3. INTRODUCTION
• Project Name
HOWELL (How well did I do?)
• Type
Personal Management
Fitbit Third-party Application
• Description
• Howell is activity analyser that how
well user’s schedule is accomplished
by real life via Fitbit activity data.
• Howell focus on specific schedule like
sleep, study and research that need
activity of hand.
(Fitbit Activity Tracker 장비를 이용한 Calendar상의 자신의 계획과 실제 생활에서
의 활동이 얼마나 잘 수행되었는지를 Dashboard식으로 보여주는 Widget
특히 수면계획과 공부/연구 등의 손을 쓰는 계획을 주로 매칭)
ACTIVITY ANALYZER
HOWELL

4. WHAT IS FITBIT?
Fitbit Products
Fitbit System

5. CURRENT PROBLEM
Fitbit Third-party Apps
• Mostly of third-party app focus on health-care, not adjust of user’s plan or daily routine
• Most of user create their daily routine using default calendar app
• If user want to set a goal, he create only through Fitbit App

6. HOW TO WORK?
1. Tracking Data Sent to App via Bluetooth
2. Activity Data Sent to Website via Wi-Fi
Third Party
Apps
★Category of Activity Data
- Walk/Running
- Sleep
- Activity
3. Third-party can access data via OAuth and API

9. SYSTEM ARCHITECTURE(CONT’)
HOWELL
• 백앤드를 위한 것이 많음.
• HOWELL은 백앤드를 통하지 않아도 된다고 생각함.
(Howell - Google App Engine System)

10. OAUTH 인증
http://oauth.net

11. UI
• Main
• 상단 : fitbit 로그인 화면
• 중간 : 수면 분석화면
• 하단 : Calendar Pickup

12. UI PROTOTYPE
• Fitbit Login
• 유저가 기존 세팅해둔 계정으로 Fitbit 로그
인 후, 권한 설정할 수 있음.

13. PROBLEMS
• Google Calendar Provider
• 캘린더 데이터를 UTC millis로 주어서 형변환에 문
제
• Content Provider를 사용하기 위해, 쿼리형식을 사
용해야 함.
• OAuth 방식의 문제
• 최초 Back-end를 사용한 OAuth를 사용하다 속도
문제로 자바스크립트와 WebView를 시도하다 결국
oauth.io를 사용.(최적화&형식화된 WebView방식)
• 안드로이드 4.2에서는 Material Design이 안됨
