Cooking Assistant Application on Smartwatch

The goal of this contest is to develop an application for a smartwatch. Our team has developed a cooking assistant application that allows users to view cooking recipes using gestures without using their hands while cooking. We have also implemented a smartphone application that synchronizes with the smartwatch screen. My role was to develop a simple server that responds to recipes and implement the user interface for the smartwatch application. Additionally, I defined the messages and synchronization protocols required for synchronizing the screens between the two applications.

The server was implemented using the Express framework in Node.js, and MongoDB was used as the database. The smartwatch was developed using web languages with Tizen OS, and it communicated with the smartphone via Bluetooth.

At the time, I was interested in REST and class abstraction, and I implemented the system according to these design principles. On the day of the contest, the Wi-Fi connection was unstable, possibly due to the numerous communication devices in the area. The server connection was abstracted by the Client class, and the location of the resources was hierarchically represented according to REST. With only 30 minutes left before the start of the contest, I quickly implemented the Client class based on the file system and was able to successfully complete the demonstration. Of course, if I were to implement it again, I would have cached the recipe data, so the unstable server connection would not have been a problem.
