On a newer touchscreen device that supports multiple touch points, however, the end user may manipulate project screens and screen objects with two or more fingers at the same time. The additional touch points provide context that is not available in a single touch point; two fingers working together can perform different gestures, and different gestures trigger different actions on-screen. For example:

• You may swipe two fingers together in the same direction to quickly pan through a window or scroll through a list;
• You may stretch and pinch with two fingers to resize a screen object or zoom in/out on a project screen; or
• You may “grip” a screen object with two fingers and then rotate it like a dial.

Requirements and considerations

These requirements do not apply to the computer that you are using to develop your InduSoft Web Studio project; if you can run the development application and create a project, then you can configure the necessary settings to include multi-touch in your project.

To confirm that the client device supports multi-touch gestures, open the System control panel (Start > Control Panel > System and Security > System) and then look for Pen and Touch. It must say that touch input is available with at least two touch points.

If you will be running your project in a mixed environment — that is, if your end users will be using different types of client devices, including some that do not support touch input — then you should be careful about how you include multi-touch gestures in your project. Always provide a second way to manipulate a screen or object, using a keyboard, a mouse, or a single-finger tap.

Support for Windows Embedded Compact

Support for multi-touch gestures on Windows Embedded Compact devices is limited. The specific limitations are described in the respective sections, but the table below provides a summary.
