2. Outline  Introduction  Previous Work  Track & Recording  Pseudocode  SQlite  Blocking  Interface  Monetization  Future Extensions

3. Introduction  CrunchTime allows users to dynamically track and block websites of their choosing in order to maximize productivity  Displays websites based on top visited sites  User-inputted preferences for blocking and tracking  Alerts user and provide dynamic blocking

4. Previous Work  Others add-ons based on this idea exist with very basic functionality:  BlockSite  PageAddict  We reproduced this, as well as add:  Dynamic Tracking

5. Tracking & Recording  Get url by site by using:  var site = window.content.location.host  Parse the string to extract the useful info  Record activity by adding multiple EventListeners to record starting time  Stop recording when user leaves the site  Stop recording when user is idle for more than 30 seconds  Continually have EventListeners track activity such as mouse clicks, scrolling, typing, etc

6. Psuedocode  On loading site  Get url (window.location.host)  Add several EventListeners to start recording  Focus, mousemove, and keydown  Enter a start recording function  Record time started  Add new EventListeners to check if user is idle  If user is idle for more than 30 seconds, pauses recording function

7. Pseudocode (Continued)  On leaving site or if user is idle, enter stop recording function  Get time again  Subtract different times to find out total time spent  Store site and time spent into array  Update total time, if site has been accessed before

8. SQlite  Store website information, time spent, and last date spent on site into an array  Store array into a “local” database using SQlite  Allow the user to store information onto the computer and to easily access later  For example, Firefox history is stored using SQlite.

9. Blocking  The block list provides a set of sites that can’t be visited  Use javascript to prevent access  If users attempt to access a site on the block list---they will be redirected away and notified  Time frames can be set when blocking is active

10. Interface  Firefox add-ons use an XML language called XUL  Uses elements from a XUL library of buttons, tabs and the like  Will be used to set preferences: add sites to block and blocking duration  Also to display ten most visited sites in the sidebar

11. Monetization Background  Competition is intense – 5848 add-ons available  Hard to monetize add-ons without losing users Potential Sources of Income  Use feedback from users to build premium version with additional features and functionality  Sell information from tracking users’ browsing activities to advertising firms  Asking for donations

12. Possible Future Extensions  Include a calendar synchronization feature  Synchronization with email, facebook, twitter and blackboard  Develop a premium version for corporate clients  Add password protection for preventing users from altering preferences
