Getting Multi-Touch on the TouchPad to Windows 7 –

By Yochay Kiriaty August This article is based on a prerelease version of Windows 7. Details are subject to change. This is the third article in a series of articles about Windows 7. The series focuses on new user experiences that developers can tap into to make their applications shine on Windows 7.

Part 1 covered Libraries. Part 2 covered Taskbar APIs. Part 3 covers multitouch capabilities in Windows 7. Download Windows 7 Release Candidate now to help you get the most out of this article. In Windows 7we have enriched the Windows experience with touch, making touch a first-class citizen as another way to interact with your PC alongside the mouse and keyboard.

In recent years, we have witnessed a wide range of multitouch devices that have generated an extremely positive user experience. Therefore, it is only natural for Windows to introduce such multitouch support in Windows 7 as a core capability.

With the Windows 7 Multitouch Platform, you have the freedom to directly interact with your computer. For example, you are able to reach out and slowly scroll through your pictures directly from Windows Explorer, or flick and move through them quickly. There is no special Windows Explorer that is available only on multitouch devices. The simplest example is the Windows 7 Taskbar Jump Lists.

When you use the mouse to right-click on any icon on the Taskbar, you see its corresponding Jump List. But how can you right-click using multitouch?

Simply touch the Live Messenger icon and drag out with your finger, as shown in Figure 1. As you can see in Figure 2 , the touch-triggered Jump List displays the same content as in the standard right-click Jump List. The spacing between each item in the multitouch-enabled Jump List is larger than the spacing between each item in the left image, which is the default right-click Jump List.

To provide well-rounded Windows Touch solutions for all kind of applications, the Windows Touch Platform provides various levels of support.

There are several scenarios by which you can enhance applications using the Windows Touch Platform features. Before you adopt a specific approach, you should consider what exactly you want to do with your application. You might ask yourself, what will be my users multitouch experience when running the application on a Windows 7 multitouch-enabled computer? The good news is that the Windows 7 Multitouch Platform provides a free out-of-the-box experience for applications that are touch-unaware and were not designed to support multitouch.

Specifically, it provides free, out-of-the-box support for a few basic gestures. In other words, you can expect a few basic gestures to work and to have the desired effect in your application. Basic gestures include single finger or two fingers panning, two fingers zoom, and flick gestures that were introduced in the Windows Vista time frame.

Adding Basic Multitouch SupportHere we focus on adding direct gestures support, as well as other behavior, and user interface changes to make applications more touch-friendly beyond simple gesture support.

By using the getMessageExtraInfo method, the Taskbar can trace the origin of the input message and determine whether it is a touch message and then respond accordingly. In addition, you can use gestures to enhance your application and provide better multitouch support. Applications that directly respond to gestures have full control over how they behave when a user is touching the touch-enabled device. For example, Windows 7 ships with the Windows Photo Viewer.

In the Photo Viewer application, the viewer receives specific information about the location that the zoom gesture originates from. That is, the zoom gesture contains information about the center point–specific X and Y coordinates–of the zoom gesture, and then the Photo Viewer can focus around the center of the gesture.

The Windows Photo Viewer application also uses panning and rotation gestures to provide a very good image viewing experience, with relatively little effort. With gestures, you can also override the default panning behavior. For example, the default touch scrolling is designed to work in text-centric windows that scroll primarily vertically, like Web pages or documents; dragging horizontally does text selection rather than scrolling.

In most applications, this works just fine. But what if your application actually needs to support horizontal scrolling? Also, for some applications the default scroll can appear chunky, going too fast or too slow. Experience Optimized for MultitouchThe best-case scenario is when applications are designed from the ground up to support multitouch.

This message provides raw touch data to the application, and you can consume these messages and handle multiple touch points. The Windows 7 Multitouch Platform also provides manipulation and inertia processors to help you interpret the touch messages.

Think of manipulation as a black-box that receives as input the object that is being touched and all the related touch messages. The result is a 2D affine transform matrix representing the transformation that happened as a result of the finger movement. For instance, if you were writing a photo-editing application, you could grab two photos at the same time using however many fingers you wanted to rotate, resize, and translate the photos, and the manipulation process provides the changes you need to reflect on the object.

Inertia provides a very basic physics model for applications and provides you with an easy way to continue the smooth transition of an object even after you picked up your fingers from the touch- sensitive device, to create a simple transition effect rather than stopping the object on the spot.

This is the free out-of-the-box behavior, and you will need to opt-out if you wish to stop receiving such messages. Gestures are considered as one or two fingers touch inputs that translate into some kind of predefined action gesture that the user performs. Once detected the OS is doing all the work for you , the OS will send a gesture message to your application.

This message contains all the information needed for decoding and making it work. Windows 7 support the following gestures:. Therefore, in order to determine which gesture you need to handle, first you need to decode the gesture message. The information about gestures is found in the lParam parameter, and you need to use a special function, GetGestureInfo, to decode the gesture message, as shown in the following code snippet.

With this knowledge, we can now move forward and write the complete switch-case method that handles all gestures, as shown in Figure 3. Please note that at the end of the function we call the CloseGestureInfoHandle function that closes resources associated with the gesture information handler.

Failure to do so may result in memory leaks. Handling gesture messages has a fixed flow that includes configuration, decoding the gesture message, and handling the specific gestures according to your application needs. As you can see in the preceding code, it is not that difficult to do so.

The zoom gesture allows you to scale the size of your objects. Figure 4 illustrates how the zoom gesture works. The gesture info-structure includes the dwFlags member that is used to determine the state of the gesture and can include any of the following values:. For zoom gesture, the ptsLocation indicates the center of the zoom. The following zoom message that arrives is handled by the default case. Next, we calculate the zoom center point, the zoom, and last we update rectangular our graphic object to reflect the zoom center point and zooming ratio.

Figure 5 showcases these arguments. In the default case handler, we save the location of the gesture, and from the two sets of points representing the current touch point and the previous one we calculate the zoom center location and store it in ptZoomCenter. We also calculate the zoom factor by calculating the ratio between the two points. A call to the ProcessZoom helper function updates the new coordinates to reflect the zoom factor and center point. Handling the rest of the Windows 7 default gestures is very similar to the specific zoom gesture handling described above.

All gestures follow the same flow, and just the internal logical implementation differs per gesture, per use-case scenario.

Next, we review the optimal model and dive into the API that allows you to receive and handle raw touch events. Calling this function registers a single hWnd element usually a window as being touch-enabled. Next, we iterate through the touch points array, applying our logic to each touch point, the handle ti[i] comment.

Failing to do so will result in memory leaks. It is important to note that the X and Y coordinates are in hundredths of a pixel of physical screen coordinates i. This extra-fine resolution promotes high precision and accurate handwrite recognition for other applications that may require such fine resolution.

But for most scenarios, you need to remember to divide the touch point X and Y coordinates by a hundred to translate the touch point coordinates to usable screen coordinates before you start using these coordinates. Tracking Touch Point IDsTo create the Scratch Pad application, you need to track each touch point movement and the path that it forms, and then paint a line along that path.

To distinguish between the different touch points and to make sure you really handle each touch point correctly, we assign different color to each touch point. After unpacking the touch message into an array of touch input structures, ti , you need to check each touch point state and apply different logic per touch state. You register the new touch point ID and assign it a color. For each move message, you add a new point to the existing line and paint the new segment of the line.

The key for tracking individual touch points is using the dwID that remains the same through the duration of specific touch stroke. This line is the path form when you drag your finger across the touch-sensitive device.

We are not going to cover the entire code sample that supports the application and actually paints the lines to the screen. Basically, all that you need to do in order to support multitouch can be found in the preceding code sample. The Windows 7 Multitouch Platform is a very powerful development platform. From implementing the default gesture support to the more advanced raw touch messages, it gives you a lot of power with relatively simple implementation.

The platform also includes manipulation and inertia processors. Manipulations are similar to gestures in a lot of ways, but they are a lot more powerful. Manipulations are used to simplify transformation operations on any given number of objects.

You can perform a combination of specific component gestures such as rotate, zoom, and scale on a specific object at the same time. Once the last touch point is pulled up, you may want to apply simple physics to the object so it smoothly comes to a halt, rather than it abruptly stopping on the spot.
