Introduction
Roy Want, a notable British computer scientist, was born in London in 1961. His significant contributions to the fields of mobile computing, indoor positioning, and the Internet of Things (IoT) have shaped the modern technological landscape. With a PhD from Cambridge University, Want’s expertise and innovative spirit have led him to hold over 100 patents and author more than 150 papers. Currently residing in Silicon Valley, California, he serves as a Principal Scientist at Google within the Android group. This article delves into Want’s educational background, pioneering projects, technical services, and recognitions throughout his illustrious career.
Educational Background
Roy Want’s academic journey began with his enrollment at the University of Cambridge, where he pursued studies that would pave the way for his future in computer science. He completed his PhD in 1988, focusing on multimedia distributed systems. This research not only contributed to his knowledge but also set the foundation for his subsequent innovations in mobile and ubiquitous computing. The insights he gained during this period were crucial in shaping his approach to technology development and application.
Pioneering Projects
Among Roy Want’s many contributions to technology, one of the most notable is the Active Badge system developed in 1988 during his time at Olivetti Research Ltd (ORL). This groundbreaking system allowed for the identification of individual mobile users and their location within a building. The Active Badge system was recognized with the ACM SIGMOBILE Test-of-Time Award in 2016 due to its significant impact on context-aware software systems. Its deployment at various laboratories, including DEC SRC and Xerox PARC, marked a pivotal moment in mobile computing history.
Ubiquitous Computing at Xerox PARC
Roy Want played an instrumental role in realizing Mark Weiser’s vision of Ubiquitous Computing while working at Xerox PARC. He was involved in the development of several innovative devices: PARC-Tab, PARC-Pad, and LiveBoard. These devices laid the groundwork for modern smartphones, tablets, and smart TVs. Notably, Want was the principal architect behind PARC-Tab, which became the world’s first context-aware mobile computer. This device could adapt its applications based on user context—a concept that would not gain widespread recognition until a decade later with the advent of smartphones like the iPhone.
Advancements in Mobile User Interfaces
In addition to his work on context-aware computing, Want also made strides in mobile user interfaces during the late 1990s. At PARC, he introduced inertial sensor technologies into mobile UIs through projects like Hikari—a handheld digital organizer that could automatically adjust its orientation based on how it was held. This feature has since become commonplace in today’s smartphones. Additionally, Hikari implemented innovative interaction methods such as tilt-based scrolling and selection mechanisms that anticipated modern user experience design trends.
Bridging Physical and Digital Worlds
By the end of the 1990s, Roy Want led PARC’s electronic tag project aimed at “Bridging Physical and Digital Worlds,” which focused on passive RFID technology. This project represented one of the first comprehensive visions for integrating electronic tags with mobile platforms to provide contextual information linked to digital content and controls. It established foundational concepts for what we now recognize as context-aware computing.
Contributions at Intel and Google
After his impactful years at Xerox PARC, Roy Want continued to push boundaries at Intel Research. He spearheaded the Personal Server project in 2001—a platform that allowed users to present personal digital content on nearby displays via wireless connections. This innovation later influenced services such as Apple’s Airplay and Google Cast. In 2005, Want introduced Dynamic Composable Computing, envisioning a future where users could assemble logical computing environments dynamically through wireless components.
At Google since 2011, Want has been integral to developing Eddystone Bluetooth-Low-Energy (BLE) beacons that enhance context-aware capabilities similar to RFID but leverage smartphones’ ubiquity for greater range detection. His efforts have continued to influence how devices interact with their environments through BLE technology.
Technical Service and Leadership Roles
A dedicated member of the ACM SIGMOBILE community, Roy Want has taken on numerous leadership roles throughout his career. He served as Chair of SIGMOBILE from 2009 to 2012 and has been involved with various top-tier conferences such as ACM MobiSys and IEEE ISWC as program chair. Additionally, he held the position of Editor-in-Chief for IEEE Pervasive Computing magazine from 2006 to 2009.
In recent years, he became Technical Editor for IEEE standards related to Next-Generation Positioning technologies under IEEE 802.11az and IEEE 802.11bk standards. These standards aim to provide enhanced indoor location accuracy—an essential component of context-aware applications across billions of devices globally.
Awards and Recognitions
Roy Want’s contributions have not gone unnoticed; he has received several prestigious awards throughout his career. In 2005, he was named an ACM Fellow as well as an IEEE Fellow—recognitions awarded to individuals who have made significant contributions to their respective fields. Moreover, he received the Lillian Gilbreth Lectureship award from the US National Academy of Engineering for his work on the Intel Personal Server in 2003.
The ACM SIGMOBILE Outstanding Contributions Award (OCA) followed in 2019 for his extensive work towards hardware and software developments that advanced context-aware mobile computing practices.
Conclusion
Roy Want’s career has been marked by innovation and dedication to advancing technology in mobile computing and ubiquitous systems. His pioneering work—from early projects like Active Badge at Olivetti Research Ltd to leading initiatives at Google—demonstrates a commitment to enhancing how we interact with technology daily. As devices become increasingly interconnected through IoT frameworks and context-aware systems continue evolving, Want’s influence will undoubtedly resonate within future technological advancements.
