Efficiency: The key increase in efficiency in this design is that to take a picture and insert it into the notes, the user is not required to pull out his or her smartphone and take a picture with it (or even own one). The screenshot feature allows for quick transitions between note taking and picture inserting. The ability to seek through the recorded video by clicking on a certain section of the notes is also a huge boost in efficiency, because the user is not required to slowly seek through the video to find the relevant material. While it is faster to take a picture and integrate it into the notes in this design, it may be more difficult to get a high-quality picture of the diagram that the user wishes to insert. With a different design that allows pictures to be taken with an external device, it could be easier to get a better picture of exactly the right parts of the chalkboard or presentation.
Safety: Video editing is not going to be a focus in the development of our application, so if there is something wrong with the video or if the user wants to cut parts of it out, they might encounter difficulty. However, pictures will be easily delete-able, so an incorrect screenshot will not be hard to recover from. The notes themselves will always be editable afterwards, so any typing mistakes can be easily corrected. With the ability to watch the entire lecture again, these mistakes will be easy to spot and can be corrected more accurately than in a design that didn't include video of the entire lecture.
Design 3
In this design, we allow a single level hierarchy that lets you put notes into different categories, and the list of notes is displayed on the same page as the editor. Rather than inserting pictures from a camera, this design allows us to harness the ease of typing things on a laptop and the ease of drawing things with a touchscreen by using a smartphone to create hand-drawn diagrams, which will be inserted into notes taken using a webapp on a laptop.
