Group Assignment

Compare as many tool options as possible

We explored different languages, interfaces, and applications that can be used for creating user interface that can be visualizing sensor inputs. One of the interesting platform was Glitch, that allowed hosting server on different devices an can also easily integrate AR on the web. I tried to use Glitch to do some AR, as using some bar codes or QR codes seemed very interesting! I didn't end up doing another related project, as these were not going to be related to my final project. But I think it's a very interesting platform to explore further!

Individual Assignment

Write an application that interfaces a user with an input &/or output device that you made

I developed an application specifically for my final project. The primary goal was to create a web app that allows users to log in and track the ingredients they want to buy. To integrate it with a touchscreen monitor as an output device, I uploaded the website to a global server, making it accessible through the touchscreen. Users could interact with the touchscreen to add or delete ingredients, and the updated list was saved on the webpage or a phone, allowing access from anywhere. Some technical challenges I addressed included saving data locally and enabling the ingredient list to be read aloud, either automatically upon page reload or manually by pressing a button.

I also created website tracker that will in real-time be synced with list.html so that users can keep log.

For this week, I initially decided to host the website on a Raspberry Pi. However, the speaker did not work, and I identified that the issue was with the audio library not being supported by Chromium. While I paused progress on the audio integration for this week, I came back to this week and added a proximity sensor so that the display turned on and read the ingredients aloud when someone was nearby. I also bought a TFT Module to work with for my final project! Below is an image of how I was finally able to retrieve information from the website in real-time and present it on the website. Using JSON parse helped me get the exact information I wanted to be displayed on the display! When I tried to switch to XIAO ESP32, the I2S library wouldn't work (it only worked with RP2040). I decided to first focus on the display and functionalities rather than focusing on the audio.
