This week, our team started to build the mechanical part of our system. Currently, we finished the basic skeleton of the system to hold the board and upper linear slides. However, due to the fact that the NEMA 23 motor we received doesn’t match its specification, we could not fit the NEMA 23 motor in our system unfortunately. Therefore, we will start with incorporating the NEMA 17 motor we used before this Sunday and wait for any reply from the supplier.
Individually, I spent the majority of my time working on refining the user interface of the web application and adding functionalities to enhance the user experience. I have updated the CSS of our web application incorporated some responsive design and implemented the home and logout functionalities and button as the content of a dropdown box located at the navigation bar. Moreover, for the create/modify class form page, I have changed the integer field of width to a choice field for users to select which preconfigured board the class will use since this is more intuitive for users (and typically the instructors will not use their own board while lecturing), and I changed the clean function of the form to validate whether the student IDs input by instructors are valid and raise a form validation error if one of them is not.
Regarding testing, since I’m responsible for the camera, I have completed the camera latency test by writing javascript to measure the time taken between a user clicking the “erasing board“ button and the picture getting posted to the website 5 times and taking an average. The time averages to 1.3s and meets the metric (3s) we set for the user case requirement.
I also finished the script for the usability testing of our website. Therefore, according to our schedule, my progress is on schedule.
Next week, our group will finish building the mechanical attachment and start working on the final presentation and report together. I also plan to recruit some participants to participate in the usability testing of the web application and improve our website based on their feedback. If I have extra time, I will also spend some time investigating how to the web application with Canvas so instructors do not need to manually enter the student ID (which is a post-mvp goal).
