1. 전체 수정
1) 수정 전
- 데이터 입력: 사용자가 직접 입력, 사전 검색 후 검색 내용 저장(문제점: 사용자 입력단이 복잡)
- 통계: 데쉬보드형 통계를 직접 보여주고 학습 방향성을 제시(문제점: 사용자 관점에서 효율성 저하 및 이탈 상승)
- 엑티비티 구조: 4개 엑티비티 전체에 무게를 부여하고 각 엑티비티 하위에 서브엑티비티까지 구성
2) 수정 후
- 홈 화면에 나머지 엑티비티 통합 정보 게시
- 데이터 입력: 사용자는 직접 입력하지 않고 무조건 사전을 검색 후 검색 내용을 저장하여 일관적인 데이터 수집
- 통계: 데쉬보드는 유지하되 설정 중 하나로 묶고 참고용으로만 제공, 홈화면에 통계를 기반으로 한 학습을 선택할 수 있도록 하는 데이터로 사용
- 엑티비티 구조: A, B입력을 통합하여 버튼으로만 구동, 메인엑티비티(통계기반 학습추천, 직전 추가 단어 20개 리사이클러뷰, 시험 숏컷, 엑티비티2(단어장 검색, 고정, 삭제 기능), 엑티비티3(OX, 매칭, 빈 칸 넣기), 엑티비티4(통계, 테마 선택, 글 꼴, 푸쉬알림 수신, 데이터 리셋, 개발자 메일)
2. AI 활용 방안
1) 통계 분석
- 통계 기반 테스크 추천: 추천 암기 단어 리스트
2) 시험 문제 생성
- 추천 리스트 기반 시험문제 생성
3) 추가 확장 가능성
- 오늘의 할 일 테스크의 유형 다양화 > 더욱 다각화 된 추천
3. 코드 정리
