+## Introduction
+
+The grand prize of the 21st World Embedded Software Competition goes to SOFI of team VOIDMIAN! SOFI stands for sound of food information and is a voice-enabled food information system for those who are visually impaired or with low vision. With the food classification and use-by date detection device, SOFI helps users with visual impairment or low vision, due to age, LASEK, etc., select food and prevents them from consuming unhealthy food. Team VOIDMIAN analyzed the space of the refrigerator's home bar from a fresh point of view and added a rotating food scanning function to the door of the home bar, and also they implemented a voice-enabled food information system based on webOS Open Source Edition (OSE).

+Let's see a demo video of the project (Korean only).

+## Features
+
+The key features of the project are as follows:
+
+### Voice command recognition
+
+- Users can scan, register, and inquire on products using voice.
+- Provides voice-enabled UI so that those who are visually impaired or with low vision can use all the functions with voice commands 
+- Buttons are also available if voice commands are not needed.
+
+### Product image scanning and data storage
+
+- Scans and registers barcodes, use-by dates, and allergy information of products using ESP32-CAM
+- Stores product information in JSON files for ease of management and platform independence of data 
+- Secures accuracy of product information by scanning multiple images 
+- Ensures accuracy in barcode recognition using the product barcode image recognition library (via Pyzbar)
+
+### Data management and inquiry
+
+- Users can inquire on the registered product and user information via web app (webOS) and mobile app (Android)
+- Outputs product and user information, which is originally text based, with voice using TTS
+- Helps determine whether to purchase products by analyzing the product information (allergies, use-by date, etc.)

+
+## Winner's Interview
+
+The SOFI was proudly awarded the grand prize recognized as an excellent example of how webOS can be used to help the visually impaired and others with low vision. 
+
+Here's what the VOIDMIAN team members feel about the whole experience in the competition.
+
+> It wasn't a difficult choice that we picked webOS when applying for the competition. We knew it is a stable operating system that had already been adapted to LG smart TVs and thought it would be a good fit for our project.
+>
+> However, despite the wide knowledge about Linux and Windows that our team has, we had to go through many difficulties as novice developers of webOS. We had to start from understanding how webOS works. While working on the project, the webOS OSE developer website helped us a lot as it provides detailed guides on how to implement web apps, use the LS2 API, and so on. Thanks to those guides, we could resolve problems one by one during the development.

+## Introduction
+
+The winner in the webOS sector of the 21st World Embedded Software Contest was team Web Oh Yes who developed the Housespital (House + Hospital) service. The Housepital service is a personalized medical service that can upgrade each individual's personal health management.
+
+With a growing number of single-person households in all age groups, the need for lifestyle-customized healthcare services is also increasing. Older people need those services as their nutrition intake and activities decrease, and young people need them because they are too busy working to care for their health. To adress this problem, the team designed a telemedicine service, a.k.a. Housepital service, for the medically vulnerable. In order to overcome the time and physical limitations to visit a hospital, they developed a real-time remote medical treatment system using webRTC and further advanced it to an all-in-one healthcare service where all related players - patients, doctors, pharmacists, and emergency rescue situation rooms - are brought together. This Housepital service aims at building a 24-7 remote medical checkup system for the medically vulnerable by sharing neceessary data, such as medication and healthcare records, with hostipals and ultimately providing a customized comprehensive healthcare service. 
+
+Let's see a demo video of the project (Korean only).

+
+## Winner's Interview
+
+The Housepital service was a good and opportune use case of webOS that builds an efficient medical examination and treatment system for both face-to-face and remote cases in an era where the number of single-person households is increasing.
+
+Let's listen to what the Web Oh Yes team members want to talk about the experience in the competition and the award.
+
+> When we first experienced webOS to compete in the webOS sector, we became fascinated by its expressive power, and while developing web apps and services using LS2API on the platform, we also found out that its development environment is very efficient. 
+> 
+> Sometimes we ran into  problems in setting and configuring the development environment in the process, but thanks to the kind and active support from the mentor in LG Electronics, we were able to fix them. We would like to take this opportunity to express our gratitude to the mentor. Although the competition is over, we are planning to organize a circle or study group to continue studying webOS and searching for ways to make use of it.
