PointnTalk is a CWS developed software application that allows the user to easily create voice-overs for one or more images, optionally with synchronized pointing, and annotation marks. Once saved to an XML file (with referenced resources), the annotated images can be shared. PointnTalk versions have been created for Microsoft Windows, Android, and Web Browsers (tested with Chrome and Firefox). If a recording is about a geographic area it can also be exported as a Google Earth tour. The storage required is much less than a video file, because the static images, voice recordings, and gestures/drawings are saved separately, then re-synchronized when played. The application provides greater presence and less ambiguity in communications than other popular forms of asynchronous communication (e.g. Microsoft PowerPoint, Email, or text messaging) as users are able to process the multiple complementary communication modalities in parallel.
