Pilot study testing the AVUS-system

The AVUS-system (my research software) is currently tested in a pilot study with stroke patients. Support comes from the department for physiotherapy of the university of applied science in Osnabrück and a local neurologic rehabilitation center. 5 patients have been tested so far and the study is ongoing. Results will hopefully be published soon.

IK 2013

I participated in this years edition of the interdisciplinary college in Günne at Lake Möhne. For a week (15.-22. march) participants from the cognitive science community gather to discuss and attend lectures and workshops. This years topic was "Complexity, Wicked Problems and Wisdom". The event was a great success and very informative.

I also had the opportunity to give a lecture ("rainbow course") about the field of Virtual Rehabilitation and my phd-project. See the lecture's abstract here: Abstract VReha IK2013

Give the child a name … AVUS

After the prototype for my research software has been tested and advanced in several iterations I have a more stable release version now. It turns out that speaking about prototypes and iterations is not very catchy, therefore a name need to be coined. I decided to use:

AVUS: Abstrakte Virtuelle Umgebung für Schlaganfalltherapie (Abstract virtual environment for stroke therapy)

Impressions:

ICEC 2012

I participated in this year's "International Conference on Entertainment Computing" in Bremen and presented my project with a poster. The audience valued the project and provided very good feedback. The publication is available as a final draft on this side under Publications and the published version is available on www.springerlink.com.

ICDVRAT 2012

I attended this years "International Conference on Disability, Virtual Reality and Associated Technologies" (ICDVRAT) in Laval, France from 10th to 12th september. I presented the attached poster and demo'ed the final version of the software prototype that I developed and tested during my research visit at ICT, LA. The feedback to the demo was positive!

Research Visit @ICT

I am back home from my research visit at University of Southern California's Institute of Creative Technology. I spent the past 3 month at the institute working with the medVR motor rehab lab. Many thanks for the opportunity to Belinda Lange and her team, Rachel Proffitt, Panagiotis Apostollelis, Kevin Chang, Eric McConnell, Kevin Feeley, Skip Rizzo and Sebastian König.

At ICT I worked on my phd-project "Therapeutic Presence". I worked on the software development and came up with 3 different artistic and geometric visualizations of patient's movement. I included playback and analysis of an audio-stream that feeds back to the visualizations and provides for a more engaging experience. The software tracks the movement of patients using the Microsoft Kinect camera. A mirror therapy mode is implemented for neurologic patients mirroring the patient's healthy upper limb to the affected side. The software is written in Java and uses Processing for the visualizations. I separated the tracking of the skeleton and some basic calculations that are useful for medical applications into a middleware library that is available for download on my github site. The attached image shows a slightly outdated version of the software as demo'ed in the lab on an early feedback session.

With the resulting prototype I visited three different rehabilitation centers in Los Angeles and tested its application with 18 patients (stroke, brain injury, spinal coord injury). The evaluation revealed applicability as well as limits of the software. From the stroke and brain injury patients the feedback was positive and the test session was successful. The mirror therapy mode seemed to serve its purpose, though a more structured evaluation needs to be done to prove this. The clinicians made use of the visual feedback and commented positive. I haven't finished the analysis of the test sessions, but the results so far are promising.

Research visit at ICT, USC, LA

I am really glad to be invited by the Institute of Creative Technology, University of Southern California, Los Angeles for a research visit in summer. Today I got approval for funding and the flights are booked! I will be in Los Angeles from June till August and work on an evaluation of my software. Really looking forward!

Software prototype

In the past month I developed a first prototype for my virtual rehabilitation software. It is written in Java, uses the Processing and SimpleOpenNI framework and is based on Microsoft Kinect/Primesense sensor data. The prototype demonstrates the basic idea of using generative design methods for virtual rehabilitation. The next step is to develop it further into a open source middleware library for Processing for this purpose. This library will then be available for download.

Some pictures demonstrate the prototype:
