Test Group/Test Category

1121—Browser Compatibility/Internet Explorer 11

Severity

Warning

Background

In Windows Internet Explorer 11 and Microsoft Edge, Microsoft does not support feature detection to determine if the device supports touch screens. In the latest Windows Internet Explorer browser, the property msMaxTouchPoints returns the maximum number of touch points supported, but in Internet Explorer 11 and Microsoft Edge, this property always returns undefined.

Resolution

The web application should be re-engineered so that it does not use the msMaxTouchPoints property.
