Kurillo received B.Sc.
and D.Sc. degrees from Faculty
of Electrical Engineering, University of
Ljubljana, Slovenia in 2001 and 2006, respectively. He has received the
highest
national award for his undergraduate thesis work. He was a Research
Assistant
with the Laboratory of Robotics and Biomedical Engineering at the same
institution from 2002 to 2006. His research work was focused on the
application
of principles of robotic grasping to human grasping for the assessment
and
rehabilitation of hand function in virtual environments. He has also
participated
in two European Union funded projects, iMatch and Alladin,
aimed at
rehabilitation and assistive technology.
Dr.
Kurillo was a Postdoctoral Researcher at University of California,
Berkeley, from 2006 to 2009. He is now Assistant Research Engineer with
the Teleimmersion Lab at University of California, Berkeley. His research interests include
virtual
reality, stereo vision, camera calibration, robotics, and rehabilitation engineering.
2009 - Now: Assistant Research Engineer, Teleimmersion
Lab, UC Berkeley
In the current stage of the teleimmersion
project research we are focusing on development of collaborative
applications that allow users to interact with data and each other in a
shared virtual environments. Two examples of such applications
are cyberarcheology (in collaboration with UC Merced) and
virtual geology (in collaboration with UC Davis). We are also focusing
on geometric and photometric multi-camera calibration, in particular on
the calibration of color.

2006 - 2009: Postdoctoral Researcher, Teleimmersion
Lab, UC Berkeley
Tele-immersion is aimed to enable users in geographically distributed
sites to collaborate in real time in a shared simulated environment as
if they were in the same physical room. We currently have several
projects underway to improve the existing technology, including
segmentation algorithms to recognize human beings and segment their
data into individual limbs, mathematical models of human movement in
order to identify actions, refinement of stereo algorithms to better
discern depth information in less time, customized hardware
architectures to optimize performance of existing algorithms, and
ongoing experiments and refinements in the sharing of real-time video
and audio data over long distances.

2004 - 2007: European Union Project ALLADIN
ALLADIN project was focused on the development of a
user-friendly natural language based decision support software for
neuro-rehabilitation, in particular in stroke. Within the project, a
novel force measuring platform was designed to assess isometric forces
of different parts of the body (e.g. fingertips, forearm, back, foot
etc.) during intention driven tasks (e.g. trying to pick up a cup for
drinking).

2002 - 2006: European Union Project i-Match
The project was focused on development of virtual reality
training simulator for assistive technology users (e.g. wheelchair,
Handy robot, Manus - wheelchair mounted robot)
and methods for assessment of user interfaces (e.g.
joysticks, switches, mouse).

2001 - 2006: Doctoral Thesis - Measurement
and Evaluation of Grasping in
Virtual Reality:
The work was focused on the assessment and
rehabilitation
of human grasping through measurement of force in virtual environments
(VEs). The first part of the work introduced a tracking system
for
the evaluation of grip force control. The system consists of a
grip-measuring device with end-objects of different shapes which was
used as input to a tracking task to provide bio-feedback. The method
was applied to healthy subjects, patients with neuromuscular diseases,
head-injury patient after BTX treatment and a group of post-stroke
patients. The second part of the work presents a novel rehabilitation
system for the assessment and training of multi-fingered grasping in
VE. An isometric finger device was designed to simultaneously
assess forces applied by three fingers. Four virtual reality tasks were
developed with the aim to improve grip force coordination and increase
muscle strength of patients after stroke through repetitive exercises.
The presented virtual system was evaluated in a group of healthy
subjects and a post-stroke patient.
