A few weeks ago, I published an article about the idea of “smart bezels” in iOS devices to avoid conflicts with third-party applications using multitouch gestures. With Apple playing around with the concept of “multitasking gestures” in the latest iOS 4.3 betas, it has become an issue for developers to find a way to enable 3,4 or 5 finger gestures without interfering with Apple’s own implementation:
The problem with the new gestures is that Apple decided to make them system-wide, activated with a preference panel in the Settings app. Once gestures are enabled, they override any other four or five finger gesture developers may have implemented in applications. Personally, in fact, I have experienced issues trying to use multi-touch gestures in Edovia’s Screens or other piano apps — software that makes extensive use of gestures above two and three fingers. Apple’s implementation overrides options set by developers, and there is no way to let the iPad know whether a user wants to perform an app-specific gesture or a system one, like “open the multitasking tray”.
