Unresponsive gestures occur when a user touches an element that is not designed to be interactive, resulting in no response from the app. This often happens due to suboptimal UI design, where users expect certain interactions to work but they do not.

For instance, a user might try to zoom in on a picture by pinching, or attempt to click an image that appears to be a button, only to find it unresponsive. These failed attempts can lead to frustration. Heatmaps of unresponsive gestures can help identify these issues by showing which non-interactive elements are getting attention. You can use these heatmaps to pinpoint and improve areas of your UI where users are expecting functionality that isn't there.
