Presentation at the Games For Health 2012 Conference in Boston -
The presentation outlines the development process of a cognitive training and assessment, highlighting the need to facilitate communication between developer and clnician by building a flexible application framework. In such framework it is of highest importance to be able to change tasks, content, timings, interface and instructions rapidly to adapt to different patient populations. For questions about this presentaton please contact Sebastian Koenig at koenig@assessim.com

3. Overview
• Cognitive Assessment
• Ecological Validity
• A Framework for Cognitive Assessment
• AssesSim Office
• The Future
• Summary
June 2012 Games for Health Conference www.gamesforhealth.org
4. Cognitive Assessment
• Evaluation of Brain Functions, Cognitive
Abilities
• Clinical Decision-Making
– Ability to perform complex functional tasks in
everyday life
– Examples: Driving a car, making a
breakfast, buying groceries, working in an office

5. Cognitive Assessment
Current computerized tests to predict
cognitive function in a mostly non-
functional, abstract context.

6. Cognitive Assessment
Complex situations which we are trying to assess

7. Ecological Validity
• Extend to which a test is similar to the real world
• (Shadish, Cook & Campbell, 2001)
– Interaction
– Graphics
– Audio
– Content
• Main advantage of virtual reality applications

9. Framework
What is needed to actually build a wide range of functional virtual
environments for cognitive assessment?
• Game Engines- Unity, CryEngine, Unreal Engine, etc.
• 3D Models –
Autodesk, Modo, SketchUp, TuroboSquid, the3DStudio, Dexsoft
Games, etc.
• Powerful Hardware – PC, Smartphones, Tablets
• Interaction Devices – Kinect, PS Move, Wii, Leap, etc.
• Clinical Expertise
• Need for enhanced assessment and training
All of these elements are readily available to build a flexible
interactive virtual environment

13. Framework
• Cognitive and motor rehabilitation

15. AssesSim Office
• Collaboration with NNL – Kessler Foundation and
USC ICT
• Assessment of Executive
Functions, Attention, Memory in TBI patients
• 16 Iterations
– Input devices (joystick, mouse/keyboard, kinect?)
– Instructions
– Data collection
– Tasks
– Difficulty, Timings

16. AssesSim Office - Extensions
Once the framework is in place extensions towards a wide range of
functional context becomes possible. As such, the following extensions
have been built in the past six months:
• Navigation / Spatial Orientation
• Wheelchair Training
• Prospective Memory (To-Do-List)
• Attention (Divided / Sustained / Alertness)
• Executive Functions (Organize a meeting)
• Disaster Management
• Motor Rehabilitation (Balance / Reaching)
• Change each scenario over time (Generalization)
• …

17. The Future
• From “One-offs” to toolkits
• Give more control to the clinician by using intuitive controls
and interfaces to set up tasks and content difficulty

18. The Future
• Individualized assessment and training
• Validation vs. context-sensitivity
June 2012 Games for Health Conference www.gamesforhealth.org
19. The Future
• Collection of metrics
(Usability, Content, Difficulty)
• Quantitative analysis of patient and clinician
interactions with the developed system
• Conceptualizing data
• Assessment vs. Training
– User motivation
– Diversity of content, storyline
– Input from clinician or patient (or both?)

20. Summary
• Ecological validity
• Flexible framework for cognitive assessment
• Toolkits versus/with individualized content
