Multi-Touch Human Interfaces Have Arrived

Multi-touch human interfaces have arrived, but until now they have a surprise visitor: We will be happy to see them, but we are not willing to let them move in for good. For those of us who are engineers and are working every day to realize the dreams of future products, multi-touch offers an opportunity to change the world, in much the same way, the first graphical user interface učinio.Utrka just begun, but do not make a mistake, it will soon be won. Personally, I am not convinced that we have a winner, but if you do not step up to make a multi-touch technology, great, we'll live with it as a border for a long time.

The multi-touch?

of the world applauded Apple's first generation of the interpretation of multi-touch interface in the iPhone 1.0. The new user interface is the radio, it offers the right functionality, but did not forget that the phone-call easily. Apple iPhone is the added gesture of our vocabulary, offering two-finger pinch to zoom-in, opened with two fingers to zoom-out and two fingers to rotate, as intuitive and useful to the device with a camera and small screen

Multi-touch technology, today

Unlike a single-touch interfaces are often based on the old "touch screen" technology most of us experienced on our cell phones and PDAs are resistive, where the pen position yielded two voltages, one is the "X-axis" , the position and the other is a "Y-axis". One-touch interfaces result in the same XY data that traditional song and mouse pad offers today. For its multi-touch interface, Apple uses a capacitive sensor and Microsoft Surface uses cameras. Capacitive sensing technology is commonly used in a touch trackpads in laptops. There are several modules, display and individual silicon vendors to support multi-touch, so many options available in the market, choosing the potentially confusing process. Depending on the technology, it is possible to sense the position of all 10 fingers on the screen. Certainly the ability to support multi-touch interface in many ways is dostupna.Trljati that there is no one standard way to use this multi-touch data in computer applications.

to see where the multi-touch can go back to the two easiest to see the implementation of multi-touch to interpret what users of the future (to you and me) trebaju.Apple iPhone conducts what is called "Multi-Touch gestures ", where the two fingers felt their relative proposals translated into gestures that can react to the program (ie, rotate, zoom, and pan). At minimum, these gestures need to appear quickly in the lexicon of each laptop, but it means that each program and the operating system needs to change to accommodate them. Besides the 2-finger gestures, images, blurring fast. "Multi-touch all point" technology allows many simultaneous inputs from the touch screen or touchpad. What to do with this entry, now is the question. There are great opportunities here, but the current example of Apple and Microsoft did not exploit them to the fullest.

Apple has included three four finger gestures on the new MacBook, but only Apple applications use these gestures

(as opposed to scrolling and clicking to the left two-finger gestures). In addition, the thought process behind that function should take three fingers and four fingers, which seems to be somewhat arbitrary. What does make sense is the return of a button, is used as a modifier to the three-finger gestures, although the touchpad is large and has the ability to feel a lot of fingers. Also, multi-touch equivalent + click-drag the selection seems to have disappeared. Anyone else have a problem with adopting a fully Palm (TM) PDA for graphite (TM) has never become second nature?

intuitive gestures as easily adopt

Also, the surface of Microsoft (TM) appears to be a cornerstone in the dark when it comes to using more than two fingers. For example, they are virtual air hockey game demo that uses one finger for each player to grab and move the controller (there is another version that uses the physical controller as a traditional air hockey table, but it is not multi-touch interface) . When I play a real air hockey, I'd be stupid to use one finger, a true-to-life nature of the surface does not reflect the behavior as you can see the user controller slip-and-slide around as if it were using only one finger to control the large disk . There are other problems too, such as controllers sometimes switch players when they get too close. This comment does not intend to slam Apple's MacBook and Microsoft Surface, but emphasized the fact that the multitouch field around otvorena.Tehničke opportunities available today do not offer much more natural and intuitive user interface if and only if we as engineers harness the power and direct the greater good.

for software development kits and software development tools for Microsoft, Apple and Linux all provide built-in support for standard keyboard and XY shows devices (mouse and monitor, pad buttons as well). Everyone is now able to target any operating system as long as the "input" is translated into one or more keyboard keys and XY position, any application can use input. For example, someone might develop, using the standard offer in any operating system, 10'-by-10 'room as track replacement, where the water around on the floor, jumps up and down and throwing his body against the wall selection and move the icons around your PC screen. The multi-touch the future, we as a development community needs to be done to ensure a similar level of freedom to develop devices and applications that interact with them? What do I look like a standard set of features and provides program developers do not have to worry about input and input decisions do not have to worry about programs? Although definitive answers to all of us, the answers are still evolving and could seriously affect our lives in the future.

Future Multi-touch is in our hands

"Standards" for the multi-touch interface to grow whether we like it or not, and now it's time to get involved, make noise, showing shape the future of multi-touch. Let me put forward some of my suggestions for a better future multi-touch. Read them, use them to come up with better ideas, then join it to work with standard setters and the implementation of multi-touch device and putting it in the hands of people so that we can mobilize more troops to fight for a large Multi-Touch future.First, we need some standard, intuitive gestures and other, we need a standard interface data to provide information about the position and up to 10 fingers. Standard gestures should cover the most common computer / information on business devices, such as scroll, zoom, select, move, and grab-and-move, as well as all the new features Multi-Touch will allow. What we should be more companies asks a patented movement. Instead, some innovators patent better and smarter techniques of determining gestures. Keep in mind that we do not need a long list of standard gestures, as if this is what we get, users will need to print the list and paste it back on their device, as we all did the graffiti on our Palm PDA before we ceased to use them. Also, the gesture detection can not be forced only on the operating system, or can be forced only to unos.Najbolji standard solution to fit and maximum flexibility. However, if the choice between

operating system or a forced entry, the operating system must be allowed to win.

Do not stop with the standard gestures (or consequences: Not defined as any gesture). Define data standards for multitouch input devices for monitoring up to ten independent inputs. Understand that the use of this information for quite some time to be application specific. That said, the best behavior over time (hopefully) will be adopted in operating systems, why ten and not more? Most devices are primarily a single user or multiple users to easily act on a relatively small screen. Some special-purpose large-format devices such as surface to investigate what to do with more than ten inputs, and when something proves itself useful, it can seep dolje.Multi-Touch train leaves the station. For those who do not like what they have seen so far, get involved and push the envelope further. Use multi-touch in new and interesting ways, and allow others to see and hear about their successes and failures (especially the guys in Cupertino and Redmond). The industry can make a super multi-touch, but only if we do

together.
