Funding for COPEX from Academy of Finland

The Academy of Finland decided to fund the project Computational Psychology of Experience in Human-Computer Interaction.

The COPEX project aims to study new touch and gesture interaction with novel methodologies. We combine finger biomechanics measurements, eye-movement tracking and experience measurement to get an understanding how users experience new interaction technologies. In experience measurement we utilize a novel quantitative-qualitative experience mapping methods. The data is modeled with Bayesian network, which can reveal relationships between different attributes and parameters via backwards reasoning. This provides novel possibilities to study human experience in interaction. Bayesian networks can be used not only to connect and statistically model single attributes and variables but to construct an entire network that combine all the variables and attributes into one large ensemble. This makes it possible to find and understand completely new connections and form an integrated theory of human interaction experience.

This is a collaborative project between MVPR and Psychology of Evolving Media and Technology Research Group (POEM) at University of Helsinki.

The three-year project was started in January, 2013. The principal investigator of LUT is Prof. Heikki Kälviäinen and the project manager is Dr. Tuomas Eerola.


Prof. Kälviäinen selected as an IEEE Senior Member

Prof. Kälviäinen from MVPR is now an IEEE Senior Member

IEEE has selected Professor Professor Heikki Kälviäinen from LUT MVPR as an IEEE Senior Member.

IEEE President & CEO, Ph.D. Gordon W. Day says in his nomination letter to Prof. Kälviäinen as follows: "It is a great pleasure to congratulate you on your elevation to the grade of IEEE Senior Member. Only 8% of IEEE's approximately 416000 members hold this grade, which requires extensive experience, and reflects professional maturity and documented achievements of significance."


Funding for ReVision from Academy of Finland

The Academy of Finland decided to fund the project Re-Engineering Retinal Imaging with Photonics and Computational Science.

On June 8, the ReVision consortium received a positive funding decision. The consortium partners are the University of Eastern Finland (responsible institution; photonics) and the University of Tampere (ophthalmology). The project has strong international collaboration with the University of Birmingham and Tokyo Institute of Technology.

ReVision is a multidisciplinary research project focusing on improving retinal imaging, image processing, and computational analysis of the image data to enable efficient automatic and semi-automatic methods for eye health. Retinal imaging is commonly used in ophthalmology and digital retinal cameras are in wide use in the western health care, for example, for the screening of diabetic retinopathy and age-related macular degeneration. With the proposed research, the current clinical practices are challenged by claiming that through the adoption of spectral imaging techniques, it is possible to significantly improve the examination of the eye when compared to the existing photographic systems based on grey-level and RGB imaging. Spectral imaging can be the missing part in the development of accurate and reliable methods for automatic monitoring and screening.

The project will begin in September 2012. The principal investigator of LUT is Associate Prof. Lasse Lensu.
