Personal Accomplishment<\/b><\/h6>\n

Other than completing the design review report with my teammates, I also worked on a couple of tasks.<\/span><\/p>\n

1. Voice Synthesizer Script<\/strong><\/p>\n

To assist Shiyi with developing an accessible UI, I created a voice synthesizer script using the open source library Google Text-to-Speech (gTTS). The script allows the user to synthesize any English text from both an input prompt and the command line:<\/span><\/p>\n

2. Database and customer-side model for orders, items, and the menu<\/strong><\/p>\n

I finalized the representations of orders, items, and the menu both on the cloud database and in local storage:<\/span><\/p>\n

\"\"<\/p>\n

The design review report goes into detail about the model and how they interact with each other, so I won\u2019t repeat them here. The important thing to note is that, by design, the local copy won\u2019t be uploaded to the cloud until the customer finishes ordering by calling checkout().<\/span><\/p>\n

I have tested the flow and successfully added sample orders into the cloud database:<\/span><\/p>\n

\"\"<\/p>\n

3. Staff-side model for orders<\/strong><\/p>\n

I designed a model to represent orders for the staff-side as well:<\/span><\/p>\n

\"\"<\/p>\n

This object will automatically be generated when a subscriber to the Redis pub\/sub channel receives a new orderNum. It allows the staff to view order items, cross out prepared items (using finishItem()), and remove completed orders from the cloud database (using removeOrder()).<\/span><\/p>\n

4. Redis pub\/sub and fetching orders from the database<\/strong><\/p>\n

The Redis pub\/sub channel is shared by the customer-side modules (publishers) and the staff-side modules (subscribers). Once the customer-side order publishes its orderNum, the staff-side subscriber thread will receive a message containing the orderNum and spawn a child thread to fetch that orderNum\u2019s information from the database.<\/span><\/p>\n

I have implemented this functionality as well, but it still requires more testing.<\/span><\/p>\n

About Schedule<\/b><\/h6>\n

Since all of us are slightly behind, the database and NLP integration hasn\u2019t been able to happen, yet. I am fairly confident that the database component is complete functionality-wise, and unit-testing has been conducted. Therefore, once we meet again next week, Lisa and I will be able to start utilizing the database with data from the NLP module.<\/span><\/p>\n

Plans for Next Week<\/b><\/h6>\n

Our microphone and infrared sensor are set to arrive next week. Therefore, I will shift gears and start programming the microphone against our RPi 4.<\/span><\/p>\n

Lisa and I will also try to integrate our NLP modules and database modules during the mandatory lab meetings.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
