Easy Logging

How happy are you?

We could measure:

Attention

Emotion

Fun

Bio Feedback

EEG & EMG

Galvanic skin response

Gaze tracking

But there is one Problem…

Integrated logging is:

Limited

Complex

Impossible**sometimes

Focus on data analysis, not implementation!

So how do we simplify the integration of logging?

By providing a Logging

Framework!

Design & Structure

Constraints

Benefits

Verification

What is this Framework?

Design&

Structure

We want to…

Develop stimulus games

Access specialized hardware

Write log files

…as fast and easy as possible!

Technology that helps:

C# .NET

XNA

Torque X

Data acquisition Hardware

Logging Components

Log Files Database

Torque XGame

How is it structured?

So all is perfect?

Constraints

Some programming is still required…

The game will not* look like this!

*probably

The game will look more like this.

Benefits

It allows iterative development!

It encourages prototyping!

It is highly extensible!

It is a tool to innovate game

interaction!

Games with gaze-based interaction!

Games with automated data

collection!

Games like Blob!

Verification

Blob in a Nutshell

Collect as many blobs as possible

Blob in a Nutshell

Bigger blobs =

higher score

Blob in a Nutshell

Blobs collide = game over

What is logged?

Player performance

Objects in gaze focus

Game events

Blob allows us to

Compare interaction modes

Investigate visual attention

Build better games*

* In the future

All because of the Logging Framework!

Three things to remember:

Logging and analyzing psychophysiological

data helps us to understand players.

Three things to remember:

Implementing

integrated logging is complicated and time-consuming.

Three things to remember:

The Logging Framework

provides proven and tested logging that is

easily integrated.

Thank You!
