We have a customer asking for a unique function in their exams we're building in Captivate 2019. I have a few programmers thinking through what it'll take to get done. They are coming to the same question that I can't answer and wanted to ask if anyone has dealt with this idea (or a similar one) before going to Adobe Support.
We are building an exam template for the exams that accompany their online training courses. We are building it in Captivate so that we can continue to use the common variables for xAPI statement purposes. Just about all of the functionality they are looking for can be tackled with the standard interactions (bookmarking, notes, etc.), but there are a couple that are outside its standard capabilities.
They want the ability to have their students measure an object within an image file displayed in (or next to) the question. I originally expected to be creating rulers using a drag n drop interaction that would allow the student to drag them to the proper area and read the ruler, but they are looking for something that is a bit more advanced (and consequently more difficult to develop).
Starting with the display aspect, they want to have an image file be displayed that does not display entirely at once. It would be "scrollable" left-and-right with a slide bar controlling where in the image file they are looking. The student then engages the measuring tool (presumably by clicking a button), which allows them to drop a marker at Location 1, move the slide bar so they can see where the measurement should end (Location 2), click Location 2, and get a measurement in inches. (Sidenote: I recognize that the measurement output would be standardized and not correspond to what they would get measuring the area on their monitor with a ruler. We are simply looking to familiarize them with using this type of measuring tool, which is analogous to the equipment to be used in the field).
They need to be able to measure in as many directions as necessary, and then choose the correct answer (we have the question part covered, we're focused on figuring out how we provide the student the ability to get the proper measurements). And, of course, we may need a closing action to get it off the screen.
The last big picture necessity is that their students are able to see the question and answer choices alongside the measurement tool without having to click back and forth between tabs. We have preliminarily solved this by intending to create the Captivate file (and Multiple Choice Master Slide) with dimensions of about 1920 x 1080, with the question and answers on the left, and all reference materials and tools to display on the right programmed to buttons to display/close them. Ideally the image and measuring tool would be contained within the proper Fluid Box (in template attached, it's FB below the buttons on the right with the placeholder text). However, we recognize that this might not be possible and would be open to a popup window, iFrame, etc if necessary.
