Steve Mann (inventor)

Mann was born in Hamilton, Ontario, Canada. While in high school, Mann built a wearable 6502-based computer in a steel-frame backpack to control photographic systems.^[8]

He studied at McMaster University, where he completed B.Sc., B.Eng. and M.Eng. in 1987, 1989 and 1992, respectively. He later obtained a PhD in Media Arts and Sciences (1997) from the Massachusetts Institute of Technology (MIT) in 1997.

Mann is a tenured full professor at the Department of Electrical and Computer Engineering at the University of Toronto, with cross-appointments to the Faculty of Arts and Sciences and Faculty of Forestry. He is also a licensed Professional Engineer in Ontario.

Mann’s research has focused on wearable computing, computational photography, and human–computer interaction. Beginning in the late 1970s, he developed early wearable computing systems designed to integrate imaging, sensing, and real-time processing with human perception. Among these developments was the “EyeTap” or “Digital Eye Glass,” a wearable device that combines camera input and display output to enable mediated visual experiences.^[9]

In signal processing and computational imaging, Mann introduced the chirplet transform in 1991, a representation based on chirp signals that extends wavelet-based methods.^[10][11][12] He later developed techniques for estimating camera response functions and combining multiple exposures of the same scene to extend image dynamic range, contributing to the development of high-dynamic-range imaging methods.^[13][14] His work also included early algorithms for image stitching and perspective correction,^[15] sometimes referred to as “video orbits.”^[16][17][18]

Mann has also contributed to interface design and human–computer interaction, including the development of approaches described as natural user interfaces, which emphasize interaction through physical environments rather than traditional command-line or graphical interfaces.^[19] Related work includes input methods such as acoustic “scratch input,” which uses sound generated by physical contact with surfaces as a form of interaction.

In addition to imaging and interface research, Mann has explored concepts in physics and engineering such as integral kinematics and integral kinesiology, including measures like “absement,” which represent time-integrated displacement.^[20][21][22] He also developed experimental systems such as the hydraulophone, a musical instrument that produces sound through the manipulation of pressurized fluid.^[20]

Mann has also explored concepts related to human perception and mediated reality. His work includes proposals such as the “sensory singularity,” sometimes referred to as “sensularity,” developed in collaboration with other researchers Marvin Minsky and Ray Kurzweil, as well as experimental visualization systems such as the surveilluminescent wand, which is designed to make the field of view of imaging devices perceptible.^[23] He has further contributed to the development of wearable and gesture-based systems, including telepointer and related “SixthSense”-type interfaces, which integrate cameras and projection systems to enable interaction with digital information through physical gestures.

Mann also works in the fields of computer-mediated reality.^[24] He is a strong advocate of privacy rights. His work also extends to the area of sousveillance (a term he coined for "inverse surveillance"). Mann and one of his PhD students, James Fung, together with some of his other students, have been building a cyborg community around the cyborg-logging concept.^[25]

Mann has collaborated with Ian Kerr of the University of Ottawa on research on anonequity project related to surveillance, sousveillance, and equiveillance.^[26] He is credited with coining the term sousveillance, referring to forms of observation conducted by individuals rather than centralized authorities, and has contributed to the development of related concepts such as humanistic intelligence, which examines the integration of computation with human perception and experience.^[27][28]

His work has also been associated with early forms of mobile and networked media. In 2003, Joi Ito attributed to Mann an early role in the development of moblogging, citing systems he created for transmitting images, video, and text in near real time. Between 1994 and 1996, Mann conducted continuous personal broadcasting experiments in which aspects of his daily life were shared online for remote interaction.^[29]

These activities, sometimes described as “cyborg-logging,” involved the use of wearable computing systems to document and transmit lived experiences.^[30] Such work has been characterized as an early precursor to blogging and other forms of online personal media and social networking.

Mann was inducted into the McMaster University Alumni Hall of Fame in 2004, in recognition of his career as an inventor and teacher.^[31]

During his time at the Massachusetts Institute of Technology, Nicholas Negroponte credited Mann with contributing to the early development of wearable computing research at the MIT Media Lab.^[32] Negroponte described, Mann’s work as influential in the establishment of the lab’s wearable computing activities and in the broader development of the field.^[33][34]

In 2004 he was named the recipient of the 2004 Leonardo Award for Excellence for his article "Existential Technology," published in Leonardo 36:1.^[35][36]

He has held roles in professional and academic organizations, including serving as General Chair of the IEEE International Symposium on Technology and Society,^[37] Associate Editor of IEEE Technology and Society, is a licensed Professional Engineer, and Senior Member of the IEEE,^[38] as well as a member of the IEEE Council on Extended Intelligence (CXI).^[39]

Mann received the 2025 IEEE Masaru Ibuka Consumer Electronics Award^[40] for his work in wearable computing. He also received the 2024 Lifeboat Foundation Guardian Award for related work on sousveillance.^[41]

Mann has been referred to as the "father of wearable computing",^[42][43][44] having created the first general-purpose wearable computer, in contrast to previous wearable devices that perform one specific function such as time-keeping (e.g. wristwatch); calculations (e.g. wearable abacus); or Edward O. Thorp and Claude Shannon's wearable computers, which were timing devices concealed in shoes or cigarette packs and designed for gaining an advantage at roulette.^[45][46]

Mann has also been described as "the world's first cyborg" in Canadian popular press such as NOW, The Globe and Mail, National Post, and Toronto Life, but has himself rejected the term "cyborg" as being too vague.^[47]

In 2023, Steve Mann ran for Mayor of Toronto.^[48] As part of his campaign he advocated for recreational swimming in Lake Ontario, and supported a petition to save the beach at Ontario Place.^[49][50]

Mann is author of more than 200 publications, including a textbook on electric eyeglasses and a popular culture book on day-to-day cyborg living. Selected works:
