Who says JQuery Mobile is touch optimized (
QuoteYourSources)? Putting the question in context will help with the answer.
In general, touch optimized in terms of a framework would mean:
- It can detect and track multiple touching points on the screen
- It can provide that information to applications using the framework
- If it has UI elements, those elements would be scaleable to different resolutions
- It would support or provide navigation schemes that are easy to discover with finger touches and don't rely on precision pointing (again, assuming UI components)
