Progress with the Starline Project

Google has given an update on its Starline project in a blog post dated October 11, 2022. With this system, two people can hold a video conference in which the respective conversation partner is displayed as a 3D projection – a quasi-hologram. A display based on light field technology is used for this purpose. Several high-resolution cameras film the participants in real time. The company describes this process in a very non-technical or poetic way: “The technology works like a magic window, where users can talk, gesture and make eye contact with another person, life-size and in three dimensions. It is made possible through major research advances across machine learning, computer vision, spatial audio and light field display systems.” (Company News, 11 October 2022) The company hopes to improve hybrid working with Starline. Indeed, quasi-holograms would be interesting not only for concerts, but also for companies that allow and encourage homeworking or that are highly networked and distributed.

The Ukrainian President as a Hologram

“Leia in ‘Star Wars’, who as a hologram delivers a message, Darth Vader, who forges plans with the imperator even though they are far apart from each other, William Riker in ‘Star Trek’, who moves on the holodeck through artificial landscapes, Major in ‘Ghost in the Shell’, who walks through a city while fish are swimming in the air next to her, Officer K in ‘Blade Runner 2049’, who lives together with a holographic assistant and meets holographic dancers and singers (Frank Sinatra under glass and Elvis Presley on stage) – fictional holograms make an appearance in all these instances.” (Oliver Bendel, “Hologram Girl“, 2018) According to the Guardian, Volodymyr Zelenskiy referenced Star Wars and the second world war as he appeared as a hologram (or pseudo-hologram) at a conference in Paris to seek aid from big tech companies. “He told a crowd of hundreds at the VivaTech trade show that he was offering technology firms a unique chance to rebuild Ukraine as a fully digital democracy.” (Guardian, June 17, 2022) The British newspaper quotes him as saying: “It’s unusual for presidents or heads of government to use a hologram to address people but this is not the only aspect of Star Wars that we are putting into practice” (Guardian, June 17, 2022). The Ukrainian president is not only following in the footsteps of Leila, but also of ABBA, who are currently causing a sensation with their avatars at concerts in London.

The Hologram Girl Grew Up

Japanese company Gatebox has taken its holographic assistant to a new level in 2021 with the unveiling of Gatebox Grande. This is reported by HYPEBEAST. The hologram, which is now the size of an adult, is displayed on a 65-inch screen and can be used for applications such as a digital concierge or as an advisor and salesperson in a shopping mall. This makes the intelligent assistant a competitor to social robots like Pepper, Cruzr, and Paul. Inside the device “lives” a female anime character named Azuma Hikari, who can be “summoned” by voice or proximity activation. According to HYPEBEAST, she has a range of gestures, facial expressions, and voice tones to enable the most realistic interaction with the user. Life-size holograms will play a big role in the future. However, further research and development work is still needed.

Holograms that You can Feel and Hear

A hologram is a three-dimensional image produced with holographic techniques, which has a physical presence in real space. The term “holography” is used to describe procedures that exploit the wave character of light to achieve a realistic representation. Interference and coherence play an important role here. Colloquially, certain three-dimensional projections are also referred to as holograms. According to Gizmodo, researchers at the University of Sussex have created animated 3D holograms that can not only be seen from any angle, they can also be touched. “The researchers took an approach that was similar to one pioneered by engineers at Utah’s Brigham Young University who used invisible lasers to levitate and manipulate a small particle in mid-air, which was illuminated with RGB lights as it zipped around to create the effect of a 3D image. What’s different with the University of Sussex’s holograms is that instead of lasers, two arrays of ultrasonic transducers generating soundwaves are used to float and control a lightweight polystyrene bead just two millimeters in size.” (Gizmodo, 14 November 2019) A video of the Guardian shows quite impressive examples. Further information is available on the Gizmodo website.

Desire in the Age of Robots and AI

Rebecca Gibson’s book “Desire in the Age of Robots and AI” was published by Palgrave Macmillan at the end of 2019. From the abstract: “This book examines how science fiction’s portrayal of humanity’s desire for robotic companions influences and reflects changes in our actual desires. It begins by taking the reader on a journey that outlines basic human desires – in short, we are storytellers, and we need the objects of our desire to be able to mirror that aspect of our beings. This not only explains the reasons we seek out differences in our mates, but also why we crave sex and romance with robots. In creating a new species of potential companions, science fiction highlights what we already want and how our desires dictate – and are in return recreated – by what is written. But sex with robots is more than a sci-fi pop-culture phenomenon; it’s a driving force in the latest technological advances in cybernetic science. As such, this book looks at both what we imagine and what we can create in terms of the newest iterations of robotic companionship.” (Information Palgrave Macmillan) One chapter is entitled “Angel Replicants and Solid Holograms: Blade Runner 2049 and Its Impact on Robotics”. This is a further contribution to the robots and holograms in the well-known film. Already “Hologram Girl” by Oliver Bendel dealt with the holograms in this fictional work and the possible relationships with them and with their colleagues in the real world.

Holograms in Teaching

Some universities strive to use holograms in their teaching. Through this technology, the lecturer’s representative would have a physical presence in space. Even interactions and conversations would be possible if the holograms or projections were connected to speech systems. Dr. David Lefevre, director of Imperial’s Edtech Lab, told the BBC one year ago: “The alternative is to use video-conferencing software but we believe these holograms have a much greater sense of presence”. American Samoa Community College (ASCC) has now switched on a digital platform that will stream 3D holograms of University of Hawaiʻi faculty members to deliver classes and engage with ASCC students in real-time. According to the website, students at the HoloCampus launch on August 20 received a lecture by UH Mānoa Water Resources Research Center researcher Chris Shuler on the subject of “sustainability and resilience” – a theme “with special significance for the people of American Samoa and Pacific Islands nations as they face challenges such as increasing plastic waste and more dramatic weather systems brought about by climate change” (Website University of Hawaiʻi). Holograms could play a role in all sorts of areas, including social and sexual relationships.

Hologram Girl

The article “Hologram Girl” by Oliver Bendel deals first of all with the current and future technical possibilities of projecting three-dimensional human shapes into space or into vessels. Then examples for holograms from literature and film are mentioned, from the fictionality of past and present. Furthermore, the reality of the present and the future of holograms is included, i.e. what technicians and scientists all over the world are trying to achieve, in eager efforts to close the enormous gap between the imagined and the actual. A very specific aspect is of interest here, namely the idea that holograms serve us as objects of desire, that they step alongside love dolls and sex robots and support us in some way. Different aspects of fictional and real holograms are analyzed, namely pictoriality, corporeality, motion, size, beauty and speech capacity. There are indications that three-dimensional human shapes could be considered as partners, albeit in a very specific sense. The genuine advantages and disadvantages need to be investigated further, and a theory of holograms in love could be developed. The article is part of the book “AI Love You” by Yuefang Zhou and Martin H. Fischer and was published on 18 July 2019.
