Stereoscape talks with one of its key collaborators, a leading researcher in stereoscopic 3D imaging – Dr. Jukka Häkkinen from Finland’s Aalto University
Aalto University’s Department of Media Technology in Finland is one of Stereoscape’s key partners in the academic world. For today’s blog post we interviewed Dr Jukka Häkkinen, one of Finland’s leading researchers in the field of stereoscopic 3D, and a long-term partner of Stereoscape.
Häkkinen started his 3D journey all the way back in 1992, when he decided to write his masters thesis on stereoscopic 3D at the suggestion of his professor. Based in the Department of Psychology, the research project started by looking at basics such as understanding the physical processes of human stereoscopic vision, including neurological factors, and so on. Häkkinen continued the research in his PhD, and was subsequently hired by Nokia where he spent ten years researching the effects of stereoscopic 3D technologies and imaging on people.
Häkkinen’s role at Nokia was mostly concentrated on exploring issues around 3D safety and viewing comfort. The work included measuring and recording test groups’ reactions on stereoscopic 3D imaging. Häkkinen noticed that people in test groups wanted to keep exploring the 3D content even after the official experiment was over, because it was “fun”. This sparked his long-term interest in exploring the positive psychological impact of stereoscopic 3D content on people – or the “wow” effect, as most of us call it. What does it consist of? Why is 3D so much fun? For the past six-seven years, this has been his main research interest.
Häkkinen and his colleagues at Aalto University have been working closely with Stereoscape since the company’s inception in 2007. Stereoscape has been providing 3D content and production resources that Häkkinen’s team has employed for research purposes. On the other hand, Häkkinen’s analysis of the content has enabled Stereoscape to have a more scientific basis for determining vital parameters for 3D content production, for example optimizing image ‘depth’ for child viewers, understanding the audience’s physiological and psychological reactions to the footage, and so on.
Aalto University’s connections in the international research community have further benefited the rich collaborative relationship between Häkkinen and Stereoscape. The parties have a long-standing relationship with Japan’s Waseda University, who are pioneering in research areas such as 2D to 3D conversion.
Stereoscape’s CEO Tomi Luostarinen says the company is privileged to be working so closely with the scientific community.
”Dr Häkkinen’s pioneering research on 3D viewing experience serves as an important foundation for our 3D content creation practice” Luostarinen says, “it gives us a real advantage when producing content and advising our clients – we know what is comfortable for the viewers, and it’s a real priority for us”.
