1. Academic Contributions
Research Domains and the Digital Nature Concept
Ochiai’s academic work focuses on human–computer interaction (HCI), virtual reality, and multisensory interface technologies (including audio-haptic feedback and airborne displays). He has developed groundbreaking techniques — such as using ultrasonic waves to levitate small particles and employing femtosecond laser pulses to generate three-dimensional images in mid-air — that have been presented at top international conferences like SIGGRAPH and CHI [3, 4]. These projects have contributed to what he calls Digital Nature: a new paradigm in which digital computation is seamlessly integrated with the physical environment to reimagine our understanding of nature itself [2, 5]. By challenging the traditional dichotomy between the artificial and the natural, his research invites a redefinition of both scientific inquiry and aesthetic experience.
Research Achievements and Interdisciplinary Impact
Among Ochiai’s notable academic achievements are:
Airborne Haptics and Levitation: Development of “Pixie Dust,” an ultrasonic system that manipulates objects in mid-air, and the “Fairy Lights” technique, which uses ultra-short laser pulses to create suspended luminous points [3].
Multisensory Interaction: Innovations in tactile feedback in conjunction with visual displays, enabling users to “touch” holographic projections, have expanded the scope of HCI research [4].
Interdisciplinary Integration: His work draws on fields as diverse as computer science, physics, biology, and art, thereby bridging the gap between technical research and cultural expression. The establishment of the Digital Nature Laboratory at the University of Tsukuba is a testament to his commitment to nurturing an interdisciplinary approach [2, 5].
These contributions have not only advanced our understanding of digital–physical interfaces but have also influenced emerging applications in areas such as medical device innovation and creative design.
2. Artistic Achievements

Additional honors from events such as SXSW Creative Experience ARROW Awards and selection in the MIT Technology Review Innovators Under 35, reflecting his impact on both the art and technology communities [8, 10].
These recognitions underline the global significance of his work and its capacity to redefine how we perceive art in a technologically advanced society.
3. Social Implementation and Entrepreneurship
Founding Pixie Dust Technologies
In 2017, Ochiai co-founded Pixie Dust Technologies — a university spin‐off company that translates his research in wave and vibration control into marketable products. The company has developed applications based on his ultrasonic and laser-based innovations, ranging from audio-haptic devices to medical and educational tools [11]. For example:
Audio–Visual Communication Devices: Innovations such as “VUEVO,” which provides real-time transcription and translation for the hearing impaired, facilitate communication by allowing speech to be “seen” on a display [12].
Multisensory Engagement Products: Devices like “SOUND HUG” enable users to experience sound through tactile vibrations, thereby extending the realm of musical and artistic experience beyond traditional auditory channels [12].
Pixie Dust Technologies has also ventured into the commercialization of Digital Nature-inspired products, achieving notable milestones such as listing on the NASDAQ in 2023 — a rare feat for a research-driven start-up [11]. This successful transition from academic research to commercial application exemplifies his commitment to creating technologies that address real-world challenges.
Addressing Social Challenges
Ochiai’s initiatives extend to socially relevant projects, including:
Inclusive Technologies: Projects aimed at overcoming communication barriers for the disabled, such as specialized devices for the hearing impaired [12].
Public Health and Safety: Development of non-contact interfaces and IoT solutions that have applications ranging from digital twin technologies in construction to innovative disinfection systems during the COVID-19 pandemic [13].
Through these endeavors, Ochiai demonstrates how Digital Nature can serve as a bridge between high-tech research and tangible societal benefits.
4. Education and Social Activities
Academic Leadership and Mentorship
At the University of Tsukuba, Ochiai leads the Digital Nature Laboratory, where he guides graduate students in exploring interdisciplinary research that spans HCI, media art, and beyond. His approach emphasizes minimal direct instruction and maximal encouragement for self-directed, cross-disciplinary thinking. This philosophy has led to the publication of numerous research papers and the nurturing of students who have gone on to work in both academia and industry [2, 5].
Ochiai’s involvement is not confined to technical departments alone. He has also served as a guest professor at various art universities, thereby contributing to an educational environment where both science and art are seen as complementary pathways to innovation.
Government and International Engagement
Beyond academia, Ochiai has played an active role in shaping national science and technology policies. He has been an influential member of Japan’s Moonshot Research and Development Program, serving as both a committee member and, later, as an ambassador for the initiative [14]. His participation in international forums such as the World Economic Forum and TED Conferences further underscores his role as a global thought leader.
In anticipation of the 2025 Osaka-Kansai Expo, Ochiai has been appointed as the signature project producer for a thematic pavilion that embodies Digital Nature. The pavilion — designed as a “mirror” that generates digital avatars (termed Mirrored Body®) with which visitors can interact — symbolizes his vision of a future where digital replicas become integral to personal identity and societal interaction [15]. Through these large-scale projects, he is actively working to bring his vision of Digital Nature into the public sphere.
5. Philosophical Uniqueness
Bridging Technology and Tradition
A defining characteristic of Ochiai’s philosophy is his effort to bridge the gap between cutting-edge technology and traditional cultural practices. In works such as Object-Oriented Bodhisattva, he fuses generative AI and digital fabrication with ancient Buddhist iconography, thus reinterpreting traditional spirituality in a modern context [6]. This approach reflects his belief that digital technologies, rather than being mere tools, can be conduits for reviving and reimagining cultural and spiritual traditions.
Rethinking Humanity in the Age of AI
Ochiai is deeply engaged with questions regarding the role of human creativity and identity in an era increasingly dominated by artificial intelligence. In his writings and presentations, he envisions a future where the boundary between human and machine blurs — what he terms the “Supernature” era. He argues that, in a world where digital technologies are as pervasive as air, human beings must redefine their uniqueness and learn to coevolve with these innovations [10]. His emphasis on “adaptation and coevolution” suggests that rather than competing with AI, humans can harness technology to extend their creative and ethical capacities.
Cultural Fusion and a New Aesthetic
At the heart of Ochiai’s work is a conviction that technology can — and should — be harmoniously integrated with art and culture. He has described his media art as “Digital Nature art,” a modern analogue of vernacular craft that uses digital tools to reinterpret traditional aesthetics. His projects not only advance technical boundaries but also offer new ways of engaging with the cultural and spiritual dimensions of everyday life [2, 7].
