AI 심리 분석 프로그램 도담이

[ "SW 중심대학 디지털 경진대회 : SW 부문 ]

 

같은 연구실 사람들과 "SW 중심대학 디지털 경진대회 : SW 부문" 대회에 나가기 위해 AI 심리 분석 프로그램 도담이를 만들게 되었다. 먼저 예선 통과하기 위해서 주제를 정하고, 어떻게 생성AI를 사용할지, 어떤 어플리케이션을 만들지에 대한 회의를 했다.

 

팀원은 총 4명이며, 역할은 3가지(로고 디자인 및 PPT 작성 - 1명, 인공지능 - 2명, 어플리케이션 제작 - 1명)로 분류했다.

나는 그 중 어플리케이션 제작을 맡았다.

 

안드로이드 스튜디오 앱을 제작하면서 내가 가장 흥미를 느끼는 부분은 UI를 디자일 할 때이다. 내가 원하는 디자인으로 어플을 제작할 수 있고, 직관적으로 보이는 부분이기 때문에 더 흥미를 느끼는 것 같다. 그리고 새로운 앱을 만들 때 가장 먼저 하는 작업이기에 새로운 작업이라는 마음에 더 흥미를 느끼는 것일 수도 있다.

 

먼저 심리 상담 프로그램을 찾는 사람은 심리적으로 건강한 사람보다는 힘든 사람이 더 많이 사용할 것이라고 생각했기에 상담과 어울리는 따듯한 색인 노랑색을 메인 색상으로 잡고 디자인했다.

 

어플을 시작하면 도담이(어플이름) 로고가 먼저 나오고, 사용자의 나이와 성별을 입력하도록 만들었다. 그 후에는 사용할 테스트인  HTP 상담 설명이 나오도록 했고,  사용자가 직접 그린 집, 나무, 사람 그림을 첨부할 수 있도록 만들었으며, 그 이후로는 AI가 사용자가 첨부한 그림을 해석해서 사용자의 심리 상담 결과를 보여주도록 앱을 제작했다.

 

특히 사용자가 직접 그린 집, 나무, 사람 그림을 첨부하는 기능을 만드는 것을 내가 앱을 제작하면서 처음해보는 부분이였기 때문에 새로운 기능을 추가하고 배우는 것이 너무 흥미롭고 재미있었다. 새로운 기능을 배울 때 코드에 오류가 많이 생길까 걱정을 많이 했지만, 큰 오류 없이 어플에 이미지를 첨부하는 기능을 추구할 수 있어서 너무 만족스러웠고, 코드 작성에 더욱 자신감이 생겼다. 

 

처음으로 대회에 나갔는데 학교에서 진행되는 예선에서 1등을 했기에 뿌듯하고 코딩에 대한 흥미가 더 생겼다. 본선에 진출했을 때는 순위권에 들지는 못해 아쉬웠지만 더 열심히 공부해서 다음에 또 대회에 나가게 되면 더 좋은 결과를 만들어봐야겠다는 다짐을 했다.  대회기간동안 팀원들과 큰 트러블 없이 커뮤니케이션하며 같은 목표를 위해서 어플을 제작할 수 있어서 좋았다.
