Raine Kajastila D.Sc.(Tech.) raine.kajastila()aalto.fi


I am a post-doctoral researcher at the Department of Computer Science, Aalto University School of Science, Finland. In my research, I am currently focusing on audio/visually augmented exercise and sports training environments with Perttu Hämäläinen. In addition to research, we are commersializing Augmented Climbing Wall, a research project that spun out of the labs.

I defended my doctoral thesis Interaction with eyes-free and gestural interfaces on 8.2.2013. The research was done as part of the Virtual Acoustics team lead by Lauri Savioja and Tapio Lokki.

Previously, I have co-founded two spin-off companies named Hipui and Blaast (later renamed as Pryte holdings), which both originated from the research work we did here in Aalto. I worked at Blaast during the years 2010-2011 and ended my daily contribution to the company when returning to finnish my thesis.

In my work and during the spare time I am endlessly innovating better (sometimes even impossible) solutions for all things that just don't work well enough.
