I used to use Flash (Adobe Captivate) for creating CBT testing and tracking to a DB, but iPad tablet doesn't support flash, so I need to find a different technology. I also need to support older browsers like IE8 and am concerned about HTML5.
You can use Captivate 8. Best mode for what it sounds like you want is the Responsive Projects (which is not a powerpoint conversion). It publishes in html 5 and runs on iPads and other mobile devices. Seems to be several problems with Android devices, but translation to iPads for simple stuff is pretty sleek. SWF output is still an option with Cap 8, but it won't run on tablets.
Warning - it is new technology and seems to have some bugs, especially with video on the iPad. Firefox on the iPad has problems, maybe Chrome too. Personally I miss the design once, deploy everywhere days that we had with Flash.
