When you think about the future of clinical computing, what images come to mind? In five or ten years, will we still be using desktop PCs, computers on wheels, laptops and Tablet PCs? Will the keyboard and mouse be as prevalent as they are today? What kinds of devices and interfaces will clinical staff be using? How will device and workflow changes impact the design of our healthcare facilities of tomorrow?
Designers, architects and engineers of healthcare facilities must always be thinking about the future. So too, must the executives, managers and staff of our hospitals and clinics. It is far too easy to imagine the future as we experience the world today. But that may lead us totally in the wrong direction. Over the span of my own career, I’ve noted monumental changes in business communication and collaboration; from telephone “while you were out” memos stacked on my desk after lunch to instant messaging, e-mail, voice mail, and web conferencing that keeps me continuously connected no matter where I am.
Medical computing stated out much as computing did in other industries, with desktop workstations strategically placed around the hospital ward. As laptops gained in popularity, they were mounted on carts with wheels to improve workforce mobility and provide for longer battery life. Tablet PCs became popular particularly as new models designed specifically for the healthcare industry became available. More recently, some manufacturers have combined the best attributes of Tablets and Desktops into a new generation of “computers on wheels“. But what can we expect in the future?
I believe clinical computing may look quite differently than it does today. I think we’ll see a transition to much larger displays that take advantage of touch and multi-touch navigation married to increasingly sophisticated speech recognition solutions for data input. If you’ve seen any of our “future vision” videos, you’ll note that large screen displays with touch screens are quite prevalent in the scenarios we paint. So too are smaller, pocket-sized devices that communicate wirelessly with their larger-screen cousins whenever more screen real estate is required by the user.
You might have had a premonition of this future vision the first time you saw Microsoft Surface, or dare I say, the first time you played with an iPhone. With the launch of Windows 7, you’ll see more and more software applications and computer screens that take advantage of “touch” as a user interface. With Windows 7, if you've got a touch-screen monitor, you can just touch your computer screen for a more direct and natural way to work. Use your fingers to scroll, resize windows, play media, and pan and zoom. Windows 7 also introduces support for new multi-touch technology, so you can control what happens on the screen with more than one finger. For example, you can zoom in on an image by moving two fingers closer together, like you're pinching something, or zoom out by moving two fingers apart. You can rotate an image on the screen by rotating one finger around another, and can right-click by holding one finger on your target and tapping the screen with a second finger.
Now imagine all of that combined in an environment that allows you to move seamlessly from one device to another and being “recognized” by each device as you approach it. Perhaps you’ll be wearing a small Bluetooth enabled, bone conducting microphone. You will touch items on the screen, gesture with your hand, or use your voice to open and close windows. You will ask questions or give directions and the computer will respond. You will use natural hand gestures or touches to navigate and move from one workflow to another. You’ll transition from a large screen display to a portable device in your pocket to another large screen on the wall and pick up your work exactly where you left off each time along the way.
I believe this is the future of clinical computing. In fact, I think we are already seeing this natural evolution in the products and solutions that are hitting the market and certainly in those that will shortly be coming to market.
