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.

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.
