "Tablets have all the virtues of laptops PLUS touchscreen functionality. For students, reading books on an e-reading device is highly desirable but not as imperative as the ability to handwrite notes on their device's screen."

Students will certainly give N-trig's DuoSense two thumbs up, plus the other eight digits as well. "Such touch software can handle lots of fingers hitting a screen at once rather than just relying on one or two digits, as most of today’s touch screens do," writes Vance.

In anticipation of a major push into the tablet market, Microsoft is reported to have invested $24 million in N-trig, and the forthcoming Windows 7 (look for it in 2010) "supports gestures such as pinching and fingertip scrolling,"reports Wired. "Other Windows programs, such as Paint, will also include new brushes designed for multi-touch and features such as panning across a page in Internet Explorer." But the outer limits of known touchscreen tech is Microsoft Surface's Cynergy Labs, and it's likely that Surface will dominate the field until 3D replaces it. Check out these dumfounding videos.

Microsoft's Surface is probably the direction consumers will go over the next few years, but shimmering on the distant horizon is a means of projecting action onto a screen without any contact whatever. We caught a glimpse of this with the wearable "Sixth Sense" device demonstrated at a recent TED (Technology Entertainment Design) conference. But for a mind-bending look at the state of the art of virtual, check out Project Natal by Microsoft designed for XBox 360. Stephen Spielberg, eat your heart out.

Obama Health Plan Prescribes Tablets at $50 Billion a Pop

I've been carrying the torch for Tablet PCs from my very first glimpse a decade or so ago, but like the object of a crush who's just not that into you, my passion has been unrequited. Despite a huge array of potential applications - education alone is as rich in possibilities as Alaska's fabulous El Dorado Gold Mine - developers and manufacturers have stubbornly resisted commitment to tablets. It's a big relief to find out I'm not alone, to learn in fact that I'm in such august company as Bill Gates. I urge you to read Conrad Blickstorfer's expert analysis of just why, for all its superb qualities, the "slate" (another term for tablets) has not yielded to our protestations of abiding love.

One sector of the computer-using community that has kept the embers burning, however, is the medical profession. As soon as Microsoft released the first version of Tablet PC, doctors seized on it as the answer to their prayers. At last they were liberated from the bondage of paperwork that cost them one hour of clerical duties for every hour spent attending to patients. With its portability, handwriting recognition and easy interfaceability with centralized databases, doctors could make their rounds with Tablet in hand and enter information in real time. Tablets even recognized the traditionally execrable handwriting of doctors, but e-ink and virtual keyboards have replaced the pen and all but eliminated the possibility that the computer could read "atropine" for "aspirin."

And now, with President Elect determined to create a $50 billion national computerized medical archive at the heart of his health care initiative, the tablet will at last find its place in the sun.

A microcosm of this world to come can be seen in Steve Lohr's New York Times examination of a small Wisconsin clinic that in 2003 introduced wireless tablet computers to its medical staff and required it use them. Lohr describes the many virtues of the program:

A paper record is a passive, historical document. An electronic health record can be a vibrant tool that reminds and advises doctors. It can hold information on a patient’s visits, treatments and conditions, going back years, even decades. It can be summoned with a mouse click, not hidden in a file drawer in a remote location and thus useless in medical emergencies.

Modern computerized systems have links to online information on best practices, treatment recommendations and harmful drug interactions. The potential benefits include fewer unnecessary tests, reduced medical errors and better care so patients are less likely to require costly treatment in hospitals.

The widespread adoption of electronic health records might also greatly increase evidence-based medicine. Each patient’s records add to a real-time, ever-growing database of evidence showing what works and what does not. The goal is to harness health information from individuals and populations, share it across networks, sift it and analyze it to make the practice of medicine more of a science and less an art.

You can see a typical computerized e-health patient record here.

Okay, that's one industry about to be conquered by the tablet. But I won't rest until I see one under the arm of every college student.
