Asterpix allows the user to upload video and create hotspots that follow an object or person on the video. The user can mouse-over the hotspots and click for more information: text, weblinks, etc. (Hence the "interactive" part.) The tools seem very easy to use, and the instructional videos are screencasts, as illustrated here.
This tool might work very well with an EFL/ESL practice where the students are led to research further information (a mini-Webquest), or are asked to create their own video and links for the hotspots. This is another tool with a unique twist that can add text and hypertext to the audio-video experience.
Thanks to Andreas Büsing for the tip on this item.
