This video is an example of an EPUB with embedded interactive elements running on an iPad in iBooks. There is no audio. A written description is provided. Created March, 2016.
Description: This is an example from the EPUB book Learn SVG Interactively by Jay Nick. On the left hand side of the screen we see a red circle in a cartesian plane. On the right hand side there are slider controls to change the position of the circle and its radius. As I make changes to the sliders the circle is dynamically updated. When I adjust the radius slider to the left the value decreases and the circle gets smaller. Adjusting the x slider to right makes the value larger and moves the circle to the right. Adjusting the y slider to the left makes the y value smaller and moves the circle to the left on the Cartesian plane.
