Given our conclusions from the field study, we have brainstormed some recommendations for the next steps of our project. For our paper prototype design, it will be important to incorporate elements that users found useful. These include functions such as: rewinding, skipping, pausing, video captions, speed adjustments and visual annotations, which were all functioned noted by our study participants to be useful.
A current idea for our cognitive walkthrough is to add heuristics that account for different base levels of a user’s knowledge as well as the type of video being followed. This is because we noted different styles of interaction based on the type of video being watched. Specifically, informational videos were watched more linearly while tutorial videos had users follow along step-by-step and were watched in a non predictable order.
Our evaluation will address a user’s level of focus while interacting with a video and determine which level of video chunking is useful for allowing a user to remain engaged. This was because study participants often became disengaged when videos contained too much information or pieces of information that they felt were unrelated to their learning goals. Besides this, the foci described for our cognitive walkthrough will also be relevant to our evaluation.
