- Search algorithm.
Both the main page and the search page contains the search bar. It is aimed on searching within the list of techniques/pictures/artists to find an appropriate technique. The search was implemented in JavaScript. When the user tries to search for a certain phrase, the search script reads the list of techniques and files with their descriptions and outputs the techniques which has the search phrase in their description. The search itself was implemented as a substring comparison. - Image processing for giving feedback to the user.
We used a standard JavaScript library for working with video and JSFeat (JavaScript Image Processing Library) for analyzing the user's progress and giving feedback. We spent a decent amount of time adding that library as well as programming image processing algorithms. This time spending might have affected our implementation of other parts. - Content.
The main idea of our project is to allow users to learn new techniques by redrawing pictures/paintings. That is why it is essential to have content to redraw. We implemented the techniques storage in a structured way, so that the process of adding a new technique will take only a couple of minutes. After adding a technique, the search script will take it into account and show it in the search results during the next search attempt. At the same time the process of adding techniques is monotonous and we decided not to waste too much time on adding techniques, their descriptions, pictures, etc. That is why we have 3 techniques, each has 9 pictures as levels of difficulty. So, the search script and the search page work for 3 techniques and 27 pictures. When the user wants to redraw a picture, he needs to watch a video on how the process of getting feedback works (it was a user feedback to include a video). We recorded one video for one picture, so the user can redraw one picture now. Again, we decided to record only one video in order to save time on doing monotonous work and to spend it on improving the prototype.
