Overview

• Dr. Jerald Block

• The study of compulsive computer use.

• Vista creates logs of game use.

• Our program– Collects this log information.– Sends it to the researcher.– Puts the information into a database.

Background - give some information about why your product

is needed• Current research data gathered is

inaccurate.• Currently data is gathered by:

– Recall– Self Diary

• Our software increases data accuracy. It is:– Automatic– Accurate to the second

Vista Game Logging• Features

– Game Logs – New Windows Parental Control(WPC) features in Vista

– Upload Game Logs – Send log file to researcher server

– IIS – Web server– ASP.NET – Server side scripting– SSL – Security– Upload.aspx – Server side script– MS Access – Database, UI, Reports

Participant Application

• Upload Game Logs– Upload file to server without user

interaction/confirmation

– WebClient object supports HTTPS – UploadFile(uri,”POST”,logFile)

Researcher Application

• Internet Information Server(IIS)– Allows remote users ability to POST

files– Firewall settings configured to allow

SSL traffic on port 443

• How to get it to work:– Default IIS installation and

configuration

Researcher Application

• ASP.NET :– Allows remote users ability to execute

server side scripts• Server side file input and output

• Database operations open, update, etc.

• How to get it to work:– Register IIS as program to use ASP.NET

– Register the aspnet_isapi.dll

Researcher Application

• SSL– Allows the ability for data to be sent

over a secure channel.

• How to get it to work:– Generate CSR from IIS– Submit CSR to certificate provider to

get a .cer file– Configure IIS to use the certificate

Researcher Application

• upload.aspx script– Archive incoming log file to server file

system

– Load data from log file into database

• How to get it to work:– Put script in web folder on server

Researcher Application

• MS Access– Database

– User Interface

– Report Generation

Product Demo

Now we are going to Demonstrate the Application

Sponsor Feedback

• Generally happy with the resulting application and its functionality– While we were unable to add all the hoped

features many of the features (easy install) were implemented

• Could have used him as a source earlier in the process– As we ran into difficulty, consulted him and

used his influence to unblock barriers

Development Process• Create The Two Core

Solutions– Build the sln file for the

researcher and participant applications

– Create stubs for planned functionality

• Begin Building Applications– Create Access Database 120

hours– Implement communication 60

hours– Update participant application

with features 60 hours– Gather WPC information to

populate database 60 hours

• Estimated hours of effort– 120 hours for the database– 60 hours for communication– 60 hours to complete

participant application– 60 hours to prepare data for

transmission to researcher• Actual effort

– 120 hours for database– 90 hours for communication– 90 hours to complete

participant application– 120 hours for data

Future Features

• Automate the uninstall process of the application– One of the few alternate features time did not

allow to be implemented

• Encode/Encrypt Data on Client Machines– Plain text data may allow undesired

functionality that might disrupt the study

Project Load Divided• Priya Pitla

– Build Database/Schema

– Create Reports

• Desiree Mijares– Build Database/Schema

– Create Reports

• Ryan Hieber– Database propagation

script

• John Van Drasek– Communication

– Client Installers

• Tony Kautz– Researcher Installers

– Report Compilation

Lessons Learned

• The use of a SVN– Thought we would not need one

– Helped to better organize our information

• Difficulty of seemingly easy tasks– Enough work-hours or personnel on particular parts

• Assume information/tools available work without verifying– Verify tools meet our needs early in the

development

Database

• Create a new study project.

• Add/remove new families and family member for studies.

• Schema

schema

Generate reports

• Subject categories for the statistic:Criteria: age (high/low), sex, start date, end date, period of time, and game hours,                                                            

• Compute Average and variance for the following Variables:1. Computer Start up time (daily)

2. Computer shut down / hibernation time (daily)

3. First game start up time (daily)

4. Last game shut down time (daily)

5. Total time gaming (daily)*

6. Total game launches (daily)*

• Cutoff time and metric time
