Application Development

OnScreen applications are produced in the Tumult Hype system which is included with OnScreen.
Each new application begins with all the functionality of OnScreen ready to go.

Sample Screen - in development mode


Screen elements shown: - (from left to right)

Screen list. Each screen, shown in miniature, may be moved, renamed, deleted, or selected to edit its content. New screens are created by duplicating an existing screen.

Table of Contents. During development, the Table of Contents is shown blank in the standard layout, or may be removed from any screen to exploit the entire screen width.

Main content area. The developer keys in and formats text in this area, and drags in and scales images. Whatever the developer sees here is what will be seen when the application is presented.

Content editors. Used to format text, create links to other screens, create vector drawings, and define text pop-ups. Here, the Text editor (T) is shown selected.


OnScreen was designed with both the content developer and the end-user in mind,
drastically reducing the time and effort to produce engaging and memorable content.
