Problem Statement/Motivation

• Obesity and poor fitness is a growing epidemic in
  the US
• Most adult Americans dont achieve the 150
  minutes of recommended physical activity a week
• I believe a large problem is not knowing about
  close-by free activities that are more fun than
  traditional exercise
• E.g. A large amount of running/biking trails
  right here in Orlando that most (including
  myself) dont know about!
• This app attempts to help that, by allowing
  community contributions of local activities and
  sharing via central website map

Implementation Architecture

• System composed of servers deployed in Amazon
  cloud for displaying of site and handling
  webservices mobile smart phone clients to
  record and upload activity data

6
Client Implementation

• Written using PhoneGap framework for iOS allows
  development using HTML/Javascript/CSS and hooks
  into functionality like GPS, etc.
• Interfaces with Google Map Javascript library,
  jQuery AJAX support, and custom jQuery Dialog
  library
• PhoneGap allows for easy porting to Android etc.
  too!

7
Server Implementation

• Server code provides public facing website, and
  web services to handle authentication/data upload
• Written in PHP 5 using CakePHP framework using
  MySQL db, deployed on Amazon EC2

8
Server Implementation

• Displays map of all local activities for
  community
• Drill down detailed view of activity (speed map!)
• Personal log (after authenticating)

9
Related Work

• BikeNet from previous class presentations
• Similar in that it tracks on a map bicycle route
  and delivers real-time feedback to cyclist
• Differs in that OTF doesnt require an expensive
  custom built bicycle with sensors/helmet just
  an iPhone/Android device with GPS internet!
• Also can track many types of activities

10
Future Work

• Tie in camera to take photos of interesting
  things on the route, or of the location?
• Expand client to allow pulling in community data
  for directions to nearby activities, race against
  previous times, add comments, etc.
• Account creation is manual right now, no sign up
  flow in web
• Suggested activities shown on persona log? (i.e.
  Amazon offers?)
• Ability to edit locations using web app after
  uploading (GPS has a decent amount of error) /
  Ability to delete unwanted activities etc.

11
Demo Time!

• Data collected in my own local neighborhood of
  Celebration, FL using personal iPhone 4, and
  uploaded to a real Amazon EC2 server
