The Present and Future of 3D

25.01.2011
Takashi Kawai, a Professor at the Faculty of Science and Engineering, Waseda University, analyses the current boom in 3D entertainment and the potential future applications of 3D technology.

The Beginning of the 3D Era and the Boom Phenomenon

2010 has been called the beginning of the 3D era, a year in which the term 3D frequently appeared in the media. Here, I use 3D to mean three-dimensional images, or to give them their proper name, stereoscopic images, reproduced to appear in front of or behind the screen. The word stereoscopic was coined by the inventor of the stereoscope, Sir Charles Wheatstone, who first used the term in a paper published in 1838. It derives from the Greek words stereos, meaning solid, and scope, meaning viewing instrument.

The phenomenon of periodic booms in 3D is often pointed out. These were mainly 3D movie booms that occurred in the 1950s and 1980s, and the present day is sometimes referred to as the third boom. The fact that 3D has until now never developed beyond a temporary fad is an indication of the difficulty in popularizing it. Nevertheless, the repeated appearance of such booms does suggest that 3D is a kind of dream technology for human beings. Here I would like to mention the characteristic ripple effect of present day 3D. The rapid development outside the film industry of 3D-compatible TVs, game consoles and mobile devices currently being announced and released by various manufacturers has exceeded the expectations of most researchers such as myself, as well as industry related people.

Issues of Present Day 3D

Although the spread of 3D is expected to result in the creation of new industries and culture, it is still uncertain what the merits and added value will be for users. When asked, “What is the advantage of 3D movies or TV?” it is not enough to simply answer that “things leap out of or into the screen”. Scientific verification of whether 3D can really convey different sensations than 2D, or of what elements of 3D people find appealing, is urgently required so that the current boom does not turn into just another temporary fad.

At our laboratory, we have been conducting an experimental study of current 3D issues as they relate to the user experience. From Figure 1 we can see that the line of sight is concentrated mostly on people, and especially faces, when watching a movie in 2D. Figure 2 is the result when viewing the same movie in 3D. Here we see that the line of sight is concentrated not only on people’s faces but also on the objects in the foreground. To clarify the cause of such a distinctive difference, we have performed a range of detailed analyses, especially of the link with the spatial construction of visual data.

Initiatives toward the Future of 3D

While tackling the present day tasks of explaining viewer recognition and emotional aspects, our laboratory is also facing the challenge of looking to the future of 3D. One such direction is new applications of 3D. An example of this is three-dimensional character blocks for literacy learning developed through joint research with the Division of Developmental Neuropsychology at the National Center for Child Health and Development. The intention is to utilize spatial reasoning capacity in literacy learning by adding information of depth according to the stroke order of a character to its ordinary two-dimensional shape. Such a conceptual shift from representing real shapes three-dimensionally to envisioning a specific effect and venturing to express it three-dimensionally could produce an unprecedented demand for 3D.

Another direction we have taken relates to the extension towards perceptual experience through 3D representation other than vision. Figure 3 shows an example of this, a tactile behavioral illusion system. By combining 3D and tactile stimulation based on certain measurements, this system enables people to experience sensations that have not actually been triggered. Specifically, we can create an illusion related to bodily sensation, a feeling that a stationary object touching one’s hand is moving across the surface of that hand. Such a shift in awareness from a single sense to the integration of multiple senses, or in other words, from vision to brain function, could be vital in shaping the 3D-based media of the next generation.

The desire to see remote things or to present them so that they can be seen is a fundamental trait in human beings. That is to say, interest in and expectations for 3D are perfectly natural, and so the future of 3D also seems linked, to some extent, to human potential.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
